Scalable System

The demand for scalability in replicated distributed real-time database systems (RDRTDBS) is still explorative and, despite an increase in real-time applications, many challenges and issues remain in designing a more scalable system. The objective is to improve the scalability of the system during system scale up with new replica sites. Existing research has been mainly conducted in maintaining replica consistency between different replicas via replication protocol. However, very little research has been conducted towards improving scalability and maintaining mutual consistency and timeliness. Consequently, the ultimate aim of this chapter is to improve scalability in RDRTDBS such that performance of the system does not degrade even though new replica sites are added.

Peer To Peer Network

Recently, some proposals suggest to use a peer-to-peer network instead of servers to facilitate SIP user registration and location in IMS communication systems. Due to the lack of central authority, security issue becomes one of the main problems in such P2P IMS systems. In this paper, we propose a novel security architecture for P2P IMS system. By using this architecture, our P2P IMS system becomes a fully distributed secure system in which there is not a central server indeed. Furthermore, our system is a scalable system which is capable of anonymous yet accountable real time communication based on SIP protocol which enables the system compatible with any existing IMS systems.
