Embodiment Construction

[0060] Next, the technical scheme in the present application embodiment will be described in the present application embodiment, and it is understood that the described embodiments are merely the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, one of ordinary skill in the art is in the scope of the present application without making creative labor premistence.

[0061] Next, the concepts involved in the present application embodiment will be described.

[0062] 1, first device and second device

[0063] The above first apparatus and the second device may be any device for a message forwarding in the network. The first device and the second device can be forwarded in accordance with the schemes provided in the present application embodiments. The difference between the first device and the second device is merely the difference in "first" and "second" identification.

[0064] For example, the above network can...

Abstract

Embodiments of the present application provide a message forwarding method and device, which relate to the field of communication technology and are applied to a first device, wherein the above method includes: receiving a message, and locally storing a message related to the message in the first device. In the case of matching first session information, determine whether the first session information is session information transparently transmitted from the second device to the first device; if yes, transparently transmit the message to the second device , so that the second device performs a deep packet inspection DPI service on the message; receives the message transparently transmitted by the second device after performing the DPI service, and forwards the received message. Applying the solution provided by the embodiment of the present application for message forwarding can also effectively realize the DPI service when the received message belongs to asymmetric flow.

Description

Technical field [0001] The present application relates to the field of communication, and in particular, to a packet forwarding method and apparatus. Background technique [0002] The second-layer forwarding network can connect multiple devices together, virtualized into one device, so that the hardware resources and software processing capability of multiple devices are set together, implement multiple equipment collaborative work, unified management, and uninterrupted maintenance. [0003] Such as figure 1 The displayed two-layer forwarding network includes device 1 and device 2 two packet forwarding devices. In order to achieve traffic load balan, the general routers R1 and R2 are configured to configure two equivalents. Thus, when the computer PC1 accesses the PC 2, the packets between PC1 and PC2 can be forwarded by device 1, or by means of device 2, that is, forwarding packets through device 1 is randomly . Therefore, the uplink packet transmitted by the PC1 to the PC2 may ...
