Hi all, I have a DPDK app that requires tight time synchronization between end hosts. In my setup, the testbed is connected to a Cisco switch that supports the PTP protocol. I know that the ixgbe driver for Intel 82599 nics support the PTP time protocol, but I'm not sure if the DPDK framework supports PTP.
I found code in the dpdk tree for IEEE 1588 here, http://www.dpdk.org/browse/dpdk/tree/app/test-pmd/ieee1588fwd.c But I'm not sure what'st the best model to incorporate this functionality. Should I run two DPDK apps (and have flow director rules setup for PTP packets?) or should I just modify my app to support the 1588 functionality. If someone has used/tested the 1588 implementation in the DPDK code base, please let me know. Thanks! Malveeka
