Example text
QoS Toolset [View full size image] Packets or frames entering a network device must be analyzed to determine the treatment that they should be given. This analysis is referred to as classification. Classification is the first QoS function to occur for any given QoS policy, and it can occur repeatedly at various stages of policy enforcement. To reduce the requirement for detailed recursive classification, it generally is recommended that traffic types be classified as close to their sources as possible and that their packets be marked accordingly.
711 audio codec for voice, it has the same loss, delay, and delay-variation requirements as voicebut the traffic patterns of videoconferencing are radically different from those of voice. For example, videoconferencing traffic has varying packet sizes and extremely variable packet rates. These are illustrated in Figures 2-2 and 2-3. Figure 2-2.
However, the assured forwarding classes, as defined in RFC 2597, were intended for flows that could be subject to markdown and aggressive dropping of marked-down values. Marking down and aggressively dropping Call-Signaling could result in noticeable delay to dial tone (DDT) and lengthy call-setup times, both of which generally translate into poor user experiences. Therefore, the QoS Baseline changed the marking recommendation for Call-Signaling traffic to DSCP CS3 because Class-Selector code points, defined in RFC 2474, are not subject to such markdown and aggressive dropping as Assured Forwarding Per-Hop Behaviors are.
