Why is QoS and Especially Delay and Delay Variation Important ? End-to-end delay budgets are a strict operator requirement RAN transport delay is a significant contributor to end-to-end delay
Delay variation (jitter) is also important in dimensioning playout buffersHybrid approaches can be used to mitigate and protect delay-sensitive traffic versus bulk, best effort Convergence and phase stability of packet-based sync and timing protocols depend on low delay and jitter effects on packet/timestamp arrivals Ultimately, to fully leverage the packet-based RAN a range of traffic types must be accommodated: legacy, sync, conversational, messaging, streaming, best effort, OAM, etc.
Minimizing packet loss, delay and delay variation for certain traffic flows is crucial29 | 7705 Service Aggregation Router | October 2007 All Rights Reserved Alcatel-Lucent 2007
