Watchers Technique in a Distributed Network System
Wei Hai-ping · Journal of Petrochemical Universities · 2003
Pointing to the case that routers become one of intruder's main targets, the actuality and limitation of the intrusion detection technology of distributed router was analyzed and a new one called is put forward that can be used to recognize the devastating routers (it was defined as routers of throwing away or misrepresenting data packages and not supporting watchers protocol). Its core techniques are introduced in detail, namely all routers are required to fit out counter of counting correct and misrepresenting transferred events, and then devastating routers are recognized and insulated by confirming algorithm and stream conservation algorithm. The application of the technique could improve the veracity and validity of intrusion detection technology of distributed router and the safety of networks could be better assured as well.
