2. Description of the Related Art In a corporate network, a centralized network mainly connecting a group of host computers having a database server, an application server, and a communication control function to a terminal for online transaction processing is mainly used for financial services. It was used as a network for institutional accounting or corporate business. In addition, in an information network using a personal computer (hereinafter, referred to as a PC) as a terminal and a LAN connected to a host computer based on the TCP / IP protocol, a client / centralized server network is typical and almost large. Some employees have begun to connect their personal computers, PCs, to the network.

Further, an OS of a workstation (hereinafter referred to as WS) server or a PC server supports online transaction processing and distributed database functions, and is replaced with a host computer as an enterprise server, and an application server of packaged business software. The server machine operates as a database server, multiple servers are integrated in the network, and a distributed server / client type network that performs enterprise-level or global network computing that replaces the conventional host computer is written. It has become popular with the sizing catchphrase.

[0004] In addition, global network computing, which can be seen in derivatives that speed up decision making by making full use of servers distributed on a global scale, is being combined with Internet technology and database replication technology to enable global business activities. Supporting. Intranet and Internet as intra-company networks, WW distributed over networks
The W (World Wide Web) server and the WWW browser of the desktop are rapidly spreading. In particular, a database connected to the WWW server can be used for image,
Since multimedia such as data and voice can be easily accessed as an object in an integrated GUI environment,
The demand for this WWW multimedia network is growing rapidly.

[0005] The computer is easy to use and personalized by the operation system and the WWW technology excellent in GUI, and all the employees are connected to the network to share information, transmit the information immediately, and improve the work efficiency. The business utilization of information and communication technology is progressing because decisions can be made quickly and intellectual productivity is increased, and companies or company models are becoming network-type distributed forms. In addition, information and communication networking technologies, such as networked virtual companies, support global business activities. In this way, network and information and communication technologies are required to have scalability and innovation that can respond quickly to changes in corporate activities more than before, and at the same time, all employees working in offices and other offices need to use the network. High speed and high performance are required in addition to performance, maintainability and economy.

Further, in order to improve intellectual production in offices, in addition to providing amenities (comfortable living environment) by building equipment such as air conditioning and sanitary equipment, lighting equipment, disaster prevention equipment, etc., information and communication technology was used. Intelligent network service functions are required. With the spread of networks and technological innovation, the broadband and high-speed networks have progressed, and the development of higher-performance digital information and communication technologies, or network devices and computing devices has progressed, and the product life of network devices themselves has also been shortened. Cycle times are becoming shorter, more advanced products with new features added in a short time are being launched, and old products are becoming increasingly obsolete. On the other hand, competition between companies and innovation in business activities require that new network equipment corresponding to the latest technological innovation be upgraded or expanded in a short time. For this reason, it is important to economically provide a migration path for gradually introducing a network and expanding devices, to enhance network security, and to provide intelligent network services.

As for multimedia transmission over the Internet and intranets, an RSVP (Resource Re-SerVation Protocol) that preferentially passes stream-type one-way data traffic of telephones and video conferences based on a connectionless IP protocol is known. Peer-to-peer networks such as teleconferencing systems based on Internet-level IP multicast have also been developed. RSVP itself is not a routing protocol, but works with unicast and multicast routing protocols, such as the Internet Control Protocol, which occupies TCP over IP. The receiving side issues a request for guaranteeing transmission quality (hereinafter referred to as QoS). On the node routers and hosts,
The packet classifier determines the route and QoS of the incoming packet, the packet scheduler makes a forwarding decision on a per-packet basis, and the admission control determines whether there are enough resources to support the requested QoS. Decision and policy control determine whether the user is authorized to use the resource.
RSVP transmits and manipulates QoS control parameters as opaque data. RSVP is designed to be extensible to multicast groups with very large members, groups, and tree topologies by means of router "soft states" (using software state transitions).

Conventionally, information communication equipment such as LAN and telephone center concentrators of intelligent buildings, and monitoring and control devices for BAs, and center equipment for electric equipment such as distribution boards have reduced network maintenance management costs and security. Electric shaft (hereinafter referred to as EPS) to secure
Collected in the center such as the electric room below. In other words, the network center collects the servers of the corporate level and network equipment important for network management, the telephone exchange is installed in the switching room, the disaster prevention system and the central monitoring panel of the BA are installed in the central monitoring room of the building. Management has been centralized. Information communication equipment such as a floor concentrator for controlling information communication terminals for each floor, a BA monitoring and control device, and a sub-central device for electric equipment are provided in a wiring closet of each floor, a floor terminal board (floor IDF). ), And is generally mounted in a 19-inch rack, from which a star-type wiring is carried out to the outlet of each floor by a preceding wiring system.

[0010] The wiring of the machine room subsystems from the network center, the switching room, and the central monitoring room are collected as a main line by a main terminal board (hereinafter referred to as MDF), and the floor ID of the wiring closet of each floor is obtained from the MDF.
A trunk wiring sub-system as a backbone to F is configured, and wiring from the floor IDF to terminals or outlets in the floor configures a branch wiring sub-system. Ideally, a star-shaped wiring from the terminal board (IDF) to the outlet of the wall or floor with four pairs of twisted pair wires is used in the shortest distance. The information lines of the trunk wiring subsystem are stored in the EPS together with the power distribution system extending straight from the bottom floor to the top floor of the building. Since the room on each floor where the EPS passes is the earring closet, the wiring closet and the electric shift (EPS) are treated as the same here.

