Description

Method and device for establishing border gateway protocol device network topology

technical field

The invention belongs to the technical field of communication, and in particular relates to a method and a device for establishing a border gateway protocol device network topology.

Background technique

The dependence on computer network in the information age makes the reliability of computer network operation very important, and puts forward higher requirements for network management. According to the definition of Open System Interconnect (OSI), network management mainly includes five functional domains: fault management, configuration management, performance management, security management and billing management. Among the above five functional domains, configuration management is the foundation, and its main functions include discovering the topology of the network, monitoring and managing the configuration of network devices. All other functions are based on the known topology of the network. The main purpose of network topology discovery is to obtain and maintain the existence information of network nodes and the connection relationship information between them, and draw the entire network topology map on this basis.

At present, the Internet and other large private networks are composed of a large number of autonomous systems (Autonomous System; AS), and the routing structures of these networks are generally divided into two types: intra-domain routing and inter-domain routing. The routers in the autonomous system exchange routing information with each other through intra-domain routing protocols. Generally, intra-domain routing protocols are divided into distance vector protocols and link state protocols. The former is represented by the Routing Information Protocol (RIP), and the latter is commonly used by the Open Shortest Path First (OSPF) protocol and the Intermediate System to Intermediate System (IS-IS) protocol. Autonomous system boundary routers exchange routing information through an inter-domain routing protocol. The current inter-domain routing protocol standard on the Internet is Border Gateway Protocol (BGP).

In current networks, Border Gateway Protocol BGP is frequently used. BGP is an exterior gateway routing protocol (or inter-domain routing protocol) designed for the TCP/IP (Transmission Control Protocol/Internet Interconnection Protocol) Internet, and is used between multiple autonomous domain systems AS. BGP is a distance vector routing protocol, but it is neither based on a pure link state algorithm nor a pure distance vector algorithm. In the Internet, the main function of BGP is to exchange network reachability information with other autonomous domain systems (AS) through BGP. Each autonomous domain system AS can run different interior gateway routing protocols. Among them, the BGP update information includes the paired information of the network number/autonomous domain path, and the autonomous domain path includes the autonomous domain string that must be passed through to reach a specific network. These update information are transmitted through TCP to ensure the reliability of transmission.

In traditional network management, for example, the network management supported by Simple Network Management Protocol (SNMP) is used. Among them, SNMP is composed of a set of network management standards. It manages a single network element through the information table ifTable and IP address table ipAddrTable in RFC-1213, as well as private SNMP information of the manufacturer. It focuses on the physical layer and lacks global BGP equipment Management methods such as building network topology; some management methods that can build network topology for global BGP devices need to set up a separate server for each network node and control and manage it through the global server, which has the disadvantages of high cost and complex system .

Fig. 1 is a schematic flowchart of a method for establishing a BGP device network topology according to an embodiment of the present invention. As shown in FIG. 1, the method S100 for establishing a network topology of a Border Gateway Protocol device may include: S110, judging whether the configuration information of the network node device includes Border Gateway Protocol BGP configuration information, wherein the BGP configuration information includes the network node device Information about the local autonomous domain system BGPLocalAS to which it belongs. S120. When the BGP configuration information is included, create a label of the BGP device in the BGP network topology according to the autonomous domain system BGPLocalAS information in the BGP configuration information. In an example, the network node device may be a router, a switch, a server, or a host. When the obtained network node device configuration information includes BGP configuration information, it can be determined that the network node device is a BGP device, such as a BGP router. The method creates a BGP device mark in the BGP network topology by using the local autonomous domain system BGPLocalAS information in the obtained BGP configuration information of the network node. Realize the initial establishment of the network topology of the BGP equipment, without the need to set up a separate server for each network node and control and manage it through the global server, which effectively reduces the system establishment cost and system complexity, and can realize automatic monitoring of network node equipment. Discovery is added automatically. In some examples, the method may further include: comparing the data value of the BGPLocalAS information with a preset range to determine whether the BGPLocalAS information is normal. For example, it is judged whether the data of the BGPLocalAS item of the node device is 0, -1 or greater than 65535 and other abnormal and incorrect autonomous domain AS information. In some examples, the method may further include: when it is determined that BGPLocalAS is normal, determining whether a BGP network topology containing a BGP device already exists; if it is determined that a BGP network topology containing a BGP device does not exist, generating information capable of identifying the BGP device Group, the information group includes the BGPLocalAS information to which the BGP device belongs and the label of the BGP device.

Fig. 2 is a schematic diagram of an exemplary application scenario of a method for establishing a BGP device network topology according to an embodiment of the present invention. As shown in FIG. 2 , the application scenario includes: network node devices such as managed device 210 , managed device 220 and managed device 220 in the figure; and a network management server such as a network management system NMS. In some examples, the method may include acquiring or receiving configuration information of the network node device based on the Simple Network Management Protocol SNMP. For example, the above-mentioned managed device 210, managed device 220 and managed device 220 are respectively provided with SNMP agents to establish an environment for SNMP network management and operation. In some examples, the managed devices on each network node 210, 220, 230 of the target network can receive or transmit information through an SNMP agent, and the SNMP agent has corresponding managed device-related management information for converting them into In a format compatible with SNMP, the relevant management information here can be, for example, the configuration information of the managed device. Furthermore, the SNMP agent can pass the information and data to the network management system NMS for processing through the SNMP protocol; the NMS runs the application program to realize the monitoring of the managed device The function of managing equipment, NMS can also provide a large number of processing programs and necessary storage resources for network management.

