In order to facilitate understanding of the present application, a description will be given below of a related art to which embodiments of the present invention relate.
Three-tier network architecture
The three-tier network architecture includes three levels: the core layer is a high-speed switching backbone of the network and plays a vital role in the communication of the whole network. The core layer mainly has the function of realizing the optimized transmission among backbone networks and has the characteristics of reliability, high efficiency, redundancy, fault tolerance, manageability, adaptability, low time delay and the like.
The convergence layer is the 'medium' between the access layer and the core layer, namely, the convergence is performed before the workstation accesses the core layer, so as to reduce the load of the core layer equipment. The convergence layer has a plurality of functions such as policy enforcement, security, workgroup access, routing between Virtual Local Area Networks (VLANs), source address or destination address filtering, and the like. The convergence layer generally employs switches supporting three-layer switching technology and VLANs to achieve the purpose of network isolation and segmentation.
The access layer is used for providing workstation access for the local network segment. The access stratum may allow end users to connect to the network, primarily to address the need for inter-access between adjacent users, and to provide sufficient bandwidth for such access. The access layer also has user management functions, such as address authentication, user authentication, billing management, etc., and information collection functions, such as collecting the user's IP address, Media Access Control (MAC) address, access log, etc. The access layer can utilize transmission media such as optical fibers, twisted-pair wires, coaxial cables, wireless access technologies and the like to realize connection with users and distribute services and bandwidths.
Network topology
A Network Topology (NT) architecture refers to the physical layout of the various devices interconnected by a transmission medium, particularly where computers are distributed and how cables connect them. The network topology structure can reflect the structural relationship of the network, and the difference of the network topology structure has important influence on the performance, reliability, network construction cost and the like of the network, so the design of the network topology structure has very important position in the network construction. Common network topologies include bus, star, ring, and mesh topologies.
The bus topology uses a single transmission line as a transmission medium, and all stations are connected to the transmission line, which is called a bus. In a bus-type topology, data sent by any one station needs to be transmitted over the bus, and the data can be received by all stations on the bus. The bus topology is suitable for the field of information management systems and office automation systems.
The star topology comprises a central node, other nodes are connected with the central node to form a radiation-shaped structure, and communication of each node in the star topology needs to be forwarded through the central node. The star topology is suitable for file server and workstation local area networks.
In the loop, the data of each node is transmitted according to one direction, and after the data is sent by the sending node, the data returns to the sending node after being transmitted for one circle along the loop and is deleted by the sending node. The ring topology is suitable for use in a microcomputer LAN, an information processing system, and a factory automation system.
The connections between the nodes in the mesh topology are arbitrary, and each node may connect other nodes through a plurality of lines, so that a plurality of transmission paths exist between the nodes. When the nodes in the network topology transmit data, the nodes can flexibly select idle lines or avoid fault lines. Mesh topologies are suitable for large wide area networks.
As shown in fig. 1, an embodiment of the present invention provides a network topology schematic diagram, which includes a core layer, a convergence layer, and an access layer.
Wherein the core layer comprises core equipment for optimizing transmission between backbone networks; the convergence layer comprises a plurality of convergence devices (such as a first convergence device and a second convergence device) and is used for providing data convergence, transmission, management and distribution services for the access devices of the access layer; the access stratum includes a plurality of access devices (e.g., a first access device, a second access device, and a third access device) for providing network access services to the terminal.
It should be noted that the core device, the aggregation device, and the access device may all be switches, and the difference is that the switch in the access layer is used to connect the terminal, the switch in the aggregation layer is used to aggregate the data reported by the switch in the access layer, and the switch in the core layer is used to process the data reported by the switch in the aggregation layer. Because the functions of the core layer, the convergence layer and the access layer are different, the processed data are also different, and therefore the switches of the core layer, the convergence layer and the access layer are also different. Of course, the core device, the aggregation device, and the access device are all switches only for example, and the core device, the aggregation device, and the access device may also be other network devices, such as an access device, a router, a multiplexer, a modem, and the like, which is not limited in this embodiment of the present invention.
