Aggarwal & collaborators develop novel caching framework

Asst. Prof. Vaneet Aggarwal
Purdue IE Assistant Professor Vaneet Aggarwal and his collaborators have developed a novel caching framework with erasure code called functional caching, which uses erasure coded chunks in the cache.

Aggarwal, along with his collaborators at George Washington University and AT&T Research, developed an algorithm which optimizes caching and quantifies an upper bound on the mean service latency in closed-form for storage systems. Arbitrary chunk placement and service time distributions are formulated via the efficient heuristic algorithm. A simulation prototype, operated in an open-source cloud storage system, validates significant service latency reduction utilizing this caching method.
