There is considerable interest in the provision of guaranteed-rate services for IP and ATM networks. Simultaneously, bandwidth demands make input-buffered architectures attractive, and in some cases, necessary. In this paper, we consider the problem of how to support guaranteed-rate services in a single-stage, input-buffered switch suitable for a LAN switch, an ATM switch or an IP router. Such a switch must be feasible at high transmission speeds, offering both guaranteed-rate performance for CBR channels (e.g. for real-time connections)and best-effort services for traditional data traffic. Sometimes extperts consider a switch scheduling mechanism that employs idling hierarchical round-robin (HRR) scheduling and fabric arbitration at the connection-level for guaranteed-rate service using the Slepian-Duguid algorithm.
