Abstract

A formal language for specifying and implementing multicast communication, named MSIL, comprises a set of constructs that are specific to multicast communication. The language provides semantic structures for repetitive, conditional, sequential, and parallel execution. It supports message passing, is extendible and domain independent. The language is flexible enough to be used for translating high-level multicasting requirements into abstractions, as well as implementing low-level systems supporting these requirements. MSIL can also be used as a command and communication language to control node behavior for multicast communication. The requirements, syntax and semantics of MSIL, together with the ontology for multicast communication are described. A selected set of high-level requirements, for multicast network management, is analyzed to determine the corresponding MSIL specifications. A simplified QoS Manager, capable of providing multicast QoS to a restricted wireless network, has been coded in MSIL to demonstrate its suitability for system development.
