Operators are increasingly embracing software-defined networking (SDN) across their networks, from data centres to wide-area networks (WANs) and the customer edge, as part of their automation journeys.
Analyst Sterling Perrin writes about the requirements and benefits of delivering automation in the carrier WAN, with a focus on the IP and optical layers andas the value of software-based coordination between the layers using SDN.
In this Light Reading Telecom Innovator's Showcase, Sedona Founder & CTO Ori Gerstel sat down with Ray Le Maistre, Light Reading's Editor-in-Chief. The two discussed Sedona's network and automation platform, NetFusion, and how NetFusion is used to speed up and get better accuracy in network mergers and migrations.
This white paper examines how the control hierarchy for SDN networks is converging toward a three-tier structure, with a service orchestrator, a network controller, and multiple domain controllers. The benefits are plenty, including faster innovation, a stable ecosystem of collaborating parties, and flexibility to replace building blocks with minimal effort and without vendor lock-in.
In this video, CTO Ori Gerstel sits down with Glenn Wellbrock, Verizon's director of optical transport planning, to discuss the practical challenges and significant value of introducing accurate discovery and automation into a Tier-1 service provider network.
In this SDxCentral DemoFriday video, Sedona’s Gal Afriat and Daniel Tardent demonstrate NetFusion, a hierarchical network controller developed by Sedona to support the realistic migration to automated service-aware networks.
Selecting the right IP/optical network controller is critical for end-to-end service delivery in a multi-layer, multi-vendor, multi-domain network. This technical brief goes over the most important questions we suggest service providers ask suppliers when determining whether the solution can truly deliver comprehensive, accurate visibility and control.
In this video, Sedona's CTO Ori Gerstel speaks about recent developments in IP/Optical network visibility and control with Light Reading Editor Ray Le Maistre. Ori highlights recent developments in Sedona’s NetFusion platform and demonstrates core features.
Without understanding the connectivity and dependencies between network layers, you are likely unaware of the wasted CapEx and OpEx spent on deploying, operating, maintaining, and troubleshooting the network. The Sedona NetFusion solution addresses these issues with products that focus on integrated discovery and control of the IP/MPLS and Optical layers.
In this video, we offer ten powerful use cases for Sedona’s NetFusion platform as reported by our customers. These use cases are enabled by NetFusion’s ability to automatically discover and map the connectivity and dependencies between the IP/MPLS and Optical network layers.
Our customers are experiencing a network revolution with a world of multi-layer, multi-vendor, multi-domain information at their fingertips. Using NetFusion’s discovery and visibility capabilities, they have reported 10 common use cases and identified why these solutions are critical to business.
The NetFusion Intelligence and Automation App Platform is the first control platform that converges the layers, automatically discovering multi-vendor, multi-domain topology and traffic for both Optical and IP/MPLS layers, as well as the cross-layer connections between them.
Based on a webinar with Light Reading and Nokia, this white paper provides a detailed look at the new SDN-based IP and optical integration renaissance, including the market drivers, technology enablers, primary applications and use cases, leading operator success stories, and work yet to be done.
This white paper describes the NetFusion Intelligence and Automation App Platform, which enables multivendor discovery of the Optical layer, IP/MPLS layer, and cross-connections between the two layers. The accompanying NetFusion Explorer UI enables you to visualize and explore this multi-layer network model in near real-time, showing optically-aware IP/MPLS routing and conversely, IP/MPLS-informed optical paths.
Heavy Reading recently hosted a webinar on “The SDN-Driven IP-Optical Renaissance.” The speakers were Sterling Perrin, senior analyst at Heavy Reading, Ori Gerstel, Sedona’s CTO and co-founder, and Steve Vogelsang, President and CTO of Nokia’s IP/Optical Business Group.
This paper focuses on requirements for the NBI of Optical domain controllers in a multilayer architecture. The NBI of the optical domain controller has four main functions: topology discovery, monitoring, provisioning, and path computation. These requirements generally apply to both DWDM and OTN systems, with the obvious omission of feasibility limitations that only apply to the DWDM layer.
This paper focuses on requirements for the NBI of IP/MPLS domain controllers in a multilayer architecture. The NBI of the IP/MPLS domain controller has four main functions: topology and traffic discovery, monitoring, provisioning, and simulations for what-if analysis.
In the third episode of our Sedona Sessions series, CTO Ori Gerstel explains why multi-layer control is pivotal to SDN deployment. Multi-layer control turns what is often perceived as a monumental and daunting task into a manageable, evolutionary process.
In this Heavy Reading-hosted webinar, speakers Sterling Perrin, a senior analyst at Heavy Reading, and our CTO and co-founder, Ori Gerstel discuss “The State of SDN Deployment and How Converged IP/Optical Control Can Shake it Up,”
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.
