To Cache or Not to Cache: The 3G Case

- Summary
- Metrics

Abstract

Recent studies have shown that in the wired broadband world, caching of HTTP objects results in substantial savings in network resources. What about cellular networks? This article examines the characteristics of HTTP traffic generated by millions of wireless users across one of the world's largest 3G cellular networks and explores the potential of forward caching. You can easily use the simple cost model provided here to determine the cost-benefit trade-offs for your own cellular network settings. This is the first large-scale caching analysis for cellular networks.
