Cyan Widens Its Ethernet View

Craig Matsumoto

NEW YORK -- Ethernet Expo Americas 2011 -- Cyan Inc. is introducing multivendor metro Ethernet, a long-awaited step that could help operators better adhere to service-level agreements (SLAs).

Cyan is making its announcement Monday and will show off the technology Tuesday and Wednesday at Light Reading's Ethernet Expo in New York.

A multivendor layout would let operators use Cyan's CyMS management software and CyPortal interface to track a service's performance as it passes through other vendors' gear. Operators can also set up protection paths on Ethernet rings (the International Telecommunication Union, Standardization Sector (ITU-T) G.8032 type) built of certain other vendors' gear.

The catch is that Cyan's multivendor view only works with gear from Cyan's partners: Accedian , Overture Networks Inc. and Telco Systems (BATM) -- and a couple of competitor boxes that Cyan isn't mentioning publicly. Cyan can't provision a service across partners' equipment yet, although that function is coming, says Frank Wiener, Cyan's vice president of marketing.

Why this matters
We've been asking Cyan about multivendor management for a couple of years now, and it's finally coming to life.

True, Cyan covers a limited swath of the network. But that can be useful in cases such as Ethernet rings. Typcially, a partner's box sits at an aggregation point and hands Cyan an Ethernet uplink. The multivendor management capabilities would let the operator see, from one screen, what's happening throughout that ring and that uplink point.

The operator could also replace those two boxes with just Cyan's. That might seem like a minus for Cyan's partners, but they're trading off that network spot in order to offer a cheaper and potentially more manageable Ethernet ring, which becomes an easier sale, Wiener says. "They might have 10 nodes on a ring, and one goes away. But they could get more design wins."

For more
Here's the thread we've followed on Cyan and its converged capabilities. Note that Cisco Systems Inc. (Nasdaq: CSCO) was talking about doing this stuff, too.

At Ethernet Expo, Cyan will also be showing off the latency-modeling tool we'd written about in June:


And buried in all this is the announcement of the Z22, a box to go further out to the edge. Cyan says they've been shipping it for a little while now.

When you talk to them, ask them what is special about what they are doing in comparison to what one might do on a platform like HP Openview (or whatever the name of that the product is).  If they are just supporting more than standard MIBs and traps, that would be good to know.  If they are doing alarm coorelation across products that would be good to know as well.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
