Abstract

This paper investigates the impact of large flows in Content Centric Networks (CCN). In CCN, routers have caches, and store all the data after forwarding. If large flows temporarily occupy a content cache, they may evict popular chunks from the cache, and it results in low cache hit ratio. We mathematically analyzed the amount of occupancy of a large flow in a cache, and realized that a few large flows can constitute a significant portion of a cache. Our simulation results showed that small flows experience cache hit ratio degradation as the number of large flows increases. Finally, we present that limiting the occupancy of large flows in a cache can effectively improve the cache hit ratios for small flows.
