Establishing a Trade-Off Between Unicast and Multicast Retransmission Modes for Reliable Multicast Protocols

Overview The conventional approach to reliable multicast in computer networks relies on the retransmission on demand of lost packets. Existing multicast protocols adopt a static packet retransmission scheme (unicast or multicast) to retransmit these packets, often leading to performance loss due to wasting bandwidth resources. This is worse if it consider the limited bandwidth resources wireless interfaces currently offer. Therefore, careful continuous monitoring and control is fundamental in these wireless mobile environments. This paper looks at solutions to the retransmission problem while taking into consideration network topology and the number of fixed and mobile users. Precise conditions and rules for packet retransmission are set taking into account the dynamics of the network state.

Managing convergence - the key points every company should know about

Exactly when to adopt a converged network has been one of the main questions taxing enterprises over the last couple of years. It is possible to avoid some of these problems by using strict policy management and most current routers come with...

VoIP primer: How it works - and what the jargon means

The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications. If packets are delayed by more than 250 milliseconds from end to end, a conversation can sound slightly unreal, as...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
