Enhanced Transport Scheme for Broadband Traffic Management and Quality Services

Modern data communication integrates traffic to carry audio, data and video simultaneously, enabling networks to accommodate an increasingly complex set of data traffic. Broadband Integrated Services Digital Network (B-ISDN) supports all types of traffic, including still and full-motion image applications [1]. With increasing number of wireless users, multi-media transmission makes network traffic more congested and there is need for effective traffic management to profit data transmission. Though, personal computing facilitates easy manipulation and secured storage, the access and exchange of information in wireless communication requires fast interconnections for profitable resource-sharing. With congestion as major challenge in broadband communication, transmission of multimedia data frames results in traffic levels overwhelming the network medium. Technically, this paper proffers an integrated scheme - link-to-link rate-based traffic flow control as basic technique to maximise bandwidth utilization, whereby all communications provided on traffic adopts the economy of sharing. Notably, implementation of Asynchronous Transfer Mode (ATM) technology and associated techniques delivers appreciable improvement in service quality. Also, improved continuity of service as users move maximally outside coverage areas were evidenced and modified transport scheme provided for negotiable Quality of Service (QoS). With the scheme mathematically implemented in simulation techniques, overlapping network traffics were managed efficiently and allotted bandwidth highly optimized. The traffic flow control proposed scheme implemented Additive Increase Multiplicative Decrease (AIMD) algorithm on transmitted packets to improve service quality. Therefore, capacity maximization of bandwidth scarce resource was achieved for all integrated services.
