A Limited-Global Fault Information Model for Dynamic Routing in 2-D Meshes
In this paper, a fault-tolerant routing in 2-D meshes with dynamic faults is provided. It is based on an early work on minimal routing in 2-D meshes with static faults. Unlike many traditional models that assume all the nodes know global fault information, our approach is based on the concept of limited global fault information. First, a fault model called faulty block is used in which all faulty nodes in the system are contained in a set of disjoint faulty blocks. Then, the information of faulty block needs to be distributed to a limited number of nodes at the boundary lines of block to avoid a message entering a detour area. We study the limited distribution of fault information in a dynamic network where faults occur during a routing process. Our study shows that fault information can be distributed quickly to help the routing process. In addition, the performance of routing process degrades gracefully in such a dynamic system. PCS routing scheme used in this paper and its experime...
