response times but for many different metrics across the platform, such as cache hit rates and network resource utilization. An added benefit to some of this work is
energy efficiency for example, kernel and other software optimizations enable greater capacity and more traffic served with fewer machines. We will explore these principles further as we examine each of the the Akamai delivery networks in greater detail in the next sections. In Section 5 and Section 6 we outline specific challenges and solutions in the design of content,
streaming media, and application delivery networks, and look at the characteristics
of the transport systems, which differ for each of the delivery networks In Section 7, we provide details on the generic system components that are shared among the Akamai delivery networks, such
as the edge server platform, the mapping system, the communications
and control system, and the data collection and analysis system.
