Visual Networks, a maker of WAN performance management software, Monday announced it has enhanced its product, separated it from a hardware platform and broken it up into pieces that the customer can mix and match.

In a bid to give enterprises and service providers more flexibility, Visual separated its software from its Analysis Service Element/Digital Service Unit (ASE/DSU) hardware and divided it into modules for different capabilities, an offering it calls Visual UpTime Select. Cisco, which integrates Visual's software in its Internetwork Operating System for several of router models, also will now offer it in module form.

Visual's new way of offering its products will help M&T Bank fix network problems in its 712 locations spread across several U.S. states, according to Jim Finn, vice president of telecommunications at M&T, a regional bank based in Buffalo, New York. The bank has full-fledged Visual ASE/DSUs at 50 of its main locations, but buying one for each branch wouldn't be economical because the performance management software is rarely needed at any given small branch, Finn said. The bank plans to buy bare-bones DSUs from Visual along with "token" licenses, which are basically prepaid licenses to use the performance management software for a given time, he said.

The Visual ASE/DSU, which essentially serves as a high-speed modem for a wide-area Frame Relay or ATM connection, is distinguished from conventional DSUs because it can collect a variety of data about the performance of the wide-area connection and the applications running over it. With Visual's add-on software, IS managers can use that information to do real-time troubleshooting, track recurring problems, find the sources of problems and determine whether critical applications are getting the kinds of service they should be, according to Robert Norberg, director of product management at Visual Networks, in Rockville, Md.

Now customers can buy the DSU by itself, at prices starting at $1,195, and buy only the management software modules they need. In addition, a new architecture makes it easier to integrate the management software with system management applications such as HP. OpenView and Aprisma Management Technologies' Spectrum, Norberg said.