On a relatively large floor, an indoor terminal board (hereinafter referred to as an indoor ID) is mounted on a work group or a wall surface of a room.
F), and a plurality of twisted pair wires using a multi-pair cable are wired in units of the indoor IDF from the floor IDF of the wiring closet to the indoor IDF of the work group. Functionally, the wiring from the floor IDF to the indoor IDF has a form in which a wiring closet is dispersed on the floor, and is referred to as a floor main system wiring subsystem here. In some cases, an indoor concentrator that controls information communication terminals for each room is provided on the floor IDF. In a room, an information terminal device such as a PC can be laid out in an island structure according to the arrangement of desks. Therefore, there is a zone wiring system in which this island is called a zone and a zone box is installed on the floor. A fixed floor wiring is used from the floor IDF or the indoor IDF to the zone wiring box, and a flexible desk wiring system is provided from the zone wiring box to the deskside outlet.

In the floor wiring, there is an access floor in which power wiring to be supplied to an information terminal such as a PC and telephone / LAN information wiring are combined to provide a wiring storage under the floor and a storage space for a wiring box. And L
In the AN wiring, there are a type in which only a passive connector is incorporated in a zone wiring box and a type in which a repeater HU having several active ports is incorporated as a zone concentrator. Deskside information outlets include a type in which only a passive modular connector is incorporated and an type in which a table tap type repeater HUB having several active ports is incorporated as a deskside concentrator. As a LAN access method used by terminals, a collision detection type Ethernet (CSMA / C
D system), but with the spread of LAN and the increase in the number of terminals in the information wiring, the advanced wiring system using twisted pair lines, which has been used for telephone wiring in the United States, has recently become an IDF crossover. Utilizing the management function of wiring change by batch panel.

In Ethernet, a 10BASE-T system with a transmission speed of 10 Mb / s of twisted pair lines is commonly used as a desktop. The floor wiring of twisted pair wires is collected in the floor concentrator (floor concentrator) installed in the wiring closet, and the signal is relayed to the floor concentrator (repeater).
It has a function to connect to a higher-speed trunk LAN, and has a bridge / router function to segment network traffic. The network center has a main router that connects to the external Internet, a switch that connects to the telephone line, a host computer, a file server, and a high-speed main LAN.
There was a center concentrator (center concentrator) that connects to the center.

The center wiring device and the floor concentrator are mounted on a so-called 19-inch rack, and are available in forms such as a sharn type, a box type, and a stack type. They are interconnected by multi-vendors depending on the communication protocol. In recent years, the speed of 100Mb / s1Gb / s of twisted-pair Ethernet has been increasing,
The transmission distance is 50 to 100 m with unsaturated twisted pair wire (UTP) of CAT5 grade.
In the advanced wiring system, for the time being, even if the transmission speed of 10 Mb / s is almost the case, C
Use AT5 unsilded twisted pair wire,
The optical fiber wiring that can be transmitted over longer distances and at higher speeds and that is fixed to a wall or the like and is flame-retardant is used in the part.

In order to increase the traffic throughput and keep the transmission delay time short as the number of terminals increases and the bandwidth used by each terminal increases, in addition to increasing the transmission speed of the individual wiring, floor consolidation is performed. It has become necessary to improve the line processing capacity of the device. An Ethernet switching type controller chip utilizing the high-speed data processing capability of a semiconductor processor has been commercialized, and a switching HUB capable of simultaneously and independently communicating at a transmission rate of 10 Mb / s and 100 Mb / s in a wire-laying device has been commercialized. Now used. These Ethernet switching ports are
Each port is connected to a specific segment in the concentrator
When filtering is performed based on the AC address, it is called a port switch or a configuration switch. When filtering is performed on an arbitrary segment for each port based on a MAC address, it is simply called a LAN switch. Each of them is called a layer 2 LAN switch. In the server / client type network, the connection to the server and the connection to the backbone have been accelerated, so the connection to the server and the backbone is connected by a 100 Mb / s big pipe, and the connection to the other ports is 10 Mb / s. There is an Ethernet switching HUB having a function of appropriately selecting a transmission speed of a port to be set to s according to traffic. Also, whether the terminal connected to each port is 10 Mb / s
There is an Ethernet switching HUB having a function of automatically recognizing whether it is 0 Mb / s. Even if a repeater HUB having a transmission speed of 10 Mb / s or 100 Mb / s is used for a deskside concentrator or a zone concentrator to which one to several terminals are connected, there is almost no collision, and the repeater HU
The area connected to B and bridged by the switch port is called a micro segment.

Since most of the traffic is concentrated on the backbone (main line) of the network and the server connection, scalability of high speed is required, and the server connection is 100 Mb.
s to 1 Gb / s Ethernet. In the backbone, the center concentrator has 100M
When a b / s LAN switch is installed and a LAN switch with a 100 Mb / s interface is installed on the floor concentrator, a frame riser type backbone is used, and further scalability and transmission quality guarantee (QoS) are required. A cell riser type backbone is used in which an ATM switch of an ATM system is installed in a center concentrator and a LAN switch with an ATM interface is installed in a floor concentrator.

Conventionally, an FDDI system is used for a trunk LAN, a main router with an FDDI interface for external connection to a center concentrator is installed, and an FDDI-Ethernet bridge router is used for a floor concentrator. However, with the spread of the layer 2 LAN switch, a main router and a layer 2 LAN switch connected to the outside were installed in the center concentrator, and the layer 2 LAN switch was installed in the floor concentrator. Installation, the backbone is a single subnet flat for routing protocols, the LAN switch segment is a broadcast domain and an independent LAN is configured, and the traffic between the segments is There is a method to pass an in-router.
Furthermore, the segment is registered in a table as a group of MAC addresses, an implicit VLAN forming an implicit virtual LAN segment, and an explicit forming an explicit virtual LAN segment inserting a tag that can be identified for each group into a packet. There is a VLAN.
In a layer 2 VLAN using such a layer 2 LAN switch, a segment independent of the physical wiring can be arbitrarily set across the floor concentrators using the filtering function of the switch, and can be set according to the corporate organization or the work group. Segmentation is possible. When the layer 2 LAN switch is configured by ATM LAN emulation, it is a virtual LAN configured on the VPI / VCI connection, but the LAN emulation does not guarantee the transmission quality (QoS).

