Less pain, most of the gain: incrementally deployable ICN

摘要: Information-Centric Networking (ICN) has seen a significant resurgence in recent years. ICN promises benefits to users and service providers along several dimensions (e.g., performance, security, mobility). These benefits, however, come at non-trivial cost as many proposals envision adding complexity the network by having routers serve content caches support nearest-replica routing. This paper is driven simple question of whether this additional justified if we can achieve these an incrementally deployable fashion. To end, use trace-driven simulations analyze quantitative attributed lower latency congestion). Somewhat surprisingly, find that pervasive caching routing are not fundamentally necessary---most performance be achieved with simpler architectures. We also discuss how qualitative mobility) without any changes network. Building on insights, present proof-of-concept design architecture.
