Abstract

In this paper we review local caching of TCP/IP flow context data in the link buffer or a comparable other local buffer. Such connection cache is supposed to be a straight-forward optimization strategy for look-ups of flow context data in a network processor environment. The connection cache can extend common table-based look-up schemes and also be implemented in SW. On the basis of simulations with different IP network traces, we show a significant decrease of average search times. Finally, well-suited cache and table sizes are determined, which can be used for a wide range of IP network systems.
