Abstract
The time accuracy of the Precision Time Protocol deteriorates in consequence to Delayreq/Delayresp session collisions common for applications using shared broadcast media. In this paper we propose a protocol that coordinates Delay_req/Delay_resp sessions with minimum changes to the original PTP protocol. Simulations illustrate protocol´s operation and demonstrate significant reduction of session collisions.
