In order to facilitate understanding of the present application, the following describes related art to which embodiments of the present invention relate.
Three-layer network architecture
The three-tier network architecture includes three tiers: 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 functions of realizing optimized transmission among backbone networks, and has the characteristics of reliability, high efficiency, redundancy, fault tolerance, manageability, adaptability, low delay and the like.
The convergence layer is an "intermediary" between the access layer and the core layer, i.e., 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 multiple functions of policy enforcement, security, workgroup access, routing between virtual local area networks (virtual local area network, VLANs), source address or destination address filtering, etc. The convergence layer generally adopts a switch supporting three layers of switching technology and VLAN to achieve the purposes of network isolation and segmentation.
The access layer is used for providing workstation access for the local network segment. The access layer may allow end users to connect to the network, primarily to address the inter-access needs between adjacent users, and to provide sufficient bandwidth for these accesses. 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 (media access control, MAC) address, access log, etc. The access layer can realize connection with the user by using transmission media such as optical fibers, twisted pair wires, coaxial cables, wireless access technology and the like, and distributes service and bandwidth.
Network topology
A Network Topology (NT) structure refers to the physical layout of the various devices interconnected by a transmission medium, particularly the location of computer distribution and how cables connect them. The network topology structure can reflect the structural relation of the network, and the difference of the network topology structure has important influence on the performance, the reliability, the network construction cost and the like of the network, so that the design of the network topology structure has very important position in the network construction. Common network topologies include bus topology, star topology, ring topology, and mesh topology.
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 topology, data sent by any one site needs to be transmitted over the bus and can be received by all sites 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 radial structure, and communication of the nodes in the star topology is forwarded through the central node. The star topology is applicable to file server local area networks and workstation local area networks.
In the ring topology, all nodes are connected through communication lines to form a closed ring, in the ring, data of all nodes are transmitted in one direction, after the transmitting node transmits the data, the data is returned to the transmitting node after one circle of transmission along the ring, and the transmitting node deletes the data. The ring topology is suitable for microcomputer local area network, information processing system and factory automation system.
The connections between the nodes in the mesh topology are arbitrary, each node may connect other nodes through multiple lines, such that multiple transmission paths exist between the nodes. When the nodes in the network topology transmit data, idle lines can be flexibly selected or fault lines can be avoided. The mesh topology is applicable to large wide area networks.
As shown in fig. 1, an embodiment of the present invention provides a network topology schematic, which includes a core layer, a convergence layer, and an access layer.
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 access devices of the access layer; the access layer 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 be switches, which are different in that the switches of the access layer are used for connecting terminals, the switches of the aggregation layer are used for aggregating data reported by the switches of the access layer, and the switches of the core layer are used for processing data reported by the switches of the aggregation layer. The functions of the core layer, the convergence layer and the access layer are different, and the processed data are also different, so that 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 and are merely exemplary, and the core device, the aggregation device, and the access device may also be other network devices, for example, the access device may also be a router, a multiplexer, a modem, and the like.
It should be noted that the network architecture shown in fig. 1 is only exemplary, and in practice, the network architecture may 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 connection terminal under a first aggregation device, in practice, a second aggregation device may be connected to multiple access devices, and a second access device and a third access device may be connected to multiple terminals, where fig. 1 does not show connection devices under the second aggregation device, the second access device, and the third access device. The terminal herein may be a cell phone, a computer, and may also be a cellular phone, a cordless phone, a session initiation protocol (session initiation protocol, SIP) phone, a smart phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite radio, a wireless modem card, a Set Top Box (STB), a customer premises equipment (customer premise 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 equipment, the embodiment of the invention provides an access equipment configuration method aiming at the ring topology structure of the access layer, which is used for improving the construction efficiency of the access layer. Based on the ring topology structure of the access layer, an embodiment of the present invention provides a method for configuring an access device, as shown in fig. 2, including:
s101, the 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.
In particular, the gateway network element (gateway network element, GNE) here may be a convergence 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 identification here may be a network element identification (network element identification, NEID) of the first access device and the first address may be 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, manufacturer, and device model of the first access device. The first message here may be a simple network management protocol Trap (simple network management protocol Trap, SNMP Trap) message, through which the gateway network element may report information to the network management system. The SNMP Trap is actually a mechanism by which a managed device, which may be a gateway network element, actively sends a message to a network management system.
