Abstract:

With the continuous improvement of network access bandwidth,the threat of abnormal traffic to network becomes more serious,thus the defense requirement becomes more urgent. This paper describes the technology status of defending abnormal traffic. To the shortage of present technologies and applications,a defense solution based on cloud computing is proposed,with the characteristics of centralized scheduling in whole network,parallel processing,and cleaning close to the attackers. In the end the advantage of the solution is discussed.

Key words: ultra-broadband network, abnormal traffic, DDoS
