Server selection is an important problem in replicated server systems distributed over the Internet. In this paper, we study two server selection algorithms under a server-based framework we have developed. These algorithms utilize server load and network performance information collected through a shared passive measurement mechanism to determine the appropriate server for processing a client ...

This paper deals with multi-component machine repair model having provision of warm standby units and repair facility consisting of two heterogeneous servers (primary and secondary) to provide repair to the failed units. The failure of operating and standby units may occur individually or due to some common cause. The primary server may fail partially following full failure whereas secondary se...

A multi-server queueing system with two types of requests and preemptive priority one type is considered as a model cell cognitive radio under practical suggestions about the arrival flows. hysteresis strategy for server reservation suggested to mitigate effect interruption service low requests. Under arbitrarily fixed values sets thresholds defining this strategy, behavior described by level-d...
