Leading-Edge Consultancy Metanoia, Inc. and Global Semiconductor Leader and Technology Innovator Broadcom Illuminate Optical Ethernet Networks

The Ethernet services market worldwide will be $17B by 2011, and the equipment market, currently at ~$7.2 B, is projected to grow 17.5% CAGR until 2014. With such interest, it is imperative to have a clear industry-wide understanding of “optical Ethernet” -- which has been a subject of much confusion lately. For the industry’s benefit, experts from deep-dive consultancy, Metanoia, Inc., and global communications leader Broadcom are resolving this through their technology papers & webinars.

Mountain View, CA, March 27, 2010 --( Carriers worldwide are on a quest to deploy versatile, efficient, and cost-effective packet-based technologies to deliver next-gen revenue building services. These include enterprise applications such as video, voice, teleconferencing, critical software-as-a-service offerings,, VoIP and the like.

Metanoia, Inc. Principal Technologist, Vishal Sharma, said from his Mountain View office, “We have been seeing this TDM-to-packet network transformation in provider networks world-wide for some years now; whether it be AT&T & Verizon in the US, Telecom Italia & BT in Europe, or Reliance Communications & Singtel in Asia. This shift is fueled primarily by two trends: the advent of triple-play (voice, video, data) services for enterprise and residential customers, and, lately, the explosion in video and mobile data services, and the evolution in both packet- and transport-network equipment.”

The goal of the carrier, of course, is to offer manageable end-user data services with a measurable QoS (Quality-of-Service) at the minimum cost per bit, using the smallest footprint systems, with the simplest implementation that allows for service-level agreements, operational efficiency, and traffic scalability. This has lead to the emergence of two design principles: the lower the layer at which packet data is carried, the lower the cost, and fewer layers (simpler systems) mean less expensive systems, and, hence, lower cost. Thus, recent developments in both the Ethernet and optical spheres have been geared towards this goal.

Adding to this, Shahram Davari, Associate Director, Network Switching at Broadcom said, “In this regard, there have been rapid advancements to make packet technologies, such as IP and Ethernet, more “circuit-like”, and to make transport technologies and equipment more dynamic and, thus, “packet friendly.” These developments have lead, over the last few years, to the emergence of a mélange of terms: “optical Ethernet”, “metro optical Ethernet”, “packet-optical transport”, “Carrier Ethernet”, “metro Ethernet”, which are often used interchangeably, blurring the distinction between them, and leading to confusion in industry circles.”

The objective of these experts in their series of articles is to shed light on optical Ethernet.

They begin this exercise in their recent article on NASA Tech Briefs, titled “Demystifying Optical Ethernet Networks”, where they define the terms: optical Ethernet, Carrier Ethernet, and packet-optical transport, explain their relationships, and show how they all fit together in emerging optical Ethernet networks. (The need for such an exposition can be judged merely from the fact that the article was in the top 10 listings on Google, from over 2, 770,000 listings, for the term “optical Ethernet” (without quotes) within 4 short weeks of its publication.)

This is to be followed by other articles in this series that will go into exploring each of the components of optical Ethernet and the technology building blocks in more detail. The full technology paper can be downloaded from: MetanoiaInc_OpticalEthernet_TechPaper_20100321.pdf.
