VoD SERVICES USING HIERARCHICAL STRUCTURE

In this paper we considered the method of describing the telecommunication system providing VoD services using hierarchical structure with optimization and security features. Today we have seen that many times, during the downloading process of various videos, there will be disturbance or hanging and failures due to the low bandwith and other technical problems. In this paper we are proposing some methodologies to remove such type of failures by using the concepts of optimization of bandwidth which describes the relationship between the structural elements at each hierarchical level of the multi-layer graph. Video Transferring is resource (like band-width) consuming task and it require an optimal configuration of the system. The proposed hierarchical structure makes it possible to consider the telecommunication system as a whole and avoid any failure in the local optimum when solving optimization problem as well as providing some security features. Also some techniques are proposed for band-width reduction.
