Problems solved by technology

[0009] Aiming at the above defects or improvement needs of the prior art, the present invention proposes a method for fault detection of an FCoE virtual link, the purpose of which is to quickly detect a fault in the virtual link without affecting the entire network bandwidth. This solves the problem that the failure between the FCF and the ENode cannot be quickly detected and the virtual link is in an abnormal state for a long time in the prior art

Abstract

The invention discloses a fault detection method for an FCoE virtual link, which includes: after an FCoE device sends an FCoE message on the virtual link, setting a virtual link idle timer; if before the virtual link idle timer times out, The FCF or ENode will delete the virtual link idle timer after receiving the data; otherwise, if the virtual link idle timer expires, the FCoE device sets the virtual link invalidation timer and sends a message to the peer FCoE device to maintain the FCoE virtual link. message; when the set virtual link failure timer expires, if the FCoE device has not received feedback from the peer FCoE device, the FCoE device detects that the FCoE virtual link with the peer FCoE device appears Fault. The invention only sends the message for maintaining the FCoE virtual link according to a relatively small period when the virtual link is idle, and can quickly detect the failure of the FCoE virtual link without affecting the network bandwidth.

Description

technical field [0001] The invention belongs to the technical field of Fiber Channel over Ethernet (FCoE, Fiber Channel over Ethernet), and more specifically relates to a fault detection method for an FCoE virtual link. Background technique [0002] Fiber Channel over Ethernet technology is a new protocol for transmitting FC (Fibre Channel) frames on lossless Ethernet. FCoE enables the integration of Fiber Channel and Ethernet by mapping FC frames into Ethernet frames and replacing physical Fiber Channel links with virtual links. The data in the storage network can easily cross the boundaries of optical fiber and Ethernet, thereby reducing the cost and complexity of users in storage network construction and management. [0003] A device supporting the FCoE protocol is called an FCoE device, wherein a switch supporting FCoE is called an FCoE switch (FCF, FCoE Forwarder), and a communication node supporting FCoE is called an E-node (ENode). exist figure 1 In the shown FCoE ...
