  24. Cisco AVVID Attributes • Open, standards-based • Rapid application deployment • Building Blocks Supporting Cisco AVVID • Distributed Architecture

  25. Domains of QoS ConsiderationStrong as Your Weakest Link Avoiding Loss, Delay, and Delay Variation (Jitter) CallManager CallManager Router Router WAN Multilayer Campus Multilayer Campus Campus Not as Critical“Initially” Must Be Switched WAN Edge “A Must” QoS Starts in the WAN WAN Backbone “A Must” Often Overlooked or Misunderstood

  26. Three Classes of QoS Tools Router VoIP 1 1 V V V 3 2 2 1 2 1 SNA 2 2 • Prioritization • Classification + Queuing • Slow Link Efficiency • Link Fragmentation and Interleave (LFI ) • Compression, Voice Activity Detection (VAD) • Traffic Shaping • Speed Mismatches Data 3 3 3 3

  27. Prioritization Tools “Protecting Voice from Data” Router VoIP (High) 1 1 V V V Data (Low) PQ 2 2 1 5 3 2 1 1 WAN Circuit Data (Low) WFQ 3 3 3 3 Data (Low) 4 4 4 4 QoS Queuing Tools IP RTP Priority (Point-to-Point Links + Frame Relay) IP to ATM QoS (Multiple VCs or CBWFQ within VC) Identifying and Giving Priority to Voice

  28. Slow-Link Efficiency Tools Fragmentation and InterleaveNot Needed on Links Greater than 768 kbps Before Elastic Traffic MTU Real-Time MTU 214-ms Serialization Delay for 1500-byte Frame at 56 kbps After Elastic MTU Elastic MTU Elastic MTU Real-Time MTU Solutions Point to Point Links—MLPPP with Fragmentation and Interleave Frame Relay—FRF.12 (Voice and Data Can Use Single PVC) ATM—(Voice and Data Need Separate VCs on Slow Links)

  29. Traffic Shaping—When and Why? Result: Buffering which Will Cause Delay and Eventually Dropped Packets 128 kbps 256 kbps T1 RemoteSites 512 kbps Frame Relay, ATM 768 kbps CentralSite T1 • 1. Central to Remote-Site Speed Mismatch • 2. To Avoid Remote to Central Site Over-Subscription • 3. To Prohibit Bursting above Committed Rate • What Are You Guaranteed Above Your Committed Rate?
