Abstract

A device for transmitting data to a network includes a source subsystem and a communication subsystem. The source subsystem generates a first data packet that includes first timing information that is based on a time that the first data packet is generated. The first timing information is generated responsive to a first timing generator included in the source subsystem. The communication subsystem is coupled to the source subsystem via one or more abstraction layers and is configured to modify the first data packet to generate a modified data packet for transmission to the network. The modified data packet includes the first timing information and second timing information that is based on a time that the modified data packed is transmitted. The communications subsystem includes a second timing generator that is linked to the first timing generator through the one or more abstraction layers to generate the second timing information.
