  1. IPv6 Testing Within Native IPv6 GEANT cfriacas@fccn.pt GEANT-TF, Amsterdam, 06/06/2003

  2. Topics • Small Tests (already done) • RTTs • Services • Traffic Generation

  3. Small Tests (already done) • FTP • Fccn (PT) – Cesga (ES) • using ftp://ftpu:ipv6/ftp.ipv6.cesga.es • Upload and Download • Mput/Mget (anybody still using command line?) • 100Mb Random Generated File • dd bs=1 count=size if=/dev/urandom of=./testfile

  4. Small Tests (already done) • Traceroute (work2do: dns!) • Transfer Rates traceroute6 to ftp.ipv6.cesga.es (2001:720:1210:e:2b0:d0ff:fef3:5ec8) from2001:798:2015:10aa::6, 30 hops max, 12 byte packets 1 2001:798:2015:10aa::5 (2001:798:2015:10aa::5) 10.935 ms 10.955 ms 10.824 ms 2 2001:798:2015:10aa::2 (2001:798:2015:10aa::2) 11.052 ms 11.123 ms 11.027 ms 3 2001:720::240:2 (2001:720::240:2) 11.1 ms 11.116 ms 11.099 ms 4 2001:720::240:22 (2001:720::240:22) 138.58 ms 80.632 ms 87.451 ms 5 2001:720:1200::1:2 (2001:720:1200::1:2) 20.015 ms 19.978 ms 19.935 ms 6 2001:720:1210:e:2b0:d0ff:fef3:5ec8 (2001:720:1210:e:2b0:d0ff:fef3:5ec8) 19.869 ms 19.872 ms 19.821 ms 104857600 bytes sent in 147.15 seconds (695.88 KB/s) 104857600 bytes received in 138.58 seconds (738.94 KB/s)

  5. RTTs • Setup of one Loopback Address to serve as a test «beacon» for other NRENs • FCCN: 2001:690::1 • DNS integrated • Objective: • To measure Roundtrip Times between all native members • easily • anytime

  6. Services«Testing Methodology» • Distributed testing isn´t easy to coordinate • Need to decide who wants to participate • Need to decide if participation is total or parcial (some people may not want to take part in all tests) • Gather as much data as possible today • Discuss each test, trying to improve them • Philosophy is: each participant does both the server and the client side

  7. Services • DNS • FTP • WEB • NTP • EMAIL • VIDEOCONFERENCING • ... ??? (suggestions please)

  8. DNS • Everybody: • Setups a Zone on a DNS Server • With Zone Transfer Permission • Transfers other NRENs Zones, using: DIG @server «zone» axfr • Needed Data: • DNS Server Address/Name • Zone to transfer

  9. FTP • Rediris: ftp.ipv6.cesga.es (ftpu/ipv6) • Fccn: ftp6.ip6.fccn.pt (anonymous) • More??? Each new NREN needs to: • «broadcast» authentication data for its own server • «broadcast» which directory has write=on • generate own 100Mb Testfile • Checksum mechanism? • The idea is: • get all the testfiles from each testfile source • uploads his own testfile everywhere

  10. WEB • Everybody: • Setup of an AAAA record (www) on a zone • Insertion of a Keyword on the index page • Broadcast of the address • Access all participants’ servers and retrieve all keywords • Alternative: • no keywords, people just give out an existent http:// URL on their network

  11. NTP • Everybody: • Setups their server • Synchronizes it to some dante’s server? (lower stratum) • Broadcasts the address • Uses a client to run ntpdate and ntptrace (ipv6 versions)

  12. EMAIL • Everybody: • setups MX record on a zone pointing to a name with only a AAAA record • setups a mailbox called «geant-test» on that server • broadcasts its own domain • sends a message to everyone’s address, containing text and an attached image. • Suggestions: sendmail/postfix

  13. VIDEOCONFERENCING • «Maximum Setup»: 2-person call • Linux: Gnomemeeting • http://www.gnomemeeting.org • http://www.join.uni-muenster.de • Windows: Netmeeting • http://www.microsoft.com • On IPv6 (still unavailable!): • MCU • Directory Services / Gatekeeper

  14. Traffic Generation • MGEN6 (over Unix/Linux) • http://matrix.it.uc3m.es/~long/software/mgen6 • Easy and Quick Way to Generate Traffic • «Boost your traffic graphs»  • Generator/Analyzer Hardware • FCCN has a STM-1 capable SPIRENT box • GARR has something similar? (mentioned in 3rd meeting) • Anybody else...?

  15. The End… • E-Mail • ip6adm@fccn.pt • helpdesk@fccn.pt • Links • http://www.ip6.fccn.pt (dual-stack) • http://www.dante.net/nep/ipv6
