Implementation of an efficient transport for real-time game applications on HFC cable networks

چکیده
On HFC cable networks, in order to develop a realtime game application, we face a design problem to efficiently transmit packets with reliability. This paper introduces the SCRA (server-based collision resolution and avoidance) scheme. SCRA is a reliable transport method using UDP for real-time applications on HFC networks. In this design, we first analyze the collision probability, and estimate the required throughput on an upstream contention channel. Then, we use SCRA to spread the packets from a large number of users to reduce the traffic burst and to maintain a stable throughput for the application. The simulation shows that SCRA achieves ideal transmission time and bandwidth utilization. We also give the formulae to derive the parameters for a specific real-time application using SCRA. Keywords—HFC cable networks, upstream channel, reliability, transport protocol, collision
