Prior to the description of the embodiment of the present invention, the outline of the features of the present invention will be described with reference to FIG.

  As shown in FIG. 1, a network device setting apparatus 1 (corresponding to a network management system described later) according to the present invention includes a network device information storage unit 11, a network device detection unit 12, and a topology detection unit 13 (Ethernet described later). -Ring detection function) and a network device setting unit 14 (corresponding to an Ethernet-ring setting function described later).

The network device setting device according to the present invention detects that the network device forms a ring topology, and generates setting information for setting the network device based on the device information of the network device and the topology information. Therefore, settings suitable for the network configuration can be performed.

(Embodiment 1)
The first embodiment will be described below with reference to the drawings. FIG. 2 shows a configuration of a network system (network device setting system) according to the present embodiment.

  As shown in FIG. 2, the network system includes network devices 101 to 103 constituting a ring network, and a network management system (NMS) 120 connected to the network devices 101 to 103 via a network 130. .

  The network devices 101 to 103 are devices such as a relay device configuring a network such as a switch and a router, and are devices that can configure EPR Ethernet-ring, for example. The network devices 101 to 103 have one or more ports and are connected to other network devices and the network management system 120 to exchange information. The network devices 101 to 103 store one or more identification IDs in the storage means. When the network devices 101 to 103 are newly installed in the network 130, they pass the identification ID to the network management system 120. The network devices 101 to 103 are each physically connected by a network cable to form a ring network (ring topology).

  The identification IDs 111 to 113 are information included in at least one of each of the network devices 101 to 103. When there are a plurality of network devices, it is information that can identify which network device, for example, MAC address, IP address, MEP ID of ETER OAM (IEEE 802.1ag), etc. are applicable.

  The network management system 120 is connected to the network devices 101 to 103, and performs monitoring, control, and the like of management target network devices set in advance. The network management system 120 includes a network device information DB (database) 121, a network device detection function 122, an Ethernet-ring detection function 123, an Ethernet-ring setting function 124, and a topology information DB 125. For example, when the network device detection function 122 determines that the target network devices 101 to 103 are newly installed, the network management system 120 corresponds to the network devices 101 to 103 with respect to the target network devices 101 to 103. Setting is automatically performed based on the network device information 121a to be performed.

  Each unit (each function and each processing unit) of the network management system 120 is configured by hardware, software, or both. Further, each part of the network management system 120 may be realized by a computer having a CPU, a memory, and the like. For example, each unit of the network management system 120 may be realized by executing a network device setting program according to the present embodiment on the CPU.

  In the network device information DB (database) 121, the network device information 121a of the network devices 101 to 103 to be managed is registered. In the network device information 121a, a network device identification ID, network device configuration information, and Ethernet-ring configuration information are associated with each other. For example, the network device information DB 121 is registered in advance by a system administrator or the like. Network device configuration information (also simply referred to as configuration) is, for example, setting information necessary for a network device to perform relaying using Ethernet technology, and includes interface setting information such as identification information about the interface, speed, valid / invalid, Protocols relating to routes, routing tables, route setting information such as FDB (Forwarding DataBase), and the like. The Ethernet-ring configuration information (also simply referred to as configuration) is information necessary for configuring an ERP Ethernet-ring, such as RINGID.

  The network device detection function 122 determines whether the network devices 101 to 103 are newly installed in the network 130 based on the identification IDs 111 to 113 of the network devices 101 to 103 and the network device information 121a registered in the network management system 120. Detect whether or not.

  The Ethernet-ring detection function 123 obtains information on a newly installed network device from the network device detection function 122, and determines whether all or a part of the detected network devices 101 to 103 constitutes an Ethernet-ring. It is a function to detect. For example, the Ethernet-ring detection function 123 detects which network device is connected and how (topology), registers topology information such as connection information 125a in the topology information DB 125, and forms a network device in a loop. Is detected. Note that the topology may be detected as in Patent Document 2 above. Further, the method for detecting the loop is arbitrary.

  The Ethernet-ring setting function 124, when the Ethernet-ring detection function 123 determines that the Ethernet-ring is configured, provides configuration information (network information for the network-ring) to the network device that configures the Ethernet-ring. Based on the connection information 125a in the topology information DB 125 and the RINGID in the device information 121a), the network device is set for Ethernet-ring.

  The topology information DB 125 stores topology information related to the topology detected by the Ethernet-ring detection function 123. The topology information stored in the topology information DB 125 is cable connection information (opposite device identification ID and port information) 125a and the like.

