Service Based Approach to Real-Time Control of the Video Distribution System in the Columbus Ground Segment

Abstract

This paper introduces a service-oriented approach for managing the Video Distribution System. The main focus lies on the service of delivering a video stream from source to destination rather than on configuring the affected devices. This service approach implements a more transparent user interface for management and uses automation of system functionalities which makes procedures faster and less error-prone than low-level configuration as it is today. Moreover, error handling can be organized more effectively using the service-oriented system design. Additionally, subsystem requirements and Service Level Agreements (SLA) are monitored for compliance which enables an overview of the stability and functionality of the subsystem.
