 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

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

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

Services

 DNS

 FTP

 WEB

 NTP

 EMAIL

 VIDEOCONFERENCING

 ... ??? (suggestions please)

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

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

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

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)

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

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

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...?
