Current computer networks are challenged by the overwhelming multiplication of available content and the increasing requirements of the content delivery applications. Content caching is already playing its role in content delivery solutions. In this paper we identify the parameters and conditions that affect the performance of content caching solutions and the improvement of the content delivery process.We evaluate caching solutions performing simulation under varying external conditions based on typical service provision considering user requests, content features and network conditions awareness. Based on the simulation results we then describe the mechanisms of a cache federation using various algorithms. We propose novel ways of multimedia data object identification and the exploitation of the network awareness, for further enhancing of the caching capabilities and related service provision.
