Abstract

Embodiments of the present invention provide a method for a node to withdraw from a network and a node. The method for the node to withdraw from the network includes that the network node sends a power-off notification message to an adjacent node; the network node receives a power-off ready message sent by the adjacent node, and the power-off ready message is used to indicate the adjacent node Complete the sending operation of the cached data message; the network node completes the power-off operation according to the power-off ready message. The embodiment of the present invention can realize that the data cached by the adjacent nodes can also be forwarded through the network node during the process of the network node withdrawing from the network, avoiding the problem of packet loss, and realizing the lossless network exit of the network node service.

Description

technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a method for a node to withdraw from a network and a node. Background technique [0002] In the data center, especially the storage network composed of Fiber Channel over Ethernet (FCoE) is inherited from the Fiber Channel (FC) network. business will be seriously affected. In the case of active changes in the network topology, including power-off of devices and changes in port connections, it is necessary to truly ensure that services are not damaged and that there is no packet loss on the network. [0003] In the prior art, in some service networks, before the service module exits the network, it will send a leave request message to its successor node and predecessor node respectively; after receiving the message, the successor node and the predecessor node update their predecessor and the successor node, so as to realize the direct communication betwee...
