Some observations: - the title is misleading; this is TRILL over UDP, not trill over IP. - the use of two different ports invites some potentially unintended problems, e.g., selective blocking of the control vs. data plane. IMO, given that TRILL's purpose is to extend Ethernet (not IP), this serv

Hi, all, I'm confused by the TCP encapsulation shown. If you place TRILL in TCP, you cannot ensure that the TRILL packets are aligned with the TCP headers. TCP is a bytestream, not message-oriented. I.e., you need to assume that TRILL packets could be split across TCP segments or multiple TRILL

PS - the idea that TCP segments within a single connection should ever have different DSCPs is a good example of why it's a bad idea to even 'think' of TRILL over TCP as direct encapsulation. I.e., that concept is inherently hazardous and should be avoided. Joe On 6/26/2017 10:1

Hi, all, This doc is very confusing. Its title and discussion throughout indicates “TRILL over IP”, including figs in Sec 4, but the only actual encapsulations described are TRILL over UDP and TRILL over TCP. IMO, this needs a very deep scrub to resolve. It would help to understand that the r
