We present a method for maintaining Quality of Service parameters for Internet Web
Services by means of dynamic distributed execution and maintenance of networked applications.
While the architecture presented provides performance acceleration, it also enables management
and administration of the distributed components of the networked applications from a single
responsible point of origination. The method deploys a plurality of proxy servers within the
network. Clients are directed to one of the proxy servers using wide area load balancing
techniques. The proxy servers download programs from main servers and cache them in a local
store. These programs, in conjunction with data stored at cached servers, are used to execute
applications at the proxy server, eliminating the need for a client to communicate to a main server
to execute a networked application. Our architecture enables the content distribution paradigm
deployed for static images and streaming video to be extended to the domain of dynamic pages
and general web-based applications.