In some embodiments, the method may further include acquiring or receiving configuration information stored in a management information base (MIB) of the network node device based on SNMP. For example, configure a management information base MIB (Manage Information Base) on each network node of the target network, which can collect and store management information, and the SNMP agent corresponding to each managed device can obtain and store all information through the configured MIB. Agent's configuration information for managed devices.

In some examples, the method can include accessing the SNMP MIB. For example, the access to the MIB can be performed through the application layer protocol, so as to collect the information in the corresponding network node from the MIB. Specifically, a network information collection process can be used to access the MIB of SNMP through the application layer protocol SNMP, and collect configuration information of network nodes 210, 220, 230, such as configuration data information of IP addresses and interfaces, and configuration information of common network devices. Basic configuration information, etc. In some implementation manners, the method can access the MIB of SNMP through an application layer protocol, and can also collect BGP configuration data information of network nodes. Wherein, if the network node is configured with BGP, the BGP configuration of the network node may include BGP local autonomous domain AS information (BGPLocalAS information), BGP peer table (BGPPeerTable) information, and the like.

According to some embodiments, the BGP configuration information in the method may also include peer table information BGPPeerTable corresponding to the BGPLocalAS information; the method may also include: creating a BGP network according to the peer table information BGPPeerTable in the BGP configuration information Connection relationship between a BGP device and other BGP devices in the otherid2ology. In some examples, the peer table information in the method includes the remote address of the peer, the identifier of the peer and the local address; the method may also include: according to the remote address of the peer and the identifier of the peer Determine whether the BGP network topology of the peer BGP device that includes the BGP device already exists; if it is determined that the BGP network topology of the peer BGP device that includes the BGP device does not exist, then according to the remote address and local address of the peer, Establish the connection relationship between the BGP device and the peer BGP device of the BGP device. In an example, the data format of the peer table information BGPPeerTable is given in Table 1:

Table 1: Peer table information BGPPeerTable

According to the data format of the peer table information BGPPeerTable in Table 1: peer identifier bgpPeerIdentifier, peer network node device IP address bgpPeerRemoteAddr, local network node device IP address bgpPeerLocalAddr. In some examples, the method can obtain the remote IP address of the BGP peer corresponding to the address through the BGPPeerRemoteAddr field in the BGPPeerTable (that is, the peer IP address of the neighbor relationship indicated by this field), and can use the destination IP address destIP to Indicates the value Y of this IP address; the peer device can be known through the value destIP of the peer IP address; it can be judged whether the learned peer device has a corresponding node device mark in the aforementioned BGP topology diagram, such as device If it does not exist, the connection will not be made. If there is an icon of the peer node device, the local IP address of the BGP peer corresponding to the address can be obtained through the local IP address (that is, the BGPPeerLocalAddr in the table) field ( That is, the local IP address of the neighbor relationship indicated by this field), and the source IP address srcIP is used to represent the value X of this IP address. In some examples, the method may also include, in the aforementioned BGP topology, establishing the BGP peer table corresponding to the node device's mark, such as the device icon (the icon of the device corresponding to srcIP) and its peer device icon (destIP icon of the corresponding device), and record srcIP and destIP in the attribute information of this connection, indicating the IP information configured at both ends of this connection.

Fig. 3 is an exemplary flow chart of the BGP configuration information collection process in the method for establishing a border gateway protocol device network topology according to an embodiment of the present invention. As shown in Figure 3, the BGP configuration information collection process may include:

S310, accessing the MIB of each network node to collect BGPLocalAS information. In some examples, the information stored in the MIB of each network node may include configuration information of the node device. If the node where the node is located has a BGP device, such as a BGP router, or the node device is configured with the BGP routing protocol, the MIB may include information in the BGP configuration MIB data table, for example: BGPLocalAS information. In some examples, the method can use a network information collection process to access the SNMP MIB through the application layer protocol SNMP. In addition to collecting basic network node IP addresses and interface configuration data information, it can also collect information from the MIB when accessing the MIB. The configuration information of the corresponding collected device in its node, for example: the BGPLocalAS information in the BGP configuration information of the node device configured with the BGP protocol.

