3 Description Switch Schemes

ATM Forum Document Number: ATM Forum/98-0408 ************************************************************************************** Title: Overload based Explicit Rate Switch Schemes with MCR guarantees ************************************************************************************** Abstract: In this contribution, we present four overload based switch schemes which provide MCR guarantees. A typical explicit rate switch scheme monitors the load on a link and gives feedback to the sources. The overload factor is de ned ratio of rate of input to link capacity. The switch schemes proposed use the overload factor to calculate feedback rates. A dynamic queue control mechanism is used to control queues and achieve constant queuing delay at steady state. The algorithms proposed are studied and compared using di erent con gurations. ************************************************************************************** Source: Bobby Vandalore, Sonia Fahmy, Raj Jain, Rohit Goyal, Mukul Goyal The Ohio State University Department of Computer and Information Science Columbus, OH 43210-1277 Contact Phone: 614-292-3989, Fax: 614-292-2911 E-mail: fvandalor,[email protected] This presentation of this contribution is sponsored by NASA Lewis Research Center. ************************************************************************************** Date: February 1998 ************************************************************************************** Distribution: ATM Forum Technical Working Group Members (AF-TM) ************************************************************************************** Notice: This contribution has been prepared to assist the ATM Forum.
