The Design of Real-time Transmission

Abstract

Some network services, such as Vehicle tele-operations, remote monitor requires time critical services. The publish-subscribe architecture has been designed to provide message transmission task. The paper presents a publish-subscribe communication model with QoS parameter indicator. The fair scheduling strategy guarantees the real-time service. The implementation of real-time publish-subscribe communication protocol is built on the top of standard UDP stack. It offers practical advantages for applications with time-critical data flows, which can provide control of timing requirement and reliability.
