| 摘要 |
A power line communications system that facilitates the provision of differentiated data services is provided. One embodiment of the present invention may include tagging downstream data at an ingress point, such as a point of presence or aggregation point. The tagging of data packets may allow the power line communication network elements such as backhaul points, bypass devices, and repeaters to determine the data type and class of service of each data packet and may allow the network elements to prioritize, queue and transmit the data packets accordingly. Such queuing may employ the use of multiple queues with some queues having different sizes and different weight factors from other queues.
