Re - Usable Veri cation Elements forHigh - Speed Transfer

Presently, many communication protocols are under development which are tailored to the eecient high-speed data transfer meeting diierent application-speciic requirements. Our approach concentrates on a framework which facilitates the formal veriication of the protocols. The framework supplies veriied and re-usable implications between predeened protocol and service speciication components. For the veriication of a speciic protocol, protocol, service and medium can be modelled as compositions of framework speciication components. The veriication corresponds to proving that the system of protocol and medium implies the service. This implication can be proven by combining component implications of the framework. We apply L. Lamport's Temporal Logic of Actions (TLA) and use a TLA speciication style supporting the compositional speciication of process systems and the inference of system properties from process properties.
