Quick Recap

  • A measurement endpoint interface design unifying access to different

end host based measurement platform

  • e.g. CAIDA ark, ICSI Netalyzr, RIPE Atlas … etc.
  • PacketLab endpoint ≈ VPN endpoint with network measurement

support

  • Experiment logic relocated to experimenter side

Quick Recap

  • Access control/delegation?
  • Certificates
  • Endpoint fine-grain control?
  • Monitors

Where We Are Now

  • Basic endpoint implementation
  • pktlab C library
  • Message, time, byte order utilities
  • pyPL – Python wrapper for C library
  • Filled in some missing design pieces
  • Endpoint virtual memory layout
  • Security between endpoint and controller
  • Fields in each certificate
  • Message protocol

Today’s Demo

  • pl_ping, pl_dig
  • Respective tools modified to use PacketLab endpoint “sockets”

Demo in Action!!

  • pl_ping
  • ping from different endpoint to 8.8.8.8 and see latency
  • pl_dig
  • DNS query from different endpoint to 8.8.8.8 and see query time

Endpoint?

  • No changes to endpoint for both pl_ping, pl_dig!
  • Endpoint already done when doing pl_ping, pl_dig
  • No cost to endpoint operator for new experiments!

Some Problems - Still Exploring

  • Usability vs Simplicity
  • More or less “transport layer” socket types?
  • Sharing model
  • Allow sharing of endpoint at the same time?
  • Suspend and resume of connection (with priority)?
  • Preemption?
  • Other operation modes
  • Relay mode
  • Direct endpoint connect mode
  • Short lived experiment mode
  • Approach: come up with new experiments and see impact of design

3 Months 6 Months Now 9 Months 12 Months

Basic Cont’d

  • 1. Raw socket impl.
  • 2. Trans-socket

design & impl.

Sharing

  • Sharing model

design and impl.

Monitor and Filter

  • Monitor & filter

design and impl.

Certificates

  • 1. Certificate design

and impl.

  • 2. Rendezvous

server impl.
