Re: Security over SONET/SDH

Link encryption isn't to protect the contents of the user's communication. There is no reason for users to trust their ISP more than a national institution full of people vetted to the highest level. What link encryption gets the user is protection from traffic analysis from parties other than the ISP. You've seen in the NSA documents how highly they regard this traffic analysis. I'd fully expect the NSA to collect it by other means. -glen -- Glen Turner <http://www.gdt.id.au/~gdt/>
