2 About Version 12 With the proliferation of virtualization into the network infrastructure, Bring Your Own Device (BYOD), and cloud-based services, maintaining maximum network availability and performance is more difficult than ever before. Since problems can occur anywhere along a network path, from wired or wireless users through layer 2 switches, across the WAN, through the core and into the data center, engineers need full end-to-end visibility. But most performance management systems stop at the site s edge router. To fill gaps in visibility, network engineers need a combined portable and fixed solution to troubleshoot end-to-end and everything in between. NETSCOUT application-aware network performance management (AANPM) solution offers both fixed and portable components for always-on endto-end visibility. Simplicity of workflows ensures all members of IT team from front line support to network engineer will benefit from the solution. NETSCOUT AANPM solution extends deeper into your network to go where the problem is including end to end visibility for both the wired and wireless infrastructure. With OptiView XG version 12, NETSCOUT is announcing the integration of our flagship AANPM products OptiView XG and Visual TruView. These two products now work seamlessly together providing network engineers unique end-to-end visibility to quickly isolate and effectively solve network and application problems. The integration of XG s Path Analysis data into TruView and end-user response time metrics from TruView into XG provides complete analysis tools whether the engineer is in the NOC or at the end user location. Unlike some integrated products that simply switch user interfaces from one product to another, with OptiView and TruView, data is passed between the tools and presented in the same local user interface, resulting in a smooth workflow within the same tool, getting to root cause fast. For OptiView users who move frequently between different sites or client networks, as is the case with field technicians/engineers, version 12 provides a new Profile Management feature, enabling the user to save instrument settings and tests specific to a particular network environment. As networks continue to evolve and mature, higher speed links are being deployed more deeply into the network architecture. 10 Gigabit Ethernet once purely a data center technology is now working its way into the distribution and access layers as more equipment vendors offer 10G over copper twisted-pair cabling. XG users can now add the optional OptiView 10GBASE-T Adapter for full network analysis via a standard RJ-45 network port. OptiView XG version 12 also brings enhancements to the automated mapping features announced in version 11, with the ability to instantly map wireless networks. Additionally, XG users will always be assured of having the latest software code in their analyzer, with the automated check for updates feature. 2 of 5

3 End User Response Time (EURT) Metrics Through integration with Visual TruView, XG users now have full visibility into EURT metrics by user, site, server and application. A graphical heat map instantly pinpoints the application performance problem domain network or application with the ability to drill down into the real root cause. TruView is a unified application and network performance monitoring and troubleshooting appliance that watches over your global, regional, or even local groups of sites and users 24/7 by monitoring end-user experience enterprise-wide, timecorrelating packet, flow and management data to isolate the cause of performance problems. XG users can leverage their TruView appliance (with version 9 software) with XG Version 12, which integrates EURT data directly from TruView into the OptiView user interface. Unlike some integrated products that simply switch user interfaces from one product to another, with OptiView and TruView data is instantly passed between the tools and presented in the same local user interface, resulting in a smooth workflow within the same tool, getting to root cause fast giving network and operations teams more time to focus on critical projects. EURT is broken down into Application Response Time (ART), Data Transfer Time (DTT) and Network Roundtrip Time (NRT). A count of transactions by application and server allows the engineer to gauge the total impact on EURT. TCP health metrics (retransmissions, zero windows, out of orders and TCP resets) provide additional insight into the causes of poor application performance. Speed problem domain isolation with EURT metrics from TruView inside OptiView XG s user interface. When engineers are out troubleshooting in the network in the access layer, data center or remote sites having EURT data at their fingertips gives them unprecedented visibility across devices, paths, flows and applications, speeding the resolution of performance problems. TruView version 9 features the OptiView XG Graphical Path Analysis for end-to-end visibility of network infrastructure health. 3 of 5

4 Profile Management For engineers who move between sites or different clients, OptiView XG now enables saving instrument settings as site- or client-specific profiles, speeding instrument reconfiguration when moving between different networks. This makes XG an even more powerful and convenient tool for systems integrators, consultants, security/compliance auditors and other field teams. Wireless Network Mapping Save HOURS of manual labor! By enhancing the automated mapping feature released in Version 11, OptiView XG can now use data from wireless LAN controllers (WLCs) to create wireless network connectivity maps. The content of the map can be filtered by selecting one or more SSIDs, desired WLAN frequency bands, device and security types. Map details are user configurable, including link rates, channels used, AP mode and capacity, client count by AP, and more. Wired infrastructure connections show the entire network from endto-end so you are never without updated documentation of your network! Clicking the report icon instantly generates a Visio document of your displayed map. Profile management speeds instrument reconfiguration when moving OptiView between networks. 10GBASE-T Adapter As 10 Gig on copper becomes more prevalent, XG users can add this optional adapter to their analyzer for easy connectivity and testing of 10GBASE-T links. This adapter uses power from both the 1 Gig SFP and 10 Gig SFP+ slots on the XG tablet to drive full line-rate traffic capture and generation on a 10GBASE-T ( RJ-45 ) connection. Note: Some early OptiView XG units will require a minor modification by our service center in order to use the 10 Gig adapter. See ordering information for more information. AirMagnet SurveyPro v8.6 XG users with the optional AirMagnet SurveyPro software can now perform ac surveys. SurveyPro version 8.6 (for PRO and EXPT models of OptiView XG) is now fully compatible with the latest Wi-Fi technology, ac. With the use of an external USB.11ac radio, SurveyPro 8.6 and OptiView XG can be used to do comprehensive site surveys and simulations for.11ac networks. 4 of 5
