News:
BNL and FNAL primary links now 2x8.5Gbps
RAL 10G backup link will be ready in 2/3 months.
PIC backup link now on a different path inside the Geant network.
RAL update
New Computer centre building. Some issue, now sorted out.
The second 10G link for LHCOPN will be delivered in 2/3 months.
Currently design the next generation network architecture.
JANET update
Current network: SuperJANET5 until 2013.
Services: JANET IP (40G core), JANET Lightpath (Ethernet over MPLS), JANET Aurora (dark fibre research platform)
Positive 100G trials with Nortel and Ciena
Monitoring
RAL: using the Netsight of Janet, Cacti at the site (weathermap), Scrutinizer (commercial, sflow netflow)
KIT: ping, nagios, Netview (sends email and sms), Cacti (BGP monitoring), Netflow (Cisco product), Syslog
NL-T1: Nagios, Cacti, PHP-Syslog-NG, Rancid, Remedy. BGP monitored by Nagios. Availability: ping from nagios.
CNAF: MRTG(traffic) NAgios (status availability and alarms), Netflow analyzer Pro,
CERN: spectrum (commercial, link status and stats), Nagios (BGP
NDGF: Nagios, ZINO (home maded, link status, BGP), sierra (home made sflow collector) Alcatel and Ciena NMS.
IN2P3: Cricket for statistics, smokeping (remote hosts), Netsurv (home made)
PIC: Cacti, Nagios (BGP, interfaces)
FNAL: Nagios, Cisco IP SLA, RoutePlotter (traceroute and RTT changes monitoring) Netflow analysys.
ESnet: Spectrum (devices, links, LSPs. Main tools for the NOC). E2EMON (but not used becaouse slower in reporting)
USLHCnet: Monalisa (weathermap, link status and availability, topology chnages, send alarms), Perfsonar-PS (feeds E2emon)
Monitoring WG
Who is using perfsonar MDM:
CNAF is using the MDM to check the network is able to run 1G data transfer between T1-T1.
KIT: No, only checking it displays correct information
NL-T1: No
CNAF: yes: data transfers, hades, weathermap, OWD, traceroute
CERN: no
NDGF: no
In2P3: no
PIC: no, especially because the backup link cannot be added. Would like to have jumbo support.
FNAL:no
Comments:
Should be only a measurement system, not alarming/monitoring
Who are the users? Application managers, network engineers.
Operations
Twiki not updated
Integrate or tickets in the the standard GGUS system? Pro and cons.
No email interface to ggus will be implemented.
Support may be reduce after the end of EGEE.
We need a SLD and monitoring.
ENOC after EGEE
EGEE ends April 2010, EGI should follow. Only 0.5 FTE for networking is foreseen.
LHCOPN operations support will be followed by IN2P3
GGUS TTS support, included LHCOPN part, is moved to WLCG
Internet2
Installing perfsonar-ps in many US T2s and T3s.
Monalisa
Large installed base.
Serving Alice.
ESnet on US tier2s
A increase of traffic between US T2s and European T1s is foreseen. Dedicated links would be better than using the generic IP connectivity as today.
Monitoring Discussion
NL-T1: access to raw data not very useful. status map accessible to all users via grid certificate.
KIT: BGP route checks for change of paths, data transfers.
PIC: E2Emon would be useful. Perfsonar is useful to show the link is not the problem. Not interested in row data. Weather map access should be open.
NDGF: Wish access to raw data. No use of e2emon
FNAL: have measurements, notifications, weathermap for end users, should be service based monitoring and not link based
CNAF: it's useful, access to raw data may be interesting in the future, nagios plug-in for notifications, weather map can be interesting if is very reliable. e2emon is used for debugging.
RAL: as FNAL
IN2P3: performace test important, may not interested in alarms, e2emon is not in use because unreliable.
CERN: perfromannce test, traceroute, alarm, decouple e2emon.
Service level definition
Define response time
How to measure: link capacity, BER
Actions:
John: Complete the SLD
TbD: Take Responsibility for Operations
John: Lead the Operational Conference Calls
Guillaume: follow up GGUS integrations of LHCOPN tickets.
MonWG: define requirments for perfsonar and provide it to Geant.
Next meeting 28-29 June 2010 in Barcelona
Thanks to JANET for hosting the event and for the dinner.
