ccnGen: a high-speed generator of bidirectional CCN traffic using a programmable switch

Abstract

This paper designs ccnGen, which generates request-response bidirectional CCN traffic, using a programmable switch. A prototype implementation demonstrates that one pipeline of the switch ASIC generates Interest packets of 232 64-byte names randomly with a uniform distribution and another one replies to the Interest packets by sending Content Object packets with the requested names at 1.6 Tbps speed.
