To provide information to potential customers on the output from this EPSRC/DTI funded project
concerning resource management - making better use
of expensive communications and server resources in today's information
society.
In the last few years the Internet has experienced
phenomenal growth. Commercial companies now account for more than
half the users of the network and increasingly they are using
the Internet protocols in their internal networks. Demand for
network resources is outstripping availability. This raises questions
about how the finite resources in networks should be allocated.
A major problem is ensuring that critical business applications
receive appropriate resources so that they can operate reliably
and efficiently.
RAMS partners analysed the data traffic patterns
of applications in operational commercial networks that use the
Internet protocols. The programme then used the results of this
analysis to develop a network management system that will distribute
resources in such a way that key applications can receive priority
without impairing the performance of other applications.
As distributed applications become more crucial to corporate competitiveness, network congestion becomes a more serious issue. The project addressed this problem, but in a way that accounts for
commercial requirements from the outset, giving network
administrators the degree of visibility and control over their
installations that they demand.
RAMS examined the interaction between distributed applications and the network, and to developed a resource allocation management system which can be used to ensure that critical applications have the network resources they need to operate efficiently. This system operates by providing sources of network traffic information on the state of the network using standard network management protocols. Two methods of controlling the sources of network traffic were investigated: one method through the manipulation of the protocol stack software on individual machines, controlled to a resolution that affects the traffic injected into the network by different applications; the other approach involved controlling the application directly in order to change the volume of network traffic it generates.
The resource allocation management system will be
demonstrated by the development of a prototype.
