[Nsi-wg] Intro to transit policies

Hi everyone Here is the document about transit policies and tree/chaining I promised to write-up on the last meeting. I have also included a section on exhange points. Is a bit rough, and I have at least one more section I would like to write up, but I have been to busy sitting in airplanes and with other deadlines. I hope this gives some insight into the policies of transit networks. Best regards, Henrik Henrik Thostrup Jensen <htj at nordu.net> Software Developer, NORDUnet
