passive port mirror, netflow on routers, IPSLA, customers maximize their hardware investment while obtaining full end-to-end network visibility.

• Is NetQoS a reporting solution?• NetQoS is more than just a reporting solution. We help executives and managers make better

infrastructure investment decisions, resolve problems faster by root, cause analysis, provide visibility to reduce network costs and troubleshoot. The integrated end-to-end solution further maximizes the existing Cisco technologies without additional agents and probes.

FAQs


maximizes the existing Cisco technologies without additional agents and probes.

• Who are your target customers?• Large enterprises. We have over 220 companies from the Fortune 1000/Global 500 list.

• How does NetQoS help my customer?• NetQoS leverages on customers existing investments by utilizing technologies such as NetFlow,

IPSLA, CBQoS, & WAAS without the need for expensive probes or agents to be deployed at remote sites. NetQoS provides greater visibility and end-to-end performance to help make more informed infrastructure investments, resolve problems faster, and save costs.

• What is NetQoS’ relationship to Cisco?• NetQoS is a Cisco Technology Developer Partner. NetQoS technology is now embedded as

part of the Cisco WAE IOS and on the NAM blade Q4 ‘08.

• My customer has Cisco WAAS Central Manager, do I need to buy NetQoS?• The central manager and NetQoS are used for different purposes. The CMS is used for

configuration and basic reporting. NetQoS SuperAgent provides baseline reporting across the all the enterprise WAAS links for a year to provide trending and true end-user response time experience. The NetQoS reporting allows more flexible reporting with pre and post optimization comparisons and greater WAN segment breakdown to identify performance issues.

FAQs


optimization comparisons and greater WAN segment breakdown to identify performance issues.

• Does NetQoS only provide reporting for WAAS?• SuperAgent reports on WAAS data as one performance metric. However SuperAgent is

designed to solve complete end-to-end performance i.e. from the remote user, WAN segment, server segment, and even multi-tier servers and load balancer performance analysis.

• Other NetQoS products utilize data metrics to give complete visibility for the data center that compliments the management of WAAS.

• Is the solution sold as software or hardware?• NetQoS comes bundled as a server appliance solution inclusive of the software.

• The Cisco WAN Optimization Enterprise Architecture Board (EAB) launched a new website that includes NetQoS.

• The WAN optimization EAB used NetQoS products to baseline performance before deploying optimization and to quantify the improvements after optimization.

• Further, the WAN optimization EAB used NetQoS products to understand the implications of enabling Cisco technologies such as NetFlow, IP SLA, CBQoS, NBAR, and several others.

Customer Story

• Fast-growing Australia bank with 30-35 new branches per year

• Hub and spoke network with many branches in small communities

• Frequently rolling out new applications – further straining bandwidth


• Frequently rolling out new applications – further straining bandwidth

• Highly cost-conscious and profit-driven, but…• Network costs are very expensive

• 128k links at many community branches

The Challenges

• When deploying new applications IT discovered slow performance at some branches

• Planning to strategically roll out VoIP• Implementing advanced QoS policies to

prioritize traffic• Historically relied on SNMP statistics for

capacity planning and troubleshooting


• Historically relied on SNMP statistics for capacity planning and troubleshooting • Only utilization and availability• Wanted to know Who, What, and When

…deployed NetQoS ReporterAnalyzer for NetFlow traffic analysis

The Results

• Soon after deployment IT received a complaint about slow performance at a branch office

• ReporterAnalyzer showed that a software distribution application was consuming the link—


The Results

• IT drilled down on the host and conversation details

• Found the specific, un-throttled software distribution server and application at fault

• The problem was quickly and permanently solved


The Results

• NetQoS ReporterAnalyzer makes possible an initiative to continuously review HTTP traffic throughout branch networks

• IT schedules weekly Custom Reports to examine HTTP usage by host and conversation


HTTP usage by host and conversation

• Provides detailed lists of client PCs that contribute to link congestion

The Results

• Enterprise-wide visibility into traffic that consumes bandwidth• Hundreds of branches• ~900 network links

• Avoiding unnecessary WAN costs• Mitigating risks from VoIP deployment


• Mitigating risks from VoIP deployment• Determine VoIP’s impact on network performance

• Solving problems faster• Enables IT to be more proactive

and help the branches use the network more efficiently

• Validating that QoS policies work

Device Availability and Utilization

Utilization Is a Poor Proxy

• Should this circuit be upgraded?


• How about now?

Good Decisions Need More than ‘Utilization’

• The network infrastructure exists to ensure applications (services) are delivered efficiently to meet the business’ needs

• Utilization and traffic flow statistics do not measure the end-user experience


measure the end-user experience

• High utilization is only a problem if response time degrades

• The best indication of how the application is performing for the end-user is to measure response times

Performance Considerations

Pre-Deployment

• Where can I get the most impact from deploying WAN Optimization?

Pilot Deployment

• How can I obtain before & after measurements for pilot testing?

A strategic approach to WAN optimization involves asking:


Post-Deployment

• What impact does optimization have on application performance and data volume across the WAN?

Ongoing Maintenance

• How can I troubleshoot problems after deploying WAN optimization?

The WAN Optimization Challenge

• WAN Optimization breaks the TCP session between client and server into 3 segments:• Segment 1: Between the client and the remote WAN Optimization device

• Segment 2: Between the 2 WAN optimization devices over the WAN

• Segment 3: Between the central WAN optimization device and the server

The WAN Optimization Challenge

2. Interception of application traffic obscures response times metrics necessary to quantify improvements

• Baseline transaction time and identify when performance degrades

• Monitor WAN latency to each site and alarm

• Optimization does not remove the need for management visibility• Baseline intelligently: e.g., data center consolidation,

application roll-outs, or normal planning for growth

• Optimize resource use: e.g., users still need to access local rather than remote replication servers
