Abstract: Caching has long been employed in computer systems to improve performance at the expense of additional complexity in memory organisation and management. The coherence schemes developed for traditional large-scale systems (CC-NUMA) fail when applied to the vastness of today|s mobile internet. A quality of service (QoS) approach is ideally suited for a general-purpose internet cache coherence protocol, providing strong consistency when needed while permitting weaker consistency for less critical data. An inexpensive, QOS solution to internet cache coherence is presented, and an experimental framework is outlined to verify the potential of the proposed scheme as a viable coherence solution for general internet applications.

Keywords: cache memories; client-server systems; computer networks; quality of service; QoS; cache coherence protocols; internet cache coherence; mobile internet; mobile networks; simulation; caching; data duplication; high performance networking.
