Method and network appliance for processing packet

Abstract

The invention provides a method and network equipment for processing messages. A plurality of Sockets are created aiming at the same concrete protocol, each Socket is bound with a subtype of the concrete protocol; after the network equipment receives a message, the network equipment confirms the Socket bound with the subtype of the concrete protocol according to a concrete protocol identifier and a subtype identifier carried with the message, and sends the message into a buffer of the Socket. The method and the network equipment of the invention can send the message of the important subtype in a concrete protocol into a separate Socket buffer, can not affect the message of the important subtype due to overlarge communication volume of other messages, can make a preferred reading to the Socket buffer of the important subtype by an application program, avoids the loss of the message of the important subtype or the failure to process the message of the important subtype in time, and assures the stability of a network system.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for processing messages and network equipment. Background technique [0002] Socket (Socket) is currently the most widely implemented method for mutual access between processes. Its main function is to map protocol-related messages sent by one process to another specified process. For example, after a network device receives a message, if the message is sent to the network device, it needs to send the message to the application program of the network device through the Socket corresponding to the protocol type of the message. [0003] At present, Socket is mainly divided into four types: Transmission Control Protocol (TCP) Socket, User Datagram Protocol (UDP) Socket, Raw (RAW) IP Socket and Raw Link (RAW Link) Socket. Among them, TCP Socket and UDP Socket are distinguished by the source address, destination address, source port number and destination port number of th...

Problems solved by technology

However, there are different subtypes of messages in a specific protocol, and their functions and importance are different. For example, OSPF protocol messages are divided into 5 subtypes of messages, namely keep-alive (hello) messages, database description (DD ) message, request (Request) message, update (Update) message and response (Ack) message, among them, the hello message is used to discover and maintain the neighbor relationship, and its priority is much higher than other subtypes of messages However, since all subtypes of the same specific protocol are sent to the same Socket buffer, the overflow of the Socket buffer may cause important hello packets to be lost, or the As a result, important hello packets cannot be processed in time, resulting in serious consequences such as interruption of neighbor relations and failure of services.
