internet protocols communication information theory scalability IPv6 Anycast objects
In an IPv6 simulation environment,this paper extends the original Anycast concept and proposes the concept of k-Anycast communication model in IPv6 which allows k servers to cooperate with each other to accomplish a task to solve the Anycast existing scalability problem.This model can achieve dynamic join and leave of k-Anycast object without restrictions of physical location.In addition,this model can route k-Anycast service request messages to the nearest k-Anycast object that can provide the requested service,which makes it possible that all k-Anycast service request messages can be evenly distributed around the k-Anycast objects and be dealt with by the nearest k-Anycast object efficiently.In an IPv6 simulation environment,this k-Anycast communication model is applied to content delivery network(CDN) and the experimental data demonstrates that k-Anycast communication model not only enhances the service quality but also effectively saves the network bandwidth.
