We just came back from the Open Networking Summit (ONS ’15). The event was quite interesting, both in terms of the exhibit floor and the talks. There was good participation, albeit more on the vendor side than the customer side. My main impression is that SDN technologies and solutions are moving from testbeds and concepts…
Sedona is proud to demonstrate our work with Telefonica at the SDN Solutions Showcase taking place at the Open Networking Summit (ONS), June 16-18, in Santa Clara, CA. Sedona will be demonstrating its multilayer (L0-L3), multivendor control at Telefonica’s network, implementing converged operation of IP and optical equipment from Juniper, Cisco, Huawei, and Ciena. The…
Sedona has made the short list for Light Reading’s Leading Lights award set to take place June 8, 2015. Our NetFusion Discovery multilayer app platform made it to the finalists list under Best New Product category. Sedona has created the market’s first multivendor, mulitlayer control platform for the Optical and IP/MPLS layers (L0-L3) of core and metro…
This is a short version of a tutorial paper that will be presented at the ECOC’15 conference in September. The full paper and the presentation can be found here. We discuss the control architecture for multilayer, multivendor, and multidomain networks. In the past, coordination amongst nodes was assumed to be done with distributed control, using extensions…
The promise of multilayer restoration as a way to save roughly half the cost of an IP core network is well documented: for example, in a highly visible paper authored by Cisco, Telefonica, and Deutsche Telecom that was published in IEEE Communications magazine and an ALU (now Nokia) white paper. The purpose of this post it to…
OFC was very exciting this year with lots of exhibitors and visitors, and lots of creative ideas in talks and in products. Overall Impression Multilayer networking and centralized control (which is what SDN means at the end of the day) have been widely discussed at OFC. The value of multilayer control has now been validated…
Sedona Systems is featured in a major article by Light Reading. The piece, by Mitch Wagner, discusses Sedona’s unique multilayer, multivendor IP/MPLS – Optical orchestrating software and its value to network operators. The article also quotes analyst Michael Howard from Infonetics, saying that Sedona may be the first company to coordinate the management of the…
This presentation describes why a hybrid architecture that includes both centralized control and distributed control is a flexible solution. This hybrid approach leaves room for vendor expertise and innovation, while avoiding vendor lock-in.
This technical document explains why distributed control lacks the ability to optimally control networks with multiple transport domains or both IP/MPLS and Optical layers. The paper, authored by Ori Gerstel of Sedona and Victor Lopez of Telefonica, then proposes a practical architecture to fix these issues and experimentally demonstrate it over commercial IP and transport gear.
Sedona is participating in OFC 2015. Visit us in Booth 504 to see how we’re transforming networks with our multilayer applications.
