Service Differentiation for NoC-based Multimedia Applications

2015

International audience; As the communication on-chip evolves toward the global multi-service network, various applications with different service requirements have emerged. A key factor is the support services with a guaranteed quality. The differentiated service with double physical channels is seen as the key technology to achieve this goal. It is focused on the control of traffic and recognizing the need for aspects for the management plan achieved by the bandwidth broker. In this paper, a novel QoS architecture for multimedia application over NoC is proposed. The gains in latency and in resource are possible due to the simplicity of the NoC architecture.

A new Three Color Marker for TCP flows

2004

In Differentiated Services networks, packets may receive a different treatment according to their Differentiated Services Code Point (DSCP) label. As a consequence, packet marking schemes can be devised to differentiate packets belonging to a same TCP flow, with the goal of improving the experienced performance. This paper presents an extensive performance evaluation of a new adaptive packet marking scheme, which relies on three different service classes, provided by the DiffServ network. The scheme provides protection of vulnerable packets in the TCP flows and adaptivity through "probes" packets. The performance have been evaluted in a traffic scenario composed of TCP flows with different …
