Interval Routing Scheme (IRS) is a routing framework, which provides a compressed routing table for efficient routing. In this paper Multe-Node-Label Interval Routing Scheme (MNLIRS) is introduced, which extends IRS to support end-to-end fault-tolerant delivery. MNLIRE Routing has several key advantages: compressed routing table, simple routing algorithm, and ability to fault-tolerant routing. Such advantages are very vital for clusters with lots of nodes and links.