S102, the network management system determines the home network of the first access device according to the second address.
The second address is the address of the gateway network element.
Specifically, the network management system may parse the second message, thereby determining the 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 inquiring the home network of the second address, wherein 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 Beijing city; if the second address of the gateway network element is 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 in henna. Because the access equipment of the access gateway network element and the gateway network element belong to the same home network, the network management system can determine the home network of the access equipment accessed by the network management system after determining the home network of the gateway network element.
It should be noted that, the process of determining, by the network management system, the home location of the first access device network management system according to the second address of the gateway network element is a technical means commonly used in the art, and the embodiment of the present invention is not described in detail, and a person skilled in the art may select a method for determining the home location of the second address according to needs.
S103, the network management system determines configuration parameters of the first access equipment according to the first address and the network topology of the home network, and sends configuration files to the first access equipment.
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 topology structures of each local city are pre-stored in the network management system, and the network devices accessed by each node are pre-designed in the network topology structures, including the device information of each network device, after receiving the device information (such as the first address, the first access device identifier, the manufacturer, etc.) of the first access device, the network management system can match the device information of the first access device with the device information of the network devices of each node of the access layer in the network topology structures, thereby determining the position of the first access device in the network topology structures.
Because the network topology structure is also designed with the target address and port connection information of the network equipment of each node, the network management system can determine the configuration parameters of the first access equipment according to the equipment information of the first access equipment 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:
s1031, the network management system determines the mapping relation between the first access device and the second access device according to the first address and the network topology of the home network.
The second access device is an access device planned in the network topology.
Specifically, in the embodiment of the present invention, the first access device refers to an access device actually built and installed by a network operator, and unlike 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, the network management system can determine the location 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 after determining the device information of the first 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 position of the first access device in the network topology, thereby establishing a mapping relationship between the first access device and the second access device.
As shown in fig. 4, the third aggregation device is connected with a plurality of access devices, and the access devices can form access rings according to different positions, and the first access ring, the second access ring and the nth access ring as shown in the drawing can also be marked with the positions occupied by the access devices in each access ring to indicate the specific positions of the access devices in the access ring, such as 1,2, 3 and 4 of the first access ring in fig. 4, and the marks occupied by the access devices can be called the ring numbers of the access rings.
If the first address of the first access device is 11.1.1.1, the third address of the first access device of the first access ring in fig. 4 is 11.1.1.3,2, the third address of the third access device of the first access ring in fig. 4 is 11.1.1.21,3, and the third address of the third access device of the first access device in fig. 11.1.1.1,4 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 of the first access ring in fig. 3.
Of course, if the third address of each access device in the first access ring is not found when the third address of each access device in the first access ring is found, 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 of each access device in the second access ring is found. If the first address of the first access device is 11.1.1.1, and the third address of the No. 1 access device of the first access ring is 22.2.2.1,2, the third address of the No. 22.2.2.2,3 access device is 22.2.2.3,4, and the third address of the third access device is 22.2.2.4; the network management system may determine that the location of the first access device in the network topology is the location of the number 1 of the second access ring if the third address of the number 1 access device of the second access ring is 11.1.1.1,2, the third address of the number 11.1.1.2,3 access device is 11.1.1.3,4, and the third address of the number 11.1.1.4.
Here, the third address refers to NEIP of the second access device. Because the first access equipment installed by the network operation and maintenance personnel when the access network is constructed corresponds to the second access equipment in the network topological structure one by one, the plurality of first access equipment actually constructed can also establish the mapping relation with each second access equipment in the network topological 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, the first access ring, the second access ring, …, and the nth access ring under the third aggregation device are only illustrated as examples, but it should be clear to those skilled in the art that in reality, 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 first address of the first access device with the third address of the second access device in each access ring under the aggregation device until determining the third access device corresponding to the first access device. The ring numbers of the second access devices in the respective access rings in fig. 4 are merely exemplary, and those skilled in the art may set the ring numbers of the second access devices in the respective access rings according to need, such as clockwise ordering or counterclockwise ordering, which is not limited to the embodiment of the present invention.
Optionally, since the network management system is a device mapping implemented by 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, the mapping relation between the first access equipment and the second access equipment is established.
