  1. REST Style Large Measurement Platform Protocol draft-liu-lmap-rest-00.txt Dapeng Liu(Presenter) Lingli Deng China Mobile Shihui Duan CATR Cathy Li China Cache

  2. Outline • REST Style LMAP Protocol • Control Protocol • Configuration Update • Instruction Assignment • Capacity and Status Feedback • Report Protocol • Running code & Deployment Case

  3. Background • LMAP Use Cases • LMAPcanbeusedtomonitornetworkquality • IDCserviceMonitor/VIPcustomermonitor • LMAPcanbeusedtooptimizeuserexperience • CDNaccelerationeffect • Network operation and maintenance • Enterprisenetwork • draft-liu-lmap-rest-00 defines a REST style LMAP protocol • Include both control and report protocol

  4. Motivation • Why Use REST Style HTTP? • REST: Representational State Transfer • Benefit of using REST • One of the best practices of using HTTP • Simple • Stateless • Clean design • Scalable …

  5. REST Style Example • HTTP GET: • List the URIs and perhaps other details of the collection's members. • HTTP POST • Create a new entry in the collection. The new entry's URI is assigned automatically and is usually returned by the operation. • PUT • Replace the entire collection with another collection. • DELETE • Delete the entire collection. Reference: http://en.wikipedia.org/wiki/Representational_state_transfer

  6. Rest Style LMAP Control Protocol • Configuration Update from Controller to MA • PUT /ma/config/ • Update the configuration from controller to MA • JSON format parameters • Align with LMAP information model

  7. MA agent ID MA control tasks MA control channels MA control schedule

  8. Instruction Assignment from Controller to MA • POST /ma/ins/ • Send measurement instruction from controller to MA • JSON format parameters • Align with LMAP information model

  9. MA suppression MA task MA schedule MA channel

  10. Capability and Status Feedback from MA to Controller • GET /ma/capabilities • Get MA capablitlites • GET /ma/failure • Get failure information • Get /ma/logging • Get logging information

  11. Response of get capabilities Ma capabilities information

  12. Response of get failure information Response of get logging information

  13. Report Protocol • POST /collector/report/ • JSON format parameters • Align with LMAP information model
