Next generation CATV networks with QoS guarantees
This paper is a research mainly on how to build a high efficiency cable network; we will discuss the "Advanced IEEE 802.14 up" stream channel access mode along with the Collision Resolution Protocol, and then bring up a series of brand-new solutions of better efficiency, which are "Conditional Blocking Ternary Tree (CBTT) Algorithm", "Probability P-persistence Transmission Rule", and "Virtual Contention Algorithm". Furthermore, it will introduce a Multi-Priority mode to enhance the Quality of Service (QoS) for the multimedia transmission. We will utilize these techniques to improve the existing inefficiency of the cable network transmission, which greatly enhances the bandwidth utilization of cable network, and relatively drops the cost and improves economic value. In the end, this paper will show the simulation results using the NIST ATM/HFC Network Simulator to prove the high efficiency obtained from using the techniques (Advanced IEEE 802.14) proposed in this paper.
