Enabling real-time TV services in CCN networks

International audienceDue to the growing importance that content sharing applications are experiencing in our everyday life, the emerging Content Centric Networking (CCN) paradigm represents the most attractive solution for driving the current host-based Internet system towards a novel architecture focused around the content-centric concept. Basically, the communication in CCN requires the adoption of only two types of messages, namely Interest and Data. A user may ask for a specific content by issuing an Interest, which is routed across the network towards nodes in posses of the required information, thus triggering them to reply with Data packets.
