There's another company out there aiming to partner with network operators on CDN technology. VidScale (news), which until now has had mostly Asian customers, has now moved into the US cable MSO market with a win at Avail-TVN today. Avail-TVN will leverage the company's MedaWarp software to integrate both transparent caching and commercial CDN services into their AnyView services.
Several years ago, the CDN was on nearly every telco's to-do list - but the difference between the global scale of a content-provider-focused CDN like Akamai and the caching and traffic management needs of regionally focused last mile assets was largely glossed over. That fad faded a bit from the public eye (except at Level 3 and a few others like Tata), but there has been a lot of work going on behind the scenes since.
VidScale's product is another example of the line of thought that makes the CDN an integral part of the network rather than as an overlay service. Similar lines of attack have come from Alcatel-Lucent's Velocix platform and also from Edgecast's recent wholesale moves as well as its recent partnership with PeerApp.
VidScale aims to set itself apart via an active hardware agnosticism, federated transparent caching within the network, very tight integration of the twin focuses of delivering managed and unmanaged content, and a plug-in architecture for extensibility.
We will be hearing more about network operators and their CDN projects throughout 2012 I think, particularly from the mobile space as carriers position themselves to scale 4G properly.
