Augustus: a CCN router for programmable networks

Despite the considerable attention that the ICN paradigm received so far, its deployment has been hindered by the scale of upgrades required to the existing infrastructure. Software programmable networking frameworks would constitute a remarkable opportunity for ICN as they enable fast deployment of novel technologies on commodity hardware. However, a software ICN router implementation for commodity platforms guaranteeing adequate packet processing performance is not available yet. This paper introduces Augustus, a software architecture for ICN routers, and detail two implementations, stand-alone and modular, released as open-source code. We deployed both implementations on a state-of-the-art hardware platform and analyzed their per formance under different confgurations. Our analysis shows that with both implementations it is possible to achieve a throughput of approximately 10 Mpps, saturating 10Gbit/s links with packet as small as 100 bytes. However, to achieve such performance, routers must be carefully confgured to fully exploit the capabilities of the hardware platforms they run on.