However, when a flat subnet is divided into a plurality of layer 2 subnets, all broadcasts are concentrated on the main router, and traffic between segments is also concentrated on the main router. A failure of the main router could cause a bottleneck, or a one-point failure, causing the entire network to go down.

Therefore, when accessing a server centrally managed in a network center or configuring a plurality of overlapping segments across segments, traffic to communicate across the segments of the layer 2 LAN switch increases. As a floor concentrator, a switch called a layer 3 LAN switch, which is filtered based on the address of the routing protocol or the type of the protocol, has been developed. When a layer 3 switch is used, a layer 3 virtual network segment is formed by an address of a logically defined protocol without depending on a physical wiring such as a MAC address or a port, and may be called a virtual subnet. The Layer 3 LAN switch has a router function, so that traffic across the Layer 2 subnets can be switched directly without passing through the main router. Can be provided to enhance security. Layer 3 LA
N switches M over ATM LAN emulation
In the case of the configuration using the POA method, since the standardization has not been completed yet, there is a case where the vendor implements it according to its own specification, and a limited transmission quality guarantee (QoS) is also made. A backbone LAN system that uses an I-PNNI system for routing between ATM switches and uses a layer 3 LAN switch for an edge LAN switch has also been developed.

The IP switch system or the tag switch system, which has recently attracted attention, is a layer 3 LAN switch on an ATM switch which has been independently developed by a LAN vendor and proposed for standardization. In this way, in response to an increase in backbone traffic, layer 2 virtual LA integrating routing technology and switching technology
Higher-end systems such as center concentrators and floor concentrators for N and layer 3 virtual networks are being developed.

FIG. 8 shows a specific configuration of the distributed network service equipment 11 used in this embodiment. The ATM is connected to the backbone wiring 4 through the backbone connection ATM interface 81 including the backbone buffer memory 80 constituting the backbone switch 62 of the backbone connection unit 94.
In the intranet routing / bridge protocol processing unit 82 that constructs the router bridge 64, the route calculation learning / filtering 83 of the layer 3 and the learning / filtering 84 of the address of the layer 2 are performed, and the virtual routing table 63 of the trunk connection unit 15 is performed. Is created and queried in the virtual group routing table 85. Once the address has been learned, it operates in cut-through, bypassing the intranet routing / bridge protocol processing unit 82. In this embodiment conforming to the standard by the ATM Forum, in the same manner as the intranet routing / bridge protocol processing unit 82 of the integrated network service device 51 described later, the ATM is converted to a LAN packet by LAN emulation, and the MPOA of the upper layer is further converted. Function of processing a virtual router according to the above, 1-PNN1, IP connection (RFC157
A function capable of supporting a standard protocol such as 7) is provided in the intranet routing / bridge protocol processing unit 82.

The virtual group registration table 86 and the virtual routing table 85 of the distributed network service equipment 11 can set the client address and virtual group ID of the virtual group, and the destination virtual group ID is not the local site virtual group ID. In such a case, a packet local to the main router of the WAN connection unit 55 of the integrated network service device 51 is filtered so as to forward the packet from the distributed network service device 11 to the main router. If the destination virtual group ID is the local site virtual group ID, unicast to the port of the destination client address.

When addition / movement / change of a node is detected in the virtual group registration table 86 and the routing table 85 of the distributed network service equipment 11, the update information of the virtual group registration table 86 and the routing table 85 is given higher priority. By multicasting to each distributed network service device 11 at a time, the distributed network service device 11 performs the distributed processing of the routing calculation of the local virtual group. The route calculation processors of the distributed network service devices 11 share the intranet routing table of the local virtual group with each other, and the parallel control kernel units (not shown) of each distributed network service device 11 share the same while synchronizing with each other. The intranet routing table information in the memory is exchanged, and the optimal virtual group routing table 85 is sequentially maintained and managed.

In the virtual group identification unit 87, the client address 1 and the client address 2 are encoded by one hash function and collated with the virtual group configuration table similarly hashed. Alternatively, there is no problem of an increase in delay time as compared with the method of adding a tag. That is, M
O which defined AC address as client address
At the second layer level of the SI protocol hierarchy model, a virtual LAN group is added to a terminal that conforms to the traditional standard without adding an extra header or tag to the packet according to the traditional standard. Support.

Further, the virtual group identifying section 87 stores a pair of MAC addresses 1 as the destination and the source of the packet.
And the MAC address 2 is compared with the virtual group configuration table to identify a virtual group to which both MAC addresses are combined. In addition, at the third level of the OSI protocol hierarchy model in which a plurality of network addresses depending on the communication protocol are defined as client addresses, extra headers or tags are added to the packet in accordance with the conventional traditional standards. Without any addition, support virtual network groups for traditional compliant terminals.

Further, the virtual group identifying section 87
Compares a pair of network address 1 and network address 2 which are the destination and source of the packet with the virtual group configuration table, and identifies a virtual group in which both network addresses are combined. In addition, at the application level of the OSI protocol hierarchy model in which the user address or the application address defined by the application software is used as the client address, an extra header or tag is added to the packet in accordance with the traditional standard. Instead, it supports the setting of a virtual custom group in which different media access methods and communication protocols are mixed.