It should be noted that the schematic diagram of the network architecture shown in fig. 1 is only an example, and in reality, the network architecture may also be other structures, and the network architecture may further include other aggregation devices, access devices, and terminals, which is not limited to the embodiment of the present invention. Fig. 1 only shows a schematic diagram of a first access device connecting a terminal under a first aggregation device, in practice, a second aggregation device may also be connected to multiple access devices, and a second access device and a third access device may also be connected to multiple terminals, and fig. 1 does not show connection devices under the second aggregation device, the second access device, and the third access device. The terminal may be a mobile phone, a computer, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a smart phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite radio device, a wireless modem card, a Set Top Box (STB), a Customer Premises Equipment (CPE), and/or other devices for communicating over a wireless system.
Because the access layer can generally adopt a ring topology structure to deploy the access device, the embodiment of the invention provides an access device configuration method aiming at the ring topology structure of the access layer, which is used for improving the construction efficiency of the access layer. An embodiment of the present invention provides an access device configuration method based on a ring topology of an access stratum, as shown in fig. 2, including:
s101, a network management system receives a first message sent by a gateway network element.
Wherein the first message includes a first address of the first access device.
Specifically, the Gateway Network Element (GNE) may be an aggregation device. The gateway network element may receive a second message sent by the first access device, where the second message may include information such as a first access device identifier, a first address, a manufacturer, and a device model of the first access device. The first access device identifier may be a Network Element Identity (NEID) of the first access device, and the first address may be a NEIP of the first access device.
After receiving the second message, the gateway network element may generate a NEIP route, and send the first message to the network management system according to the NEIP route. The NEIP route here is used to indicate the IP address of the next hop of the gateway network element.
It should be noted that the first message may include not only the first address of the first access device, but also information such as the first access device identifier, the manufacturer, and the device model of the first access device. The first message may be a simple network management protocol Trap (SNMP Trap) message, and the gateway network element may report information to the network management system through the SNMP Trap message. The SNMP Trap is actually a mechanism for a managed device to actively send a message to a network management system, and the managed device may be a gateway network element.
S102, the network management system determines the home network of the first access device according to the second address.
Wherein the second address is an address of a gateway network element.
In particular, the network management system may parse the second message, thereby determining a source IP address of the second message, i.e. determining the second address. The network management system can also determine the home network of the gateway network element by querying the home network of the second address, where the home network refers to the home location of the gateway network element, and if the second address of the gateway network element is 111.192.0.0-111.192.14.255, the network management system can determine that the home location of the gateway network element is in beijing city; if the second address of the gateway network element is between 42.236.0.0-42.236.3.255, the network management system can determine that the home location of the gateway network element is zheng city, hannan province. Because the access equipment of the access gateway network element and the gateway network element belong to the same home network, after the network management system determines the home network of the gateway network element, the home network of the access equipment accessed by the network management system can be determined.
It should be noted that the process of determining, by the network management system, the home location of the first access device according to the second address of the gateway network element is a conventional technical means in the art, and this is not described in detail herein in the embodiment of the present invention, and a method for determining the home location of the second address may be selected by a person skilled in the art according to needs.
S103, the network management system determines configuration parameters of the first access device according to the first address and the network topology of the home network, and sends a configuration file to the first access device.
The configuration parameters comprise port connection information and a target address, wherein the port connection information is used for indicating the port connection relation of the first access equipment, and the target address is used for indicating the port address of the first access equipment; the configuration file includes configuration parameters.
Specifically, since the network management system stores the network topology structures of the respective cities in advance, and the network topology structures have been designed with the network devices to which the respective nodes access in advance, including the device information of the respective network devices, the network management system can match the device information of the first access device with the device information of the network devices of the respective nodes of the access layer in the network topology structure after receiving the device information (such as the first address, the first access device identifier, the manufacturer, and the like) of the first access device, thereby determining the position of the first access device in the network topology structure.
Because the network topology structure also designs the target address and port connection information of the network device of each node, the network management system can determine the configuration parameters of the first access device according to the device information of the first access device and the pre-designed network topology structure.
