We propose a model-based analytic approach for evaluating the overall efficiency of Forward Error Correction (FEC) coding combined with interleaving in combating packet losses in ip networks. The loss of various packets during the data transmission can be reduced by using FEC coding. This unified approach provides an integrated framework for exploring the tradeoffs between the key coding parameters such as interleaving depths, channel coding rates and block lengths. The Reed-Solomon codes facilitate the selection of optimal coding strategy used for text based and multimediaapplications with various user Quality-of-Service (QoS) requirements and system constraints. In this paper, we have evaluated the efficiency of FEC coding with interleaving in ip networks and observed that 99% of efficiency of error correction in the network. Copyright 2010 ACM.

This paper analyzes signaling traffic generated by ipmultimediasubsystem (IMS) when deployed within a hybrid WLAN IEEE 802.11 and CDMA2000 networks to provide wireless and broadband services to users. IMS provides a services infrastructure to 3G networks and beyond and delivers the capability to maintain sessions among calling parties. IMS is under varying degrees of trials and deployment. Service providers view the next generation network services as IMS based services due to the flexibility it provides for offering a variety services, including multimedia and interactive services. The hybrid network provides users the ability to utilize IMS services via WLAN and experience bandwidth intensive applications. From a business perspective, such hybrid networks would allow service providers to extend to users a variety of rich multimedia services, reduce customer churn, and increase revenue generating opportunities.

The architecture of ipmultimediasubsystem (IMS) enables converged voice, video, and data services and contains mechanisms related to session and connection control. Numerous protocols are used to perform IMS operations however the Session Initiation Protocol (Sip) plays a central role in the functionality of IMS. With increased demand for multimedia communications functionality, a software implementation of IMS limits performance and increases power consumption when controlling applications through devices like gateways, proxies and application servers. Therefore a strong desire exists to implement Sip using low power consumption hardware platforms very fast time responses. The large integration scale of the present chip technology allows for implementing all Sip mechanisms and interfaces in a single integrated chip or ASIC. In this paper, a reconfigurable hardware implementation of the session setup of IMS is described based on a hardware implementation of Sip.
