在TB路由器、多服务开关平台和无线基站等高速通信应用中,数据缓冲与排队是常见的问题。这些问题通常使用FIFO等高速存储器来解决,但是对以服务为导向的IP网络需求的不断增长和对服务品质越来越严格的要求正在使这种情况发生变化。 由于这些网络承载了不断增长的音频、视频、压缩包和传统的数据,服务品质成为了系统和网络设计中新的关键问题。直到最近,短时数据缓冲的工作还一直是由传统的FIFO来控制,这里数据通常是暂时存储起来,以避免人 In high-speed communications applications such as TB routers, multiservice switch platforms and wireless base stations, data buffering and queuing are common issues. These problems are usually solved using high-speed memory such as FIFOs, but the growing demand for service-oriented IP networks and the need for ever-stricter service qualities are changing this situation. As these networks carry increasing amounts of audio, video, archive and legacy data, service quality has become a new critical issue in system and network design. Until recently, short-time data buffering has also been dominated by the traditional FIFO where data is usually stored temporarily to prevent people