Optionally, the network topology includes a target address and a third address of the second access device, as shown in fig. 3, step S103 may include:
and S1031, the network management system determines the mapping relation between the first access equipment and the second access equipment according to the first address and the network topology of the home network.
And the second access equipment is the access equipment planned in the network topology.
Specifically, in the embodiment of the present invention, the first access device refers to an access device actually constructed and installed by a network operation and maintenance worker, and different from the first access device, the second access device refers to an access device in a network topology structure designed in advance when planning network construction.
Since the network topology structure already includes the device information of the second access device, after determining the device information of the first access device, the network management system may determine the position of the first access device in the network topology structure by matching the device information of the first access device with the device information of the second access device. Further, since the first address of each access device has uniqueness, the first address of the first access device may be matched with the third address of the second access device in the network topology, so as to determine the location of the first access device in the network topology, and thus establish a mapping relationship between the first access device and the second access device.
For example, as shown in fig. 4, a plurality of access devices are connected below the third aggregation device, and these access devices may form an access ring according to different locations, such as the first access ring, the second access ring, and the nth access ring as shown in the figure, and in each access ring, a mark may be further given to a location occupied by each access device to indicate a specific location of the access device in the access ring, such as 1, 2, 3, and 4 of the first access ring in fig. 4, where the mark of the location occupied by each access device may be referred to as a ring number of the access ring.
If the first address of the first access device is 11.1.1.1, the third address of the access device No. 1 of the first access ring in fig. 4 is 11.1.1.3, the third address of the access device No. 2 is 11.1.1.21, the third address of the access device No. 3 is 11.1.1.1, and the third address of the access device No. 4 is 11.1.1.30, the network management system may determine that the location of the first access device in the network topology is the location No. 3 of the first access ring.
Of course, if the third address matching the first address is not queried when the third address of each access device in the first access ring is matched, the network management system may match the third address of each access device in the second access ring with the first address until the third address matching the first address is queried. If the first address of the first access device is 11.1.1.1, and the third address of the access device No. 1 of the first access ring is 22.2.2.1, the third address of the access device No. 2 is 22.2.2.2, the third address of the access device No. 3 is 22.2.2.3, and the third address of the access device No. 4 is 22.2.2.4; the third address of the access device No. 1 of the second access ring is 11.1.1.1, the third address of the access device No. 2 is 11.1.1.2, the third address of the access device No. 3 is 11.1.1.3, and the third address of the access device No. 4 is 11.1.1.4, so that the network management system can determine that the position of the first access device in the network topology structure is the position No. 1 of the second access ring.
It should be noted that the third address here refers to the NEIP of the second access device. Because the first access devices installed by the network operation and maintenance personnel during the construction of the access network correspond to the second access devices in the network topology structure one to one, the actually constructed multiple first access devices can also establish the mapping relationship with each second access device in the network topology structure according to the method. For example, the mapping relationship between the first access device and the second access device determined by the network management system according to the above method may be as shown in table 1 below:
TABLE 1
It should be noted that, in the above example, only the first access ring, the second access ring, …, and the nth access ring under the third aggregation device are taken as an example for description, but it should be clear to those skilled in the art that, in practice, a network topology may include a plurality of aggregation devices, and the number of access rings connected under each aggregation device may be the same, and the number of access devices in each access ring may also be different, and the network management system may match the third address of the second access device in each access ring under the aggregation device according to the first address of the first access device until determining the third access device corresponding to the first access device. The ring numbers of the second access devices in each access ring in fig. 4 are only exemplary, and those skilled in the art may set the ring numbers of the second access devices in each access ring as needed, such as clockwise ordering or counterclockwise ordering, which is not limited to the embodiment of the present invention.
Optionally, because the network management system implements device mapping by using the first address of the first access device and the third address of the second access device, step S1031 may specifically be:
and if the network management system determines that the first address is matched with the third address of the second access equipment according to the network topology of the home network, establishing a mapping relation between the first access equipment and the second access equipment.
