Realistic Storage of Pending Requests in Content-Centric Network Routers
Content-Centric Networking (CCN) is a novel network paradigm, which aims at moving from the traditional host-to-host network model to a client-to-content one. This shift brings many benefits but also leads a big challenge on the hardware technologies for implementing CCN nodes. For example the Pending Interest Table, one critical component in a CCN node, is involved in every CCN message forwarding process, and needs to be updated every time a packet comes in. The implementation of this table requires a memory that is fast for short access time and also large enough for storing the pending Interests.
