Problems solved by technology

[0004] In related technologies, when obtaining the network topology, only the network topology between physical devices, or only the network topology of the virtual network inside the server is obtained; when obtaining the virtual network topology inside the server, only the virtual machine and the virtual switch ( OVS, Open vSwitch) connection relationship; when processing LLDP packets, the third-party library libpcap is used to develop, which reduces the versatility

Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0051] The sending and receiving of LLDP messages and CDP messages is completed on network devices, but, for security reasons, it is not allowed to log in to these network devices. In this case, in order to obtain a complete network topology, the invention of the present application People found that in the data center environment, the server can see the connection with the network device. Therefore, the efficiency of network problem location can be improved by obtaining the network device connected to the network card on the server. In addition, the present application also uses SNMP to ob...

Abstract

The invention discloses a system and a method for acquiring a network topology and a server. The method comprises the following steps: acquiring virtual network topology information in the server, topology information between the server and network equipment, and topology information between the network equipment; and making a network topology according to the obtained topology information of anyone or any combination of the following items: virtual network topology information in the server, topology information between the server and the network device, and complete topology information between the network device and the network device. According to the invention, complete network topology information is obtained.

Description

technical field [0001] This application relates to but not limited to computer network technology, especially a system, method and server for obtaining network topology. Background technique [0002] With the continuous development of network technology and cloud computing technology, more and more physical network devices, physical servers, virtual network devices and virtual machines appear in the data center. In order to better locate network problems, Link Layer Discovery Protocol (LLDP, Link Layer Discovery Protocol), Cisco Discovery Protocol (CDP, Cisco Discovery Protocol) and Simple Network Management Protocol (SNMP, Simple Network Management Protocol) will be used in related technologies to obtain Network topology information. [0003] Among them, the LLDP protocol is the IEEE802.1AB standard, which stipulates that the device periodically sends LLDP packets to surrounding devices, and the LLDP packets carry configuration information, device capabilities, system name...