S1032, the network management system determines the target address of the second access device as the target address of the first access device.
S1033, the network management system determines the port connection information of the first access device.
Specifically, the network topology further includes port connection information of the second access device. And the pre-planned network topology structure comprises the target address and the port connection information of each second access device. The target address comprises a target management address and a target interconnection address, wherein the target management address is used for providing a management function of the first access device, and the target interconnection address is used for providing a connection function of the first access device and other network devices; in the invention, the access devices of the access layer are connected by adopting ring topology, so the port connection information can indicate a left connection physical port and a right connection physical port, and the left connection physical port and the right connection physical port are respectively used for connecting different access devices in the access ring.
For example, when the second access device is a router, the target management address may be a management IP of the router, such as 192.16.1.1 or 192.168.0.1, and a network operation and maintenance worker may enter a management platform of the router through the management IP, so as to implement management of the router, such as speed limit, barring of an access terminal of the router, and the like. The destination interconnect address may be an IP address used by the router to access the network, such as 111.192.14.255, through which the router may provide network connectivity services for the terminal.
After the network management system determines the mapping relationship between the first access device and the second access device in the access stratum in step S1031, the network management system may determine the target address of the second access device as the target address of the first access device, that is, determine the target management address and the target interconnection address of the first access device.
Similarly, the network management system may determine the port connection information of the first access device according to the port connection information of the corresponding second access device. It should be noted that, in the network topology, only the physical port allocation rule (for indicating the port connection relationship of the first access device) of the second access device may be included, and the port connection information described above is not included. The physical port allocation rule is used for determining the left connection physical port and the right connection physical port according to the information of manufacturers, equipment models and the like of the access equipment. If the access device of the first model produced by the first manufacturer includes the first port, the second port and the third port, the physical port allocation rule may set the first ports of all models produced by the manufacturer as left-hand physical ports and set the second ports thereof as right-hand physical ports. When the network management system determines that the first access device is produced by a first manufacturer according to the device information of the first access device and the device model is a first model, it may be determined that the first port of the first access device is a left connection physical port and the second port is a right connection physical port. Further, the physical port allocation rules corresponding to different models of access devices produced by different manufacturers may be as shown in table 2 below:
TABLE 2
| Manufacturer of the product | Model of the device | Left-connected physical port | Right-hand physical port |
| First manufacturer | First model | First port | Second port |
| First manufacturer | Second type number | First port | Second port |
| Second manufacturer | First model | Second port | First port |

As can be seen from table 2 above, the physical port allocation rules corresponding to different types of access devices produced by the same manufacturer may be the same, for example, a first port of a first type of access device and a second port of a second type of access device produced by a first manufacturer are both set as a left-hand physical port, and a second port of the first type of access device and the second type of access device are both set as a right-hand physical port; even if the access devices of the same model are different in manufacturer, the corresponding physical port allocation rules can be different, for example, the first manufacturer and the second manufacturer both produce the access devices of the first model, but the first model access device produced by the first manufacturer sets the first port as a left connection physical port, sets the second port as a right connection physical port, and the first model access device produced by the second manufacturer sets the second port as a left connection physical port, and sets the first port as a right connection physical port. Of course, the physical port allocation rule in table 2 above is only exemplary, and those skilled in the art can set different physical port allocation rules for different models of access devices produced by different manufacturers according to the needs.
The interconnection address of the access device also includes a left connection physical port address and a right connection physical port address corresponding to the left connection physical port and the right connection physical port corresponding to the access device, and for example, the target interconnection address of the second access device also includes a target left connection physical port address and a target right connection physical port address. Correspondingly, the target address determined by the network management system for the first access device also comprises a target management address, a target left connection physical port address and a target right connection physical port address.
It should be noted that each address in the embodiment of the present invention actually refers to an IP address, for example, the first address refers to a NEIP of the first access device, the second address refers to an IP address of the gateway network element, and for example, the target management address refers to a management IP address of the first access device, and the interconnection address refers to an interconnection IP address of the first access device.
