Problems solved by technology

If the length of FKA_ADV_PERIOD is shortened, although the above problems can be solved, the shorter period will cause a large number of control packets to be transmitted in the network, which will affect the network bandwidth.

Embodiment 1

[0041] see image 3 , image 3 It is an implementation flow chart of Embodiment 1 of the FCoE virtual link fault detection method of the present invention. This embodiment is applied to figure 1 The shown FCoE network structure is used as an example for illustration. Assuming that the network link between Transmit switch 1 and Transmit switch 2 fails, the detection method includes the following steps:

[0042] Step 301: the network link between Transmit switch 1 and Transmit switch 2 fails, and Transmit switch 1 and Transmit switch 2 discover this failure, all send the FIP keeping alive request (FIP Keep Alive Request) message that comprises REPLY_FKA_ADV_PERIOD, transmit Transmit The message sent by the switch 1 is recorded as a FIP Keep Alive Request 1 message, and the message sent by the Transmit switch 2 is recorded as a FIP Keep Alive Request 2 message.

[0043] In this step, the REPLY_FKA_ADV_PERIOD in the FIP Keep Alive Request 1 message and the FIP Keep Alive Reques...

Embodiment 2

[0056] Figure 4 It is a schematic diagram of the FCoE network structure applied in Embodiment 2 of the present invention, Figure 4 The FCoE network includes Transmit switch 1 and Transmit switch 2.

[0057] see Figure 5 , Figure 5 It is an implementation flowchart of Embodiment 2 of the FCoE virtual link fault detection method of the present invention. Assuming that the network link between Transmit switch 1 and Transmit switch 2 fails, the detection method includes the following steps:

[0058] Step 501: The network link between Transmit switch 1 and Transmit switch 2 fails, and Transmit switch 1 and Transmit switch 2 discover this failure, all send the FIP Keep Alive Request message that comprises REPLY_FKA_ADV_PERIOD (set to 100ms), and Transmit switch The message sent by 1 is recorded as a FIP Keep Alive Request 1 message, and the message sent by the Transmit switch 2 is recorded as a FIP Keep Alive Request 2 message.

[0059] In this step, the Transmit switch can...

Abstract

The invention provides a method, system and device for detecting virtual link faults based on fiber channel over Ethernet (FCoE). The method comprises the following steps: when a transmit switch finds out a network fault, sending an FCoE initiation protocol (FIP) keep alive request message containing a response period; receiving the FIP keep alive request message by an FCoE device, establishing avirtual link ageing timer, setting timeout duration of the virtual link ageing timer in accordance with the response period, and sending a message for keeping an FCoE virtual link to an FCoE device at an opposite end; and when the virtual link ageing timer is subjected to the timeout duration, if the FCoE device does not receive feedback from the FCoE device at the opposite end, detecting the FCoE virtual link fault between the FCoE device and the FCoE device at the opposite end. According to the invention, the failure condition of the FCoE virtual link can be quickly detected on the premise of not influencing network bandwidth.

Description

technical field [0001] The present invention relates to the technical field of Fiber Channel over Ethernet (FCoE, Fiber Channel over Ethernet) based on Ethernet, in particular to a detection method, system and device for an FCoE virtual link failure. Background technique [0002] The FCoE protocol is a transmission protocol that carries the FC protocol on the Ethernet. Such as figure 1 It is a schematic diagram of the FCoE network structure in the prior art. In the FCoE network, devices supporting the FCoE protocol are called FCoE devices, wherein switches supporting the FCoE protocol are called FCoE transmission (FCF, FCoE Forwarders) switches, and devices supporting the FCoE protocol The communication entity device is called an Ethernet node (ENode); on an FCoE network, an Ethernet switch that does not support the FCoE protocol but can transmit FCoE packets is called a Transmit switch. exist figure 1 In the FCoE network shown, before the FCoE packets need to be exchange...
