Abstract
The paper describes a protocol-level adaptation mechanism to enhance the performance of network service provisioning to clientele. In our model, a service provider (SP) maintains multiple protocol modules to exercise the infrastructure resources. Here, each protocol exhibits a certain degree of cost optimality (in terms of resource usage) in distinct operating regions of the network infrastructure. An example is the cost tradeoff between the 'goback-N' and 'selective repeat' based retransmission schemes for 'reliable data transfer' between end-points under various packet loss rates in the network. During run-time, the SP selects one of the protocol modules that can meet the client-requested service obligation under the prevailing resource-level operating conditions. Our model allows a 'dynamic switching' from one protocol module to another at run-time based on the changing network conditions. The overall goal is to offer a sustained access to the service with a resource-optimal and QoS-compliant service offering. The paper describes 'protocol switching' as an architectural foundation for building cost-effective network services
