Abstract
Aspects of a method and system for compensated time stamping for time-sensitive network communications are provided. In this regard, one or more timestamps generated in an OSI layer above the physical layer may be adjusted based on parameters associated with an amount of time in which data traverses a PHY of the network device. Communications of the network device may be managed based on the adjusted one or more timestamps. The parameters may comprise one or more of: average ingress PHY traversal time, average egress PHY traversal time, variance of ingress PHY traversal time, and variance of egress PHY traversal time. One or more network links coupled to the network device may be characterized based on the one or more adjusted timestamps. The parameters may be stored in one or more registers within a PHY of the network device.
