| Summary: | Widespread use of computer networks and the demanding needs of current
network applications and technology impose a challenge to use the bandwidths in an
efficient manner so as to solve the network congestion and server overloading
problems. Some past and on-going solutions such as server replications and caching
have been proposed to overcome these deficiencies. However, these solutions have
not been implemented in an economical and configuration-transparent manner.
Moreover, the problems of caching and disseminating real-time multimedia data in a
bandwidth-conservative manner have not been addressed.
In this thesis, a CHEK Proxy Framework (CPF) has been developed using a
proxy solution to address these problems. By caching, proxy has become a
traditional solution in reducing user-perceived latency and network resource
requirements in the network. CPF helps to create a middle-tier application platform
proxy transparently and dynamically in the client sub-network to execute the
sharable section of any server application codes. This is as the application proxy. Besides caching static web contents, this local application proxy helps to deliver
real-time multimedia data on behalf of the remote server with lower bandwidth and
better performance. CPF helps to minimize WAN connections while maximizing
LAN interactions by multiplexing and de-multiplexing client requests through to the
server via the proxy. As a result, the central server is made more reliable and
scalable.
The monitoring and management of the CHEK distributed objects is also
made easier through the use of the CHEK Management Console (CMC). CMC
displays the inter-relationships between the distributed objects and their status
information on a GUI-based control panel for ease of management.
With its dynamic and transparent features, software verslOrung and
maintenance problems are readily overcome. CPF has been shown to be useful in
most client/server applications, particularly those of broadcasting and collaborative
nature such as video broadcastings and chat systems. CPF solves the network
congestion and server overloading problems with the presence of a middle-tier proxy
application platform which is allocated in the client sub-network with no manual
configurations. |
