Description
Technical Field
The present invention relates to the field of data communications, and in particular, to a method and an apparatus for fast forwarding packets.
Background
In order to solve the technical problem, the embodiment of the invention adopts the following technical scheme:
with the continuous development and maturity of network technologies, various network applications enter people's lives. The increasing of network application services, such as routing, application identification, user management, content auditing, firewall and the like, put higher requirements on the forwarding speed of data streams.
Fast forwarding is also called fast forwarding, and a cache is used for processing messages, which is a technology for forwarding data streams by software. A flow is typically described using a five-tuple of packets: the source IP address, the destination IP address, the source port, the destination port and the protocol number, and a group of messages with the same quintuple are a data stream. When the message reaches fast forwarding for the first time, the fast forwarding platform creates a flow entry for the message, and the subsequent same data flow message is associated to the flow entry and used for storing data flow processing intermediate information.
For the network equipment in the network path, the fast forwarding performs data flow matching on the received message according to the quintuple of the message, determines the data flow to which the message belongs, and then performs various application service processing according to the data flow. In the fast forwarding process, each packet needs to flow through each service (application service) for service function processing, so the processing time of each packet is
Where n is the number of services and Ti is the time it takes for each service to process a message.
In the existing fast forwarding service processing process, the forwarding performance of data streams which do not need to be processed by each message and have the same processing result with each message is wasted. The data flow which does not need to process each message can only process the service of the necessary message; the data stream with the same processing result of each message can only process one message.
For the above situation, the current method usually judges the logic in the service, directly exits the processing process for the message that does not need to be processed, and transmits the message to the next service.
In the prior art, there is a defect: and storing the service processing result into a corresponding flow table entry according to the matched data flow, entering the service for the message which does not need service processing, judging whether the service processing is needed in the service, and directly transmitting the message to the next service for the message which does not need processing. The technical scheme has a performance waste point, the message which does not need to be processed by the service can be judged without entering the service, the judgment can be completed before the service is entered, and the expense of the message entering the service and then exiting the service is saved.
