Network clock synchronization floating window and window delineation

摘要

A network component comprising at least one processor configured to implement a method comprising initiating a synchronization window, and promoting the transmission of a frame comprising a control symbol, wherein the control symbol delineates a beginning of the frame, and wherein the control symbol is offset from the beginning of the synchronization window. Also disclosed is a system comprising an upstream node in communication with a downstream node, wherein the upstream node transmits a data stream comprising a plurality of frames to the downstream node, wherein the data stream is organized into a plurality of synchronization windows, and wherein the frames float within the synchronization windows. Included is a method comprising transmitting an Ethernet data stream comprising an Ethernet control symbol, wherein the Ethernet control symbol is transmitted within a synchronization window and delineates a start of a packet within the synchronization window.

1. A network component comprising:
a memory coupled to a processor, wherein the memory comprises instructions that cause the processor to:
initiate a synchronization window; andpromote the transmission of a frame comprising a start of frame delimiter (SFD) and a plurality of timeslots, wherein the SFD delineates a beginning of the frame, wherein the synchronization window is initiated using a signal not located within the frame, wherein the frame is floating within the synchronization window, and wherein the beginning of the SFD is not the same as the beginning of the synchronization window.
