Multicast and Quality of Service Provisioning in Parallel Shared Memory Switches

Free registration required

Executive Summary

Growing demand for differentiated services and the proliferation of Internet multimedia applications requires not only faster switches/routers, but also the inclusion of guaranteed Qualities of Service (QoSs) and support for multicast traffic. Here, the authors introduce a Parallel Shared Memory (PSM) architecture that addresses these demands by offering both QoS guarantees and support for multicast traffic. It is well known that PSM architectures represent an effective approach for distributing the high-memory bandwidth requirement found in Output-Queued (OQ) switches, while maintaining their desirable performance attributes.
