Internet2 Network Observatory Update Matt Zekauskas, Measurement SIG 2006 Fall Member Meeting 4-Dec-2006

Matt Zekauskas2 Note… There is a main track session on the Observatory Wednesday morning This will be my take, and an opportunity for you to ask questions and give comments

Matt Zekauskas3 Recall: Abilene Observatory Motivation Monitor network operations Support network research Two components Data collected by NOC, OHIO ITEC, and Internet2 for operations and research, stored in distributed databases Equipment colocation where uniquely useful for research projects [allocate power and space ahead of time]

Matt Zekauskas4 Abilene Observatory: Capabilities One way latency, jitter, loss IPv4 and IPv6 (“owamp”) Regular TCP/UDP throughput tests – ~1 Gbps IPv4 and IPv6; On-demand available (“bwctl”) SNMP Octets, packets, errors; collected 1/min Flow data Addresses anonymized by 0-ing the low order 11 bits Routing updates Both IGP and BGP - Measurement device participates in both Router configuration Visible Backbone – Collect 1/hr from all routers Dynamic updates Syslog; also alarm generation (~nagios); polling via router proxy

Matt Zekauskas5 Abilene Observatory: Datasets Usage Data Netflow Data Routing Data Latency Data Throughput Data Router Data Syslog Data

Matt Zekauskas6 Abilene Observatory: Rack Hardware Local rack LAN switch 2 PC’s with direct gigE attach to routers for throughput testing 1 PC for latency testing 1 PC for dynamic 1 PC for statistics collection (netflow redistribution, routing, …) – collect locally in case of network partition

Matt Zekauskas7 Abilene Observatory: Collocation PlanetLab NLANR MNA OCxMON NLANR MNA AMP High-speed TCP testing and protocol development

Matt Zekauskas8 Rough Timeline Started thinking about what a new Observatory might mean a while ago, focusing on measuring “lightpaths”; HOPI Small group (Magorian, Metzger, Boote, Boyd Zekauskas) came up with initial thoughts (~June 2006) Languished due to other commitments and NTAC development Proceed with something reasonable for initial Internet2 Network node deployment

Matt Zekauskas9 Internet2 Network Observatory Goals Maintain Abilene Observatory features Keep current data collection going (and in fact we want latency and throughput testing maintained throughout transition to monitor) Keep current testing to middle available Take advantage of newer processors and buses now available AC power helps! 10 G capabilities Incorporate what we learned from HOPI Control/test/measurement Flexibility to update configuration, software based on experience, community input, research input Not so complex as to be unmanageable

Matt Zekauskas10 Internet2 Network Observatory Initial realization Router nodes Same number of machines as Abilene Different interconnection, more powerful LAN switch, 10GE router attachment Optical nodes Same number of machines as HOPI But connect to the Ciena CD CI

Matt Zekauskas11 Router Nodes

Matt Zekauskas12 Optical Nodes

Matt Zekauskas13 Internet2 Observatory: Collocation PlanetLab – new machines to be deployed (were to be upgraded anyway) Passive: in discussion with CAIDA (Matt Z to go back, given that there is now a timeline) AMP project has apparently ended, so it will not continue Adding a Phoebus PC at router sites Adding NetFPGA capability at optical sites

Matt Zekauskas14 Next Steps As always, respond to suggestions If there is a particular aspect you are interested in, let us know! Revisit requirements document from June (see next talk) Review/direction from NTAC, possible WG NOC adding basic performance monitoring for optical nodes Internet2+NOC adding perfSONAR interfaces
