Problems solved by technology

However, in this process, not only need to switch multiple times between the forwarding CPU running in user mode and the logical CPU running in kernel mode, but also need to create session tables for tunnel packets and original packets to realize packet forwarding, which increases the occupation of session table resources and the amount of data that needs to be maintained

Embodiment Construction

[0047]Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0048] The tunnel message authentication and forwarding system provided according to the embodiments of the present disclosure is realized based on the tunnel technology. Encapsulation, for example, packet forwarding through a VPN (Virtual Private Network, virtual private network). When the packet is forwarded based on the tunnel technology with an unfixed source IP address, whether the packet is a tunnel packet can be determined by the encapsulated destination IP address and destination port number of the packet. For example, the destination IP address and destination port number corresponding to the tunnel message can be preset, therefore, when the message ...

Abstract

The present disclosure relates to a tunnel message authentication forwarding method and system, the method comprising: the current forwarding CPU decapsulates the received preset type of tunnel message to obtain the decapsulated message; when the decapsulated message is not When authenticating a message, the current forwarding CPU queries the session table created in the system according to the decapsulated message; when the current forwarding CPU does not query the session table corresponding to the decapsulated message, the current forwarding CPU queries authentication table to determine whether a session entry can be created for the decapsulated packet; when it is determined that a session entry can be created for the decapsulated packet, the target forwarding CPU Create a session entry in the session table, and forward the decapsulated packet based on the session entry. Through the above technical solution, it is possible to effectively reduce the switching between CPUs, and also effectively reduce the amount of data maintenance, and improve the forwarding performance of the system.

Description

technical field [0001] The present disclosure relates to the field of computer networks, in particular to a method and system for authenticating and forwarding tunnel messages. Background technique [0002] With the development of computer technology, data transmission between data frames or packets of different protocols can be realized based on tunneling technology, that is, the original message is encapsulated externally based on tunneling technology to obtain a tunnel message, and the tunnel message is placed in the Forwarding in the tunnel to realize cross-protocol data transmission. [0003] In the prior art, in a network forwarding system based on a heterogeneous platform, the CPUs are usually divided into two types, one is the forwarding CPU, which runs in user mode and is used to forward messages based on the session table; the other is the logic The CPU, running in the kernel state, is used to encrypt and decrypt the tunnel message, so as to send the processed mes...
