Título: Providing QoS over Advanced Switching
Detalle: The Advanced Switching Interconnect (ASI) is a new open standard fabric-interconnect technology for communications, storage and embedded environments, which provides the advanced features of existing proprietary fabrics in an open standard developed by the ASI Special Interest Group. The provision of quality of service (QoS) in computing and communication environments is currently the focus of much discussion and research in industry and academia. ASI provides some mechanisms that correctly used permit us to provide QoS. Specifically, we use virtual channels, traffic classes, the egress link scheduling, and the admission control mechanism. In this paper, we examine these mechanisms and explain both how to provide a differentiated treatment establishing a priority system, and how to provide QoS guarantee. Specifically, we are going to provide QoS based on minimum bandwidth and maximum latency requirements. A special discussion is given over to the possible implementations of the egress link scheduling of the AS elements to obtain the QoS required by the applications.
