Abstract

The invention provides a channelizing synchronous transport module 1(STM-1) access distribution method of and a system thereof. The method comprises: multipath optical signals in a channelizing STM-1 network are respectively converted into electrical signals; an original data stream is extracted; for pure data, an effective IP data packet is extracted according to a protocol type; the data are filtered according to a filtering rule; and the data are distributed. According to the method and the system in the invention, a demand of flexible access of multiport and multi-protocol environments can be met on the light splitting and bypass condition of a complex network environment; and a demand of network safety data processing can also be met; meanwhile, flexibly extensible property of an interface can be supported and a demand on access with high density is met.

Description

technical field [0001] The present invention relates to a network data access distribution method and system, in particular to a data extraction processing distribution method and system in a channelized STM-1 (Synchronous Transport Module 1, level 1) network environment. Background technique [0002] In the past ten years, my country has developed rapidly in terms of network, e-government, e-commerce, electronic entertainment, enterprise informatization, etc., and the network has gradually penetrated into all aspects of society and daily life. However, the ensuing flood of computer viruses, hackers, information spies, and illegal content has posed a major security threat to the Internet applications of governments, enterprises and institutions, and building corresponding security equipment has become a top priority, while network access And data extraction is the first problem to be solved. Traditional network security monitoring is usually accessed in a 10 / 100 / 1000M (Mill...
