• Reduce total cost of ownership

• End to end service level measurements


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 Studywww.nwfusion.com3 Forrester Researchwww.forrester.com

PROBLEM RESULT

40% of companies delay launching new applications due to network performance concerns2

Reduced business productivity

59% of companies simply add bandwidth to ensure application efficiency2 Increased network costs

55% of companies only identify some of their network traffic2

Reduced understanding of network behavior

Cost of application downtime and degradation is 13K per minute for an ERP application3

Lowered network performance can be costly

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

• 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
