2. 2 Monitoring JANET from photons to flows Demands: From researchers From NOCs/institutions/’power’ users Layer 1, 2, 3 … metrics Routing (BGP/ISIS) – updates/full feed Packet capture data (up to 40Gbps) Flow data Legal requirements RIPA, DPA, private data, ethical behaviour Indivudual vs institutional data & summary vs detail data Research topics in the UK Visualization Signature analysis / DPI Anomaly processing Optical networks/switching Issues: Standards in measurements Standard approach across measurement types Interchange of data between systems Hard to compare measures directly What is a ‘good’ link? Requirements The SuperJANET5 5 th Objective - Network Visibility Steve Williams s.williams@ja.net

3. 3 Monitoring JANET from photons to flows JANET and Research Aim to support and encourage research and assist where possible by providing bandwidth and services that help researchers Assist network research by providing access to the network Need to balance: –operational vs research requirements… –legal vs research requirements Monitoring is research driven

18. 18 Monitoring JANET from photons to flows What was that about sniffing packets Isn’t that interception?

19. 19 Monitoring JANET from photons to flows JANET is a private network –No public/walk in access –Only access to staff/students/bona fide visitors –Breach of RIP by network operations staff is civil case not criminal –Breach by non-operations staff is still criminal (student hackers etc…) –http://www.ja.net/development/legisl ation/laws.htmlhttp://www.ja.net/development/legisl ation/laws.html

20. 20 Monitoring JANET from photons to flows Research access to data Principle of ‘least disclosure’ –No access to data not required –Use anonymisation where possible –Access to full data only in cases where proven case presented –No access to header and payload data –Payload summary data/signatures Researchers agree to and sign policy –Non-disclosure of data –Maintain privacy –Scope of research work This policy works only because JANET is a private network.

23. 23 Monitoring JANET from photons to flows Key issues Architecture of monitoring is key Interchange of data between sytems Stability and comparability of data between locations and across time The legal framework cannot be ignored –Some researchers try… –Some countries have less stringent laws