  As described above, in this embodiment, simply by installing the network device, the network management system automatically sets the configuration for the network device. Therefore, it is necessary to register the configuration information in advance on the network management system side. , It can be configured reliably at any time. Conversely, there is no adverse effect even if the installation is first, so the network administrator can select a convenient method. This eliminates the need for close coordination between the administrator and the installer as before application of the present invention, and increases the degree of freedom in network operation. Also, in the present embodiment, network devices are set based on device information including Ethernet-ring configuration information and topology information including connection information, and therefore settings suitable for the network configuration can be performed.

(Embodiment 2)
The second embodiment will be described below with reference to the drawings. In this embodiment, a configuration example using an IP address as an identification ID will be described as a specific example of the first embodiment.

  FIG. 3 shows a configuration of a network system (network device setting system) according to the present embodiment. As in FIG. 2, the network system in FIG. 3 includes network devices 201 to 203 (corresponding to 101 to 103 in FIG. 2) constituting a ring network, and a network management system 220 connected to the network device 203 (in FIG. 2). Equivalent to 120). Note that the network devices 201 to 203 and the network management system 220 may be connected via a network as in FIG.

  Network devices 201 to 203 (hereinafter abbreviated as NE) hold IP addresses as identification IDs 211 to 213 and configurations 241 to 243 set in the NEs 201 to 203, respectively, in internal storage means. . In this example, the NE 202 is a newly installed NE and is in a state where only a minimum configuration is set.

  NE 201 and NE 202 and NE 203, NE 202 and NE 203 are connected by a network cable to form a ring network, and NE 203 and network management system 220 are connected by a network cable.

  The network management system 220 (hereinafter abbreviated as NMS) includes a network device information DB 221, a network device detection function 222, an Ethernet-ring detection function 223, an Ethernet-ring setting function 224, and a topology information DB 225.

  The network device information DB 221 is a database that stores network device information 221a in which an IP address that is an identification ID of an NE, an NE configuration, and a RING ID of a ring that the NE configures are associated with each other. The RINGID is ring identification information for setting the same ID between devices constituting the ERP Ethernet-ring, and the RINGID constitutes the Ethernet-ring.

  The network device detection function 222 periodically sends a ping (response request message) to the IP address of the network device information 221a registered in the network device information DB 221. The NE 201 to 203 responding to the ping is connected by telnet to acquire configuration information of the target NE. The acquired configuration is compared with the configuration of the network device information 221a registered in the network device information DB 221, and if there is a difference, it is determined as a new NE.

  The topology information DB 225 is a database that stores, as Ethernet-ring topology information, connection information 225a in which an IP address, which is an NE identification ID, is associated with an NE port ID. The connection information 225a indicates the connection relationship between NEs. For example, the connection information 225a includes the IP address and port ID of the connection source (left column) and the connection destination (right column) of the opposite connection. ID.

  In the present embodiment, since the NE connection relationship is known from the connection information 225a and the RINGID is known from the network device information 221a, the devices (ports) constituting the same ring are determined based on the connection information 225a and the network device information 221a. Set the same RINGID.

  The operation of the network management system 220 according to the present embodiment will be described using the flowchart of FIG.

  First, in the start state (S301), the network device information 221a including the IP address of the NE 202 exists only in the network device information DB 221 of the NMS 220, and the NE 202 is not installed in the network.

  The network device detection function 222 of the NMS 220 periodically sends a ping (ICMP ECHO request) to the IP addresses included in the three network device information 221a registered in the network device information DB 221 to perform NE 201-203. Confirm that is installed. The network device detection function 222 transmits a ping to the IP address of the NE 202, but since the NE 202 does not exist, a response to the ping is not received from the NE 202, and the ping always times out. Thereby, the network device detection function 222 detects that the NE 202 is not installed.

  Subsequently, the NE 202 is newly installed and added to the network (S302). Then, the added NE 202 replies (ICMP ECHO reply) to the ping transmitted by the NMS 220 (S303). Accordingly, since the network device detection function 222 receives a ping reply from the NE 202, the ping timeout for the NE 202 that has occurred is eliminated (S304). Thereby, the network device detection function 222 detects that the NE 202 is installed in the network.

  Subsequently, the network device detection function 222 determines whether the configuration of the NE 202 is registered in the network device information 221a of the network device information DB 221 when the ping timeout for the NE 202 is resolved (S305). . When the NE 202 configuration is not registered in the network device information 221a, the network device detection function 222 terminates the processing without doing anything because the configuration setting is unnecessary (S306), and when the configuration is registered. The process proceeds to the next process.

  As the next processing, the network device detection function 222 acquires the configuration 242 of the NE 202 via the telnet by connecting to the NE 202 with the telnet and transmitting a telnet command (S307).

