Temporary Server for Service Continuity in Next Generation Network

Abstract

Real-time applicationisone of the internet-based applications that function with in a time frame that require a quick response between client and server. It has been improved to fulfill user's demand towards Next Generation Network(NGN), by injecting intensive and media-rich elements in the applications. All these innovations need sufficient bandwidth to ensure them to be delivered continuously, smoothly and successfully to the end users. However, current scenario has seen the internet population has raised rapidly so does the potential size of its traffic hat give significant impact to the online service. Hence, an efficient infrastructure is required to satisfy the demand of internet applications such as multimedia streaming. In this paper, we describe a frame work to allocate a temporary server to serve local clients within the same network domain during high traffic. This proposal has been tested on video streaming application to see the continuity of the service. from the primary server to the local alternative server instead of only pointing to one source of server. This approach is by remotely allocates a temporary server at local area that is near to the client domain network. This temporary server is allocated during network high congestion and it is done by primary server at a runtime. The temporary local server will serve the group of client in the same domain network.This method is diverse to the previous approaches such as Peer-to-Peer (P2P) networking, Content Delivery Network (CDN) and Replication/cache server (7)-(9). The previous solutions are not practical due to high cost to allocate the physical server, high maintenance and also need to verify the accurate location of the servers. In contrast, our proposal is more cost saving as we need only some space temporary during the network congestion and the server will return back to the primary server once the task of serving client's request have accomplished.
