Packet forwarding path obtaining method, packet forwarding method and packet forwarding apparatus

Abstract

The embodiment of the invention relates to a message forwarding path acquisition method, a message forwarding method and a message forwarding device. The message forwarding path acquisition method comprises the following steps: receiving message forwarding path generating request, and acquiring message attribute from the message forwarding path generating request; according to the message attribute, looking up a forwarding table to acquire at least one path subsection required by sending message to an interface; determining packing information for packing the message in each path subsection; and according to subsection information of each path and the packing information thereof, generating a message forwarding path. The message forwarding method comprises that a forwarding logic unit packs the message according to the received packing information and sends the packed message after receiving the message. The embodiment of the invention saves system resources, improves the message sending efficiency based on the message forwarding path, and reduces the complexity of a message sending flow.

Description

technical field [0001] The invention relates to the field of communication technologies, and in particular to a method for obtaining a message forwarding path, a message forwarding method and a message forwarding device. Background technique [0002] In the distributed system environment, the forwarding path information of the host message in the prior art is calculated and obtained by each forwarding logic unit passing through the message sending process in the message forwarding process, for example: [0003] When the host needs to send a message, the current forwarding logic unit needs to query the forwarding table from the message table item management component; calculate the encapsulation information and obtain the information of the next-level forwarding logic unit according to the query result; after that, the current forwarding logic unit according to the calculated The encapsulation information encapsulates the message, and forwards the encapsulated message to the ...

Problems solved by technology

[0004] In the process of realizing the embodiment of the present invention, the inventor found that, in the prior art, the message forwarding path information of the host is composed of each forwarding logic unit passed by the message sending path, and the forwarding table query and encapsulation information are respectively performed in the message forwarding process. It is determined by the packet analysis operation, and each forwarding logic unit needs to cache the packet when querying the entry, and wait for the source of the entry to return the query entry before continuing to process, so there are multiple caches of packets, Occupies a lot of system resources and the technical defect of the message sending process is relatively complicated
