Along with Limelight Networks (News - Alert) and EdgeCast Networks, PeerApp, a provider of solutions for internet caching infrastructure, recently showcased its implementation of content service extension (CSE) architecture that has the capability to enable broadband operators to collaborate with internet service providers to efficiently deliver services over the network.

The Content Service Extension (CSE) is stated to be an architectural framework allowing integration of operator system and network resources into existing content delivery networks (CDNs) and OTT services. Operators who deploy their solutions over this architecture will get a chance to work on over-the-top value chain and monetize OTT content delivery along with retaining full control over their own network and system resources.

The PeerApp demonstration of the CSE architecture showed how a 4K video content can be taken into the home from the LimeLight CDN footprint and along the way activating operator caching and network QoS extension services in a controlled manner. The demonstration made use of PeerApp’s UltraBand cache and CSE controller platforms as well as Sandvine’s (News - Alert) Service Delivery Engine (SDE).

Don Bowman, chief technology officer at Sandvine, said, “Sandvine and PeerApp have jointly driven operator caching to improve subscribers’ quality of experience at more than 40 communications service providers globally. The power of network functions virtualization allows us to enable innovative content delivery use cases while leveraging industry standards, including PCMM. We are proud to join the Content Services Extension initiative and to contribute technology leadership to an open service delivery environment.”

David Sokolic, vice president of business development and marketing at PeerApp, added, “With this demonstration, we've shown that the possibility for establishing a very different content delivery model exists – one that does not rely on paid peering agreements. In order for OTT video services to scale to the level of traditional cable and satellite video distribution methods, while at the same time providing the quality and reliability that consumers expect, the content needs to reside at the edge of the operator's network. Unlike paid peering agreements, CSE enables the content to be delivered from within the operator's local access network. This gives the operator greater visibility and control over the traffic and also enables an end-to-end guarantee of quality.”
