Hi all, I just submitted a revision (https://www.ietf.org/rfcdiff?url2=draft-xu-intarea-ip-in-udp-05). Any further comments and suggestions are welcome.
BTW, it said in Google's Espresso paper (http://www.google.com.hk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&cad=rja&uact=8&ved=0ahUKEwib0cntgfnWAhVHso8KHWF2BmQQFghAMAM&url=http%3A%2F%2Fwww.cs.princeton.edu%2Fcourses%2Farchive%2Ffall17%2Fcos561%2Fpapers%2Fespresso17.pdf&usg=AOvVaw2SgiqQ-ahnvRnEN_QYlxrZ) that "...We use a range of addresses for the encap IP header for sufficient hashing entropy as switches in the aggregation layer cannot look beyond the outer IP header for hashing..." Note that IP-in-GRE and MPLS-in-GRE encapsulations are currently used for incoming and outgoing traffic in Google's Espresso respectively according to the above paper. I believe that IP-in-UDP (https://tools.ietf.org/html/draft-xu-intarea-ip-in-udp-05) and MPLS-in-UDP [RFC7510] should be better choices than IP-in-GRE and MPLS-in-GRE respectively once the former could be supported by major chip and network vendors. Fortunately, MPLS-in-UDP has already been supported by major chip and network vendors since its corresponding IETF standard was published. I believe the same thing would happen on IP-in-UDP :) Best regards, Xiaohu > -----邮件原件----- > 发件人: [email protected] [mailto:[email protected]] > 发送时间: 2017年10月18日 9:06 > 收件人: Hamid Assarpour; Yiu Lee; Xuxiaohu; Fan Yongbing; Yiu Lee; Yongbing > Fan; Shaowen Ma > 主题: New Version Notification for draft-xu-intarea-ip-in-udp-05.txt > > > A new version of I-D, draft-xu-intarea-ip-in-udp-05.txt has been successfully > submitted by Xiaohu Xu and posted to the IETF repository. > > Name: draft-xu-intarea-ip-in-udp > Revision: 05 > Title: Encapsulating IP in UDP > Document date: 2017-10-17 > Group: Individual Submission > Pages: 11 > URL: > https://www.ietf.org/internet-drafts/draft-xu-intarea-ip-in-udp-05.txt > Status: https://datatracker.ietf.org/doc/draft-xu-intarea-ip-in-udp/ > Htmlized: https://tools.ietf.org/html/draft-xu-intarea-ip-in-udp-05 > Htmlized: > https://datatracker.ietf.org/doc/html/draft-xu-intarea-ip-in-udp-05 > Diff: > https://www.ietf.org/rfcdiff?url2=draft-xu-intarea-ip-in-udp-05 > > Abstract: > Existing IP-in-IP encapsulation technologies are not adequate for > efficient load balancing of IP-in-IP traffic across IP networks. > This document specifies additional IP-in-IP encapsulation technology, > referred to as IP-in-UDP (User Datagram Protocol), which can > facilitate the load balancing of IP-in-IP traffic across IP networks. > > > > > > Please note that it may take a couple of minutes from the time of submission > until the htmlized version and diff are available at tools.ietf.org. > > The IETF Secretariat _______________________________________________ Int-area mailing list [email protected] https://www.ietf.org/mailman/listinfo/int-area
