  • 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

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

  • What was that about sniffing packets
  • Isnt that interception?

19
  • 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)

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.

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
