Info on Ethernet IEEE1588 (Institute of Electrical and Electronics Engineering) PTP (Precision Time Protocol) and PRP (Parallel Redundancy Protocol)
Are IEEE1588/PTP and PRP solely software protocols? Is Ethernet switch IC needed to support these two protocols? The confusion is whether PTP and PRP are hardware- or software-dependent.
Based on the IEEE1588/PTP FAQ(Frequently Asked Questions) document, the IEEE1588 works without special hardware, but not as accurately.
For the rest of the details, go to Question 3 of the IEEE1588 FAQ.
Based on Parallel Redundancy Protocol, PRP can be implemented in software.
Customer plans to implement a new project designing an Ethernet switch card. For this implementation, there is a requirement for PTP and PRP protocols in the module.
