A model of IP traceability Dynamic Collaboration technology in the denial of service attack

This paper proposes a model of IP traceability Dynamic Collaboration technology in the denial of service attack; analyzes the behavior of using illegal attack means to terminate the service capabilities of the target object in heterogeneous networks; provides a method of network transmission which is capable of dynamically adjusting data packet marking probability and making information to detect the abnormal traffic; and establishes three-layer dynamic collaboration marking architecture: traceability management layer, network proxy layer and network router layer. This paper conduct a confirmatory reconstruction of DoS attack path, and through designing collaboration model algorithm which based on threshold of data packet arrival rate, CPU usage threshold, probabilistic marking probability and dynamic adjustment factor given by collaboration architecture, as well as flexibly using identification, flag and bit offset about IP data packet fragmentation-related fields. The results show that the attack path will be accurately constructed by means of the probabilistic marking and dynamic collaboration, and IP traceability efficiency is over 97% which can achieve the purpose of traceability attack source.