The virtual group identifying section 87 compares a pair of the application address 1 and the application address 2 which are the destination and the source of the packet with the virtual group configuration table, and identifies the virtual group including both application addresses. . Here, the client name is usually registered for each client address in the virtual group registration / routing table (combination of the above 55 and 56) of FIG. Different client names can be registered for each virtual LAN group, virtual network group and virtual custom group.
When a group, a virtual network group, and a virtual custom group are respectively defined, a row defining a virtual group and a row defining a virtual network group are included in the virtual group registration / routing table of FIG. And a line defining a virtual custom group. Further, the client definition table 103 (FIG. 10)
(Shown in (b)).

The virtual group identification unit 87 gives the highest priority to the collation of the virtual custom group, collates the virtual network group first, and finally the virtual group. This client name is the name of the switch,
The device type is also registered, as is the identification code of the device type such as a terminal. When the device type is a switch, the virtual group distribution management unit 88 registers the MAC address directly connected to the port of the switch or the switch connection map 89 indicating whether the device is indirectly connected. Together with the virtual group registration table 86 and the switch connection map 89, connection map information of the entire network can be obtained. Since the connection between the adjacent ports is known, the topology can be drawn in a connection relation diagram, and the connection relation diagram is called a map (MAP). If the topology is a tree structure, route search is easy, but if the topology is a mesh, it is necessary to compare the transmission time distances of a plurality of routes. When switches having the same transmission speed are connected in multiple stages, the number of stages is regarded as the distance.

In the virtual group registration / virtual group routing table shown in FIG. 10A, the optimum connection port address is registered as a routing connection port. In other words, in the configuration of the distributed switch, since other switches are cascaded to the ports of each switch, the connection port is optimally connected to the home switch to which the terminal is connected. This is the port name corresponding to the root.
When a port change message is output when the client address matches but the port is different as a result of the virtual group identification for the movement of the terminal, the intranet virtual group learning / identification unit 90 sends the topology change message to the virtual group distribution management unit 88. send. At this time, the virtual group distribution management unit 88 learns the user environment message and the topology change according to the user request, and dynamically updates the virtual group routing table 85.

The virtual group identifying section 87 checks a pair of client address 1 and client address 2 which are the destination and the source of the packet against the virtual group configuration table, and identifies a virtual group including both client addresses. The virtual group identification unit 87 performs dynamic automatic configuration management for terminal movement. As a result of the virtual group identification with respect to the movement of the terminal, when the client address matches but the port is different, a port change message is output, and the intranet virtual group learning / identification unit 90 updates the virtual group registration table to enable dynamic Perform automatic configuration management.

The client address and the priority for each virtual group can be set in the virtual group registration / routing table of each group inside the switch as shown in FIG. 10A, and the virtual group control unit 91 According to the priority, the bandwidth of each traffic type of unicast, multicast, and broadcast is allocated on a group basis. Branch line switch 65 constituting branch line concentrator unit 14
Of the output access control unit 93 to which the packet has been instructed by the scheduling control of the virtual group control unit 91.
a. The forwarding unit 92 includes processing functions of a transmission plan 92a, a connection control 92b, a unicast transmission process 92c, and a multicast segment switch 92d.

The connection ports of each virtual group, that is, the input ports 94a of the input access control unit 94 of the branch line switch 14, are distributed in the distributed network service devices 11 distributed in the network.
Further, in a configuration in which the virtual group registration table 86 and the virtual group routing table 85 are distributed in the distributed network service equipment 11, the virtual group identification unit 87 of each switch uses the input port 94a... 86, and detects a topology change such as a terminal movement, and the virtual group registration table 8
6 and an intranet virtual group learning / identification unit 90 for automatically updating the virtual group routing table 85, and a virtual group distribution management unit 88 of each distributed network service equipment 11.
As a virtual group agent, the virtual group registration table 86 and the virtual group routing table 85 distributed to each switch are dynamically created while cooperating with each other based on the detection of a topology change such as the movement of the terminal and the movement of the switch. , A virtual group is shared by a plurality of distributed network service devices 11 in the network.

Originally, it is also possible to provide a virtual group server that substitutes the virtual group agent distributed to each distributed network service device 11 for each virtual group or for a group of virtual groups. The virtual group server manages the state of the agents, mediates communication between the agents, and dynamically manages the virtual group registration table 86 and the virtual group routing table 85 in cooperation with each other as an agent function of the VLAN switch. The virtual group registration table 86, the client definition table (shown in FIG. 10 (b)) 103, and the virtual group routing table 85, which are updated and managed in the virtual group server, are cached in each of the distributed VLAN switches. The change information in the above table is distributed to each distributed network service device 11.

The branch line concentrator switch 14 of the distributed network service equipment 11 connected to the floor trunk line 3 or the floor branch line 7 performs packet switching, temporarily stores the packet in the packet buffer 95a of the buffer memory 95, and forwards the packet through the packet bus 96 to the forwarding section. 92. The buffer management unit 95a stores the packet pointer in the buffer pointer queuing table 97.
The packet pointer is sent to the virtual group-based queuing 97a, the broadcast queuing 97b, and the unknown group queuing 97c.

The feature of the distributed network service equipment 11 of this embodiment is that the branch equipment local controller 98 constituting the local controller 66 of the branch equipment control unit 13 controls the building equipment, and the branch equipment local controller 98 and the LAN are connected and integrated into a virtual group by a branch line equipment control VLAN connection proxy 99, and the proxy conversion table 100 converts the protocol between the equipment system and the LAN. Also, the facility management proxy agent 101 bridges the local management agent 67 of the monitoring unit 12 and the branch line facility local controller 98 to monitor the control status from the local console connected to the console control unit 67a, and from the center node 5.

