Multimedia Network Service Environment Based on Distributed Virtual Network Management
Multimedia applications are generally based on continuous streams such as audios and videos, which are very dependent on time and space constraints. This dependency leads to the requirement of functional services that support processing and communication of the multimedia data in distributed environments. The functional services, therefore, need to acquire media-specific meta-data from the distributed environment in order to provide end-to-end services with proper Quality of Service (QoS) specifications. In this context, it is very important that distributed multimedia applications become network-aware by gathering and utilizing meta datasets from underlying network resources. DvNOC (Distributed virtual Network Operations Center) is originally devised for user-oriented virtual network management based on distributed network resources. In this paper, we have come up with the DvNOC framework adopted for multimedia applications. The proposed multimedia network service environment based on DvNOC incorporates the functionalities of meta-data gathering, sharing, abstracting, federating, etc., which is ultimately capable of having applications and/or end-users aware of the underlying network resource information associated with media-specific attributes.
