What’s the difference between the challenges faced by Telecom service providers and cable operators in their high-capacity backbone and metro networks? Not much, actually. We learned this at the CableLabs Winter Conference in Orlando this week. The central problem is essentially the same: separate IP/MPLS and Optical network layers with little or no visibility between…
Our announcement about raising $13.6M in round B funding has attracted plenty of attention. It was kick started in a blog item by Marcin Hejka, Vice President of Intel Capital. Announcing Intel’s investment in three Israel companies, Sedona being one of them, Hejka wrote that Sedona, “Is improving the connectivity of the world’s networks and the efficiency…
In a recent interview, Google’s Head of Datacenter Fabric and Inter-DC Networking, Vijoy Pandey, urged service providers to stop waiting for SDN/NFV standards to emerge. Instead, he advised, “Just go ahead and build this stuff… start deploying a few things, and you’ll see the benefits right away.” Well, I couldn’t agree more. The words SDN and NFV have…
We went to OFC 2016 with very high expectations. After all, we were about to demonstrate in Anaheim, California, the world’s first multilayer, multivendor automatic restoration of a fiber cut. Nevertheless, we were overwhelmed by the responses of operators, vendors, and analysts. In our booth and outside it, multilayer control was a major theme in…
I will be discussing the requirements that multilayer control imposes on the northbound interface (NBI) of the Optical layer controller and the IP/MPLS layer controller. This unique perspective calls for some non-obvious requirements that have not been discussed so far in standard bodies (such as IETF and ONF) and open-source forums (such as ODL and…