2. Description of the Related Art In a corporate network, a centralized network mainly connecting a group of host computers having a database server, an application server, and a communication control function to a terminal for online transaction processing is mainly used for financial services. It was used as a network for institutional accounting or corporate business. In addition, in an information network using a personal computer (hereinafter, referred to as a PC) as a terminal and a LAN connected to a host computer based on the TCP / IP protocol, a client / centralized server network is typical and almost large. Some employees have begun to connect their personal computers, PCs, to the network.

Further, an OS of a workstation (hereinafter referred to as WS) server or a PC server supports online transaction processing and distributed database functions, and is replaced with a host computer as an enterprise server, and an application server of packaged business software. The server machine operates as a database server, multiple servers are integrated in the network, and a distributed server / client type network that performs enterprise-level or global network computing that replaces the conventional host computer is written. It has become popular with the sizing catchphrase.

[0004] In addition, global network computing, which can be seen in derivatives that speed up decision making by making full use of servers distributed on a global scale, is being combined with Internet technology and database replication technology to enable global business activities. Supporting. Intranet and Internet as intra-company networks, WW distributed over networks
The W (World Wide Web) server and the WWW browser of the desktop are rapidly spreading. In particular, a database connected to the WWW server can be used for image,
Since multimedia such as data and voice can be easily accessed as an object in an integrated GUI environment,
The demand for this WWW multimedia network is growing rapidly.

[0005] The computer is easy to use and personalized by the operation system and the WWW technology excellent in GUI, and all the employees are connected to the network to share information, transmit the information immediately, and improve the work efficiency. The business utilization of information and communication technology is progressing because decisions can be made quickly and intellectual productivity is increased, and companies or company models are becoming network-type distributed forms. In addition, information and communication networking technologies, such as networked virtual companies, support global business activities. In this way, network and information and communication technologies are required to have scalability and innovation that can respond quickly to changes in corporate activities more than before, and at the same time, all employees working in offices and other offices need to use the network. High speed and high performance are required in addition to performance, maintainability and economy.

Further, in order to improve intellectual production in offices, in addition to providing amenities (comfortable living environment) by building equipment such as air conditioning and sanitary equipment, lighting equipment, disaster prevention equipment, etc., information and communication technology was used. Intelligent network service functions are required. With the spread of networks and technological innovation, the bandwidth and speed of networks have increased, and the development of higher performance digital information communication technology, network equipment and computing equipment has progressed, and the life of network equipment itself has been shortened. Cycle times have also been shortened, more advanced new products with new features added in the short run, and older products are becoming obsolete. On the other hand, competition between companies and innovation in business activities require that new network equipment corresponding to the latest technological innovation be upgraded or expanded in a short time. For this reason, it is important to economically provide a migration path for gradually introducing a network and expanding devices, to enhance network security, and to provide intelligent network services.

As for multimedia transmission over the Internet and intranets, an RSVP (Resource Re-SerVation Protocol) that preferentially passes stream-type one-way data traffic of telephones and video conferences based on a connectionless IP protocol is known. Peer-to-peer networks such as teleconferencing systems based on Internet-level IP multicast have also been developed. RSVP itself is not a routing protocol, but works with unicast and multicast routing protocols, such as the Internet Control Protocol, which occupies TCP over IP. The receiving side issues a request for guaranteeing transmission quality (hereinafter referred to as QoS). On the node routers and hosts,
The packet classifier determines the route and QoS of the incoming packet, the packet scheduler makes a forwarding decision on a per-packet basis, and the admission control determines whether there are enough resources to support the requested QoS. Decision and policy control determine whether the user is authorized to use the resource.
RSVP transmits and manipulates QoS control parameters as opaque data. RSVP is designed to be extensible to multicast groups with very large members, groups, and tree topologies by means of router "soft states" (using software state transitions).

On the other hand, connection-oriented AT

In other words, the network center collects the servers of the corporate level and network equipment important for network management, the telephone exchange is installed in the switching room, the disaster prevention system and the central monitoring panel of the BA are installed in the central monitoring room of the building. Management has been centralized. Information communication equipment such as a floor concentrator for controlling information communication terminals for each floor, a BA monitoring and control device, and a sub-central device for electric equipment are provided in a wiring closet of each floor, a floor terminal board (floor IDF). ), And is generally mounted in a 19-inch rack, from which a star-type wiring is carried out to the outlet of each floor by a preceding wiring system.

[0010] The wiring of the machine room subsystems from the network center, the switching room, and the central monitoring room are collected as a main line by a main terminal board (hereinafter referred to as MDF), and the floor ID of the wiring closet of each floor is obtained from the MDF.
A trunk wiring sub-system as a backbone to F is configured, and wiring from the floor IDF to terminals or outlets in the floor configures a branch wiring sub-system. Ideally, a star-shaped wiring from the terminal board (IDF) to the outlet of the wall or floor with four pairs of twisted pair wires is used in the shortest distance. The information lines of the trunk wiring subsystem are stored in the EPS together with the power distribution system extending straight from the bottom floor to the top floor of the building. Since the room on each floor where the EPS passes is the earring closet, the wiring closet and the electric shift (EPS) are treated as the same here.

