Problems solved by technology

[0004] Since the message information of the forward message has changed after being processed by the service board, the message information in the reverse message fed back from the destination device is different from the message information in the forward forwarding. The output service boards may also be different. In this way, the forward message and the reverse message may not be processed on the same service board, resulting in errors in service processing.

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] An IRF virtual device is a virtual device formed by stacking multiple member devices through IRF, such as figure 1 As shown, the IRF virtual device is formed by virtual stacking of member device A and member device B, wherein each member device has multiple service boards (for example, each member device has 2 service boards). The following uses forwarding a UDP (User Datagram Protocol, User Data Protocol) message as an example to introduce the process ...

Abstract

The embodiment of the invention provides a message forwarding method and a message forwarding device. The message forwarding method is applied to an IRF virtual device. The method comprises the following steps: hashing the message information in a received first message to determine a first service board for processing the first message; and the message forwarding method is applied to an IRF virtual device. After the first message is forwarded according to the message information obtained by the address conversion processing of the first message by the first service board, the reverse messagecorresponding to the first message is received, and the message information in the reverse message is hashed to determine a second service board for processing the reverse message. Judging whether thesecond service board is consistent with the first service board; If not, synchronizing the session list item of the first service board to the second service board, determining the reverse message matching session list item in the second service board, and forwarding the reverse message after performing address conversion processing on the reverse message based on the session list item. Through this scheme, we can ensure that the business processing is carried out correctly.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a message forwarding method and device. Background technique [0002] IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) is to connect multiple devices together through IRF ports, and after necessary configuration, virtualize them into one virtual device. IRF technology can integrate the hardware resources and software processing capabilities of multiple devices to achieve collaborative work, unified management and uninterrupted maintenance of multiple devices. [0003] In an IRF virtual device, each member device includes a main control board, a service board, an interface board, and a forwarding board. After receiving a message to be transmitted (marked as a forward message), the interface board will The message information (such as quintuple information) of the message is calculated through the hash operation to which service board the forward m...
