Efficient Bandwidth Management Using Embedded Network Processor for Quality Distribution of Multimedia Over Mobile Networks

Authors : R.Pandian , V.Ramachandran and P.Seethalakshmi

Abstract: The main objective of this study is to implement an embedded bandwidth manager using network processor to improve the quality distribution of multimedia streams to internet enabled mobile clients. In this paper the bandwidth requirement for each media stream in mobile applications is converted into channel time requirement for that stream. The embedded bandwidth manager allots for each stream a share of channel time depending on its requirement relative to other flows and the stream accordingly regulates its packet transmission. As bandwidth and traffic characteristics of various flows in the network change, the channel time proportion allotted to the individual streams by the bandwidth manager varies dynamically providing minimum bandwidth requirements for each stream. Utilizing the high performance parallel processing features of network processor, the admission control and dynamic bandwidth management functions are implemented on the Intel IXP1200 network processor simulator. The six micro engines with four hardware threads for each are utilized for the modules Ingress classification, flow establishment, flow teardown, flow renegotiation, packet generation and dispatching. As these modules are processed in parallel, the quality distribution of multimedia over mobile networks is enhanced.
