Real-time Traffic

Real-time traffic is traffic with some sort of hard or soft delay bound, presumably larger than the one-way no-load propagation delay. Such traffic can be said to be delay-intolerant. For voice or video traffic, a packet arriving after the time at which it is to be played back might as well have been lost. Fortunately, voice and video are alsoloss-tolerant, at least to a degree: a lost voice packet simply results in amomentaryvoicedropout;alostvideopacketmightresultinreplayofthepreviousvideoframe. Handling traffic that is both loss- and delay-intolerant is very difficult; we will not consider that case further. Much (but not all) real-time traffic is also rate-adaptive. For example, the online-video service hulu.com can send at resolutions of 288p, 360p, 480p and 720p, approximately corresponding to bandwidths of 480 kbps,700kbps,1Mbps,and2.5Mbps[2012data].

(Hulu transmissions, where the consequence of delay is a pause in the video replay rather than a loss, are not necessarily “real-time”; see 20.3.2 Streaming Video below.) As another example of rate-adaptiveness, the voice-grade audio-compression codec Opus (a successor to an earlier codec known as Speex) might normally be used at a 64 kbps rate, but supports a more-or-less continuous range of rates down to 8 kbps. While the lower rates have lower voice quality, they can be used as a fallback in the event that congestion prevents successful use of the 64 kbps rate. Generallyspeaking,rate-adaptivitynotwithstanding,real-timetrafficneedssufficientmanagementthatcongestionbecomesminimal.

The most definitive way to achieve this is via some sort of reservation or admissioncontrol mechanism, where new connections will not be accepted unless resources are available.
