AT&T’s Anti-Infringement Patent

Network surveillance is a persistent issue that privacy advocates warn about on a regular basis.

Analysis: ipoque, DPI, and Network Neutrality

German Deep Packet Inspection (DPI) manufacturer ipoque has produced a white paper titled “Deep Packet Inspection: Technology, Applications & Network Neutrality.” In it, the company distinguishes between DPI as a technology and as technology possessing potential social effects.

Two  modes of management … Continue reading Analysis: ipoque, DPI, and bandwidth management
