1. 1 SIP Performance Benchmarking draft-poretsky-sip-bench-term-04.txt draft-poretsky-bmwg-sip-bench-meth-02.txt BMWG, IETF-70 Vancouver Dec 2007 Davids IIT Gurbani ALU Poretsky Next Point

2. 2 Motivation Problem Statement: –Service Providers are now deploying VoIP and Multimedia using the IETF developed Session Initiation Protocol (SIP). –Industry lacks common terminology for SIP performance benchmarks –SIP allows a wide range of configuration and operational conditions that can influence performance benchmark measurements. Goals: –Service Providers use the benchmarks to compare performance of RFC 3261 network devices –Vendors and others can use benchmarks to ensure performance claims are based on common terminology and methodology. –Benchmark metrics can be applied to make device deployment decisions for IETF SIP and 3GPP IMS networks

3. 3 Scope SUT SIP Server (DUT) SIP ALG /NAT Tester (Emulated Agents) Benchmark SIP Signaling Performance (not Associated Media). Terminology defines Performance benchmark metrics for black-box measurements of SIP networking devices Methodology describes how to measure the metrics for a DUT or SUT SIP Signaling

4. 4 Benchmarks Maximum Session Establishment Rate Maximum Registration Rate Maximum IM Rate Session Capacity Session attempt performance Session setup delay Session disconnect delay Standing sessions

5. 5 Revision Changes Terminology 3.3.14. Loop Detection Option 3.3.15. Forking Option Methodology 4.3 Maximum Session Attempt Rate with Loop Detection Enabled 4.4 Maximum Session Attempt Rate with Forking 4.5 Maximum Session Attempt Rate with Forking and Loop Detection Enabled 4.6 Maximum Session Attempt Rate with TLS Encrypted SIP 4.7 Maximum Session Attempt Rate with IPSec Encrypted SIP 4.9 Maximum Registration Rate 4.10 Maximum IM Rate 4.11 Maximum Presence Rate
