Architecture and Network Management for Next-Generation Internet.
Abstract
The goal of this project was to identify candidate network architectures and network management strategies for the Next-Generation Internet (NGI). For NGI network architectures, we first identified a set of Quality of Service (QOS) and reliability objectives to key NGI applications. We then qualitatively analyzed several NGI candidate backbone architectures based on several criteria: internetworking with end sites that use different technologies; internetworking between backbone subnetworks; routing switching; resource management; service restoration; and network configuration. We then completed quantitative analysis of two specific WDM-based NGI backbone architectures (WDM alone and IP over WDM). We completed a detailed description of the function to be performed in the NGI backbone network and their relationship to one another. The comprehensive functional architecture that we have developed focuses on the case in which IP and WDM technologies are used in the inter-connected subnetworks. For NGI network management strategies, we developed integrate architectures for both the intra-domain and the inter-domain cases, with an emphasis on supporting QOS and survivability of key applications. We also developed a software architecture for an NGI intra-domain network system and specified the management interfaces between the subsystems using the CORBA Interface Definition Language (IDL).
