Outline Background IPv4 and IPv6 address allocation HEPiX IPv6 Working Group starts HEP IPv6 status update Working Group plans Summary 4 May 2011Kelsey, HEPiX IPv6 WG2

Background IPv6 talks at Cornell HEPiX (Nov 2010) –And earlier HEPiX talks... HEPiX Questionnaire on IPv6 (Sep 2010) –See my Cornell talk for details IPv6: National Networks are the most advanced Sites are not seeing any pressure (yet) –When will WLCG see IPv6-only sites? The problem areas –Applications (nobody looking at this) –Monitoring, System and Network tools, Security, etc. 4 May 2011Kelsey, HEPiX IPv6 WG3

IPv4 Addresses (Nov 2010) From Geoff Huston ( ) Projected IANA Unallocated Address Pool (global) Exhaustion: 09-Jun-2011 –Only 12/256 (/8) addresses are unallocated –< 5% Projected RIR Unallocated Address Pool (regional) Exhaustion: 22-Jan May 2011Kelsey, HEPiX IPv6 WG4

IPv4 Addresses (now) IANA allocated the last five /8 address blocks on 3 Feb 2011 APNIC became the first RIR to run out of freely allocated IPv4 addresses –On 15 Apr 2011 RIPE NCC expected to be next RIR –Late 2011 or early May 2011Kelsey, HEPiX IPv6 WG5

IPv4 Free /8 blocks 4 May 2011Kelsey, HEPiX IPv6 WG6

IPv4 address assignment rate 4 May 2011Kelsey, HEPiX IPv6 WG7

IPv6 allocation rate 4 May 2011Kelsey, HEPiX IPv6 WG8

HEPiX IPv6 WG Agreement at end of last year Work has now started –Members being identified – list configured –1 st meeting held last week Main agenda point was to discuss the mandate and plans 4 May 2011Kelsey, HEPiX IPv6 WG9

HEP IPv6 status update DESY –see Site report on Monday –Deploying IPv6 test networks –Soon allow applications testing CERN –planning now for network implementation –Testbed available in the summer No reports of work on HEP applications 4 May 2011Kelsey, HEPiX IPv6 WG10

IPv6 WG plans Do not duplicate other activities Very useful to share experiences and work together Need to expand membership of the WG –Today mainly network and WLCG Tier2 experts –Need to expand coverage and find other experts Applications Security Middleware Monitoring 4 May 2011Kelsey, HEPiX IPv6 WG11

IPv6 WG plans (2) During 2011 –Deploy a distributed testbed To allow tests of connectivity, applications, monitoring tools, etc. –Share experiences and collaborate –Survey of HEP applications IPv6 readiness –Survey of Monitoring and Management tools –Study of Security issues –Initial recommendations by end 2011 When/how do we migrate? 4 May 2011Kelsey, HEPiX IPv6 WG12

IPv6 WG plans (3) 2012 –To be used for more testing –Making applications V6 ready –Planning and advice for migration and end system and firewall configuration LHC shutdown in 2013 is likely to be earliest date for wide deployment in WLCG 4 May 2011Kelsey, HEPiX IPv6 WG13

IPv6 WG plans (4) Need to plan for coping with IPv6-only sites (WN, Virtual machines,....) should they appear –We do not know how soon this could happen Working group logistics –Mail list already exists –Wiki – at CERN –Indico – agenda pages (under HEPiX) Weekly phone/video meeting Sharing information and experiences F2F meeting in June at CERN (after the World IPv6 day on 8 th June) 4 May 2011Kelsey, HEPiX IPv6 WG14

Summary HEPiX IPv6 working group has now started Looking for widening expertise and participation Volunteers welcome! 4 May 2011Kelsey, HEPiX IPv6 WG15