On a relatively large floor, an indoor terminal board (hereinafter referred to as an indoor ID) is mounted on a work group or a wall surface of a room.
F), and a plurality of twisted pair wires using a multi-pair cable are wired in units of the indoor IDF from the floor IDF of the wiring closet to the indoor IDF of the work group. Functionally, the wiring from the floor IDF to the indoor IDF has a form in which a wiring closet is dispersed on the floor, and is referred to as a floor main system wiring subsystem here. In some cases, an indoor concentrator that controls information communication terminals for each room is provided on the floor IDF. In a room, an information terminal device such as a PC can be laid out in an island structure according to the arrangement of desks. Therefore, there is a zone wiring system in which this island is called a zone and a zone box is installed on the floor. A fixed floor wiring is used from the floor IDF or the indoor IDF to the zone wiring box, and a flexible desk wiring system is provided from the zone wiring box to the deskside outlet.

In the floor wiring, there is an access floor in which power wiring to be supplied to an information terminal such as a PC and telephone / LAN information wiring are combined to provide a wiring storage under the floor and a storage space for a wiring box. And L
In the AN wiring, there are a type in which only a passive connector is incorporated in a zone wiring box and a type in which a repeater HUB having several active ports is incorporated as a zone concentrator. Deskside information outlets include a type in which only a passive modular connector is incorporated and an type in which a table tap type repeater HUB having several active ports is incorporated as a deskside concentrator. As a LAN access method used by a terminal, a collision detection type Ethernet (CSMA /
However, with the spread of LANs and the increase in the number of terminals, the advance wiring system using twisted pair wires, which has been used for telephone wiring in the United States, has recently become an IDF crossover. Utilizing the management function of wiring change by batch panel. Ethernet is 10BA with 10Mb / s transmission speed of twisted pair wire.
The SET system has become popular with desktops. The floor wiring of the twisted pair wire is collected in a floor concentrator (floor concentrator) installed in the wiring closet, and the floor concentrator has a function of reproducing and repeating a signal (repeater), so that a higher-speed trunk line L is provided.
It has a bridge / router function to connect to an AN and to segment network traffic. The network center is equipped with a main router that connects to the external Internet, an exchange that connects to the telephone line, a host computer, a file server, and a center concentrator that connects to a high-speed main LAN. I was

The center wiring device and the floor concentrator are mounted on a so-called 19-inch rack, and are available in forms such as a sharn type, a box type, and a stack type. They are interconnected by multi-vendors depending on the communication protocol. In recent years, the speed of 100Mb / s1Gb / s of twisted-pair Ethernet has been increasing,
The transmission distance is 50 to 100 m with unsaturated twisted pair wire (UTP) of CAT5 grade.
In the advanced wiring system, for the time being, even if the transmission speed of 10 Mb / s is almost the case, C
Use AT5 unsilded twisted pair wire,
The optical fiber wiring that can be transmitted over longer distances and at higher speeds and that is fixed to a wall or the like and is flame-retardant is used in the part.

In order to increase the traffic throughput and keep the transmission delay time short as the number of terminals increases and the bandwidth used by each terminal increases, in addition to increasing the transmission speed of the individual wiring, the floor concentrator It has become necessary to improve the line processing capacity of the device. An Ethernet switching type controller chip utilizing the high-speed data processing capability of a semiconductor processor has been commercialized, and a switching HUB capable of simultaneously and independently communicating at a transmission rate of 10 Mb / s and 100 Mb / s in a wire-laying device has been commercialized. Now used. These Ethernet switching ports are
Each port is connected to a specific segment in the concentrator
When filtering is performed based on the AC address, it is called a port switch or a configuration switch. When filtering is performed on an arbitrary segment for each port based on a MAC address, it is simply called a LAN switch. Each of them is called a layer 2 LAN switch. In the server / client type network, the connection to the server and the connection to the backbone have been accelerated, so the connection to the server and the backbone is connected by a 100 Mb / s big pipe, and the connection to the other ports is 10 Mb / s. There is an Ethernet switching HUB having a function of appropriately selecting a transmission speed of a port to be set to s according to traffic. Also, whether the terminal connected to each port is 10 Mb / s
There is an Ethernet switching HUB having a function of automatically recognizing whether it is 0 Mb / s. Even if a repeater HUB having a transmission speed of 10 Mb / s or 100 Mb / s is used for a deskside concentrator or a zone concentrator to which one to several terminals are connected, there is almost no collision, and the repeater HU
The area connected to B and bridged by the switch port is called a micro segment.

[0015] Since most of the traffic is concentrated on the backbone (trunk line) of the network and server connection, scalability of high speed is required, and the server connection is 100 Mb.
s to 1 Gb / s Ethernet. In the backbone, the center concentrator has 100M
When a b / s LAN switch is installed and a LAN switch with a 100 Mb / s interface is installed on the floor concentrator, a frame riser type backbone is used, and further scalability and transmission quality guarantee (QoS) are required. A cell riser type backbone is used in which an ATM switch of an ATM system is installed in a center concentrator and a LAN switch with an ATM interface is installed in a floor concentrator.

Conventionally, the FDDI method is used for the trunk LAN, a main router with an FDDI interface connected to the outside is installed in the center concentrator, and the FDDI-Ethernet bridge router is used for the floor concentrator. However, with the spread of the layer 2 LAN switch, a main router and a layer 2 LAN switch connected to the outside were installed in the center concentrator, and the layer 2 LAN switch was installed in the floor concentrator. Installation, the backbone is a single subnet flat for the routing protocol, the LAN switch segment is a broadcast domain and an independent LAN is configured, and the traffic between the segments is There is a method to pass an in-router.
Furthermore, the segment is registered in a table as a group of MAC addresses, an implicit VLAN forming an implicit virtual LAN segment, and an explicit forming an explicit virtual LAN segment inserting a tag that can be identified for each group into a packet. There is a VLAN.
In a layer 2 VLAN using such a layer 2 LAN switch, a segment independent of the physical wiring can be arbitrarily set across the floor concentrators using the filtering function of the switch, and can be set according to the corporate organization or the work group. Segmentation is possible. When the layer 2 LAN switch is configured by ATM LAN emulation, it is a virtual LAN configured on the VPI / VCI connection, but the LAN emulation does not guarantee the transmission quality (QoS).

