I am trying to implement a quality of service policy such that old data is
not forwarded to the application that is to set a life span. All the ECU's
in the network which are providers or consumers are connected via CAN and
all have to be synchronized to some master clock because there is a
Publish/Subscribe pattern in the communication protocol. So all data sent
and received should have timestamps and then after the time sync mechanism,
I can compare current time with the timestamps and drop data when specified
lifespan expires. Hope you understood. I saw a mechanism which sends SYNC
and FollowUp messgaes to provide time sync but I need an implementation.
Kindly let me know.
