Light Trails: A Sub-Wavelength Solution for Optical Networking

Tags:
optical networking

Overview All-optical networks are able to transport data from source to destination entirely in the optical domain. This is a departure from current optical networks that rely on Optical-Electrical-Optical (OEO) conversion at each intermediate connection node to route data properly. The opacity inherent in traditional networks is costly in terms of the limiting bandwidth and increasing switching complexity. MPLS, OBS and OPS have been proposed as solutions to realizing an all-optical network. MPLS and OBS have the advantages of creating all-optical connections between nodes, but don't allow intermediate nodes to also use the wavelength. Additionally, optical switches are constantly being reconfigured to accommodate new connections. OPS can make switching decisions in the optical domain, but the technology is immature.

What's the fuss about... third-generation?

In precise terms, it provides packet switching capability allowing the existing networks to mimic the way in which data moves around the normal fixed internet. There is also the issue that 3G coverage is likely to be limited to the larger urban...

Peter Cochrane's Uncommon Sense: DIY v DIFM networks

Today we see commerce, creativity and productivity crippled by a lack of adequate road and rail transport compounded by no bandwidth to the home and office. So installing optical fibre is a straightforward proposition.

Peter Cochrane's Uncommon Sense: Analogue or digital?

In the military domain we have already gone down the route of modelling conflicts in great detail before we fire the first bullet and we have a reasonable surety of a win before a war even starts. When our machines are given the benefit of sensory...

Peter Cochrane's Uncommon Sense: Hype and Skype

The most basic and fundamental is constraint is restricting the number of hops between routers and switches connecting any two points. This is referred to as circuit switching. We are moving from a world of circuit switching to a world of packet...

Quocirca's Straight Talking: Say 'no' to walled gardens

Rather than allowing Vodafone users to simply log into their existing MSN (or other mainstream IM) account from their handset, the service will require the user to set up a second IM account with Vodafone and route all traffic through that.

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.
