Towards Differentiated Services for the Internet , Bay Networks Architecture Lab, November 25, 1997. Emphasis on scaling. Several issues on designing a DiffServ network. Was first submitted as Internet draft in November 1997 and resubmitted unchanged as informational RFC in 1999 to make it referable. Premium service completely relies on proper provisioning of the networks whereas Assured Services presents a buffer management approach together with proper provisioning.
Scalability is reached by moving most of the complexity to the edge of the network.
There are several very useful examples of how Bandwidth Broker can be used. Proposes a two-tier hierarchical framework for resource management. The inter-domain management must use a standardized protocol. This approach is similar to the current two-tier routing architecture with BGP as inter domain routing protocol. Describes a first implementation of the two-tier resource management.