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. The target address and port connection information of each second access device are included in the pre-planned network topology. 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 equipment of the access layer adopts ring topology connection, so the port connection information can indicate the left-linked physical port and the right-linked physical port, and the left-linked physical port and the right-linked physical port are respectively used for connecting different access equipment 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, through which a network operator may enter a management platform of the router, so as to implement management of the router, such as speed limiting, disabling, and the like of an access terminal of the router. The destination interconnect address may be an IP address, such as 111.192.14.255, used by the router when accessing the network, through which the router may provide network connection services for the terminal.
After determining the mapping relationship between the first access device and the second access device in the access layer 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 the network topology may also include only the physical port allocation rule of the second access device (for indicating the port connection relation of the first access device), and not the above-mentioned port connection information. The physical port allocation rule is used for determining the left-connection physical port and the right-connection physical port according to information such as manufacturers and equipment models of the access equipment. The physical port allocation rule may set the first port of the first model as a left-hand physical port and the second port as a right-hand physical port, as produced by the manufacturer, for the first model of the access device produced by the first manufacturer. 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 the first model, the network management system can determine that the first port of the first access device is a left-linked physical port and the second port is a right-linked physical port. Further, the physical port allocation rules corresponding to the access devices of different models produced by the respective manufacturers may be as follows in table 2:
TABLE 2
| Manufacturer (S) | Device model | Left-linked physical port | Right-hand physical port |
| First manufacturer | First model | First port | Second port |
| First manufacturer | Second model | First port | Second port |
| Second manufacturer | First model | Second port | First port |
| Second manufacturer | Third model | First port | Third 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 type of access device and a second type of access device produced by a first manufacturer each set a first port as a left-linked physical port, and a second port as a right-linked physical port; even if the access devices of the same model are different in manufacturers, the corresponding physical port allocation rules of the access devices 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 of the access device produced by the first manufacturer sets the first port as a left-linked physical port, the second port as a right-linked physical port, and the first model of the access device produced by the second manufacturer sets the second port as a left-linked physical port and the first port as a right-linked physical port. Of course, the physical port allocation rules of table 2 above are merely exemplary, and one skilled in the art may set different physical port allocation rules for different models of access devices produced by different manufacturers as desired.
The interconnection address of the access device also includes a left physical port address and a right physical port address, which correspond to the left physical port and the right physical port corresponding to the access device, and if the target interconnection address of the second access device also includes a target left physical port address and a target right 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-linked physical port address and a target right-linked physical port address.
It should be noted that, in the embodiment of the present invention, each address 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, as used herein, the destination 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 configuration parameters according to the target address and the port connection information of the first access device.
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 the management address, the left-linked physical port and the right-linked physical port, and the left-linked physical port address and the right-linked physical port address of the first access device.
Optionally, since the network management system implements management of the network device based on SNMP, the configuration parameters of the first access device further need to include information such as an access control list (access control lists, ACL), an IP address of an SNMP Trap server, a port number of an SNMP Trap UDP, SNMP Community of a simple network management protocol Community, an IP address of a technology server, and a port number of a technology TCP. Wherein the ACL is used to indicate the IP address field for which SNMP access is allowed; the IP address of the SNMP Trap server actually refers to the IP address of the server in the network management system that receives the SNMP Trap message; the port number of the SNMP Trap UDP is used for indicating a port of the SNMP Trap server for receiving SNMP Trap information; the SNMP Community is actually an access password of the network management system, and the network management system can be accessed through SNMP Community access equipment; the IP address of the telemet server refers to the IP address of a server for collecting data information in a network management system; the port number of the Telemetry TCP is used to indicate the port used by the Telemetry server to collect data information. Here, UDP refers to user datagram protocol (user datagram protocol, UDP), and the network management system and the access device implement information transmission through UDP; TCP refers to a transmission control protocol (transmission control protocol, TCP), and a network management system realizes data information acquisition through the TCP.
Of course, the configuration parameters of the first access device further include configuration parameters such as ensuring that the address route is reachable, and other configuration parameters, and those skilled in the art may perform initialization configuration for the configuration parameters of the first access device according to conventional technical means, not 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 parameters of the first access device, the network management system may issue the configuration parameters to the corresponding first access device, so that the first access device may access the network according to the corresponding configuration parameters, and implement management of the first access device by the network management system.
Optionally, 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.
In particular, the target controller herein may be a software defined network (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.
