Technical Paper Abstract
Time Sensitive Networks standards are being considered for adoption by ODVA into EtherNet/IP. This paper will provide a status and update to the ODVA community on the underlying TSN groundwork being done by other standards groups, and the potential impacts of this work on EtherNet/IP.
- Review the current TSN standards status in IEEE,
- Review the work in IETF DETNET to create wide-area deterministic networks
- Review the work of Avnu developing interoperability and certification standards for TSN, including the Theory of Operations for TSN, a systems design document.
- Review current ODVA SIG activities in response to new TSN technologies.
The paper will review the standard status and content that make up IEEE 802.1 TSN, especially:
- IEEE 802.1Qcc Stream Reservation Protocol (SRP) Enhancements and Performance Improvements;
- IEEE 802.1Qbv Enhancements for Scheduled Traffic;
- IEEE 802.1Qbu Frame Preemption;
- Precision Time (IEEE1588 and IEEE802.1AS)
This paper provides a summary for the following TSN standards:
- IEEE 802.1Qci Per-stream filtering and policing;
- IEEE 802.1CB Frame Replication and Elimination for Reliability;
- IEEE 802.1Qca Path Control and Reservation;
Finally, this paper discusses how EtherNet/IP and TSN standards might combine to provide a new generation of “standard, unmodified, Ethernet” with features and capabilities not previously achievable.
