Yo Mama is soooo fat that.....

oh yeah????


Well, you Mama is so ugly that.....

I love it.

Hey Yankee.....stop wasting your time interviewing the vendors!!!! Then again, everyone knows that you offer the best PR that money can buy so if you didn't rely on the vendors for your information then you'd be out of business!!!!

re: Report Stirs Ethernet vs Sonet Debate
AMEN!!!

Or maybe at least create a PR section of the report and you can put Yankee and RHK in there.

Here's a Tag Line:

re: Report Stirs Ethernet vs Sonet Debate
To Lightreading

please keep Yankee off this sight

This is suppossedly to be for intelligent forward thinking people...

It isn't about Ethernet V Sonet but the integration of Ethernet into the Broadband IP strategy of existing networks.

A lot of buzz words start happening like provisioning, mpls etc etc and if i was anymore specific the boys at Yanks would publish it

But then since I wasn't paying them for writing it maybe not.....

Ethernet isnt a solution for corporations with global private line network needs.

re: Report Stirs Ethernet vs Sonet Debate
I would like to share a few critical considerations before adopting the metro-ethernet
standard.

If the metro-ethernet is base on today' s pure ethernet implementation, there is no way it can
achieve that kind of protection and restoration scheme offered by SONET. This scheme is so important to justify carrier-class service which
primary dedicated to a voice-carrier network.

A maximum tolerence of 50 ms for any restoration
scheme will ultimately inhibit the adoption of ethernet.

It is impossible for ethernet to solve voice
carrier-class service requirement unless IEEE
802.3 working group modify ethernet so much to look like sonet. (With all the in-band signaling)
Prove me wrong.Anyone?

re: Report Stirs Ethernet vs Sonet Debate
It may look and act like SONET in some ways but it will be called Ethernet. People have decided it's easier to get there from the Ethernet base camp. If you can't beat 'em, join 'em.

re: Report Stirs Ethernet vs Sonet Debate
Of course itGÇÖs going to take some time GÇô it requires what is commonly referred to as business case. You see not that long ago you needed to build a business case in order for things to move ahead, then along came a big party where everybody said the f* with business cases I gonna get my piece before somebody else does.

Are we all so focused on instant billions that we canGÇÖt be a bit more patient? Geez!

The SONET v Ethernet debate is over already, weGÇÖre just waiting for the business case to mature. Last year you didnGÇÖt need a business case to convince somebody to buy into it, this year you do.

Why do you want to solve resiliency at layer 2?
Ethernet over Sonet, Ethernet over Lambda, or IEEE 802.17,... all of them offer sub-50 ms resiliency.

Just don't use Spanning Tree (not even its grand-son) and your problem is solved. :-)

re: Report Stirs Ethernet vs Sonet Debate
MMA asked the question;

What was the reason for the 50 ms restoration switching time requirement? Does anyone recall?

50ms restoration is key to support legacy TDM/voice networks. This kept calls (hundreds to thousands of them) from dropping and causing the Class 4/5 switch to melt down. There are probably a couple of other reasons, but maintaining calls (or Tandem Links) was the main reason.

This discussion thread is very interesting. Ethernet vs. SONET. From all of my reading the answer to this question seems to be RPR.

Any thoughts on this?

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
