Abstract :
This paper proposes an extension to the standard subnet bandwidth manager (SBM). The extension controls the best effort traffic on the subnet to minimize its impact on the QoS of the RSVP (resource reservation protocol) flows. The extension is achieved by adding extra messages to the standard RSVP that enables the SBM to signal the hosts about the available bandwidth. The hosts then control the rate of best effort traffic accordingly to avoid excessive collisions on the subnet. The implementation of the proposed extension on a shared Ethernet LAN demonstrates the benefits of this extension
