Summary

The greedy nature of many Internet-based applications and the over-subscription model of the Internet poses challenges to network operators and regulators as they strive to maintain Internet freedoms that subscribers have come to expect. At the heart of the contentious issues of Internet bandwidth traffic management and net neutrality is the technology of deep packet inspection (DPI).

"DPI will become more important to ISPs to manage online broadcasting and digital rights," states Lawrence Surtees, study co-author and vice president of communications research at IDC Canada Ltd. "At the same time, ISPs must use this technology judiciously and recognize that their role should not be to serve as content police."
