Analysis and characterization of novel model for P2P network in NGN

Next generation networks with the intention of converging service and control layer, with the aim of “Equal service presentation in integrated networks”, have provided a new approach to telecom operators. IMS provides a suitable opportunity for third party operators that they can participate in providing services for NGN. Some services like file sharing needs to P2P network. The existing P2P networks are done as a centralized and distributed form respectively. In fact, in current structures, resource sharing concerned with search activities is limited to centralized and private servers. This issue causes increasing the cost and reducing the system scalability due to specific servers that stores file indexes. We have proposed a new model named borderless partially centralized (BLPC) P2P network for NGN. The network resources are distributed over network nodes and the P2P network has no centralized server. The advantage of this structure is when part of the network encounters damage, the network has the ability to continue its routine activities and service is not halted. In our plan, even for the search mechanism, there is no centralized server and the network has the ability to provide services without centralized servers.