However, when a flat subnet is divided into a plurality of Layer 2 subnets, all broadcasts are concentrated on the main router, and traffic between segments is also concentrated on the main router. The failure of the main router could cause a bottleneck, or a one-point failure point, causing the entire network to shut down.

Therefore, when accessing a server centrally managed in a network center or configuring a plurality of overlapping segments across segments, traffic to be communicated across segments of the layer 2 LAN switch increases. As a floor concentrator, a switch called a layer 3 LAN switch has been developed which is filtered based on a routing protocol address or a protocol type. When a layer 3 switch is used, a layer 3 virtual network segment is formed by an address of a logically defined protocol without depending on a physical wiring such as a MAC address or a port, and may be called a virtual subnet. The Layer 3 LAN switch has a router function, so that traffic across the Layer 2 subnets can be switched directly without passing through the main router. Can be provided to enhance security. Layer 3 LA
N switches M over ATM LAN emulation
In the case of the configuration using the POA method, since the standardization has not been completed yet, there is a case where the vendor implements it according to its own specification, and a limited transmission quality guarantee (QoS) is also made. A backbone LAN system that uses an I-PNNI system for routing between ATM switches and uses a layer 3 LAN switch for an edge LAN switch has also been developed.

The IP switch system or the tag switch system, which has recently attracted attention, is a layer 3 LAN switch on an ATM switch, which has been independently developed by the LAN vendor and proposed for standardization. In this way, in response to an increase in backbone traffic, layer 2 virtual LA integrating routing technology and switching technology
Higher-end systems such as center concentrators and floor concentrators for N and layer 3 virtual networks are being developed.

The backbone switch 58 is provided with redundancy by combining well-known technologies such as Layer 2 and Layer 3 switching or ATM switch, and provides the backbone with information that requires high reliability and immediacy such as BA and disaster prevention, and other information. Supports data communication and multiplex transmission functions. For this purpose, the QoS function of the ATM switch is promising. As shown in the figure, a center management console 52a for network management, BA management, and disaster prevention / security management is connected to the monitoring unit 52.

On the other hand, the local node 1a (or 1) sets up a multicast group such as an electronic conference using multimedia in the local network service server 10 or creates a virtual common information space different from the physical arrangement.

FIG. 8 shows a specific configuration of the distributed network service equipment 11 used in this embodiment. The ATM is connected to the backbone wiring 4 through the backbone connection ATM interface 81 including the backbone buffer memory 80 constituting the backbone switch 62 of the backbone connection unit 15.
In the intranet routing / bridge protocol processing unit 70 for constructing the router bridge 64, the route calculation learning / filtering 83 of the layer 3 and the address learning / filtering 84 of the layer 2 are performed, and the virtual routing table 63 of the trunk connection unit 15 is performed. Is created and queried in the virtual group routing table 85. Once the address has been learned, it operates in cut-through, bypassing the intranet routing / bridge protocol processing unit 70 . In this embodiment conforming to the standard by the ATM Forum, in the same manner as the intranet routing / bridge protocol processing unit 82 of the integrated network service device 51 described later, the ATM is converted to a LAN packet by LAN emulation, and the MPOA of the upper layer is further converted. Function of processing a virtual router according to the above, 1-PNN1, IP connection (RFC157
A function capable of supporting a standard protocol such as 7) is provided in the intranet routing / bridge protocol processing unit 82.

The virtual group registration table 86 and the virtual routing table 85 of the distributed network service equipment 11 can set the client address and virtual group ID of the virtual group, and the destination virtual group ID is not the local site virtual group ID. In such a case, a packet local to the main router of the WAN connection unit 55 of the integrated network service device 51 is filtered so as to forward the packet from the distributed network service device 11 to the main router. If the destination virtual group ID is the local site virtual group ID, unicast to the port of the destination client address.

When addition / movement / change of a node is detected in the virtual group registration table 86 and the routing table 85 of the distributed network service equipment 11, the update information of the virtual group registration table 86 and the routing table 85 is given higher priority. By multicasting to each distributed network service device 11 at a time, the distributed network service device 11 performs the distributed processing of the routing calculation of the local virtual group. The route calculation processors of the distributed network service devices 11 share the intranet routing table of the local virtual group with each other, and the parallel control kernel units (not shown) of each distributed network service device 11 share the same while synchronizing with each other. The intranet routing table information in the memory is exchanged, and the optimal virtual group routing table 85 is sequentially maintained and managed.

In the virtual group identification unit 87, the client address 1 and the client address 2 are encoded by one hash function and collated with the virtual group configuration table similarly hashed. Alternatively, there is no problem of an increase in delay time as compared with the method of adding a tag. That is, M
O which defined AC address as client address
At the second layer level of the SI protocol hierarchy model, a virtual LAN group is added to a terminal that conforms to the traditional standard without adding an extra header or tag to the packet according to the traditional standard. Support.

Further, the virtual group identifying section 87 stores a pair of MAC addresses 1 as the destination and the source of the packet.
And the MAC address 2 is compared with the virtual group configuration table to identify a virtual group to which both MAC addresses are combined. In addition, at the third level of the OSI protocol hierarchy model in which a plurality of network addresses depending on the communication protocol are defined as client addresses, extra headers or tags are added to the packet in accordance with the conventional traditional standards. Without any addition, support virtual network groups for traditional compliant terminals.

