GPSR: Greedy Perimeter Stateless Routing for Wireless Networks

Overview This paper presents Greedy Perimeter Stateless Routing (GPSR), a novel routing protocol for wireless datagram networks that uses the positions of routers and a packet's destination to make packet forwarding decisions. GPSR makes greedy forwarding decisions using only information about a router's immediate neighbors in the network topology. When a packet reaches a region where greedy forwarding is impossible, the algorithm recovers by routing around the perimeter of the region. By keeping state only about the local topology, GPSR scales better in per-router state than shortest-path and ad-hoc routing protocols as the number of network destinations increases. Under mobility's frequent topology changes, GPSR can use local topology information to find correct new routes quickly.

MPLS: The icing on the networking cake?

Iain Stevenson, networking analyst at Ovum, put it like this: "MPLS is a mechanism for labelling traffic flows to define a path through a complex network. Traditionally, a packet of data sent over an IP network goes straight from the original point...

'Selfish' routers slow the internet

More often than not, the router will choose the least congested path until it, too, becomes clogged. At that time, the router will settle on a previously neglected route. Being more altruistic, a router in some cases may end up choosing pathways...

Router holes 'threaten the internet'

However, a misconfigured router, or one that has been compromised by an online intruder, can cause chaos by advertising itself as the best path to an unrelated network. A router running BGP can communicate with its neighbours, essentially telling...

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

An IP packet is formed when a router chops up a stream of digital information into manageable chunks. The router then places two addresses in the packet's header field - one for the destination, one for the originating device.

VoIP: Don't forget about security

You can throw a huge amount of junk at the router but quality of service lets you carry on without dropping any voice packets. VoIP has many upsides but moving your telephony system to a packet-based network could leave you at the mercy of hackers.

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.
