Embodiment Construction

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] figure 1 A flowchart showing a method for implementing single-node dual-homing in a distributed system according to an embodiment of the present invention, including the following steps:

[0031] Step S10, select the first single board where the port of a member link of the active aggregated link is located and select the second single board where the port of a member link of the standby aggregated link is located, the active aggregated link and the standby aggregated link The ports of the member links of the link are all distributed on different boards;

[0032] Step S20, the first single board detects the state of the active aggregation link, and the second single board detects the state of the backup aggregation link;

[0033] In step S30, switching between the active aggregated link and the standby aggregated link is per...

Abstract

The invention discloses a method and a device for realizing single-node dual home for a distributed system, comprising the following steps: a first single plate on which a port of a member link of a primary aggregation link is located and a second single plate on which a port of a member link of a standby aggregation link is located are selected, and the ports of the member links of the primary aggregation link and the standby aggregation link are distributed on different single plates; the first single plate detects the status of the primary aggregation link, and the second single plate detects the status of the standby aggregation link; and the primary aggregation link and the standby aggregation link are switched according to the detected status of the primary aggregation link and the detected status of the standby aggregation link. The invention improves the anti-failure ability of Ethernet dual-homing connection network, whole network failure can not occur when partial single plates are in failure, thereby avoiding data replication, broadcast storms and the like of the Ethernet dual-homing connection network.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a single-node dual-homing implementation method and device for a distributed system. Background technique [0002] A distributed system consists of a main control board and multiple boards. The main control board is mainly used to control the entire system and coordinate each board. Each single board is mainly used to transmit data. Each single board has a processor, which can process the sending and receiving and analyzing of messages independently, and can also perform calculation and processing of some protocols, and exchange and process messages with the main control board, etc. . [0003] In the actual application of Ethernet, the networking structure of Ethernet dual-homing connection is widely used to improve the reliability of the network. An Ethernet dual-homing network refers to an Ethernet network in which an Ethernet area is connected to another area through acti...
