An inconvenient fact (for opponents of network management):
A survey by the Japan Internet Providers Association shows 40% of Japanese ISPs perform network management, according to Yomiuri Shimbun, and the trend is growing.
Of the 276 respondents, 69 companies said they restricted information flow through their lines. A total of 106 companies, including those that rent lines from infrastructure owners, impose such restrictions. Twenty-nine companies said they were planning to take similar measures.
This is somewhat ironic because advocates for a centrally-planned national broadband strategy led by bureaucrats cite Japan as one of the successful examples the U.S. should follow. See, e.g., “Down to the Wire,” by Thomas Bleha in Foreign Affairs (May/June 2005).
