System and Method for Reduced Latency Reporting in an Ethernet Passive Optical Network (EPON)

摘要

A system and method for reduced latency reporting in an Ethernet passive optical network (EPON). Gate messages can be generated by a bridged fiber coax unit (FCU) in response to a first report message from a coax network unit (CNU). A second report message including a request for bandwidth can be transmitted to the optical line terminal (OLT) prior to receipt of upstream data at the FCU.

主权项

1. A coax fiber unit, comprising:
a first physical layer device that is configured for communication with a coax network unit via a coaxial cable, wherein the communication includes a receipt of a first report message from the coax network unit, the first report message including a first request for bandwidth for the transmission of first data from the coax network unit; a second physical layer device that is configured for communication with an optical line terminal via an optical cable; and a controller that is configured to initiate a transmission, prior to receiving the first data at the fiber coax unit from the coax network unit via the coaxial cable using bandwidth assigned via a first gate message, of a second report message from the fiber coax unit to the optical line terminal, the second report message including a second request for bandwidth for the transmission of the first data from the fiber coax unit to the optical line terminal.
