Deadline-Based Scheduling in Support of Real-Time Data Delivery
Source: Reed Elsevier
Many applications running on the Internet require timely delivery of real-time data. Examples of real-time data include stock quote updates and stock trades in on-line trading, bids in an on-line auction, state updates in a distributed multi-player on-line game, time-sensitive business documents in electronic commerce applications, video and audio data in a video conference, and voice data in IP telephony. To ensure timely delivery of real-time data, Quality of Service (QoS) support at the transport network is required. Techniques for QoS support include fair queueing and buffer management at routers, integrated services and resource reservation, and differentiated services.
