Cisco Application Visiblity and Control – What’s in it for me?

Cisco’s NBAR2 delivers detailed visibility into application performance and prioritization

A long long time ago in a galaxy far away…
I read a research note from Gartner (circa 2001) that suggested deep packet inspection (DPI) would render other forms of measuring application performance less meaningful.

Has that day come?

Maybe, maybe not, but this gets us a lot closer and the data could prove invaluable providing metrics, diagnostic, and deep-dive data to application performance processes within an enterprise or service provider network.

With the flurry of news over the last week about vendors (ManageEngine, CA, Plixer) leveraging this new application performance data I had to take a closer look. What I found was incredibly interesting.

AVC stands for application visibility and control. It is Cisco’s built in capability for discovering and controlling applications on the network. Leveraging NBAR2, Cisco’s next generation of DPI, more than 1000 applications are recognized out of the box, and this data is available just like standard netflow data for visualization in Cisco’s tools or 3rd party tools.

The demand for bandwidth consumption in the enterprise is growing along with video, mobile and cloud. While this is often good for business it can be challenging for operations who need visibility into which applications are running on the network, performance metrics by application, and a way to manage and prioritize to control the end-user experience.

How many times have you walked around your office and seen too many desktops watching something on youtube? Listening to music streaming from youtube is not the most productive use of bandwidth I think.

NBAR2 provides visibility at the application level for collection of performance metrics such as:
– breakdown of applications in detail going accross the network
– by IP, by port, by application
– in-bytes
– in-packets
– in interface
– out interface
– out bytes
– out packets
– response time
– application delay
– network delay
– client delay
– server delay

Because AVC is built into the latest gear (ASR 1000 and ISR G2 routers) it may eliminate the need for other costly DPI hardware currently used to measure application performance or shape traffic.

Check out this very short video demo of ActionPacked Networks net flow reporting tool showing the new application performance data.

This data is awesome and needs to be accessible to APM tools to diagnose performance issues as well as fed into analytics (ITOA) engines that perform anomaly detection and correlation.

AVC also supports prioritization of applications using QoS to improve user experience for critical applications and enforce fair-use policies.

CA Network Flow Analysis Leverages Cisco’s Next-Generation Technology to Deliver Deep Insight into Application Performance

Self-Learning Analytics Enable IT to Spot Anomalies, Improve Service Levels and Reduce Costs

NEW YORK, N.Y., January 27, 2014 – CA Technologies (NASDAQ:CA) today announced a new version of CA Network Flow Analysis that leverages Cisco’s next-generation technology to provide IT organizations with application-centric insights to better spot anomalies, improve service levels and reduce operational costs.

CA Network Flow Analysis automatically recognizes more than 1,000 applications—quickly giving network managers deep visibility into application traffic patterns and behavior. The solution also makes it easy for network managers to create profiles for their organization’s custom applications.

This insight empowers IT to pinpoint active or potential issues with service delivery, plan and validate resource needs for new applications, optimize utilization of network resources, and avoid unnecessary infrastructure costs.

CA Network Flow Analysis complements these capabilities with patented anomaly detection that learns about the network over time and automatically detects and creates alarms for a wide range of anomalies that can impact performance and create security risks. This empowers IT to proactively safeguard critical service levels while reducing the cost and headaches associated with network troubleshooting.

“Enterprise IT organizations that don’t aggressively evolve their ability to manage their networks from an application-centric perspective will inevitably wind up throwing too many staff-hours at service-level assurance and getting too little in return,” said John Smith, general manager, infrastructure management, CA Technologies. “With CA Network Flow Analysis, customers achieve far superior results with less work—significantly enhancing IT’s overall ability to deliver more value to the business.”

T-Systems, a global IT services and consulting company headquartered in Germany, uses CA Network Flow Analysis to provide application-centric monitoring as a cloud service for its customers. T-Systems ICT-Monitor extracts data without additional hardware in the customer environment and provides application response time for applications like SharePoint and others.

“Application-centric network monitoring has historically required us to associate applications with known ports, but that approach is becoming untenable as more applications use HTTP and dynamic ports,” said Christian Remer LeiterProduct Management APM at T-Systems. “By giving us the insight we need without depending on known ports, CA Network Flow Analysis is enabling us to stop finger-pointing and quickly resolve network-related performance issues as they arise.”

CA Network Flow Analysis leverages Cisco AVC (Application Visibility and Control) and NBAR2 (Next Generation Network-Based Application Recognition) technologies to simplify and integrate the detection and analysis of application-specific traffic. It also harvests data directly from network devices—making it more cost-effective to deploy, maintain and upgrade.

CA Network Flow Analysis has received Cisco’s Interoperability Verification Test (IVT) certification, validating its support for AVC.

“Network performance management no longer means simply reporting top talkers and top traffic loads by port and protocol,” said Jim Frey, vice president of research, Enterprise Management Associates. “Network managers must now be able to relate ports and protocols to specific applications, understand response times for those applications, and apply analytics to reveal potential issues on a proactive basis. The latest release of CA’s Network Flow Analysis makes progress on all of these fronts.”

CA Network Flow Analysis embraces CA Technologies application-driven network performance management model for managing IT infrastructure, applications and services.

CA Technologies is demonstrating CA Network Flow Analysis this week at Cisco Live 2014 Milan.
