I agree with Pekka and itojun. Please also recall that there exist toaster-class devices whose only persistant storage is flash RAM or some similar technology that has a finite number of write cycles before becoming, well, toast. In such environments preserving frequently-changing data across reboots is not a trivial matter, and I'm not convinced that flow labels pass the cost/benefit test. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
