Abstract
This paper proposes a new medium access control (MAC) protocol named CONRAD (CONvergence of Real-time And Data services) for a passive-star based single-hop WDM local lightwave network which efficiently supports services with tight delay constraints, i.e. real-time traffic, and best-effort services, i.e. data traffic, directly in the optical layer. The integration of both service types in a packet-switched environment is primarily achieved by combining two different reservation schemes on the control channel, instead of applying conventional priority strategies or circuit-switched approaches. Thereby, a significant improvement of the access delay balance between real-time and data transmission may be obtained, while the system achieves high throughputs.
本文针对无源星型单跳WDM本地光波网络提出了一种新的介质访问控制(MAC)协议CONRAD (CONvergence of Real-time And Data services),该协议可直接在光层有效地支持具有严格延迟约束的业务,即实时业务和最佳努力业务,即数据业务。在分组交换环境中,这两种服务类型的集成主要是通过在控制通道上组合两种不同的保留方案来实现的,而不是应用传统的优先级策略或电路交换方法。因此,在实现高吞吐量的同时,可以显著改善实时和数据传输之间的访问延迟平衡。
