摘要:
Systems and methods according to these exemplary embodiments provide for mechanisms and methods that allow for improving the efficiency of a passive optical network (PON). Upstream data transmission can occur by allowing an optical network unit (ONU) cycle to overlap more than one GPON transmission convergence (GTC) frame. Additionally, or alternatively, multiple different bandwidth maps can be transmitted per dynamic bandwidth allocation (DBA) cycle to inform ONUs of their respective, upstream bandwidth allocations.
摘要:
An optical access network (5) comprises optical network units (10) connected to a node (40). A monitoring unit (35) determines information indicative of energy consumption at the optical network unit (10) over a period of time. An optical network unit (10) can operate in operating states/modes which differ in their energy consumption. Monitoring unit (35) can determine the information by determining a time that an optical network unit spends in the different operating states/modes. Monitoring unit (35) can use a state machine (31) at the node (40) which represents the optical network unit (10). An optical network unit (10) can locally record time spent in states/modes and forward this to the monitoring unit (35). An optical network unit (10) can locally monitor energy consumption and forward this to the monitoring unit (35). An operational parameters of the access network (5) can be modified based on the information determined by the monitoring unit (35).
摘要:
Power management is performed in an optical access network to reduce energy consumption. Service information is determined about traffic at the first node. Power management is controlled based on the determined service information. The first node can control power management at the first node and/or the second node. The first node can categorize traffic according to service and determine traffic activity per service. Service information can include service type of the traffic, traffic class of the traffic, and/or quality of service requirements of the traffic.
