The organisation did not want to build a separate, local IT infrastructure for its employees in the branch office, so it provided access to data, email and applications housed in the
This was not just a matter of inconvenience, recalls Steven Ward, the BSC’s IT manager. “There was a huge amount of frustration among the remote users,” he says.
“Not only was productivity gone, but also morale. If you’re stuck in the office out in the sticks with a system that doesn’t really work, you start to feel a bit neglected.”
When Ward decided to resolve the issue, the first option he considered was to rent a two megabit leased-line between head office and
So, in order to optimise the performance of the existing network, he investigated WAN acceleration technology. That led him to Citrix’s WANScaler product, technology acquired by the company with its August 2006 acquisition of Orbital Data.

This had a dramatic impact on system performance, as the BSC’s own testing revealed. For example, Ward says that a 2MB .pdf would have previously taken about 38 seconds for someone in the branch office to attach to an email. Now, it takes just 4.4 seconds the first time it is attached, and about two seconds for every subsequent attachment of that document.
The cost of the WANScaler implementation was far preferable, says Wade. “The initial hardware outlay was £10,000, just over the annual support cost for the leased-line. But we only pay £700 a year in maintenance.” Wade adds that he considered competitive products from vendors such as Riverbed and Juniper, “but it seemed to me that they provided the same functionality at a greater cost.”
Not only has the system restored productivity, but also delivered a much needed morale boost. “As soon as you see some cutting-edge technology being used to solve your problem, you start to feel a lot better,” says Ward.
