Variable bit rate applications generate data in variant rates. It is very challenging for subscriber station to predict the amount of arriving data precisely. Although the existing method allows the subscriber station to adjust the reserved bandwidth via a bandwidth requests in each frame, it cannot avoid the risk of failing to satisfy the QoS requirements. Moreover, the unused bandwidth occurs in the current frame cannot be utilized by the existing bandwidth adjustment since the adjusted amount of bandwidth can be applied as early as in the next coming frame. The proposed scheme has provided a way for utilizing the unused bandwidth in the current frame itself. The objectives of this project is ,the same QoS guaranteed services are provided by maintaining the existing bandwidth reservation and the bandwidth utilization is improved by recycling the unused bandwidth
