  3. Branch Office VPNs with IOS-based Managed Services Security With Cisco IOS Firewall & Intrusion Prevention System Routing With Cisco Enhanced Interior Gateway Routing Protocol Management With Cisco IP SLAs Corporate Intranet Local or Direct Dial ISP SP Converged IP/MPLS Network PE MPLS to IPsec/PE Remote Users/ Telecommuters Head Office VPN B Provider Networks Internet PE Cable/DSL/ISDN ISP Business Partner Remote Access Corporate Extranet

  4. SLAs for IP/MPLS Networks • Cisco IOS IP SLAs’ operations measure per VPN • Allows measurements from a PE to CE routers Cisco Exclusive SP Converged IP/MPLS Network P Router Measure Either CE–PE or CE–CE Links CRS-1 Enterprise Site 2 Enterprise Site 1 Measure Either CE–PE or CE–CE or PE-PE Links Service Provider: Improved and flexible SLA management Enterprises: Access to comprehensive SLA reports © 2003, Cisco Systems, Inc.

  5. Enterprise Premise Edge Service Provider Aggregation Edge Service Provider Core Access Enterprise Backbone Cisco IOS IP Service Level Agreement:A New Direction • Cisco solution that assures IP service levels, proactively verifies network operation, and accurately measures network performance • Comprehensive hardware support • Committed Cisco partner support • Cisco IOS Software, the world’s leading network infrastructure software Enterprise and Small Medium Business Service Providers Understand Network Performance & Ease Deployment Verify Service Levels Verify Outsourced SLAs Measure and provide SLAs Cisco IOS Software

  6. Cisco IOS IP SLAsUnderstanding IP Service Levels • Optimize IP business applications and services • Voice over IP, Video, and VPN • Reduce total cost of ownership • End to end service level measurements

  7. The Need for IP-Based Service Levels 1 2003 Infonetics Research Study “Cost of Enterprise Downtime” www.infonetics.com/services/green.shtml?2004/service.provider.and.user.plans.shtml 2 2003 Network World Application Performance Market Study www.nwfusion.com 3 Forrester Research www.forrester.com

  8. Measurements and Metrics Continuous Predictable Reliable Automated Intelligence Proactive Cisco IOS IP SLAs Benefits

  9. Assureapplication and service deployment Cisco IOS IP SLAs Life Cycle Understand network performance baseline Confidence to deploy new IP services and applications Baseline network performanceVerify network readiness for new services with Cisco IOS IP SLA capabilities. 2 1 • Quantify results • Reduce deployment time • Prove service and application differentiation • Verify service levels • Reduce network down time • Manage demand for the network Fine tune and optimize Ongoing measurements to understand behavior with proactive notification 3 4

  10. Cisco IOS IP SLAs Advantages • VPN • SLAs are essential to VPN services • Quality of Service (QoS)-based measurements • Revenue for differentiated services • Brings IP service customer confidence • VoIP • Demonstrate how VoIP is working • Deploy with confidence • Enhanced customer satisfaction • Metrics useful for trouble shooting & and reducing down time • Business Applications • Assure delivery with network performance • Meet business objectives with guaranteed service levels • Assure network quality of service • Reduce downtime Key Services Benefit from Cisco IOS IP SLA I II III

  11. Comprehensive Hardware Support Enterprise & Aggregation/Edge Core Cisco IOS Software Release 12.2S Cisco 12000 Series Cisco Catalyst 6500; Cisco 7600 Series Cisco 10000Series Cisco 4500Series Cisco 7300Series Cisco 7200 Series Access Cisco IOS Software Releases 12.3T and 12.4 Cisco 2900, 3550, & 3750 Series Cisco 7200 & 7300 Series Cisco 2600Series Cisco 3700Series Cisco 1700Series Cisco 800Series

  12. Cisco IOS IP SLAs Uses and Metrics * Currently available **Limited availability in 9/04; complete in CY’05

  13. CISCO IOS IP SLAs FOR VoIP

  14. IP SLA for Voice over IP • VoIP may be difficult to deploy when the network behavior is not well understood • Cisco IOS IP SLAs will verify network readiness and QoS • Measure critical performance for VoIP deployment • Real time warning of network performance degradation • IP SLA is universally available across Cisco IOS Software routers Standard jitter, Packet loss, latency measurements Voice quality score measurements Call setup measurements Hardware-based VoIP measurements

  15. A IP SLA WAN Measurements A IP SLA End to End Measurements Cisco IOS IP SLAs for VoIP • Voice quality measurements between any two network points on any path • Continuous, reliable, predictable performance monitoring • Cisco IOS IP SLAs thresholds and hop-by-hop details isolate problems IP SLA Network to Server Measurements PSTN IP WAN Branch Headquarters

  16. Cisco IOS IP SLAs VoIP Roadmap November 2003, Release 12.3(4)T VoIP Codec Simulations using Cisco IOS IP SLA active monitoring Voice Quality Scoring March 2003, Release 12.3(7)T New Threshold traps, one-way packet loss, jitter, latency and MOS

  17. CISCO IOS IP SLAs for IP/MPLS

  18. Cisco IOS IP SLAs ExampleUnited States, Service Provider • Jitter: telephony and multi-media conferencing • Packet Loss: telephony, multi-media conferencing, streaming media, low latency data • Delay: telephony, multi-media conferencing, streaming media

  19. VPN SLAs and Performance Measurement • Cisco IOS Software is an MPLS leader • How can SLAs be measured with a specific VPN? • Cisco IOS IP SLA operations are vrf-aware and measure an SLA per VPN • Allows measurements from a PE or multi-vrf CE router 10.10.10.1 10.11.10.1 (PE) 10.12.10.1 CEs with VRFs Red, Blue and Yellow.
