| With the propel of "Triple-network convergence" by the states in recent years,the fiber backbone network is basically achieved by now,and the last 100 hundred meters’distance comes to the bottleneck between local area network(LAN)and the backbone network.HINOC(High performance Network over Coax)access technology,because of its advantages of high access speed,QoS support and good compatibility with the old television network,has undergone a rapid development.This thesis focus on the MAC layer protocol of HINOC system and introduce this protocol in detail,elaborating the design of the HINOC MAC layer protocol and the mechanisms of the realization of this protocol on the platform of NS2.By analysis of the underlying C++code,the main frame structure,timer,data transceiver process and components elaborated,we completed the simulation platform structs of HINOC protocol of the MAC layer and the TDD/TDMA mechanism based on reservation in the ideal case.we realize that HINOC protocol has a reliable data transmission capacity. |
