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 an FCoE virtual link fault detection method comprising that: after an FCoE device sends one FCoE message on a virtual link, a virtual link idle timer is set; if an FCF or an ENode receives data before the virtual link idle timer is overtime, the virtual link idle timer is deleted; otherwise, a virtual link fail timer is set by the FCoE device if the virtual link idle timer is overtime, and a message for maintaining an FCoE virtual link is sent to an opposite terminal FCoE device; and when the set virtual link fail timer is overtime, the FCoE device detects that a fault occurs on the FCoE virtual link between the FCoE device and the opposite terminal FCoE device if the FCoE device does not receive a feedback of the opposite terminal FCoE device. The message for maintaining the FCoE virtual link is sent according to a smaller cycle when the virtual link is idle so that a failure situation of the FCoE virtual link can be rapidly detected and network band width is not affected.

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 ...
