Abstract

The P-SHIM6 architecture provides ISP independence to IPv6 sites without compromising scalability. This architecture is based on a middle-box, the P-SHIM6, which manages the SHIM6 protocol exchange on behalf of the nodes of a site, which are configured with provider independent addresses. Incoming and outgoing packets are processed by the P-SHIM6 box, which can assign different locators to a given communication, either when it is started, or dynamically after the communication has been established. As a consequence, changes required for provider portability are minimized, and fine-grained Traffic Engineering can be enforced at the P-SHIM6 box, in addition to the fault tolerance support provided by SHIM6. This project has been supported by the RiNG project IST-2005-035167 and by the IMPROVISA project TSI2005-07384-C03-02. Publicado Document type: Part of book or chapter of book

Abstract

International audience; With the rapid size shrinking in electronic devices,radiation-induced soft-error has emerged as a major concern to the current circuit manufacturing. In this paper, we present a new error correction scheme based on the residue number arithmetic to cope with the single soft-error issue. The proposed technique called bidirectional redundant residue number system requires the redundant moduli to satisfy some constraints to achieve fast error correction. In this system, both the iterations for decoding the valid number and the error-correcting table that contains all combinations of erroneous digit, are not necessary. The detection and the diagnosis are simultaneously performed in plural parallel consistent-checking that has the capability of locating the corrupt digit. Finally, efficient pipeline architecture for the self-diagnosis decoder is detailed.
