DPI Goes Mobile

9:10 AM -- More mobile operators are turning to deep packet inspection (DPI) to manage data traffic on their networks, according to Continuous Computing Corp.

The vendor claims that about 10 Tier 1 mobile operators use its DPI software. (See Continuous Pushes LTE, DPI.)

Since a small number of heavy data users can hog a lot of bandwidth and slow down mobile broadband networks, operators increasingly look to technologies like DPI to combat this scenario. With DPI, operators can monitor traffic patterns and prioritize time-sensitive applications like voice and streaming media.

Unstrung has reported that Telefónica O2 Germany GmbH & Co. OHG started using DPI in July this year. The operator said it wanted to monitor customers' service usage patterns and have the ability to throttle bandwidth when necessary. O2 found that 5 percent of its customers use 80 percent of its 3G network capacity. (See O2 Germany Turns On DPI and MWC Preview: Rise of the Traffic Cops.)
