Lightpath-Level Protection Versus Connection-Level Protection for Carrier-Grade Ethernet in a Mixed-Line-Rate Telecom Network

Tags:
ethernet

Overview Ethernet is a success story in Local Area Networks (LAN). Efforts for extending its boundaries beyond LAN to the carriers' backbone networks are in progress. The paper studies the problem of designing reliable and cost-efficient high-rate (100 Gbit/s) carrier-grade Ethernet in a multi-line-rate telecom network under signal transmission-range constraints. Reliability is achieved using shared-path protection at two levels: Protection-at-Connection (PAC) level, or Protection-at-Lightpath (PAL) level.

Has Gigabit Ethernet come of age?

Circuit-switched technologies traditionally utilised by carriers are slow and expensive to maintain when compared to Gigabit Ethernet. Gigabit Ethernet is tempting carriers to use it in the MAN as it does not require the protocol conversion of...

Have we gone MAN overboard?

Nothing here, it would seem, to challenge the incumbent technologies, most notably Sonet/SDH (synchronous digital hierarchy), a transmission standard used by most of the world's carriers today. And while over half of all carrier equipment will...

AMD experiments make better chips

More than ever we are up against power constraints," Sander said. The silicon-on-insulator layer similarly prevents leakage by removing loose electrical carriers from the chip. In its first paper, AMD described how it achieved a 30 percent...

Even if this can be achieved within a contended service, the residual capacity for data will be badly compromised. One is the move towards IP from other kinds of digital transmission, another is the trend to take digital voice all the way to the...

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

On private networks - LAN, WAN or in the carrier's core - application performance can be assured using two distinct quality of service parameters: DiffServ and MPLS. Sometimes these are called Platinum, Gold, Silver and Bronze but some carriers are...

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.
