Cyan Counts Latency

Cyan Optics Inc. is adding a latency modeler to its toolkit, giving operators a way to calculate the expected delay between two points.

It's part of the mobile backhaul announcement that the company made Monday. Cyan is also integrating cell-tower maps into its management system, so the latency modeler will be looking at the actual connections between boxes. (See Cyan Announces Backhaul Gear.)

"A lot is determined by the distance the light travels, and it turns out, we have all the information on the fibers -- the distances, the attributes -- and we know what services are connected to what fiber," says Frank Wiener, Cyan's vice president of business marketing.

The model calculates latency through the parts of a route that use equipment from Cyan or the other OEMs that its software can support -- which so far means Accedian and Overture Networks Inc.

The latency modeler is due to be available this summer.

Why this matters
As Long Term Evolution (LTE) advances, latency will become an even bigger deal in mobile circles. And latency is already a key toward capturing business in deep-pocketed financial networks.

Latency is easy to measure after the fact, but predictive tools are just starting to pop up. Arista Networks Inc. and Mellanox Technologies Ltd. (Nasdaq: MLNX) include latency modeling in their newer software packages, as consultant Nick Lippis of Lippis Enterprises notes in an email to Light Reading.

An Ixia (Nasdaq: XXIA) representative, pinged late Friday via email, suggested that the cable industry might have such tools, and that carriers such as Verizon Communications Inc. (NYSE: VZ) have probably developed their own latency modelers.

This also continues the theme of tools that could be interesting outside the context of Cyan's own gear. As Light Reading keeps pointing out, Cyan's tools show the potential (key word -- potential) for the industry to develop multilayer, multivendor management software. Latency could end up being an important enough factor for someone, not necessarily Cyan, to advance that concept.

You might think we pay too much attention to Cyan. If so, here's some ammo for your argument:

Wow i think Alcatel-lucent had thought ahead of this... their optical division had a product that would  read the data-logs from the existing network elements in the network and give the latency along with the route that would be available between two points.

re: Cyan Counts Latency

Cyan is a very old world network company with roots from AFC-Tellabs. The video of the CEO and what he was saying (or lack of intelligeint thought) shows they are struggling to find their networking space.


Another company destined for failure if it does not come up with something defensible and market driven. They may experience a little "latency" before they come out with something relevant.
