HFC 망에서 트래픽의 종류에 따른 IEEE 802.14와 MCNS 의 MAC 성능비교
A comparison of MAC protocols IEEE802.14 vs MCNS MAC for HFC Networks Depending on Traffic Types.
초록
Bidirectional cable TV networks using HFC(Hybrid Fiber Coaxial) networks need MAC (Medium access control) protocols to have efficient access in upstream channels. In this paper, we have studied and evaluated several contention resolution algorithms and mapping of higher layer traffic described in IEEE 802.14 and MCNS (Multimedial Cable Network System) MAC protocols with respect to IP, ABR and CBR traffic types. IEEE 802.14 MAC protocol demonstrates better performance for transmitting ATM cells while the MCNS MAC protocols for the IP traffic.