  Subsequently, the network device detection function 222 compares the configuration of the network device information 221a registered in the network device information DB 221 corresponding to the NE 202 with the configuration 242 acquired from the NE 202 (S308). If there is no difference between the comparison result of the configuration of the network device information DB 221 and the configuration 242 of the NE 202, the network device detection function 222 ends the processing without doing anything because the configuration setting is unnecessary (S306).

  Subsequently, when the network device detection function 222 determines that there is a difference as a result of the comparison between the configuration of the network device information DB 221 and the configuration 242 of the NE 202, the Ethernet-ring detection function 223 creates topology information and adds Ethernet to the network configuration. It is determined whether or not a -ring exists (S309). For example, the Ethernet-ring detection function 223 detects the ring topology by registering the topology information including the connection information 225a in the topology information DB 225 by detecting the connection relation of the NE. If the Ethernet-ring detection function 223 determines that there is no Ethernet-ring, the configuration setting is unnecessary, and the process ends without doing anything (S306).

  Subsequently, when the Ethernet-ring detection function 223 determines that Ethernet-ring exists in the network configuration, the Ethernet-ring setting function 224 uses the connection information 225a (identification ID and port information) that is Ethernet-ring topology information. ) And network device information 221a (identification ID and RINGID) are combined with the identification ID as a key to create setting information (S310). In other words, the Ethernet-ring setting function 224 extracts the connection information 225a constituting the Ethernet-ring from the topology information DB 225, and associates all IP addresses, port IDs, and RINGIDs based on the connection information 225a and the network device information 221a. To generate setting information (port setting information).

  Subsequently, the Ethernet-ring setting function 224 performs setting for each NE (port) constituting the Ethernet-ring based on the generated setting information (S311), and ends the process (S312). The Ethernet-ring setting function 224 sets a RINGID to each port of the NEs 201 to 203 via telnet. Further, the Ethernet-ring setting function 224 sets the configuration of the network device information 221a in the added NE 202.

  As described above, in this embodiment, an IP address is used as an ID for identifying a network device, and network device information and topology information are associated with each other using the IP address as a key. Accordingly, even when an ERP Ethernet-ring is configured with a layer 3 switch or a router, each network device can be set appropriately. Also, by periodically sending a ping from the network management system 220, it is possible to reliably detect a new installation of a network device. Also, if the detected network device has a configuration that is different from the configuration registered in the network management system, it is determined as a newly installed network device, and the configuration is set, so it is determined that the installation is accurate. This can also prevent useless configuration settings.

(Embodiment 3)
The third embodiment will be described below with reference to the drawings. In this embodiment, a configuration example using a MAC address as an identification ID will be described as a specific example of the first embodiment.

  That is, in the second embodiment, the IP address is used for the identification ID, but in this embodiment, the MAC address is used. In the first embodiment, pings are periodically performed from the NMS side. However, in this embodiment, an Ethernet OAM (IEEE 802.1ag) multicast LB (Loopback) frame (notification message) is transmitted from the NE side during installation. ). When the NMS receives this multicast LB frame, a new NE is detected.

  FIG. 5 shows a configuration of a network system (network device setting system) according to the present embodiment. As in FIG. 2, the network system in FIG. 5 includes network devices 401 to 403 (corresponding to 101 to 103 in FIG. 2) constituting a ring network, and a network management system 420 (in FIG. 2) connected to the network device 403. Equivalent to 120).

  The NEs 401 to 403 respectively hold MAC addresses as identification IDs 411 to 413 and configurations 441 to 443 set in the NEs 401 to 403 in internal storage means. Further, the NEs 401 to 403 have Ehter OAM functions 451 to 453. The Ehter OAM function transmits and receives OAM frames such as LB frames. In this example, the NE 402 is a newly installed NE and is in a state where only a minimum configuration is set.

  NE 401 and NE 402 and NE 403, NE 402 and NE 403 are connected by a network cable to form a ring network, and NE 403 and NMS 420 are connected by a network cable.

  The NMS 420 includes a network device information DB 421, a network device detection function 422, an Ethernet-ring detection function 423, an Ethernet-ring setting function 424, and a topology information DB 425.

  The network device information DB 421 is a database that stores network device information 421a in which the MAC address, which is the NE identification ID, the NE configuration, and the RING ID of the ring formed by the NE are associated with each other. In addition, a flag indicating whether the NE of the registered network device information 421a is a newly installed device is also provided.

  The network device detection function 422 detects that an NE has been added to the network by receiving a multicast LB frame from the NE. Further, the network device detection function 422 can acquire the configuration of the NE that has transmitted the LB frame. For example, it may be acquired via Ether OAM or via telnet if an IP address is set. Note that the configuration may be acquired as in Patent Document 1 above. The network device detection function 422 may determine that the network device information 421a is a new NE based on the presence or absence of the flag (“◯”) in the network device information 421a. Similarly to the second embodiment, the acquired configuration and network device information 421a If there is a difference, it may be determined as a new NE.

