A Video Delivery Method Using Available Bandwidth of Links with Buffers and Disks

Scheduling policies and methods are required to deliver videos through network structure since the videos are key contents, and they are continuous media, in order to design the networked multimedia systems. These systems allocate resources before video clips leave their servers for guaranteeing continuous play of the videos. The policies for achieving video delivery play an important role in sense of effective delivery. The method for utilizing the links is a momentous problem, since their capabilities are restricted, and extensions of their capabilities are a difficult issue. The policy shown in this paper is that available network bandwidth is used for delivering one video clip at once. The bandwidth of a link is exclusively used to deliver only one video clip. On the other hand, buffers and disks are established easier than the links. Moreover, some simulating results are shown. Then, the amount of buffer space is restricted, and disks are used for storing the video in temporal.
