Every so often stores pop up about Skype being blocked in some country or the other, with some start-ups bragging how they did this. Now comes word that it is hard to detect Skype-packets. Russell Shaw points to analysis by Art Reisman, CTO of APconnections, a company that specialized in packet shaping technology. Reisman could not detect and block Skype traffic, which is contrary to claims of a Chinese service provider which used Verso’s technology. That claim has been upheld by an an independent agency. Aswath points out that numerous (successful) efforts have been made by others when it comes to identifying and blocking traffic. Last week there was also news of Skype texts being blocked in China, which I am guessing, is a different beast compared to detecting and blocking Skype voice communication packets.