  The topology information DB 425 is a database that stores, as Ethernet-ring topology information, connection information 425a in which a MAC address, which is a NE identification ID, and a NE port ID (for example, a physical port) are associated with each other. The connection information 425a indicates the connection relationship between NEs. For example, the connection information 425a includes the MAC address and port ID of the connection source (left column) and the MAC address and port of the connection destination (right column) to be connected oppositely. ID.

  In the present embodiment, the NE connection relationship is known from the connection information 425a, and the RINGID is known from the network device information 421a. Therefore, based on the connection information 425a and the network device information 421a, the devices (ports) constituting the same ring are used. Set the same RINGID.

  The operation of the network management system 420 according to the present embodiment will be described using the flowchart of FIG.

  First, in the start state (S501), the network device information 421a including the MAC address of the NE 402 exists only in the network device information DB 421 of the NMS 420, and the NE 402 is not installed in the network.

  Subsequently, when the NE 402 is installed in the network (S502), the NE 402 spontaneously transmits a multicast LB frame of Ether OAM (S503). For example, the NE stores a multicast address of a network including the NE and the NMS, and transmits an LB frame with the multicast address as a destination. The network device detection function 422 of the NMS 420 receives the LB frame destined for the multicast address (S504), and detects that the NE 402 is installed in the network.

  Subsequently, the network device detection function 422 determines whether the network device information 421a of the NE 402 is registered in the network device information DB 421 when the LB frame is received from the NE 402 (S505). When the transmission source MAC address of the LB frame is not registered in the network device information DB 421, the network device detection function 422 ends the processing without doing anything because the configuration setting is unnecessary (S506). If registered, the process proceeds to the next process.

  As the next process, the network device detection function 422 determines the presence or absence of flag information associated with the transmission source MAC address of the LB frame for the network device information 421a corresponding to the NE 402 (S507). If the network device information 421a does not include a flag (“◯”), the network device detection function 422 does not need to set a configuration and ends the processing without doing anything (S506).

  Subsequently, when the network device detection function 422 has a flag (“◯”) in the network device information 421a (is standing), the Ethernet-ring detection function 423 creates topology information and sets the network configuration. It is determined whether there is an Ethernet-ring (S508). For example, the Ethernet-ring detection function 423 determines topology by registering topology information including the connection information 425a in the topology information DB 425 by detecting the connection relation of the NE. If the Ethernet-ring detection function 423 determines that there is no Ethernet-ring, the configuration setting is unnecessary, and the process ends without doing anything (S506).

  Subsequently, when the Ethernet-ring detection function 423 determines that Ethernet-ring exists in the network configuration, the Ethernet-ring setting function 424 determines the connection information 425a (identification ID and port information) that is Ethernet-ring topology information. ) And network device information 421a (identification ID and RINGID) are combined with the identification ID as a key to create setting information (S509). That is, the Ethernet-ring setting function 424 extracts the connection information 425a constituting the Ethernet-ring from the topology information DB 425, and associates all the MAC addresses, port IDs, and RINGIDs based on the connection information 425a and the network device information 421a. To generate setting information (port setting information).

  Subsequently, the Ethernet-ring setting function 424 sets each NE (port) that configures the Ethernet-ring based on the generated setting information (S510), and ends the process (S511). For example, the Ethernet-ring setting function 424 sets the RINGID to each port of the NEs 401 to 403 by setting via the Ethernet OAM, or setting via the telnet if an IP address is set. In addition, the Ethernet-ring setting function 424 sets the configuration of the network device information 421a in the added NE 402. Note that when the configuration of the network device information 421a is set, since it is not a newly added NE, the flag of the network device information 421a may be deleted.

  As described above, in this embodiment, a MAC address is used as an identification ID for a network device, and network device information and topology information are associated with each other using the MAC address as a key. Thereby, even when configuring ERP Ethernet-ring with a layer 2 switch or the like, each network device can be appropriately set. Further, by transmitting an OAM frame from the network device at the time of installation, it is possible to reliably detect a new installation of the network device. Further, since a newly installed network device is determined based on the flag of the network device information and a configuration is set, it can be determined accurately and easily that a new installation is established, and useless configuration setting can be prevented.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, in the above example, RINGID is set as Ethernet-ring configuration information, but other parameters necessary for configuring Ethernet-ring, such as a ring node ID for identifying a node in the ring, are set. Also good. In the above example, the setting is performed using the telnet or the OAM frame. However, a protocol for setting the device such as SNMP (Simple Network Management Protocol) may be used.
