A Two-Tier Resource Management Model for Differentiated Services Networks

This draft proposes a two-tier resource management model for different iated services networks. Following the approach taken by the Internet routing architecture, we propos e that bilateral service agreements are made for aggregate border-crossing traffic between neighboring administrative domains. We also propose that administrative domains indivi dually make their own decision on strategies and protocols to use for internal resource managem e t and QoS support, both to meet internal client needs and to fulfill external commitm ents.
