Abstract

This draft proposes a two-tier resource management model for differentiated services networks. Following the approach taken by the Internet routing architecture, we propose that bilateral service agreements are made for aggregate border-crossing traffic between neighboring administrative domains. We also propose that administrative domains individually make their own decision on strategies and protocols to use for internal resource management and QoS support, both to meet internal client needs and to fulfill external commitments. We sketch out one specific realization of this two-tier model by having a Bandwidth-Broker (BB) as the resource manager for each domain and a BB-to-BB protocol, equivalent to BGP in routing, for inter-domain resource management. We believe that this two-tier resource management model matches the direction of, and complement the work by, the diffserv effort. We also expect this two-tier model to scale well in the global, heterogeneous Internet. Note: This draft contains pictures that could not be included in the text version.
