Metro's Future Is Tied to Ethernet

Ethernet will rule metropolitan networks in the not-too-distant future, according to the May Light Research poll, The Future of the Metro.

At press time, 53 percent of 763 respondents to the poll said they think more Ethernet than Sonet will populate metro networks in five years' time.

This is no surprise. Industry observers increasingly view the metro space as key to the future of optical networking, since it's the locus of lucrative business services based on optical backbones. And Ethernet, in turn, is seen as the key to unlock these services.

"Optical Ethernet is a key strategy for us. It takes away the metro bottleneck," said Brian McFadden, president of the Metropolitan Optical division of Nortel Networks Corp. (NYSE/Toronto: NT) in an exclusive interview with Light Reading at Supercomm 2001 last week. "Ethernet is scalable, ubiquitous, and cost effective. It's going to help drive the buildout of more fiber in metro areas."

The growing importance of metro Ethernet could be seen at Supercomm, as a growing roster of vendors specializing in optical Ethernet paraded their wares -- including Atrica Inc., Lantern Communications Inc., and World Wide Packets Inc.

Metro Ethernet also is the theme of an emerging alliance of carriers and vendors expected to debut tomorrow (see Thoughts on Supercomm, and watch for a story here later today).

All of this isn't to say that Ethernet will be the only networking protocol in the metro space. Roughly 19 percent of respondents to Light Reading's poll said that more Sonet than Ethernet will prevail in the metro. And a growing cadre of companies -- like Corrigent Systems (see Corrigent Joins Metro Ethernet Mix) -- says Sonet management and protection capabilities are going to be key to all metro networks in the future, including those based on Ethernet.

Some respondents think future networks will contain about the same amount of Ethernet as Sonet (13 percent); or be something else altogether (9 percent).

Interestingly, 6 percent of respondents, a sizeable minority in any survey, are stumped about the look of future networks. While Ethernet is clearly believed to be the metro's future, it's not a given that there won't be a range of still-unforeseen changes to Ethernet as that trend evolves.- Mary Jander, Senior Editor, Light Reading

re: Metro's Future Is Tied to Ethernet
...if Ethernet is really going to absolutely shut out Sonet in the Metro, how come most market reports still have Ethernet at 10-20% of the total Metro market until 2005, with the bulk of it still going to Sonet-lite?

Just wondering, I am not saying Ethernet is not going to play a huge role in the Metro, I firmly believe it will.

re: Metro's Future Is Tied to Ethernet I would look at those numbers at a lower level of detail. Outside of the ILECs, Ethernet ports should outsell SONET in 5 years. But SONET ports are more expensive and could still generate more revenue. Additionally, Ethernet metro ports are starting from a base of zero.

re: Metro's Future Is Tied to Ethernet Just gave the report a quick once over, it seems to be a bit overly pessimistic for companies on the "outs" with LR, and a bit too optimistic for those on the "in"...

Gee, has anyone ever said that before?

My advice is to read hard, the numbers are there.

Overall, I give it a grade of A minus, and it is worth subscribing...not a bad start.

re: Metro's Future Is Tied to Ethernet ownstock: to which report are you referring? It sounds like you're talking about Optical Oracle, yet you're posting in a thread on a Metro Ethernet poll.

re: Metro's Future Is Tied to Ethernet I am looking for any type of numerical information regarding the Ethernet market today and in the future. Does anyone have any good suggestions as to where I can find this information?

re: Metro's Future Is Tied to Ethernet ...10 Gigabit Ethernet will have a profound impact on the networking market. It will deeply penetrate the market in 2003. MAN/WAN revenues are expected to grow over 2500% to 1.8 billion in 2003 and to over 3.6 billion in 2004. This growth will continue exponentially over the decade as Ethernet continues to scale upwards...
