  • Conference Proceeding: Performance Analysis of Single- and Multi-Channel Contention Resolution Algorithm for the DOCSIS MAC Protocol
    Seung-Eun Hong, Oh-Hyeong Kwon, Sung-Kyung Kim
    [show abstract] [hide abstract]
    ABSTRACT: Data-over-cable service interface specification (DOCSIS) MAC protocol is the de facto standard for hybrid fiber coax (HFC) network, and has also given leverage to IEEE 802.16 MAC protocol. The primary medium access control (MAC) function is contention resolution algorithm (CRA), called frame-based truncated binary exponential back-off (F-TBEB), for bandwidth requests from cable modems. The DOCSIS MAC is on the upgrade by introducing channel bonding concept in that the multiple channels can be combined together to get greater aggregate bandwidth. This paper provides a simple analytical model to compute the F-TBEB delay and throughput in single DOCSIS channel. Furthermore, we give two solutions to the problem of CRA on multiple channels and use the analytical model to determine which solution is superior.

  • Conference Proceeding: Considerations for VoIP Services in IEEE 802.16 Broadband Wireless Access Systems
    Seung-Eun Hong, Oh-Hyeong Kwon
    [show abstract] [hide abstract]
    ABSTRACT: IEEE 802.16 defines the air interface standard for fixed/mobile broadband wireless access (BWA) metropolitan area networks (MANs), which is expected to support quality of service (QoS) for real time application such as voice over IP (VoIP). However, three major technical problems that stand in the way are: 1) absence of MAC scheduling for supporting codecs with voice activity detector (VAD); 2) absence of mapping procedure between IEEE 802.16 service flow and network flow; 3) absence of efficient admission control for VoIP. This paper proposes two schemes, statistical UGS and UGS-rtPS combined scheduling, of MAC scheduling, addresses mapping RSVP FlowSpecs parameter into IEEE 802.16 QoS parameter, and devises simple admission control algorithm for VoIP services
