Packet transmission method, transmission apparatus and system within LAN

Abstract

The present invention provides an internal local area network transmission method and the corresponding packet transmission device and the system. Two tiers of protocols of a UDP tier and an IP tier are simplified into one tier of protocol, namely an LIP (Local Intemet Protocol) local area interconnection protocol, to reduce the overhead bytes. When the transmission is without a connection application (such as an RTP protocol packet), an appropriate packet packaging method is chosen according to the predetermined strategy, the embodiment is that the length of the packet is less than or equal to a specific value, the packet is packaged and transmitted and correspondingly extracted and uploaded by utilizing the LIP protocol, thereby the internal local area network packet transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message transmission method, transmission device and system within a local area network. Background technique [0002] At present, what is used in the LAN is the TCP / IP protocol layered model, the bottom layer is the network interface layer; the upper layer is the network layer, which has the function of dividing and combining long messages, and the IPv4 protocol is generally used on this layer; It is the transport layer. The main protocols on this layer are TCP and UDP. These two protocols are different from the types of services provided. TCP is connection-oriented and provides high-reliability services. It is used for one-time transmission and exchange of a large number of messages; UDP is connectionless and provides high-efficiency services for exchanging a small amount of messages or information with high real-time requirements; at the top of the protocol stack is t...

Problems solved by technology

[0009] Moreover, the UDP and IP two-layer protocols also set the packet length and error detection overhead bytes respectively, resulting in repeated bytes and huge overhead.

[0010] To sum up, in the local area network, when using the unified protocol with the wide area network, that is, the traditional UDP / IP protocol to transmit multimedia messages or short data messages, the transmission efficiency of the messages will be low.
