PRE-EMPTION IN PASSIVE OPTICAL NETWORKS

摘要

A device for pre-emption in passive optical networks may include a first media access control (MAC) module configured to receive a first type of data traffic and transmit the first type of data traffic to a MAC merge module. The device may further include a second media access control (MAC) module configured to receive a second type of data traffic and transmit the second type of data traffic to the MAC merge module. The device may further include the MAC merge module configured to receive the first and second types of data traffic from the first and second MAC modules, respectively, and provide the first and second types of data traffic for transmission over a port. The MAC merge module may be configured to pre-empt the transmission of the first type of data traffic over the port in favor of the second type of data traffic.

主权项

1. A method for pre-emption in a passive optical network, the method comprising:
transmitting a first type of data traffic to a passive optical network over a common port; pre-empting transmission of the first type of data traffic over the passive optical network in response to detecting a presence of a second type of data traffic; transmitting the second type of data traffic to the passive optical network over the common port; and resuming the transmission of the first type of data traffic to the passive optical network over the common port upon completion of transmitting the second type of data traffic.
