ConteXtream Collaborates with Red Hat on OpenStack Orchestration of Carrier-SDN

ConteXtream is working with Red Hat to integrate OpenStack orchestration with ConteXtream’s software-defined networking (SDN) and network functions virtualization (NFV) fabric for carrier-SDN solutions.

Specifically, ConteXtream has integrated Red Hat Enterprise Linux OpenStack Platform with its ContexNet SDN fabric.

ConteXtream said this collaboration enables end customers to instantiate ContexNet nodes in the right places, servers and switches within the network, as well as to provision the correct parameters and key performance indicators (KPIs).

When used for NFV purposes, ContexNet leverages Red Hat Enterprise Linux OpenStack Platform to populate its distributed mapping system with relevant information regarding instantiation of Virtual Network Function Components (VNFCs) in the network. In addition, Red Hat Enterprise Linux OpenStack Platform can direct the right VNFCs to the right ContexNet network virtualization edge overlay nodes, whether they are host-based, top-of-rack based or a WAN edge nodes.

The companies plan to continue work on joint use cases in the areas of the collapsed virtualized packet core, IMS-SBC VoIP applications, and full wire speed software forwarding needed for high-touch chaining-balancing actions for service providers.


“SDN and NFV have significant potential for changing the economics of service provider networks, and we believe OpenStack will be a key enabler to making this a reality,” said Radhesh Balakrishnan, general manager, Virtualization and OpenStack, Red Hat. “Through this collaboration with ConteXtream, we are not only demonstrating new, real-world applications of SDN technology, but setting the foundation for Red Hat Enterprise Linux OpenStack Platform to become a core component of next-generation programmable networks.”

“SDN and NFV bring efficiencies and feature velocity to service providers based on new abstractions that separate network control from physical forwarding, network functions from physical junctions,” said Sharon Barkai, co-founder of ConteXtream. “ContexNet inline flow orchestration and Red Hat Enterprise Linux OpenStack Platform cloud orchestration provide the sound structure enabling the software-defined and subscriber-centric agility, flexibility, elasticity features to emerge in carrier class, carrier scale production deployments.”

Alcatel-Lucent to Supply ConteXtream’s Session Control to Telenor

Telenor Group awarded a three-year global frame agreement to Alcatel-Lucent to supply mobile Internet optimization for Telenor’s 2G, 3G and 4G networks in Europe and Asia.

The deployment will use ConteXtream’s Session Control to manage end-to-end sessions across the network, automatically directing video traffic to Opera's Skyfire based on rules or policies decided on by the operator.  Opera’sSkyfireRocket Controller and Optimizer optimizes video streams and web in real-time on a per device, user and session basis, thereby improving quality of experience, reducing bandwidth and increasing mobile network capacity.

Alcatel-Lucent is also providing its Velocix 7810 Transparent Caching to temporarily store popular content closer to subscribers, as well as its 9900 Wireless Network Guardian to monitor service quality and provide network analytics.

Alcatel-Lucent said the solution will help Telenor address the challenges caused by mobile users accessing over the top (OTT) video from sites like YouTube or Netflix.

  • ConteXtream creates a virtualized service abstraction layer, enabling a wireless service provider to more quickly add new applications and network services. ConteXtream’s Service Provider-SDN solution identifies and steers traffic to the specific subset of network functions needed to support each subscriber flow, enabling greater network efficiency, and providing improved network management and subscriber visibility. Existing network functions, as well as the ones being newly introduced, benefit from this deployment. They include content filtering, spam filtering, customized billing, distributed caching, video optimization, TCP optimization, ad insertion, and network and subscriber analytics. 
    In May 2013, ConteXtream announced that a Tier 1 mobile operator in the U.S. had selected its solution. 
     The company is based in Mountain View, California with R&D in Israel.
