Dear IPPM (and SPRING) participants,

I'm solliciting interest in a new network monitoring metric which allows to detect and locate congested interfaces. Important properties are

  *   Same scalability as ICMP ping in the sense one measurement relation required per monitored connection
  *   Adds detection and location of congested interfaces as compared to ICMP ping (otherwise measured metrics are compatible with ICMP ping)
  *   Requires Segment Routing (which means, measurement on forwarding layer, no other interaction with passed routers - in opposite to ICMP ping)
  *   Active measurement (may be deployed using a single sender&receiver or separate sender and receiver, Segment Routing allows for both options)

I'd be happy to present the draft in Vancouver. If there's community interest. Please read and comment.
