The Need for IP-Based Service Levels

1 2003 Infonetics Research Study Cost of Enterprise Downtimewww.infonetics.com/services/green.shtml?2004/service.provider.and.user.plans.shtml2 2003 Network World Application Performance Market Studywww.nwfusion.com3

Forrester Researchwww.forrester.com

Lowered network

performance can be costly

Reduced understanding ofnetwork behavior

Increased network costs

Reduced businessproductivity

RESULT

59% of companies simply add bandwidth to ensureapplication efficiency2

55% of companies only identify some of theirnetwork traffic2

Cost of application downtime and degradation is

$13,000 per minute for an ERP application3

40% of companies delay launching newapplications due to network performanceconcerns2

IP SLA History

Used to be called RTR, renamed SAA in 12.0(5)T; we call itEngine 1.

New Engine 2 is a major code rewrite introduced initially in12.2(11)T, and now present in all 12.3 and later trains. Engine 2is faster and consumes less memory.

New CLI (Phase I) and enhanced trend accuracy for 12.3(14)T

release: IP SLA, but using Engine 2+.

Cisco IP SLAs Provider: What Equant Says

Cisco IOS IP SLAs is an efficient way for Equant toprovide end-to-end reporting for each class ofservice. Not only does it enable round-trip delaymeasurement, but it also measures packet loss rate

and jitter. For us, the fact that Cisco IOS IP SLAs isembedded in Cisco IOS Software and does notrequire any additional hardware to be deployed to

support such features was a critical benefit.

Without a measurement tool like Cisco IP SLAs,what do you base your networks measurementson? One big advantage is that IP SLAs is down atthe hardware and Cisco IOS Software levels,measuring things. You dont have to put in other

separate devices to measure the service quality.

Customer Deployment Example

Wachovia Corporation

GoalSupport convergence of data, voice and video

Improve reliability of automated teller machine(ATM) network

Retire aging protocols to reduce network deploymentand management costs

Solution

Cisco 7206 VXR routers and Cisco 12000Series routers

Cisco Catalyst6509 switches

A mix of Cisco 1700, 2600, 2800, 3600, and3700 series routers

ResultsTransitioned from Systems Network Architecture (SNA),data link switching (DLS), and other protocols to IP

Reduced ATM network-related outages by 50 percent

Built architecture for successful convergence of data,voice, and video

The Cisco 7206 VXR

routers fulfilled theirinitial purpose and haveallowed us to now usethem to take on newtasks. We left themright where they were

connected, addednew features, andimplemented the IP SLAcapability and VoIPgatekeeper features inCisco IOSSoftware.

It saved us millionsof dollars in newdeployments.

CISCO IOS IP SLAs for MPLS


22/30


IP SLAs -- MPLS Health Monitor

Automatically create and delete IP SLAs LSP ping

or LSP traceroute operations based on networktopology

Works on the MPLS L3 layer, under the IP layer.Discovers MPLS issues even when IP routing is

working ok.

Dramatically reduces troubleshooting time, andcost associated to maintenance of MPLS networks.

Other PEs are discovered using BGP next-hop, andoperations configured accordingly.

Requires 12.2(27)SBC and later.
