An Adaptive Multipath Protocol for Efficient IP Handoff in Mobile Wireless Networks

Overview Achieving IP handoff with a short latency and minimal packet loss is essential for mobile devices that roam across IP subnets. Many existing solutions require changes to be made to the network or transport layer, and they tend to suffer from long handoff latency in either soft or hard handoff scenario, or both; and some are difficult to deploy in practice. This paper proposes a new protocol, called the adaptive multipath protocol, to achieve efficient IP handoff. Based on link-layer signal strength measurements, two different schemes are used to handle soft and hard handoff respectively. Seamless IP handoff is achieved by using multiple transport layer connections on top of persistent link-layer connectivity during soft handoff.

Has Gigabit Ethernet come of age?

As a LAN technology, Ethernet is often accused of packet-loss, bottlenecking problems and a lack of quality of service (QoS). In short, this pipe is fat, fast and cheap, leading to rumors that it may be the packet protocol to push Asynchronous...

Convergence: lower costs and extra flexibility - the IP VPN promise

The public internet is seen as the ideal transport network for this as long as the service level is understood to be 'best effort'. According to Frost & Sullivan, the lower barriers to entry of public internet-based IP VPNs, secured by technologies...

Devil's Advocate: BT strikes out with 21CN

How the wholesale monopoly will be managed remains an ongoing problem in almost any scenario. While the basic protocol of IP is fixed, despite various attempts to hijack it for proprietary purposes, the network management layer has a good deal of...

The future of IT security is fewer walls, not more

That's using VoIP with transport layer security. More of the demand is to use the Internet as a common transport mechanism. If you look at what’s hot now, VoIP as a protocol is inherently insecure. UPS and Walmart are championing the AS2 protocol.

Firms urged to embrace email encryption

Simmonds advocated the use of Transport Layer Security (TLS) - a protocol that can be used to encrypt data packets as they travel between email servers. The head of security at pharmaceuticals giant ICI has called for more businesses to encrypt...

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?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
