In-network caching of content is a popular technique for eliminating redundant traffic from the network and improve the performance of network applications. In this paper, the authors present a novel cooperative caching strategy to improve performance of in-network caches. Their cooperative scheme is composed of an admission policy for the incoming data and a content exchange protocol between neighbor network caches to improve the search zone. The admission policy enforces that a previously cached data is not unnecessary replicated in other caches, resulting in more space for new data. The content exchange protocol allows for exchange on cached data, increasing the hit rate for incoming requests.
