摘要
In this paper, we propose an improved fault-tolerant routing algorithm for meshes with convex faults. By fully utilizing virtual channels of each class and properly enforcing routing constraints, the proposed scheme requires only two virtual channels per physical channel to ensure deadlock-free property in two-dimensional meshes. This is significant from both theoretical and practical points of view. Our distributed routing algorithm requires only local knowledge of faults and works correctly for any combination of convex faults. (C) 2002 Elsevier Science B.V. All rights reserved.
