The IP multimedia subsystem (IMS) is standardized by the 3rd generation partnership project (3GPP) and 3GPP2 as a new core network domain to support Internet Protocol (IP) based multimedia services over 3G networks. Session initiation protocol (SIP) which is an application layer signaling protocol is also standardized by 3GPP and 3GPP2 for session establishment, management, and transformation. In this paper, we study the SIP-based signaling delay for IMS session establishment in 3rd generation (3G) network and worldwide interoperability for microwave access (WiMax) network for different channel rates. In our delay analysis, we take into account transmission, processing and queueing delays at network nodes. The delay analysis of SIP based signaling for IMS provides an insight into the efficiency of SIP signaling for IMS.

Web services are emerging technologies that can be considered as the result of the continuous improvement of Internet services due to the tremendous increase in demand that is being placed on them. In this paper, the different facets of Web services are identified and a flexible approach to engineering complex Web services is adopted in the form of a proposed framework for the development of Web services. After the examination of its main constituent parts, it is argued that its full potential and that of Web service engineering in general, is realized through the gradual formation of a rich service grid offering value-added supporting functionality and therefore the main desirable properties of such a service grid are highlighted. Finally, the paper outlines a validation approach for the proposed framework and assembles important pointers for future work and concluding remarks.

A novel idea is proposed to provide context-aware adaptive services by use of widely adopted Session Initiation Protocol (SIP) in NGN. As the key to the idea, a new context-aware SIP proxy is worked out. It will support environment adaptability through policy decision and exchange of context information using SIP and its sibling protocols. In this new proxy, we propose to deliver context according to specific environment characteristics. Network context sensing and control is another contribution in our work. This solution helps us to control QOS and realize network and service adaptation practically. Realization of context-aware adaptation within SIP-based sessions is explained with two application scenarios.

This paper presents SLA monitoring and management framework for telecommunication services. The basic requirements of this class of systems are specified and verified in context of existing SLA standards and tools. The proposed system architecture is very general and may interoperate with the existing performance monitoring systems and management tools. The key design effort is focused on the general mapping between observed activities of the underlying telecommunication infrastructure elements and corresponding SLA instance object state construction. The proposed framework application is illustrated by the simple case study.

We propose a hybrid routing scheme that combines traditional shortest-path based OSPF mechanisms as well as a new form of explicit routing executed at the flow level. The scheme consists of finding explicit routes for real-time UDP flows, on network links that -at flow entry time- do not present more than 50% bandwidth utilisation. As for TCP packets, they will be routed on the unique least-cost path found through standard Link State algorithms. The approach improves the robustness and scalability of the network, thanks to its inherent traffic engineering mechanisms and offers better overall service for jitter and delay- sensitive real-time traffic.
