Abstract
PowerPoint Presentation on ITU-T G.1050 and TIA-921 made at ATIS Meeting on March 23, 2006 in Las Vegas, NV
Telecommunications Industry Association TR-30.3/06-05-011
Separate queue with preferential servicing, traffic grooming
Less constrained routing and distances
Unmanaged IP Network, Internet(Profile C)
Lower quality video and VoIP, signaling, transaction data (highly interactive)
Separate queue, drop priority
Constrained routing and distance
Transaction data, interactive
Less constrained routing and distances
Short transactions, bulk data (low loss)
Long queue, drop priority
Any route/path
Traditional Internet applications (default IP networks)
Separate queue (lowest priority)
Any route/path
ITU-T G.1050 and TIA-921 Test Profiles based on ITU-T Y1541
Different test profiles for different Service Level Agreements (SLAs)
Impairment Type Units Range (min to max)
One Way Latency ms 20 to 100 (regional) 20 to 300 (intercontinental)
Jitter (peak to peak) ms 0 to 50
Sequential Packet Loss ms Random loss only (except when link failure occurs)
Rate of Sequential Loss sec-1 Random loss only (except when link failure occurs)
Random Packet Loss % 0 to 0.05
Reordered Packets % 0 to 0.001
Profile A – Well-Managed Network Impairment Ranges • Y.1541 QoS Level – suitable for high quality video and VoIP• Most Service Providers will be supporting this SLA for IPTV
ITU-T G.1050 and TIA-921 Test Profiles based on ITU-T Y1541
Different test profiles for different Service Level Agreements (SLAs)
Impairment Type Units Range (min to max)
One Way Latency ms 50 to 200 (regional)50 to 400 (intercontinental)
Jitter (peak to peak) ms 0 to 150
Sequential Packet Loss ms 40 to 200
Rate of Sequential Loss sec-1 < 10-3
Random Packet Loss % 0 to 2
Reordered Packets % 0 to 0.01
Profile B – Partially-Managed Network Impairment Ranges •Y.1541 QoS Level – suitable for Lower quality video and VoIP
ITU-T G.1050 and TIA-921 Test Profiles based on ITU-T Y1541
Different test profiles for different Service Level Agreements (SLAs)
Impairment Type Units Range (min to max)
One Way Latency ms 50 to 800
Jitter (peak to peak) ms 0 to 500
Sequential Packet Loss ms 40 to 10,000
Rate of Sequential Loss sec-1 < 10-1
Random Packet Loss % 0 to 20
Reordered Packets % 0 to 0.1
Profile C – Un-Managed Network Impairment Ranges •Y.1541 QoS Level – Internet little or no guarantees
