'Fundamental change' causing greater bandwidth expenditure
ElKhayat: 80% of enterprise data traffic now goes over the WAN

According to Riverbed's Taj ElKhayat, Middle East enterprises are spending more on bandwidth than three years ago due to what he called a fundamental change in traffic patterns.

The vendor's managing director for the region explained that, traditionally, 80% of enterprise traffic has been on the LAN (local area network), with 20% on the WAN (wide area network). However, ElKhayat said that this ratio has now inverted, with 80% of enterprise data traffic going over the WAN, therefore pushing broadband requirements up.

"The main trend driving this has been the centralization of applications and services either in the data centre or in the cloud," he told ITP.net.

ElKhayat added that there were a number of other reasons behind enterprises' increasing expenditures on bandwidth. He said that more devices are now connecting to enterprise networks, both for personal and business use, and that the amount of video content being transmitted across corporate networks is also on the rise.

"All of this has contributed to a greater need for bandwidth which has, in turn, called for larger bandwidth-related investments," he said.

ElKhayat said that, though the cost of bandwidth has been decreasing in the Middle East, enterprises are still spending more because their needs have skyrocketed. This means that they are beginning to turn to bandwidth management solutions in order to make the best use of the bandwidth they have, he said.

"Though bandwidth costs in the region may now be less than before, data volumes are only set to rise, leaving organisations pressed to find a more permanent solution to their bandwidth needs," he said.

"Many are therefore looking for bandwidth management solutions to cope with the increased volumes of data."

ElKhayat said that a strong case could be made for deploying a WAN optimisation solution, citing research on ROI from IDC. Indeed, he said that this would be often be preferable to simply shelling out for more bandwidth.

"Further benefits of IT cost reduction, IT staff efficiency, user productivity enhancement and downtime reduction, and an improvement in business productivity are all reasons why organisations are choosing to deploy bandwidth management solutions instead of merely purchasing more bandwidth," he said.
