Multipath Transmission in Content Centric Networking Using a Probabilistic Ant-Routing Mechanism

Content Centric Networking (CCN) is a new networking paradigm that names pieces of content rather than network nodes. It promises more efficient transmissions due to in-network caching and easier realization of mobile and multihomed devices. However, in order to leverage multipath transmission for multihomed devices, routing and forwarding mechanisms are needed that support this functionality. In this paper, we present a probabilistic ant-routing mechanism that enables multipath transmissions for CCN nodes. Using an OMNeT++ based simulation model, we show that our routing mechanism can support transmissions of data streams over multiple links to achieve higher throughput than any single link could provide.
