Embodiment Construction

[0064] The following will introduce the names or terms involved in the embodiments of the present application:

[0065] A protocol data unit (protocol data unit, PDU) refers to a data unit transmitted between peer layers. The PDU of the physical layer is a data bit (bit), the PDU of the data link layer is a data frame (frame), the PDU of the network layer is a packet (packet), the PDU of the transport layer is a data segment (segment), and other higher levels The PDU is a message (message). The PDU involved in this embodiment of the present application is a message. It should be noted that, in the embodiment of the present application, the PDU may be a packet, and the packet may also be a PDU.

[0066] OSPF, is a link state routing protocol, while RIP is a distance vector routing protocol. Links are used to connect routers, and OSPF is also known as an interface state routing protocol. OSPF establishes a link state database by notifying the state of network interfaces betw...

Abstract

The embodiment of the present application provides a fault diagnosis method and its device, wherein the method includes the following steps: the centralized management device receives the first message from the first network device through the first IGP monitoring protocol session, and the first message includes the first network The first message sent by the device to the second network device; the centralized management device receives the second message from the second network device through the second IGP monitoring protocol session, and the second message includes the message sent by the second network device to the first network device The second message, the second message is of the same message type as the first message; the centralized management device performs fault diagnosis according to the first message and the second message. By adopting the embodiment of the present application, the drawbacks of the manual fault diagnosis method can be overcome, the time-consuming fault diagnosis can be shortened, and the impact on the normal working efficiency of network equipment can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a fault diagnosis method and device thereof. Background technique [0002] The Internal Gateway Protocol (IGP) is a protocol used for exchanging data flow channel information between gateways in an autonomous system (for example, an autonomous system within a certain local community). Internet Protocol (Internet Protocol, IP) or other network protocols often determine how to transmit data streams through these channel information. A gateway can be a host or a router. The IGP may include Routing Information Protocol (Routing Information Protocol, RIP), open shortest path first (open shortest path first, OSPF) protocol, intermediate system to intermediate system (intermediate system to intermediate system, IS-IS) protocol, etc. [0003] In a network using IGP, router 1 may fail to establish a connection with router 2, and route learning fa...
