Embodiment Construction

[0056] In order to highlight the technical features and advantages of the present invention, the present invention will be described in detail below with reference to the figures.

[0057] The key of the present invention is: the third layer in the network, i.e. the network layer (the seven-layer OSI model is referring to figure 1 ), a processing method and implementation device for IP data packets are proposed, and a modularized implementation scheme is provided for the processing of data packets from MAC to network layer.

[0058] refer to figure 2 The flow chart of device, content of the present invention is as follows:

[0059] An IP message processing device is characterized in that it includes a sequentially connected message receiving module, a format processing module, a length checking module, an error checking module, a padding processing module, a decapsulating processing module, an extracting and searching keyword module, and a routing module. In the table item ...

Abstract

The invention provides an IP message receiving processing device and processing method. Data message information from an MAC layer is cached by a message receiving module, and meanwhile, the message receiving module controls a receiving speed; after the received data message information with a proper speed is placed in a cache unit, a format processing module reserves a blank header for subsequent processing and adds head and tail information; then, the data is transmitted to a length check module and an error check module to check whether the data message information is correct; the data message information having no error is transmitted to a filling processing module and a decapsulation processing module thereafter at one time, and maximum and minimum packet limit of a network layer are cooperated by these modules; thereafter, the data message information is transmitted to a keyword extraction and lookup module to cooperate with a subsequent routing table entry lookup and result return module to realize a routing algorithm; and finally, a processed IP message is sent to a transport layer by a forwarding module.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for receiving and processing IP (Internet Protocol, Internet Protocol) messages. The so-called IP packet is the packet information transmitted one by one at the network layer. Background technique [0002] Today's world is the era of information technology explosion, information technology has been revolutionary development, even related to the economic lifeline of a country, all countries are vigorously developing information technology, the popularization and development of information technology cannot be separated from the network, it is The development of the Internet stimulates the widespread dissemination of information technology more rapidly. Therefore, the Internet is the cornerstone of the development of this era and an important medium to promote the rapid development of information technology. If a country wants to vigorously develop...