S1034, the network management system determines the configuration parameters according to the target address of the first access device and the port connection information.
Specifically, after determining the target address and the port connection information of the first access device, the network management system may initialize configuration parameters of the first access device, where the configuration parameters include the target address and the port connection information of the first access device, and specifically include a management address of the first access device, a left connection physical port, a right connection physical port, and a left connection physical port address and a right connection physical port address.
Optionally, because the network management system implements management of the network device based on the SNMP, the configuration parameter of the first access device further needs to include information such as an Access Control List (ACL), an IP address of an SNMP Trap server, a port number of the SNMP Trap UDP, an SNMP Community of a simple network management protocol, an IP address of a telemeasurement server, and a port number of a telemeasurement TCP. Wherein the ACL is used for indicating an IP address field allowing SNMP access; the IP address of the SNMP Trap server actually refers to the IP address of a server which receives the SNMP Trap message in a network management system; the port number of the SNMP Trap UDP is used for indicating the port of the SNMP Trap server for receiving the SNMP Trap message; the SNMP Community is actually an access password of the network management system, and the network management system can be accessed through the SNMP Community access equipment; the IP address of the Telemetry server refers to the IP address of a server for acquiring data information in a network management system; the port number of the Telemetry TCP is used for indicating the port used by the Telemetry server for collecting data information. The UDP refers to a User Datagram Protocol (UDP), and the network management system and the access device realize information transmission through the UDP; TCP refers to Transmission Control Protocol (TCP), and a network management system acquires data information through TCP.
Of course, the configuration parameters of the first access device further include configuration parameters such as ensuring reachability of management address routing, and other configuration parameters, and those skilled in the art may perform initialization configuration on the configuration parameters of the first access device according to conventional technical means, without being limited to the above parameters.
Optionally, step S103 may further include:
s1035, the network management system sends the configuration file to the first access device through the target controller.
Specifically, after determining the configuration parameter of the first access device, the network management system may issue the configuration parameter to the corresponding first access device, so that the first access device can access the network according to the corresponding configuration parameter, and manage the first access device by the network management system.
Alternatively, as shown in fig. 5, step S1035 may include:
s1035a, the network management system sends a third message to the target controller.
Wherein the third message includes configuration parameters.
Specifically, the target controller herein may be a Software Defined Network (SDN) controller. After the network management system determines the configuration parameters of the first access device, the configuration parameters can be issued to the corresponding first access device through the target controller.
Since the configuration files required by different manufacturers and different types of access devices may be different, when the network management system sends the configuration parameters to the target controller, the manufacturer and the device type of the first access device may also be sent to the target controller, that is, the third message further includes the manufacturer and the device type of the first access device.
S1035b, the target controller determines a configuration file according to the configuration parameters.
S1035c, the target controller sends the configuration file to the first access device.
Specifically, after receiving the third message, the target controller may generate a configuration file according to the configuration parameters carried by the third message; of course, since configuration files required by access devices of different manufacturers and different models may be different, before the target controller generates the configuration files according to the configuration parameters, the manufacturer and the device model of the first access device need to be determined, so as to generate corresponding configuration files to meet the operation requirements of the first access device.
After determining the configuration file, the target controller may send the configuration file to the corresponding first access device.
In the embodiment of the invention, the network management system identifies the home location (home network) of the access equipment accessed to the gateway network element through the address information of the gateway network element, and determines the position of the access equipment in the network topology structure according to the equipment information of the access equipment and the network topology structure planned in advance by the home location, thereby determining the configuration parameters of the access equipment, realizing the automatic configuration of the access equipment, reducing the process of manually participating in the configuration of the access equipment, and improving the construction efficiency of the access network; meanwhile, the automatic configuration process of the network management system can also avoid the conditions of wrong configuration and the like caused by manual operation, and the network maintenance efficiency is improved.

The network topology structure planned by the network operation and maintenance personnel comprises aggregation equipment connected with each access ring in an access layer, access equipment included in each access ring, information of manufacturers, equipment models, interconnection ports, local addresses where the access equipment is located, machine rooms and the like of the access equipment, wherein the interconnection ports comprise a left connection physical port and a right connection physical port. The network topology may also include a management address and an interconnect address for each access device.
