Embodiment Construction

[0034] The specific implementation of the method for quickly distributing network frames with flow control in the network equipment of the present invention is described as follows in conjunction with the accompanying drawings, see image 3 , Figure 4 , after the Ethernet device of the router receives a complete frame, it generates an Ethernet receiving interrupt, which is a hardware interrupt; in the hardware receiving interrupt, it is necessary to analyze the frame header of the Ethernet frame and read out the frame header encapsulated into an Ethernet frame. The protocol type of the protocol layer data, and then according to the obtained protocol type, the analyzed Ethernet frame is added to the receiving queue of the corresponding protocol, and a software interrupt corresponding to this protocol is generated at the same time; after the analyzed Ethernet frame reaches the protocol layer Called a message, in the software interrupt of the protocol layer, the message is taken...

Abstract

The method for quick distribution of web frame in the network equipment with flow control includes: according to the entry interface information of web frame counting it into correspondent virtual interface queue, regulating working condition of network interface, then adding the web frame into correspondent protocol queue to make analysis treatment, and taking out it and distributing it. and regulating total quantity of web frame and regulating working condition of correspondent network interface. Said invention can raise working stability of router, and raise its treatment speed.

Description

technical field [0001] The invention relates to a network data transmission technology, in particular to a method for quickly distributing network frames with flow control in network equipment. Background technique [0002] The Ethernet protocol belongs to the link layer protocol. After receiving the frame-based data from the Ethernet physical layer, it processes and distributes it to the network layer or other link layer protocol modules. Among them, the way the Ethernet link layer processes and distributes Ethernet frames will affect the data processing speed of the router; Self-protection is required, otherwise unpredictable consequences will occur, such as reduced packet transmission rate and packet loss. Therefore, how to quickly distribute Ethernet frames and implement flow control on Ethernet interfaces is an important factor that determines the basic performance of a router. [0003] In the current technology, there are two main processes for processing and distrib...
