Cloud based Dynamically Provisioned Multimedia Delivery: An Elastic Video Endpoint

摘要

Content Delivery Networks are commonplace in today's Internet and are an important technique in the distribution of multimedia content to the plethora of Internet Protocol enabled devices. However, it has been recognised that current networks are many times over provisioned server side for peak demand and therefore greatly under utilised at other times. The emergence of cloud computing as a commercial reality has created the opportunity where content delivery networks can leverage the resources of existing cloud providers to increase capacity when required. In this paper, we propose an Elastic Video Endpoint (EVE), a virtualised multimedia distribution resource, which can utilise cloud resources to dynamically provision capacity in real time. Initial results have shown that the system can respond to increased load and provide extra bandwidth capacity on demand.
