Design and analysis of multiprotocol networks with IP routers

The design and analysis of large-scale multiprotocol networks interconnected by IP (internet protocol) routers are discussed, and efficient methods for routine data traffic across heterogeneous networks are introduced. For the internet currently operated by Defense Communications Agency, the long-haul network uses dynamic adaptive routing, while other networks adopt different types of routing mechanisms, depending on their network protocols. A class of modern routing algorithms, such as deterministic routing and virtual circuit routing, are also studied to develop intelligent methods for computing the performance measures for the global internet and subnetworks. For each routing mechanism used in the internet, analytical and quasi-simulation methods for computing various network performance attributes have been devised for expert-system network design tools. The study is extended to the case where the performance attributes are evaluated for the global internet with combined routing algorithms
