Abstract
The thesis is focus on work monitoring technology in high speed
Retwork environment.
At present,with the development of the / technology,work—based applications were enjoy the benefit that work gives the two edges of the sword,work security issue is
ing more serious,the Hacking intrusion is the most dangemus attack intrusion Detection System)is the most effective way to Hacking defencing.
In the high work environment。there are three issues in NIDS: Lowest loss rate in data capturing;high processing in analysis engine;high
nicety monitoring part is the foundation of the NIDS,it
executes the work packet capturing,filtering and forwarding.
work monitoring system we designed adoptes our specially designed model”work Packet Captudng&Load Balancing”.We use it to solve the high loss rate problem in high work packet
capturing and give some benefits to NIDS design.
We analysed the process of NIDS,merged work traffic forwarding work queue management,designed the work Packet Capturing&Load Balancing ,we developed work
monitoring system in high work environment using the open OS—-——
Linux.
At last。we analyze the system by doing ;we give some
advice to the future research WOrk.
Keyword:High work NIDS Packet Capturing Balancer
