2 Cisco IOS IP Service Level Agreements Presentation Agenda Overview Business Drivers Benefits Cisco IOS IP Service Level Agreements (SLAs) for VoIP New Features for MPLS Partners Roadmap 2

3 Leverage Cisco IOS Software for SLAs Cisco solution assures IP service levels, proactively verifies network operation, and accurately measures network performance Comprehensive hardware support Committed Cisco partner support Cisco IOS Software is the world s leading network infrastructure software Enterprise and Small/Medium Business Service Providers Understand Network Performance and Ease Deployment Verify Service Levels Verify Outsourced SLAs Measure and Provide SLAs Access Enterprise Backbone Enterprise Premise Edge Service Provider Aggregation Edge Service Provider Core Cisco IOS Software 3

4 Understanding 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 4

5 The Need for IP-Based Service Levels PROBLEM 40% of companies delay launching new applications due to network performance concerns 2 59% of companies simply add bandwidth to ensure application efficiency 2 RESULT Reduced business productivity Increased network costs 55% of companies only identify some of their network traffic 2 Reduced understanding of network behavior Cost of application downtime and degradation is $13,000 per minute for an ERP application 3 Lowered network performance can be costly Infonetics Research Study Cost of Enterprise Downtime Network World Application Performance Market Study 3 Forrester Research 5

6 Benefits OPTIMIZED APPLICATIONS & SERVICES Performance visibility Prove service levels Enhance Customer satisfaction Enhance acceptance of businesscritical services REDUCED TOTAL COST OF OWNERSHIP AND OpEx Reduce deployment time Lower mean time to restore and downtime Proactive identification of issues enforces higher reliability Continuous Predictable Reliable Measurements and Metrics Automated Intelligence Proactive 6

7 Lifecycle BASELINE NETWORK PERFORMANCE Verify Network Readiness for New Services with Cisco IOS IP SLAs Capabilities 2 UNDERSTAND NETWORK PERFORMANCE BASELINE Confidence to Deploy New IP Services and Applications QUANTIFY RESULTS Reduce deployment time Prove service and application differentiation Verify service levels Reduce network downtime Manage demand for the network ASSURE APPLICATION AND SERVICE DEPLOYMENT FINE-TUNE AND OPTIMIZE Ongoing Measurements to Understand Behavior with Proactive Notification 7

8 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 I II III 8

9 Comprehensive Hardware Support Enterprise & Aggregation/Edge Core Cisco IOS Software Release 12.2S Cisco 7200 Series Cisco 7300 Series Cisco Series Cisco Catalyst 6500; Cisco 7600 Series Cisco CRS-1 (Future) Cisco Series Access Cisco IOS Software Releases 12.3T and 12.4 Cisco 800 Series Cisco 1700 Series Cisco 2600 Series Cisco 3700 Series Cisco 7200 & 7300 Series Cisco 2900, 3550, & 3750 Series 9

10 Uses and Metrics *DATA TRAFFIC *VoIP *SERVICE LEVEL AGREEMENT *AVAILABILITY **STREAMING VIDEO REQUIREMENT Minimize delay, packet loss Verify Quality of Service (QoS) Minimize delay, packet loss, jitter Measure delay, packet loss, jitter One-way Connectivity testing Minimize delay, packet loss IP SLAs MEASURMENT Jitter Packet loss Latency per QoS Jitter Packet loss Latency MOS Voice Quality Score Jitter Packet loss Latency One-way Enhanced accuracy NTP Connectivity tests to IP devices Jitter Packet loss Latency * Currently Available **Limited Availability; Complete in CY 05 10

11 CISCO IOS IP SLAs IS AN EFFICIENT WAY FOR EQUANT TO PROVIDE END-TO-END REPORTING FOR EACH CLASS OF SERVICE. NOT ONLY DOES IT ENABLE ROUND-TRIP DELAY MEASUREMENT, BUT IT ALSO MEASURES PACKET LOSS RATE AND JITTER. FOR US, THE FACT THAT CISCO IOS IP SLAs IS EMBEDDED IN CISCO IOS SOFTWARE AND DOES NOT REQUIRE ANY ADDITIONAL HARDWARE TO BE DEPLOYED TO SUPPORT SUCH FEATURES WAS A CRITICAL BENEFIT.

12 WITHOUT A MEASUREMENT TOOL LIKE CISCO IP SLAs, WHAT DO YOU BASE YOUR NETWORK S MEASUREMENTS ON? ONE BIG ADVANTAGE IS THAT IP SLAs IS DOWN AT THE HARDWARE AND CISCO IOS SOFTWARE LEVELS, MEASURING THINGS. YOU DO NOT HAVE TO PUT IN OTHER SEPARATE DEVICES TO MEASURE THE SERVICE QUALITY.

13 CISCO IOS IP SLAs FOR VoIP 13

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

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

16 for VoIP Features November 2003, Release 12.3(4)T VoIP Codec Simulations Mean Opinion Score (MOS) Voice Quality Scoring March 2003, Release 12.3(7)T New threshold traps, one-way packet loss, jitter, latency, and MOS Q1CY 05, Release 12.3(14)T H323 and SIP Post Dial Delay, Gatekeeper delays 16

17 CISCO IOS IP SLAs NEW FEATURES 17

18 Product Update Multi-operation Scheduler Availability: Releases 12.3(8)T and 12.2(25)S Schedule Groups of measurements, increased scalability Enhanced Accuracy Availability: Release 12.3(14)T Q1CY microsecond accuracy granularity Random Scheduler Availability: Release 12.3(14)T Q1CY 05 Randomly schedule active measurements New IP SLAs CLI Availability: Release 12.3(14)T Ease of use new configuration CLI 18

19 CISCO IOS IP SLAs FOR MPLS 19

20 Example United States, Service Provider IP CLASS OF SERVICE ONE-WAY DELAY THROUGHPUT JITTER QoS BANDWIDTH PER AAPP Priority Voice Traffic < 80 ms Packet loss < 5% less < 35 ms Max 75% Real-Time Traffic Video < 80 ms Packet loss < 3% 60% Priority Data Traffic < 100 ms Packet loss < 2% 30% Best Effort Traffic No target No target No target 10% Jitter: telephony and multi-media conferencing Packet Loss: telephony, multi-media conferencing, streaming media, low latency data Delay: telephony, multi-media conferencing, streaming media 20

21 VPN SLAs and Performance Measurement Cisco IOS Software is a leader in MPLS How to measure an SLA within a specific VPN? operations are vrf-aware and measure an SLA per VPN Allows measurements from a PE or multi-vrf CE router Releases 12.2(2)T, 12.2(20)S, and 12.0(26)S CEs with VRFs Red, Blue and Yellow.
