A design of linear task set model for multimedia services in IP network

The purpose of this article is to design a multimedia streaming system with a complex structure as the one with a simple and basic work structure and realize system design that can enhance both expandability and portability based on that structure. To solve the problem that it is too complex and has low expandability, this study suggests a system design structure based on the LTS (Linear Task Set) model. Based on the simple, basic structure grounded on LTS structure, the study defines a consistent process and allows free structure alteration in the simple system structure according to the service purpose and demand. To secure independence and simplicity among components, the study defines a port channel object of a singleton structure and realizes design that can allow stream transmission and overall stream monitoring on the system for all ports with the port channel based on the mapping information of a component port. And based on this model, the paper suggests a component system model that can realize multimedia streaming service. © 2014 SERSC.
