Network dual-protocol stack parallel processing model and processing method thereof

Abstract

The invention discloses a network dual-protocol stack parallel processing model and a processing method thereof. A TCP / UDP protocol layer is used for identifying an IPv4 data packet and an IPv6 data packet; a network interface protocol layer encapsulates the data packet at a data link layer and sends the received data to an upper layer; the IPv4 protocol layer and the IPv6 protocol layer realize the dual-protocol stack parallel processing work; an ICMPv4 protocol layer and an ICMPv6 protocol layer makes response to the received PING request message and actively sends the PING request message. The realization process of the TCP / IP dual-protocol stack is layered, and the portability of the protocol stack is improved; the protocol stack can be migrated to other hardware by only needing to change few files contacted with the bottom hardware, and the program at the upper layer is unnecessary to modify; the realization of the TCP / IP dual-protocol stack in an embedded system can be massively applied to the industrial production and ordinary life, a network interface can be easily added on the equipment; in particular, the realization of the network dual-protocol stack parallel processing model has more important significance along the popularization and application of the IPv6 and the rapid development of the modern life.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a network dual-protocol stack parallel processing model and a processing method thereof. Background technique [0002] With the popularity of Internet applications and the improvement of information sharing, it has become a trend to connect embedded devices to the Internet, that is, embedded network technology. Embedded network technology mainly refers to how to connect embedded systems to the Internet, but at present, there is no exact and unified definition of embedded systems. Broadly speaking, any dedicated system that contains a central processing unit can be called an embedded system. Another general definition of an embedded system is: a dedicated computer system that is application-centric, based on computer technology, software and hardware can be tailored, and adapted to the strict requirements of the application system for function, reliability, cost, volume, and pow...

AI Technical Summary

Problems solved by technology

[0004] General embedded system hardware resources cannot accommodate protocol stacks with complex architectures, and standard TCP / IP protocol stacks based on IPv4 and IPv6 are all implemented for PCs or servers, with complex functions, and these functions are for simple, Embedded applications that implement a specific function are unnecessary and place a high burden on limited system resources
