Problems solved by technology

Traditional GRE packets do not support encapsulation in UDP, and cannot perform load sharing based on inner layer data, which reduces the transmission performance of packets encapsulated in the same GRE header.

Abstract

The invention discloses a chip implementation method and device for a UDP (User Datagram Protocol) encapsulated GRE (Generic Routing Encapsulation) message. The method comprises the following steps: establishing an edit behavior configuration table in a switch chip; and receiving a message and judging the type of an inner message header of the message needing to be encapsulated according to the edit behavior configuration table, and if the inner message header is a UDP message header and a GRE message header, then constructing each field value of the UDP message header and the GRE message header and replacing an original message header. According to the chip implementation method for the UDP encapsulated GRE message provided by the invention, the UDP encapsulated GRE message is realized through hardware, so that intermediate equipment can support load sharing based on inner layer data and the network forwarding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a chip implementation method and device for UDP encapsulating GRE messages. Background technique [0002] GRE-in-UDP encapsulation is based on Generic Routing Encapsulation (GRE, User Datagram Protocol) and User Datagram Protocol (UDP, User Datagram Protocol) encapsulation packets, and enables the encapsulated packets to be transmitted in IPv4 or IPv6 networks. Traditional GRE packets do not support encapsulation in UDP, and cannot perform load balancing based on inner layer data, which reduces the transmission performance of packets encapsulated in the same GRE header. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a chip implementation method and device for UDP encapsulating GRE messages. [0004] For achieving the above object, the present invention proposes following technical schem...
