ABSTRACT
This article presents information regarding alternative delivery systems (ADS). The clearest clustering among ADS approaches is into network or application-focused camps. Products in the network-centric camp operate at the packet layer and see all traffic. They can control. shape and/or accelerate traffic flow -up to and including the TCP layer. Some devices reach higher into the protocol stack using deep packet inspection, and make stateful decisions across all network traffic based upon network conditions. An example of such a stateful decision might be to ensure that a new and unknown traffic source is allocated a modest amount of bandwidth and is not allowed to adversely affect mission critical applications. Products and services in the application-centric camp are designed to improve the delivery of a limited set of applications, but with very high functionality. The application-centric ADS solutions are associated with a server and the limited number of applications running on that server, but they see all the traffic and users accessing the server.
