2nd RINASim Webinar

  1. 1. RINASim ● MECHANISMS AND POLICIES ● Vladimír Veselý and Marcel Marek Brno University of Technology, Czech Republic veselyv@fit.vutbr.cz University of Oslo, Norway marcelma@ifi.uio.no @ictpristine Webinar, 27th February 2017 1
  2. 2. Agenda 1) Introduction 2) Mechanism and Policy framework 3) Demonstrations  Flow Allocator  EFCP 4) Conclusion @ictpristine Webinar, 27th February 2017 2
  3. 3. @ictpristine Webinar, 27th February 2017 3 1) Introduction Current state
  4. 4. Status Quo  February 2017 release  GitHub repository https://github.com/kvetak/RINA/releases/tag/February2017  CDAP API  OMNeT++ 5.1 technical candidate compatibility  Code refactoring @ictpristine Webinar, 27th February 2017 4
  5. 5. Virtual Machine  Out-of-the box virtual machine  OMNeT++ 5.0 with the newest RINASim  Download from http://nes.fit.vutbr.cz/ivesely/vm/RINASim.zip  OVA appliance of MintLinux created on VMWare Workstation  …should work also on VirtualBox and Qemu  Custom highlighter of code syntax @ictpristine Webinar, 27th February 2017 5
  6. 6. Reporting Issues  Report on https://github.com/kvetak/RINA/issues  Resolution rate will improve…hopefully  @ictpristine Webinar, 27th February 2017 6
  7. 7. @ictpristine Webinar, 27th February 2017 7 2) Mechanism and Policy Design notes A long road from idea/spec towards FSM Coding conventions
  8. 8. Difference  Mechanism  Fixed  Cannot be changed  E.g., error checking on data-link layer  Policy  Flexible  Can be negotiated  E.g., CRC-32, CRC- 64, Vitrebi @ictpristine Webinar, 27th February 2017 8
  9. 9. Explicit vs. Implicit Policies  RINA specs cover explicit policies  data processing (e.g., how is PDU handled by EFCP and RMT)  control processing (e.g., flow allocation and deallocation procedures)  Implicit policies  do not have strict placeholder  variable inputs and outputs  E.g., routing or secured enrollment @ictpristine Webinar, 27th February 2017 9
  10. 10. Defining Policy  Policy is (a set of) algorithm(s)  Properties  Deterministic  Closed control (beaware of recursion)  Finite (avoid state explosion)  Known inputs and outputs  Description  Formal: finite-state machines  Implementation: C++ class @ictpristine Webinar, 27th February 2017 10
  11. 11. FA @ictpristine Webinar, 27th February 2017 11 Allocate Request M_CREATE(flow) Deallocate Request NewFlowRequestPolicy Null Is malformed? Create FAI true / send negative allocate response false FAI successfully created / pass allocate request to FAI Map QoS to RA s Qos-cubes Has resources to honor QoS? Has access rights? true true policy succeeded / return positive result policy failed / return negative result false false Is dst AP local? Create FAI hopCount == 0 FAI successfully created / pass allocate request to FAI false / hopCount-- true false / forward M_CREATE(flow) true / send negative M_CREATE_R(flow) / pass deallocate request to FAI policy invoked
  12. 12. FAI @ictpristine Webinar, 27th February 2017 12 Allocate Request Degenerate Data Transfer M_CREATE_R(flow) AllocateRetryPolicy AllocateNotifyPolicy Instantiated Is dst AP local? Is policy acceptable? Create EFCPI Create bindings false / invoke NewFlowRequestPolicy true / pass allocate request to dst AP false / invoke AllocateNotifyPolicy true bindings successfully created / send M_CREATE(flow) && invoke AllocateNotifyPolicy EFCPI successfully created Is response positive? Establish IPC between local APs Create bindings false / invoke AllocateNotifyPolicy bindings successfully created / invoke AllocateNotifyPolicy establishment successful Is response positive?
