Problems solved by technology

Since it cannot be guaranteed that SFU1 of LCC2 and SFU1 of LCC1 are isolated at the same time, if SFU1 of LCC2 is isolated earlier than SFU1 of LCC1, the LPU and FCU1 (Fabric Connection Unit, also known as the switching connection unit, which are directly connected to SFU1 of LCC2 SFU1 of LCC2 will not send data to SFU1 of LCC2, but the LPU of LCC1 cannot perceive that SFU1 of LCC2 is isolated, and will continue to send cross-chassis data to LCC2 through the data plane where SFU1 is located, and FCU1 will determine that SFU1 of LCC2 is not available. and discard the data from LCC1 until the route converges, and each LPU no longer sends data to SFU1 of LCC2
[0004] In related technologies, the upgrade of the cluster system may cause packet loss, resulting in unguaranteed reliability of the cluster system and affecting the forwarding capability of the cluster system

Abstract

The invention relates to an upgrading method for a cluster system, an active main board and the cluster system. The method comprises the steps that after a smoothing upgrading instruction on a to-be-upgraded data plane in the cluster system is received, a service cable clip plate of an original cable clip frame is informed to close a traffic output port corresponding to the to-be-upgraded data plane; line connection information of the to-be-upgraded data plane is checked; and on the condition that it is determined that line connection of the to-be-upgraded data plane passes checking, the service cable clip plate of the original cable clip frame is informed to open the traffic output port corresponding to the to-be-upgraded data plane. According to the upgrading method for the cluster system, the active main board and the cluster system, zero packet loss can be achieved in the upgrading process of the cluster system, therefore, the reliability of the cluster system can be guaranteed, and wire-speed forwarding can be guaranteed in the upgrading process of the cluster system.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method for upgrading a cluster system, an active main control board, and a cluster system. Background technique [0002] figure 1 A schematic diagram of a stand-alone forwarding system in the related art is shown. like figure 1 As shown in the figure, in a single-machine forwarding system, each line (line) of an SFU (Switching Fabric Unit, also known as a line card frame switching network board) is respectively connected to the LPU (Line Processing Unit, line processing unit) of this frame, Also known as the service line card board), the traffic of this frame can communicate across LPUs through the switching network. After the SFU is started, all lines are turned on by default. When a certain SFU is in an abnormal state (for example, powered off or restarted), first isolate the SFU in the abnormal state to make all lines unreachable. After an SFU is ...
