  1. HEPiX IPv6 F2F Meeting QI Fazhi [qfz@ihep.ac.cn] Computing Center, IHEP July  4, 2013. CERN IPv6 Network Status in IHEP/China

  2. Outline CSTNet CERNet CNGI IHEPNet IPv6@IHEP SDN@IHEP Summary *

  3. CSTNet China Science and Technology Network Domain name: *.ac.cn An academic network system operated by Chinese Academy of Sciences Covers the whole country via 13 regional sub-centers to form the domestic backbone Operation Center: CNNIC

  4. CERNet China Education & Research Network Domain name is *.edu.cn the largest academic networkin China Connects more than 200 cities Provides connectivity to ~2000 colleges and institutes.

  5. CNGI China Next Generation Internet A government-supported IPv6 project A largest ipv6 pure network in the world the largest academic networkin China consists of six core networks implemented by China Telecom, China Netcom/CAS, China Mobile, China Unicom, CERNET and China Railcom

  6. CERNet2 The CERNet part of CNGI 2.5~10Gbps backbone

  7. CSTNet2

  8. IPv6 History @IHEP • 2008 • 1Gbps IPv6 Link to CNGI, Part of IHEP endpoints support IPv6 • 2009 • IHEP started to use the IPv6 Link to do the HEP data transfer between the cooperation Universities(SDU/…) • 2011 • IHEP DNS supports IPv6 • 2012 • Dual Stack IHEP Campus Network, 10Gbps IPv6 link CNGI(Fund from The National Reform and Development Committee ) • 2013 • IHEP Gird-Area Network supports IPv6(test bed) • The SDN @IHEP project start up(IPv6 enabled)

  9. IPv6 deployment principles @IHEP • Dual Stack • The same management and security policies with IPv4 • Users (IP) management • Monitoring • Access control • Step by Step • Public Network Services • DNS • WEB • Email • …… • Grid & Cloud Computing

  10. DHCPv6 @IHEP （Dibbler） • Feature • OS supported • Linux 2.4/2.6; Windows NT4.0,XP,WIN7/8; Mac OS • Multi-server supported • Autoconguration procotol supported • Stateful /Stateless • IA,TA,PD client IP configuration control • Dhcpv6 relay request supported • Per client conguration by MAC or UUID • Server caching • Dibbler • Open source software • Author :Tomasz Mrugalski and Marek Senderski from Gdansk University of Technology • A dhcpv6 solution include • Server • Client (Support Windows XP) • Relay

  11. Current Status • Infrastructure deployment ✔ • All the network devices(switch/router/firewall) support IPv6 • Infrastructure Monitoring ✔ • Easy to do (all the devices are dual stack supported) • Cacti & Nagios with IPv6 patch • User(IP) management ✔ • The ipdb & access control system ✔ • DHCPv6 server: ✔ • DHCPv6 server service (DHCPv6 serverDibbler server; running on the same server with DHCPv4) • All the office users use the dibbler client to achieve ipv6 address. • Security ✔ • Firewall: ✔ • Network traffic and user behavior analysis: ✔

  12. Current StatusUser Management & Access Control • Central Database – IPDB • MAC Address is the key • Static IP address for Users • IPv6/IPv4 host addresses assigned by Dibbler/DHCPv4 servers, based on the MAC address declared in the IPDB • Central Control System • User information management • Network devices information management • Dhcpd configuration auto-updated • Release access policies to the proper user switch

  13. Current StatusUser Access Control Procedure MAC/User Name/Email/Tel/Building/Room number/Plugin number/…… Online Register Submit no Approved by Admin ok Assign IP address save Dibbler/DHCP configuration updated Switch configuration updated IPDB Switch information: IP/Port/Vlan/ Switch-Room/Plugin Number relationship Vlan/IP subnet/switch-port relationship IP/MAC relationship ……

  14. Current StatusGrid Area Network • Grid Computing Environment • The gridftp(ipv6) test bed was set up • IP Name: ui01-hepix.ihep.ac.cn • ui01-hepix-v6.ihep.ac.cn (2401:de00::9998)   • ui01-hepix-v4.ihep.ac.cn (202.122.32.172) • OS: Scientific Linux 5.9 x86_64 • CPU: Intel E5345 X 2 • Mem: 16GB • DISK: 320GB. Will add to 6TB(2TBX3 Raid 0). For Transfer test. • Middle ware: Gridftp server and EMI-2 UI • Web server: nginx with ipv6 support

  15. IPV6 check result New CA server included in EGI-ca-policy 1.53 Gridftp server or client ca version less than 1.53 will failed to transfer

  16. Problems • No enough resources and applications in the IPv6 internet world • Most of the IHEP IPv6 traffic are video/iptv/…… • Less scientific data go through IPv6 • And Then…….SDN@IHEP Project

  17. What is SDN?

  18. SDN@IHEP • Goal • A flexible, reliable and high performance HEP data transfer network (virtual and private) and system platform in China • IPv4 and IPv6 supported • The traffic can be switched between IPv4 and IPv6 infrastructure and physical path automatically or manually • SDN@IHEPIHEPDTN • End user network • Backbone network（IPv6 & IPv4） • SDN Switch (L2VPN gateway & Openflow supported) • Control center (API to Application) • Applications(FTS/NMS/…….) • Members • IHEP/SJU/SDU/TsingHua/…… • Network manufacturer：Ruijie Networks, A high performance network union lab （IHEP-Ruijie) 高能所－锐捷网络高性能计算网络联合实验室

  19. SDN@IHEP model

  20. Final Result

  21. Summary • IPv6 infrastructure @IHEP is running well • The IPv6 management and support platform is running well • The Gridftp testbed @IHEP for IPv6 is ready • We would like to jion the mesh test for data transfer • IHEP SDN project will build a platform in China for HEP(BESIII/Daya Bay Experiments) data transfer with the current/IPv6 network infrastructure

  22. Thank you
