This thesis focuses on the dynamic proxy framework named the Chek Proxy
Framework (CPF). The main objectives are to scale the existing Internet architecture
by conserving the backbone bandwidth, reducing server loads, and improving the
overall networking system performance, particularly the client receiving rate. These
were achieved by deploying application-level proxy services within the network, to
accelerate and customise the delivery of contents.
The CPF is based on the 3-tier distributed computing architecture with the client and
server residing at the ends of the respective networks. A dynamically appointed
middle-tier system, the Dynamic Application Proxy Server (DAPS) is created ondemand
and resides at the client-side network based on the designed clustering
policy. The uniqueness of CPF lies on the use of voluntary client machines, instead
of static and dedicated machines to host DAPS services created at runtime
