Research And Implementation Of Cognitive Routing Protocol

As the network technology has developed so rapidly and the scale of the network has become more and more complex, the users and business of network become more and more day by day. User's demand is not only their service reacability, but also different kinds of requirement from the economic and performance subject. The traditional Internet just provides best effort network structure, it is hard to satisfy the trend of complex underlying network technology and multiple end users's coexistence. Therefore, based on the study of the trend in the future development of network technique, and the the requirement of social communication, the Cognitive Network (CN) has emerged. Cognitive Network studies and proposes autonomic network structure model. The research of Cognitve Network structure model is to resolve the complexity of network supporting the heterogeneity and dynamic change of current network, and it is a most important research direction in communication field in recent years. CN's design goal is to make network have the qualities of self-sensory, self-adaption, self-optimization, self-organization and so on to satisfy a series of end to end goals.Cognitive routing protocol is the hotspots of cognitive network structure. It realizes cognitive properties by employing proper routing technology, and then gets the goal of enhancing network performance and reduces network cost. "Research and Implementation of Cognitive Routing Protocol" is mainly based on the network model and parameter studied and predicted by the knowledge plan of Cognitive Network to research relative routing mechanism in cognitive network,and then realize routing's self-configuration,self-management and self-adaption to current network traffic model to optimize network resource utilization ratio,finally to improve different business end to end QoS. This paper first analysises Cognitive Network's current development situation, introduce the structure and model of Cognitive Network.Then, analysises the requiremet of cognitive routing to make outline design of cognitive routing protocol, describe cognitive routing protocol's component elements and how to make implementation. Finally, this paper based on the OSPFv3 protocol to implement the cognitve routing protocol model and make validation by analysising the testing results. At the end of this paper, proposes some extensive suggestion and research direction.
