Abstract

Abstract 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.

Claims Analysis

Total Claims: 20

Claim 1

Independent Claim 208 words

A method of communicating data packets over one or more power lines wherein a first medium voltage (MV) access device is coupled to a medium voltage power line and provides communication services to one or more user devices at one or more customer premises, comprising: receiving the data packets from the one or more user devices at the first MV access device; determining a data type for the data packets with the first MV access device; tagging the data packets with priority information based on the data type with the first MV access device; placing each of the data packets in one of a plurality of queues based, at least in part, on the data type of the data packets with the first MV access device; selecting a data packet for transmission from one of the plurality of data packet queues with the first MV access device; transmitting, from the first MV access device, the tagged data packets over the MV power line according to said selecting; receiving the tagged data packets transmitted by the first MV access device at a second device connected to the MV power line; and transmitting the received tagged data packets from the second device without tagging the data packets with priority information.

Claim 2

Independent Claim 208 words

Claim 3

Dependent Claim 21 words

The method of claim 1 , wherein said determining the data type is based on an address of the data packets.

Claim 4

Dependent Claim 17 words

The method of claim 1 , further comprising rate limiting at least some of the data packets.

Claim 5

Dependent Claim 20 words

The method of claim 3 , wherein the rate limiting is based on the data type of the data packets.

Claim 6

Dependent Claim 19 words

The method of claim 3 , wherein said rate limiting is based, at least in part, on subscriber information.

Claim 7

Dependent Claim 23 words

The method of claim 1 , wherein said placing the data packets is based upon a priority value associated with the data packet.

Claim 8

Dependent Claim 34 words

The method of claim 1 , wherein said receiving the data packets at the first MV access device comprises receiving the data packets over a communication link that includes a low voltage power line.

Claim 9

Dependent Claim 19 words

The method of claim 1 , wherein at least some of the plurality of queues are different in size.

Claim 10

Dependent Claim 31 words

The method of claim 1 , wherein said receiving the data packets at the first MV access device comprises receiving the data packets over a link that includes a wireless link.

Claim 11

Dependent Claim 33 words

The method of claim 1 , further comprising mapping a first priority according to a first communication protocol associated with the data packets to a second priority associated with a second communication protocol.

Claim 12

Dependent Claim 25 words

The method of claim 1 , wherein a first data type comprises voice data packets, the method further comprising rate limiting the voice data packets.

Claim 13

Independent Claim 207 words

A method of providing communications in a power line communications system, comprising: at a downstream device: determining a data type for upstream data packets; tagging the upstream data packets with first priority information based, at least in part, on the data type; prioritizing transmission of the upstream data packets based, at least in part, on the first priority information of the data packets; and transmitting the upstream data packets according to said prioritizing; and at an upstream device: determining a data type for downstream data packets; tagging the downstream data packets with second priority information based, at least in part, on the data type; prioritizing transmission of the downstream data packets based, at least in part, on the second priority information of the data packets; and transmitting the downstream data packets according to said prioritizing; and at an intermediate device disposed in a communication path between said downstream device and said upstream device: receiving upstream data packets communicated through the downstream device; prioritizing upstream data packets based, at least in part, on the first priority information of the upstream data packets; and transmitting the received upstream data packets in accordance with said prioritizing of the upstream data packets without tagging the upstream data packets with priority information.

Claim 14

Independent Claim 207 words

Claim 15

Dependent Claim 78 words

The method of claim 12 , further comprising: at the intermediate device disposed in a communication path between said downstream device and said upstream device: receiving downstream data packets communicated through the upstream device; prioritizing the downstream data packets based, at least in part, on the second priority information of the downstream data packets; and transmitting the downstream data packets according to said prioritizing by the intermediate device and without tagging the downstream data packets with priority information.

Claim 16

Dependent Claim 14 words

The method of claim 12 , wherein the upstream device comprises an aggregation point.

Claim 17

Dependent Claim 16 words

The method of claim 12 , wherein the downstream device comprises a medium voltage access device.

Claim 18

Dependent Claim 52 words

The method of claim 12 , wherein prioritizing by the downstream device comprises: placing each of the upstream data packets in one of a plurality of queues based, at least in part, on the data type; and selecting a data packet for transmission from one of the plurality of data packet queues.

Claim 19

Dependent Claim 14 words

The method of claim 12 , wherein the upstream device comprises point of presence.

Claim 20

Dependent Claim 33 words

The method of claim 12 , wherein determining a data type for upstream data packets comprises determining an address of the upstream data packets and determining a data type associated with the addresses.
