Embodiment approach

[0062] (1) If the service line card and the first SFU where the network board event is about to occur belong to the same line card frame, close the traffic outbound port of the service line card corresponding to the first SFU.

[0063] After closing the traffic outbound port of the service line card corresponding to the first SFU, the service line card no longer forwards traffic through the first SFU, but can still receive traffic from the first SFU, that is , the traffic ingress port corresponding to the first SFU of the service line card may not be closed. For example, if the service line card is an LPU in LCC1, the first SFU is an SFU in LCC1 2 , it can be determined that the service line card and the first SFU belong to the same line card frame, and then shut down the LPU and SFU of LCC1 2 The corresponding traffic outbound port.

[0064] (2) If the service line card board and the first SFU where the network board event is about to occur do not belong to the same line ca...

Abstract

The invention relates to a network board event processing method, a business line card board, and a cluster system. The method comprises the following steps: receiving a preprocessing instruction corresponding to a network board event by the business line card board, and determining a first switching network board that is about to have the network board event according to the preprocessing instruction; determining a data plane that the first switching network board belongs to; and closing a traffic exit port corresponding to the business line card board and the data plane, so that traffic canbe forwarded through other data planes. The network board event processing method provided by the invention can realize zero packet loss in the process that the network board event occurs in the switching network board, thereby ensuring the reliability of the cluster system.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a method for processing network board events, a service line card board and a cluster system. Background technique [0002] In a multi-chassis cluster system, when a network board event (such as a restart event or a power-off event) occurs on a SFU in a line card chassis or a switching cached data and data on the link) will be lost until the service line card board in the line card frame and / or other SFUs on the same data plane detect that the route is unreachable, and no longer forward data to this SFU . [0003] In the related art, a network board event occurring on a switching network board may cause packet loss, and the reliability of the cluster system cannot be guaranteed. Contents of the invention [0004] In view of this, the present disclosure proposes a method for processing network board events, a service line card board and a cluster system, so...