S320, judging whether the BGPLocalAS information is collected, if the BGPLocalAS information is collected, then enter step S330; otherwise, end. In some examples, the configuration information collected by accessing the MIB is judged and identified to determine whether the BGPLocalAS information has been collected. If it is determined that BGPLocalAS information has been collected, it means that the node device has BGP configuration information, thus indicating that the network node is configured with BGP routing protocol or that the collected node device is configured with BGP device, thereby entering S330. In some examples, if it is determined that BGPLocalAS information is not collected, it means that there is no BGP configuration information, thereby indicating that the network node is not configured with a BGP routing protocol or that the collected node device is not configured with a BGP device, thereby ending the collection process, for example. The collection of the BGP configuration information of the node device of the current network node can be ended or stopped, and the collection of the BGP configuration information of the node device of the next network node can be started, for example, return to S310.

S330. Access the MIB to collect the information of the peer table BGPPeerTable. In some examples, the information stored in the MIB of each network node may include configuration information of the node device. When it is determined that the node device where the device is located is configured with the BGP routing protocol or is configured with a BGP device, such as a BGP router, the MIB may include the BGPPeerTable information of the BGP configuration MIB data table. In some examples, the method can also utilize the network information collection process to continue to visit the MIB of SNMP through the application layer protocol SNMP, so as to collect the peer table BGPPeerTable information in the BGP configuration information of the node device configured with the BGP protocol.

S340. Based on the collected BGPLocalAS information and the peer table BGPPeerTable information, form a BGP information object BGPInfo, and then end the collection process. In an example, the data format of the information object BGPInfo is given in Table 2:

Table 2: Information object BGPInfo

BGP Info localAs bgpPeerTable

In some examples, the method may also include collecting the object BGPInfo as a result. By collecting the BGP configuration information and program judgment logic of the corresponding network devices in the MIB in the SNMP environment, it is realized to use the BGPLocalAS information in the BGP configuration information to generate BGP topology diagrams and device icons, and to use the BGP peering information in the BGP configuration information. The information in the body surface establishes the connection between the local device and the peer device, draws the corresponding BGP network topology, and identifies the BGP protocol. As a result, it is possible to automatically discover the BGP network topology, generate a BGP topology map, and provide BGP visualization information based on the topology map, thereby bringing rapid BGP network fault location, visualization of BGP protocol management, and improvement of network management, operation and maintenance efficiency. and other beneficial effects, so that network administrators can quickly and intuitively grasp the BGP topology information of the current network, and provide accurate and effective graphics for network administrators, so as to realize visual inspection, that is, visualization of BGP protocol management.

In some examples, various network device configuration information of each network node, including BGP configuration information, can be obtained through S310-S340, so that the identification of whether the node device is configured with the BGP protocol and the discovery of BGP devices can be realized in the network managed by SNMP , which realizes the automatic discovery of configuration information according to the BGP network configuration, and provides a basis for the management of the BGP protocol such as BGP node topology drawing and fault location.

Fig. 4 is an exemplary flowchart of a method for establishing a BGP device network topology according to another embodiment of the present invention. As shown in Figure 4, the method may include:

S410, obtaining a collection result. In an example, configuration information of the node device transmitted from a certain network node may be received, for example, the coordination information includes an information object BGPInfo. Go to S420.

S420. Determine whether the BGPLocalAS item in the BGPInfo of the node device has data, and the data is not 0 or -1. If it is no (that is, there is no data, or the data is 0 or -1), do not continue to process (that is, end the drawing process); if it is yes, you can enter S430.

Step S430, creating a BGP network map (BGP topology map), such as BGP.map topology map, whose name may be BGP.map. Enter S640.

S440, create an information group corresponding to the BGPLocalAS item of the node device in the BGP topology map, which can be used to place relevant information and data related to the node device in the topology map, and the name of the information group can be used by BGPLocalAS AS number (ASNumber) to represent. Enter the S450.

S450. An icon of the node device may be created in the BGP topology diagram and placed in the information group. Enter S460.

S460, judging whether there is BGP peer table data of the next node device. If it is yes, enter S470, if it is otherwise, do not continue to process, it means that each piece of data in the table has been processed, and the drawing process can be ended.

S470. When the peer IP address of the neighbor relationship indicated by this data is obtained from the data in the BGPPeerRemoteAddr field, use the destination IP (destIP) to represent the value of the peer IP address. Enter S480.

S480. Obtain the peer device according to the destIP. Enter S490.

S490, judging whether the peer device has a corresponding node device icon in the BGP topology map, if yes, go to step S500, if not, go to S460.

S500. Using the source IP (srcIP) to represent the local IP address of the BGP connection of the neighbor relationship indicated by the data obtained from the data in the BGPPeerLocalAddr field, the value of the local IP address. Enter S510.

S510, establish (for example: draw) in the BGP topology diagram the connection between the node device icon (local node device) of the network node that transmits the BGPInfo and the learned icon of the peer device, and here Record the corresponding srcIP and destIP in the attributes of a connection to indicate the IP information configured at both ends of the connection. Enter S460.

Therefore, based on the collected BGP configuration information of each network node, a corresponding BGP topology map is generated, and the SNMP-based BGP protocol identification is realized, and then the BGP network topology discovery is completed. Moreover, the topology map can be used for management. At the same time, the BGP visualization information provided by it realizes the visualization management of BGP based on SNMP, and can quickly locate faults.
