  • We propose an in-network caching architecture using OpenFlow to coordinate caching decisions in the network. Our scheme, called CacheFlow, extends the cache-and-forward concept by moving contents closer to the clients hop-by-hop using TCP for sending requests and retrieving contents. As such, CacheFlow can be incrementally implemented and deployed in the real network. In this paper, we present a simulation study of several caching policies, including a random cache policy, a statically optimal cache placement policy and a new disk placement strategy that places popular contents at the "center" of the network. Experimental results show that simple in-network caching policies can be realized using today's technology to improve network performance.
