ABSTRACT

This chapter presents the performance metrics of and enabling technologies for integrated networking, caching and computing systems. In caching networking systems, the average content delivery latency experienced by end users is a major performance metric. Typically, there are three types of average latency considered in the literature. The first type is the average latency of delivering content to end users from clients closest network nodes such as routers that cache the requested content locally. The second type is the average latency of delivering content to end users from peer network nodes. The third type is the average latency of delivering content from the content origin. These three types of average latency collectively reflect the average latency incurred by content delivery in the network. For networking-caching computing integrated systems, CapEX is composed of the expenses of constructing base stations, radio network controller equipment, backhaul transmission equipment, core network equipment, caching and computing equipment installation in network nodes.
