Document “Schemata for Network Performance Characteristics” Work In Progress. Document Layout: 3. Base Schema Explain that definitive schemata is in RELAX-NG, with XML appendix from specific tool 3. 1 Description 3. 2 RELAX-NG Code 4. Extension Schema Explain that These Schemata MUST be used in conjunction with the NMWG Base Schema Example (as in how to doc) using characteristic/tool “foo” 4. 1 Description 4. 2 RELAX-NG Code 5. Extension Schemata for Current Characteristics and Tools 5. 1 Round Trip Delay 5. 2 TCP Achievable Bandwidth 5. 3 UDP Achievable Bandwidth 5. 4 Frame loss 5. 5 Frame re-ordering 5. 6 Bandwidth Utilisation 5. 7 ping 5. 8 iperf (TCP) 5. 9 traceroute 3 © 2006 Open Grid Forum NMWG OGF 19 Chapel Hill February 2007 R.

Schemata: History u NM-WG then focused on standardizing schemas for exchanging network measurements u Extended concept to n Requesting historical network measurements n Requesting measurements to be made on demand n Traps and Event Notification u NM-WG has Two sets of schemata: n v. 1: : Monolithic, straight mapping of “characteristics” doc n v. 2: : Framework: l Base schema - common components, types, topology l Add separate sub-schema for each characteristic and/or tool l Framework has extensibility to just about anything l Schema language: Relax-NG compact syntax 6 © 2006 Open Grid Forum NMWG OGF 19 Chapel Hill February 2007 R.
