Patent ID: 8295312

Claim:
A method for networking, the method comprising: performing by one or more circuits in a network device, one or more functions comprising: adjusting one or more timestamps generated in an OSI layer above the physical layer based on parameters associated with an amount of time in which data traverses a physical layer device (PHY) of said network device, wherein said parameters are stored in one or more registers within a PHY of said network device; and managing communications of said network device based on said adjusted one or more timestamps, wherein: said parameters 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; and one or both of said variance of egress PHY traversal time and said variance of ingress PHY traversal time are based on PHY traversal time for different configurations of a PHY within said network device.
