Multi-node cooperative transmission over Content Centric Networking

In this paper, we present our implementation and evaluation of multi-node transmission over Content Centric Networking, which is realized by CCNx project. As there are no client-server connections in CCN, it offers the possibility to transfer data from multiple nodes as well as multiple links in parallel. However, in the current strategy of CCNx, even if there are many nodes who store the video files the client needs, the CCNx may choose one node to transfer the resource at one point, resulting the waste of other links. Thus we try to split video files into fragments. Multi-nodes will cooperate together to transfer the fragments As there are more than one nodes transferring the different fragments at the same time, each link can be made fully used and the transfer performance can be improved in some ways.
