Embodiment Construction

[0023] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] figure 1 It is a flow chart of the first embodiment of the loop processing method of the present invention, as figure 1 As shown, the loop processing method includes:

[0025] Step 101, when a loop occurs in the first service, block the first service;

[0026] Step 102, blocking the second service associated with the first service according to the preset linkage relationship;

[0027] Wherein, before step 102 is performed, the second service associated with the first service may be pre-configured as a linkage relationship. In the embodiment of the present invention, there may be one or more second services associated with the first service. The first service and the second service are configured as a linkage relationship. When the first service is blocked due to a loop, the second service can be All second s...

Abstract

The embodiment of the invention relates to a method and device for processing a loop. The method for processing the loop comprises the following steps of: when a loop occurs in a first service, blocking the first service; according to the preset linkage relationship, blocking a second service associated with the first service; and according to the blocking time and the threshold value of retry times, determining whether to block the first service and the second service permanently. In the embodiment of the invention, when a loop occurs, the first service is blocked, and the second service associated with the first service is blocked according to the set linkage relationship. The convergence time of the loop processing process can be reduced, the convergence speed of a communication network can be improved when a loop occurs in the service, and the influence of the loop on the communication network can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a loop processing method and device. Background technique [0002] When users in the Ethernet need Layer 2 interworking, the packets are directly forwarded through Media Access Control (Media Access Control; MAC for short) addressing. The MAC address learning mechanism of a Layer 2 device is as follows: when an interface receives a message whose source MAC address is not in the address table, it adds the correspondence between the MAC address and the interface to the address table, and subsequently receives a destination MAC address of the For a packet with a MAC address, the packet is forwarded from the interface corresponding to the MAC address according to the correspondence in the address table. The updating mechanisms that can be adopted for the learned MAC address include: normal aging and interface moving. The normal aging update mec...
