A network management prototype for information delivery and planning with quality of service guarantees

This paper describes two resource management algorithms that have been implemented in a network management system called MetaNet that supports information delivery and planning with quality of service (QoS) guarantees for military applications. The first algorithm deals with provisioning QoS for end-to-end communication services, called MetaNet Channels, with immediate/advance resource reservation and priority based resource preemption. The second algorithm processes queries on bandwidth available over a given time interval for potential channels between two hosts that may be in different networks. The paper also describes results from a set of experiments that were performed to assess the performance and scalability of the QoS provisioning algorithm implemented in a prototype MetaNet system
