Hybrid Information-Centric Networking (hICN)


hicn is an open source implementation of Cisco's hICN. It includes a network stack, that implements ICN forwarding path in IPv6, and a transport stack that implements two main transport protocols and a socket API. The transport protocols provide one reliable transport service implementation and a real-time transport service for audio/video media.
