Problems solved by technology

[0005] In the prior art, in order to perform fault detection, a CFD (ConnectivityFaultDetection, connectivity error detection) protocol is defined in the layer 2 network to quickly detect the link state; further, in the CFD technology, the user needs to manually configure the MD (MaintenanceDomain, Maintenance domain), MA (MaintenanceAssociation, maintenance set), MEP (MaintenanceassociationEndPoint, maintenance endpoint), MIP (MaintenanceassociationIntermediatePoint, maintenance intermediate point), etc. Obviously, when there are many devices and interfaces in the data center network, the CFD configuration will It is very complicated, and requires detailed planning of the network before configuration, which increases the difficulty of networking

Embodiment Construction

[0036] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a fault detection method, which is applied to a TRILL network including multiple RB devices (such as a complex layer-2 network in a data center running the TRILL protocol). Each RB device includes a tree root RB device (Spine device) and multiple leaf RB devices (leaf devices); image 3 As shown, the method includes the following steps:

[0037] Step 301, after the RB device receives the LSP (LinkState Protocol, Link State Protocol) message from other RB devices, if it knows that the LSP message is used for TRILL fault detection, then determine whether the RB device is the root RB device or A leaf RB device; if the present RB device is the root RB device, perform step 302; if the present RB device is a leaf RB device, perform step 307.

[0038] In the embodiment of the present invention, by adding a specified format TLV (TypeLengthValue, type length value) field in the LS...

Abstract

The invention discloses a fault detection method and equipment. The method includes: after an RB device receives LSP messages from other RB devices, if it knows that the LSP messages are used for TRILL fault detection, then determine the RB device It is the root RB device or the leaf RB device; if the RB device is the root RB device, the root RB device creates a TFD session for the other RB device, and sends a CCM-TFD message to the other RB device ; If the CCM-TFD message from the other RB devices is received, the root RB device confirms that the other RB devices have not failed; otherwise, the root RB device confirms that the other RB devices have failed Fault. In the embodiment of the present invention, the workload of user configuration is reduced, and a link failure can be detected quickly.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a fault detection method and equipment. Background technique [0002] With the increasing number of servers and switches, the data center network is increasingly inclined to a flat network architecture, which requires the construction of a large-scale two-layer network. At the same time, the data center network has extremely high reliability requirements, and link or device failure In this case, the network convergence speed is an important indicator that users care about. Traditional Layer 2 networks use Spanning Tree Protocol to eliminate loops, but some inherent defects of this protocol make it no longer suitable for data center networks. TRILL (TRansparent Interconnection of Lots of Links, transparent interconnection of multiple links) protocol came into being. The layer data center network also inherits the design idea of ​​the three-layer routing technology ISIS (In...
