Ethernet Precision Time Protocol (PTP) and Parallel Redundancy Protocol(PRP)

Jump to solution

Hi,

For my new project I am designing an Ethernet switch card. For that there is a requirement for PTP and PRP protocols in the module. I am in serious confusion among these two protocols. I need to clarify whether PTP and PRP are purely software protocol or I need to choose an Ethernet switch IC which supports these two protocols. The confusion is whether PTP and PRP are hardware or software dependent.

Regards

Hafiz

Hi HafizHaja,

Thank you for posting in Wired Communities. You may refer to FAQ about IEEE 1588

IEEE 1588 (PTP) can work without special hardware but not as accurately. I would suggest you to go through FAQ for more information:

https://www.intel.com/content/dam/www/public/us/en/documents/faqs/ieee1588-faq.pdf

For the PRP, as stated in Wikipedia* https://en.wikipedia.org/wiki/Parallel_Redundancy_Protocol Parallel Redundancy Protocol - Wikipedia (*Note: this is third party website in which Intel has no control over the content, extracted the information here for your reference only)

"PRP can be implemented entirely in software, i.e. integrated in the network driver." Please refer to the link for more information.
