Adlex Launches UserVisibility Web: DoubleClick To Implement New Performance Management Appliance

Adlex, Inc. announced today the general availability of UserVisibility Web, a new appliance for use by enterprise Web sites for monitoring the actual response time all users experience when interacting with the Web site. It joins the existing family of Adlex UserVisibility performance management appliances. Adlex is a provider of "all-in-one" performance management appliances that monitor all traffic to determine the actual response times experienced by individual users of applications using Internet, WAN or VPN networks.
    Adlex also announced DoubleClick, Inc. (Nasdaq: DCLK), the leading digital marketing solutions company will implement UserVisibility Web after a successful beta program, and will use it to help manage and monitor the performance of its DART (Dynamic Advertising Reporting Targeting) system. DART is a Web-based service that enables sites and networks to manage their ad management, serving and reporting functions through DoubleClick`s central servers. With a distributed system architecture and ad servers located throughout the world, DART offers the scalability, reliability and power needed to deliver any volume of ads.
    UserVisibilityWeb measures the actual response time experienced by every remote user by simply observing the network data going to and leaving a customer`s data center. It provides response time measurement and diagnostics based upon key metrics for transaction or page load time, round trip time, retransmissions and actual user throughput.
    DoubleClick will implement UserVisibility Web to monitor and manage its DART system to ensure that DoubleClick`s customers are providing the best response time to each and every visitor responding to an online ad served by DART.
    "We need to get data in real-time that measures the real experience of an end user. Then we need to understand it so we can make changes to keep our service at proper levels," said Mehdi Daoudi, Vice President of Quality of Services and Operations at DoubleClick. "By deploying Adlex`s UserVisibility Web we can further solidify our position as the leading provider of global digital marketing solutions."
    What makes UserVisibility Web different is that it monitors all traffic at a "user session level" (differentiating it from RMON2-based probe approaches), providing actual performance of "individual or aggregated users" at the instant they are accessing "every page or transaction." Implementation is via a passive probe that does not generate its own traffic for measurement, and does not require actual traffic to pass through it, and thus, is also not a point of failure. The Adlex probe is only installed at the data center where the application servers reside. It is device-independent (it collects its own data -- not from any other devices like servers or routers) and non-intrusive (it does not require any software agents on the client side or software integration on the application code or server side). Adlex monitors both Web http and SSL traffic.
    "Companies like DoubleClick need to know the response time they are delivering to their customers," said Tad Witkowicz, President and Chief Executive Officer of Adlex. "Until now, companies monitoring performance of their users relied on simulations and estimates to gain insight into the user response time issue. We enable them to determine response time with 100% accuracy."

    About Adlex UserVisibility Appliances

    The Adlex family of UserVisibility appliances provides "user" and application aware response time management. UserVisibility technology measures the actual response time experienced by every remote user by simply observing the network data going to and leaving a customer`s data center. It provides response time measurement and diagnostics down to an individual user by application type, by application server and by time of day.
    The individual products within the UserVisibility family address specific IP-based applications.

    --UserVisibility Web: for use by enterprise Web sites for monitoring the actual response time all users experience when interacting with the Web site

    --UserVisibility VPN (Virtual Private Network): for enterprise IT customers who are deploying VPNs and require end user response time visibility and performance diagnostic capabilities. It also provides the basis for service provider SLAs by measuring end-to-end Internet/WAN latency, re-transmissions and actual user throughput.

    --UserVisibility WAN: for enterprise IT customers, ASPs and MSPs who require the monitoring and diagnostics of the response time experienced on a user by user session level basis when accessing applications over a private enterprise IP network. UserVisibility WAN baselines and maintains an individual user`s profile of performance, alerts to abnormalities and captures session level details for real-time or post-facto troubleshooting, trending analysis or capacity planning.