Because configuration files required by different manufacturers and different types of access devices may be different, when the network management system sends configuration parameters to the target controller, the network management system may also send the manufacturer and the device type of the first access device 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.
And 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 the configuration files required by different manufacturers and different types of access devices may be different, the target controller needs to determine the manufacturer and the device type of the first access device before generating the configuration files according to the configuration parameters, so as to produce corresponding configuration files to adapt to 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 attribution (attribution network) of the gateway network element through the address information of the gateway network element, thereby determining the attribution of the access equipment accessing the gateway network element, and determining 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 which is planned in advance of the attribution, 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 situations of incorrect configuration and the like caused by manual operation, and improve the network maintenance efficiency.

After network operation and maintenance personnel determine the network topology structures of all the cities, the network topology structures of all the cities can be input into corresponding network management systems.
The network topology structure planned by the network operation and maintenance personnel comprises convergence equipment connected with each access ring in an access layer, access equipment contained in each access ring, manufacturers of the access equipment, equipment models, interconnection ports, addresses where the access equipment is located, machine rooms and the like, and the interconnection ports comprise left-connection physical ports and right-connection physical ports. The network topology may also include a management address and an interconnection address corresponding to 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 the home location. Specifically, each local city may be allocated a continuous address segment, 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 online sequence of the access devices in the local city, for example, the interconnection address of the first online access device may be allocated to 111.192.0.0, and the interconnection address of the second online access device may be allocated to 111.192.0.1.
And a second rule is allocated according to the aggregation equipment connected with the access equipment. Specifically, each convergence device may allocate a continuous address field, and the target address and the interconnection address of the access device connected under the convergence device may be determined from the address field allocated by the convergence device, and similarly, the management address and the interconnection address may also be allocated according to the online sequence of each access device under the convergence device.
And thirdly, distributing according to an access ring accessed by the access equipment. Specifically, each access ring under the gathering device may be assigned a continuous address segment, and for the access devices in the same access ring, the management address and the interconnection address may be assigned in the online order.
And a fourth rule is allocated according to the ring sequence number of the access device in the access ring. Specifically, similar to the third rule, each access ring may be assigned a continuous address segment, but different from this rule, the ring sequence number of each access device in the same access ring may be sequentially assigned a management address and an interconnection address.
The above-mentioned distribution rules of management addresses and interconnection addresses corresponding to four access devices are listed, and because the use efficiency and regularity of the distribution addresses in each distribution rule are different, network operation and maintenance personnel can select one distribution rule to distribute the management addresses and interconnection addresses for the access devices in the access layer, and the use efficiency and regularity of the corresponding addresses of each distribution rule can be shown in fig. 7; of course, those skilled in the art may set other different allocation rules, which are not limited to the embodiments of the present invention. The access device in the network planning process refers to the second access device in the planned network topology.
S202, the network operation and maintenance personnel install the first access equipment.
Specifically, when the first access device is installed, the network operation and maintenance personnel can connect the physical ports of each first access device according to the physical port allocation rule, judge whether the first access device works normally or not through the working indicator lamp of the first access device after the first access device is powered on, and do not perform initialization configuration operation on the first access device.
S203, the first access device determines a first address.
Specifically, the first address may be automatically generated by the first access device according to its device information, where the device information refers to a first access device identity of the first access device, and the first access device identity may be determined by a MAC address of the first access device. The determining process of the first address and the first access device identifier is a technical means commonly used in the art, and will not be described herein.
S204, the first access device 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 over the data communication network (data communication network, DCN) according to the open shortest path first (open shortest path first, OSPF) protocol.
Flooding of the first address may be achieved by an OSPF TYPE 10LSA message, which transmits data via an opaque link-state broadcast (link-state advertisement, LSA). Of course, the person skilled in the art may also implement the flooding of the first address by other messages. Optionally, the OSPF TYPE 10LSA message may further include information such as a first access device identifier, manufacturer, and device model of the first access device.
Optionally, as shown in fig. 7, after step S103, the method further includes:

The initial information includes a target address corresponding to the first access device, and may further include SNMP communication information 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 attribute information of the first access device according to the initial information.
Wherein the attribute information includes network resources and network performance information of the first access device.
Specifically, after the network management system determines that the first access device is on line, the network resource information and the network performance information of the first access device can be collected, so as to determine the network resource occupied by the first access device and the performance thereof, and manage the first access device.
