Performance-based routing
نویسندگان
چکیده
In many-server systems with heterogeneous servers, the Fastest-Server-First (FSF) policy is known for its excellent performance. However, when service rates are unknown and/or time-varying, implementing the FSF policy is not straightforward. We thus propose a routing algorithm, Performance-Based Routing, that approximates the FSF policy: servers are ranked in a dynamic list, where the shorter the actual service times that a server exhibits – the closer the server is to the head of the list; a customer is then routed to the lowest-index (highest-in-the-list) idle server. It is argued that the algorithm is asymptotically equivalent to FSF.

متن کاملReliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)
Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...
