| Analysis of some of our routes shows the potential for asymmetric | routing...that is...the transmit path will be different than the return path | for packets.
Asymmetry has been a reality for quite some time now; in fact it was happening during the NSFNET backbone service days, since the information in the PRDB was often in a shambles. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Not surprisingly, the PRDB was as good as the information which was submitted by customers of the NSFNET BNS, though
Sean: This is misleading at best... there was a lot of checking done to try to proactively catch mistakes. As someone who was working with/supporting the NSFNET configuration process, I do not know of other customers claiming that "the PRDB was often in a shambles" via phone, email, or third-party reports.
Sean.
