Hi, that sounds good. What congestion control are you going to be specifying for your tunnel?

Specifically, MPLS can carry a number of different protocols as payloads. When the payload traffic is IP-based and congestion-controlled, the UDP tunnel SHOULD NOT employ its own congestion control mechanism, because congestion losses of tunneled traffic will already trigger an appropriate congestion response at the original senders of the tunneled traffic. When the payload traffic is not known to be IP-based, or is known to be IP-based but not congestion-controlled, the UDP tunnel SHOULD employ an appropriate congestion control mechanism. Furthermore, because UDP tunnels are usually bulk-transfer applications as far as the intermediate routers are concerned, the guidelines as defined in Section 3.1.1 of [RFC5405] SHOULD apply. > > Best regards, > Xiaohu > >> -----邮件原件----- >> 发件人: mpls [mailto:mpls-bounces@xxxxxxxx] 代表 Eggert, Lars >> 发送时间: 2014年1月8日 18:22 >> 收件人: IETF >> 抄送: mpls@xxxxxxxx >> 主题: Re: [mpls] Last Call: <draft-ietf-mpls-in-udp-04.txt> (Encapsulating MPLS >> in UDP) to Proposed Standard >> >> Hi, >> >> On 2014-1-2, at 16:14, The IESG <iesg-secretary@xxxxxxxx> wrote: >>> - 'Encapsulating MPLS in UDP' >>> <draft-ietf-mpls-in-udp-04.txt> as Proposed Standard >> >> >> this document needs to describe how it addresses the issues raised in BCP145 >> (RFC5405).