Further, the virtual group identifying section 87
Compares a pair of network address 1 and network address 2 which are the destination and source of the packet with the virtual group configuration table, and identifies a virtual group in which both network addresses are combined. In addition, at the application level of the OSI protocol hierarchy model in which the user address or the application address defined by the application software is used as the client address, an extra header or tag is added to the packet in accordance with the traditional standard. Instead, it supports the setting of a virtual custom group in which different media access methods and communication protocols are mixed.

The virtual group identifying section 87 compares a pair of the application address 1 and the application address 2 which are the destination and the source of the packet with the virtual group configuration table, and identifies the virtual group including both application addresses. . Here the virtual group registration / routing table (to the combined 8 5, 8 6 above) in FIG. 10 (a), usually registers the client name to each client address. Different client names can be registered for each virtual LAN group, virtual network group and virtual custom group.
When a group, a virtual network group, and a virtual custom group are respectively defined, a row defining a virtual group and a row defining a virtual network group are included in the virtual group registration / routing table of FIG. And a line defining a virtual custom group. Further, the client definition table 103 (FIG. 10)
(Shown in (b)).

The virtual group identification unit 87 gives the highest priority to the collation of the virtual custom group, collates the virtual network group first, and finally the virtual group. This client name is the name of the switch,
The device type is also registered, as is the identification code of the device type such as a terminal. When the device type is a switch, the virtual group distribution management unit 88 registers the MAC address directly connected to the port of the switch or the switch connection map 89 indicating whether the device is indirectly connected. Together with the virtual group registration table 86 and the switch connection map 89, connection map information of the entire network can be obtained. Since the connection between the adjacent ports is known, the topology can be drawn in a connection relation diagram, and the connection relation diagram is called a map (MAP). If the topology is a tree structure, route search is easy, but if the topology is a mesh, it is necessary to compare the transmission time distances of a plurality of routes. When switches having the same transmission speed are connected in multiple stages, the number of stages is regarded as the distance.

In the virtual group registration / virtual group routing table shown in FIG. 10A, the optimum connection port address is registered as a routing connection port. In other words, in the configuration of the distributed switch, since other switches are cascaded to the ports of each switch, the connection port is optimally connected to the home switch to which the terminal is connected. This is the port name corresponding to the root.
When a port change message is output when the client address matches but the port is different as a result of the virtual group identification for the movement of the terminal, the intranet virtual group learning / identification unit 90 sends the topology change message to the virtual group distribution management unit 88. send. At this time, the virtual group distribution management unit 88 learns the user environment message and the topology change according to the user request, and dynamically updates the virtual group routing table 85.

The virtual group identifying section 87 checks a pair of client address 1 and client address 2 which are the destination and the source of the packet against the virtual group configuration table, and identifies a virtual group including both client addresses. The virtual group identification unit 87 performs dynamic automatic configuration management for terminal movement. As a result of the virtual group identification with respect to the movement of the terminal, when the client address matches but the port is different, a port change message is output, and the intranet virtual group learning / identification unit 90 updates the virtual group registration table to enable dynamic Perform automatic configuration management.

The client address and the priority for each virtual group can be set in the virtual group registration / routing table of each group inside the switch as shown in FIG. 10A, and the virtual group control unit 91 According to the priority, the bandwidth of each traffic type of unicast, multicast, and broadcast is allocated on a group basis. Branch line concentrator units that make up the branch line concentrator unit 14
14 , the forwarding section 92 in the branch switch 65
Transfer the packet to the designated output port 93a of the output access control unit 93 by the scheduling control in the virtual group control unit 91. The forwarding unit 92 includes the transmission plan 92a and the connection control 9
2b, a unicast transmission process 92c, and a multicast segment switch 92d.

The connection ports of each virtual group, that is, the input ports 94a of the input access control unit 94 of the branch line switch 14, are distributed in the distributed network service devices 11 distributed in the network.
Further, in a configuration in which the virtual group registration table 86 and the virtual group routing table 85 are distributed in the distributed network service equipment 11, the virtual group identification unit 87 of each switch uses the input port 94a... 86, and detects a topology change such as a terminal movement, and the virtual group registration table 8
6 and an intranet virtual group learning / identification unit 90 for automatically updating the virtual group routing table 85, and a virtual group distribution management unit 88 of each distributed network service equipment 11.
As a virtual group agent, the virtual group registration table 86 and the virtual group routing table 85 distributed to each switch are dynamically created while cooperating with each other based on the detection of a topology change such as the movement of the terminal and the movement of the switch. , A virtual group is shared by a plurality of distributed network service devices 11 in the network.

Originally, it is also possible to provide a virtual group server that substitutes the virtual group agent distributed to each distributed network service device 11 for each virtual group or for a group of virtual groups. The virtual group server manages the state of the agents, mediates communication between the agents, and dynamically manages the virtual group registration table 86 and the virtual group routing table 85 in cooperation with each other as an agent function of the VLAN switch. The virtual group registration table 86, the client definition table (shown in FIG. 10 (b)) 103, and the virtual group routing table 85, which are updated and managed in the virtual group server, are cached in each of the distributed VLAN switches. The change information in the above table is distributed to each distributed network service device 11.

The branch line concentrator switch 14 of the distributed network service equipment 11 connected to the floor trunk line 3 or the floor branch line 7 performs packet switching, temporarily stores the packet in the packet buffer 95a of the buffer memory 95, and forwards the packet through the packet bus 96 to the forwarding section. 92. The buffer management unit 95 b is a buffer pointer queuing table 97 the packet pointer
The packet pointer is sent to the virtual group-based queuing 97a, the broadcast queuing 97b, and the unknown group queuing 97c.
