What I found most interesting is the deployment model, which is based around Telcos (i.e. as opposed to VoD portals like Amazon or iTunes). The first generation of VoD services were target for the PC, however, the new generation is based on Set-Top-Boxes, which integrate better with the TV. The reason why ISPs are in a good position to provide this service is because the already have a relationship with the customer and thus, it becomes natural to provide users with a set-top-box which is ready for VoD. The set-top-box is given for free as long as the user subscribes for a given period of time (e.g. a year).

The first interesting part of the work is that it democratizes Content Distribution and ensures that anyone — not just those in position to pay a CDN– can enjoy the benefits of an Internet-broadcast service that amplifies your data whenever and wherever it is needed. With CCN, Content Distribution becomes a “public” service (in the European way) of the Internet. In a sense, P2P has done much of that, providing a public service which publishers can use to propagate their content to many users at very low cost. However, this has been done without taking ISPs into account and that causes various inefficiencies. Instead, CCN happens at the core of the ISP and thus it has more chances of succeeding. Nevertheless, there are already solutions out there for ISPs to deploy cache overlays and ISP-CDNs, thus, making content distribution more efficient for all. So far, whether an ISP deploys content-aware storage infrastructure or not has been an economic problem, and not so much a protocol problem.
