Method for forwarding message, and method and device for generating table entry

Abstract

The embodiment of the invention provides a method for forwarding a message. The method comprises the following steps of: receiving an Internet protocol packet, wherein the Internet protocol packet comprises an Internet protocol header of a public network, a tunnel protocol header and a tunnel protocol identifier field; searching a first table entry in which a tunnel protocol judgment field is matched with the tunnel protocol identifier field in a Hash control table according to the tunnel protocol identifier field; extracting a Hash factor from the Internet protocol packet according to a Hash factor extraction field of the first table entry; performing Hash operation according to the Hash factor; and determining a physical output interface used for forwarding the Internet protocol packet according to the result of the Hash operation. Moreover, the invention also provides a device for forwarding the message, and a method and a device for generating the table entry. By the method for forwarding the message, the method for generating the table entry, the device for forwarding the message and the device for generating the table entry, the problem that software occupies large storage space because different software which is used for extracting the factor used for Hash operation is needed to be developed aiming at different tunnel protocols can be solved.

AI Technical Summary

Benefits of technology

The technical effect described in this patented technology relates to methods or devices called hash tables (a type of database) which are commonly used when transferring data between networks with varying levels of security requirements such as encryption techniques like Transport Layer Security Network TLS). These systems use various algorithms to determine if any packets have been sent through them based on their source IP address(IP), destination port number, etc., without requiring custom coding for each specific communication session being carried out. By doing these calculations, it becomes possible to generate unique tables containing important pieces of evidence about network communications.

Problems solved by technology

This patented technical solution described in this patents solves issues with current methods where each type of network requires its own unique hardware or programmed logic circuitry for extraction of certain features such as identifiers called traffics during transmission over networks.
