Ethernet passive optical network over coaxial (EPoC) system rate mechanism

摘要

An Ethernet passive optical network over coaxial (EPOC) system rate mechanism. A network device is provided that includes a physical layer device (PHY) that is configured for coupling to a coaxial cable, a medium independent interface that facilitates data transmission at 10 Gbit/s or greater, and a reconciliation sublayer that is coupled to the PHY via the medium independent interface. The reconciliation sublayer has a codeword detector that is configured to detect a reserved codeword that is received from the PHY over the medium independent interface. The codeword detector can be configured to forward a rate control signal to a media access control (MAC) based on the detection of the reserved codeword.

1. A network device, comprising:
a physical layer device, deployed as an intermediary between a first network and second network, configured for coupling to a coaxial cable of the first network; a medium independent interface that facilitates data transmission at 10 Gbit/s or greater via the second network; and a reconciliation sublayer, coupled to the physical layer device via the medium independent interface, comprising a codeword detector configured to:
detect a reserved codeword received from the physical layer device over the medium independent interface,forward a rate control signal to a media access control device based on the detection of the reserved codeword to alert the media access control device of an adjustment to a rate of transmission of data from the media access control device to the physical layer device.
