Toward terabyte-scale caching with SSD in a named data networking router

Named Data Networking (NDN) routers can cache previously forwarded Data packets, and those can be reused when a matching Interest packet arrives. Unlike traditional IP routers and HTTP caches that exist as separate devices, designing a scalable NDN router is a new challenge because it should perform fast forwarding and massive-scale caching at the same time. This paper proposes a design of an NDN router with unique forwarding and caching mechanisms featuring terabyte-scale caching with solid-state drives (SSD) while still forwarding packets at line speed.
