This work present the design for an enhanced network system based on CATV a
nd CSMA/CD. It is for real time and multimedia transmission. The Object-Ori
ented technique is also incorporated into State Chart to design the network
, referred to herein as OOSTD. In addition, the multimedia network is thoro
ughly analyzed and the system is simulated by queuing model and implemented
. The analysis and simulation results confirm that the throughput and delay
of MORENET system are better than the conventional CSMA/CD or multi-channe
l CSMA/CD network.
