媒体访问控制(MAC)协议的设计对于高速、高性能的局域网和城域网络来说是最关键的方面，因为在这一级别做出的决策决定了这些网络的主要功能特征。文献中提出的大多数MAC协议都不适合多媒体应用，因为它们在设计时考虑了一种通用的业务类型。因此，对于它们设计的流量类型，它们的性能相当好，但对于具有不同特征的其他流量流，它们的性能很差。在本文中，我们提出了一种称为多媒体MAC的综合MAC协议(M-MAC)，它将不同的MAC协议集成到一个共享媒体网络中的混合协议中，以有效地适应具有不同特性和服务质量要求的各种类型的多媒体业务流，即恒定比特率业务、突发业务(比如可变比特率业务)和紧急消息(比如控制消息)。我们建立了一个数学框架来分析和评估我们的M-MAC协议，该协议涉及一个带假期的排队系统。我们将我们的M-MAC设计方法应用于波分复用网络，并对其在不同业务条件下的性能进行了评估。
The design of the medium-access control (MAC) protocol is the most crucial aspect for high-speed and high-performance local and metropolitan area networks, since the decisions made at this level determine the major functional characteristics of these networks. Most of the MAC protocols proposed in the literature are not suitable for multimedia applications, since they have been designed with one generic traffic type in mind. As a result, they perform quite well for the traffic types they have been designed for, but poorly for other traffic streams with different characteristics. In this paper, we propose an integrated MAC protocol called the Multimedia-MAC (M-MAC), which integrates different MAC protocols into a hybrid protocol in a shared-medium network to efficiently accommodate various types of multimedia traffic streams with different characteristics and quality-of-service demands, namely, a constant-bit-rate traffic, bursty traffic (say, variable-bit-rate traffic), and emergency messages (say, control messages). We have developed a mathematical framework for the analysis and performance evaluation of our M-MAC protocol, which involves a queueing system with vacation. We have applied our M-MAC design approach to a wavelength-division multiplexing network, and evaluated its performance under various traffic conditions.