It should be noted that the interconnection port of the access device may be determined according to the above physical port allocation rule, and the management address and the interconnection address corresponding to the access device may be determined according to the address allocation rule. The address allocation rule may include:
a first rule, assigned according to home. Specifically, each city may be allocated with consecutive address segments, such as 111.192.0.0-111.192.14.255 or 42.236.0.0-42.236.3.255, and the management address and the interconnection address corresponding to each access device may be allocated according to the order of online of the access device on the city, for example, the interconnection address of the first online access device may be allocated as 111.192.0.0, and the interconnection address of the second online access device may be allocated as 111.192.0.1.
And a second rule, according to the distribution of the convergence equipment connected with the access equipment. Specifically, each aggregation device may allocate a continuous address segment, a target address and an interconnection address of an access device connected to the aggregation device may be determined from the address segment allocated by the aggregation device, and similarly, a management address and an interconnection address may be allocated according to an online sequence of each access device connected to the aggregation device.
And a third rule, according to the access ring allocation accessed by the access equipment. Specifically, each access ring under the rendezvous device may be allocated with a continuous address segment, and the access devices in the same access ring may also be allocated with management addresses and interconnection addresses in the order of their uplinks.
And the fourth rule is according to the ring number distribution of the access equipment in the access ring. Specifically, similar to the third rule, each access ring may be allocated with consecutive address segments, but the present rule may allocate a management address and an interconnect address in sequence to the ring number of each access device in the same access ring.
The distribution rules of the management addresses and the interconnection addresses corresponding to the four access devices are enumerated, and because the use efficiency and regularity of the distribution addresses in each distribution rule are different, a network operation and maintenance worker can optionally select one distribution rule to distribute the management addresses and the interconnection addresses for the access devices in the access layer, and the use efficiency and regularity of the addresses corresponding to each distribution rule can be as shown in fig. 7; of course, those skilled in the art may set other different allocation rules, and the embodiment of the present invention is not limited thereto. Here, the access device in the network planning process refers to a second access device in the planned network topology.
S202, the network operation and maintenance personnel install the first access equipment.
Specifically, when the network operation and maintenance personnel install the first access devices, the network operation and maintenance personnel can connect the physical ports of the first access devices according to the physical port allocation rules, and after the first access devices are powered on, the network operation and maintenance personnel judge whether the first access devices work normally through the working indicator lamps of the first access devices, and do not perform initialization configuration operation on the first access devices any more.
S203, the first access device determines a first address.
Specifically, the first address may be automatically generated by the first access device according to device information of the first access device, where the device information refers to a first access device identifier of the first access device, and the first access device identifier may be determined by a MAC address of the first access device. The process of determining the first address and the first access device identifier is a conventional technical means in the art, and is not described herein again.
And S204, the first access equipment sends a second message to the gateway network element.
Specifically, after the first access device determines the first address, the first address may be flooded in a Data Communication Network (DCN) according to an Open Shortest Path First (OSPF) protocol.
The flooding of the first address may be implemented by OSPF TYPE 10LSA messages, which transmit data via opaque link-state advertisements (LSAs). Of course, the flooding of the first address may be accomplished by other messages as well by those skilled in the art. Optionally, the OSPF TYPE 10LSA message may further include information such as the first access device identifier, the manufacturer, and the device model of the first access device.

S302, the target controller sends initial information to the network management system.
The initial information includes a target address corresponding to the first access device, and may also include information such as an SNMP Community in the configuration parameter.
Specifically, the target controller sends initial information to the network management system to indicate that the first access device is online, so that the network management system starts to manage the first access device.
S303, the network management system determines the attribute information of the first access device according to the initial information.
The attribute information includes network resources and network performance information of the first access device.
Specifically, after determining that the first access device is online, the network management system may collect network resource information and network performance information of the first access device, thereby determining the network resource occupied by the first access device and its performance, so as to manage the first access device.
