Carriers may be handicapping cell phone networks
New research suggests that wireless operators may unwittingly be degrading performance on their networks as the technology they use to shuttle traffic around their networks gets more and more complex.
Researchers from the computer science department at University of Michigan along with experts from Microsoft Research discovered that "middleboxes"--or network hardware that performs tasks such as firewalling, deep packet inspection, and intrusion detection and prevention--may be slowing down network connections and even exposing wireless subscribers to security vulnerabilities.
According to the report published last month, "An Untold Story of Middleboxes in Cellular Networks," researchers observed … Read more
