The method may also include, in response to the allocating, sending a first probe operation report message from each of the plurality of nodes to the network controller. In response to receiving the first probe operation report messages, the method may further include using the network controller to select a node to be a channel assessment operation node. In addition, the method may include selecting at least a portion of the plurality of nodes to participate in a channel assessment operation signal exchange. The method may also include moving the selected nodes to a different channel to perform a channel assessment operation on the different channel and using the channel assessment operation node to allocate a second probe operation on each of the selected nodes.

Description

    FIELD OF TECHNOLOGY
  • The present invention relates generally to information networks and specifically to transmitting information such as media information over communication lines such as coaxial cable (hereinafter “coax”), thereby to form a communications network.
  • BACKGROUND
  • Home networking over coax is a known technology which has vast commercial potential.
  • Home network technologies having packet aggregation functionality are known generally. The Multimedia over Coax Alliance (MoCA™), at its website mocalliance.org, provides an example of a suitable specification (MoCA 1.0) for networking of digital video and entertainment through existing coaxial cable in the home which has been distributed to an open membership. Packet aggregation functionality is not provided. MoCA 1.0 specification is incorporated by reference herein in its entirety.
  • Home networking over coax taps into the vast amounts of unused bandwidth available on the in-home coax. More than 70% of homes in the United States have coax already installed into the home infrastructure. Many have existing coax in one or more primary entertainment consumption locations such as family rooms, media rooms and master bedrooms—ideal for deploying networks. Home networking technology allows homeowners to utilize this infrastructure as a networking system and to deliver other entertainment and information programming with high QoS (Quality of Service).
  • The technology underlying home networking over coax provides high speed (270 mbps), high QoS, and the innate security of a shielded, wired connection combined with state of the art packet-level encryption. Coax is designed for carrying high bandwidth video. Today, it is regularly used to securely deliver millions of dollars of pay per view and premium video content on a daily basis. Home networking over coax can also be used as a backbone for multiple wireless access points used to extend the reach of wireless network throughout a consumer's entire home.
  • Home networking over coax provides a consistent, high throughput, high quality connection through the existing coaxial cables to the places where the video devices currently reside in the home without affecting the existing analog or digital services present on the cable. Home networking over coax provides a primary link for digital entertainment, and may also act in concert with other wired and wireless networks to extend the entertainment experience throughout the home.
  • Currently, home networking over coax works with access technologies such as ADSL and VDSL services or Fiber to the Home (FTTH), that typically enter the home on a twisted pair or on an optical fiber, operating in a frequency band from a few hundred kilohertz to 8.5 MHz for ADSL and 12 MHz for VDSL. As services reach the home via xDSL or FTTH, they may be routed via home networking over coax technology and the in-home coax to the video devices. Cable functionalities, such as video, voice and Internet access, may be provided to homes, via coaxial cable, by cable operators, and use coaxial cables running within the homes to reach individual cable service consuming devices locating in various rooms within the home. Typically, home networking over coax type functionalities run in parallel with the cable functionalities, on different frequencies.
  • The coax infrastructure inside the house typically includes coaxial wires and splitters. Splitters used in homes typically have one input and two or more outputs and are designed to transfer signals from input to outputs in the forward direction, or from outputs to input in the backward direction and to isolate splitter outputs and prevent signals from flowing room/outlet to room/outlet. Isolation is useful in order to a) reduce interference from other devices and b) maximize power transfer from Point Of Entry (POE) to outlets for best TV reception.
  • The MoCA technology is specifically designed to go backwards through splitters (insertion) and go from splitter output to output (isolation). All outlets in a house can be reached from each other by a single “isolation jump” and a number of “insertion jumps”. Typically isolation jumps have an attenuation of 5 to 40 dB and each insertion jump attenuates approximately 3 dB. MoCA has a dynamic range in excess of 55 dB while supporting 200 Mbps throughput. Therefore MoCA can work effectively through a significant number of splitters.
  • MoCA is a managed network unlike some other home networking technologies. It is specifically designed to support streaming video without packet loss providing very high video quality between outlets.
  • Digital cable programming is delivered with threshold Packet Error Rate (PER) of below 1e-6. The home network should preferably have similar or better performance so as not to degrade viewing.
  • Later versions of the MoCA specification may require or permit that a MoCA device transmit and receive on more than one channel. For the purposes of this application the term “channel” should be understood to refer to an operational frequency upon which a MoCA network can operate.
  • The disclosures of any publications and patent documents mentioned in the specification, and of the publications and patent documents cited therein directly or indirectly, are hereby incorporated by reference.
  • SUMMARY OF THE INVENTION
  • A system and/or method channel assessment in a communications network, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • The objects and advantages of the invention will be apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
  • FIG. 1 shows a schematic diagram of an illustrative single or multi-chip device that may be used in accordance with principles of the invention; and
  • FIG. 2 shows illustrative steps of a process in accordance with the principles of the invention.
  • DETAILED DESCRIPTION OF THE INVENTION
  • Apparatus and methods for channel assessment in a communication network are provided. In some embodiments, the apparatus and methods may move a node from a first channel to a second channel to assess performance of the node on the second channel. The performance may be dependent on noisiness of the node on the second channel.
  • Some embodiments may involve “Another Channel Assessment,” which is a procedure that allows nodes to move to another channel for interference detection or expected performance assessments.
  • A channel assessment operation (“CAO”) may be triggered by an application that is external to a network controller (“NC”). The CAO may be managed and scheduled by the NC. The NC may gather channel assessment results. In certain embodiments, the CAO may be identified in a Media Access Plan (“MAP”) as a link state.
  • The channel assessment results may include information regarding noise conditions on each node input and full mesh rate for each node on each channel. The channel assessment results may also provide an estimation of the achievable capacity in the assessed channel.
  • The channel assessment results may be accessible by a higher layer application. The results may include for each node and channel information regarding noise measured or estimated for each channel at each of the nodes. The information may include MoCA Probe0 information. MoCA Probe0 information corresponds to a period of time on the network when none of the nodes transmit information. It is a silent probe and, to reiterate, all nodes in the network preferably do not transmit during this silent probe. Rather, it is a period of time in which each node measures the existing noise on the network from the respective node's perspective.
  • The higher layer application may decide whether to initiate a transfer from one channel to another channel. The higher layer application may assess the whole band—i.e., each operational frequency available to the network—to determine an optimal channel for the implementation of the higher layer application's network. Once channel assessment results are available for the application, it may decide to move the network to another channel. Illustrative reasons to move the network to another channel include:
  • 1. The performance on the current channel is not sufficient to provide the required throughput due to either large attenuations or some RF ingress interference.
  • 2. Moving the network to another channel is required to improve the performance further or reduce aggregated transmission power by moving to a channel that has better noise and attenuation conditions.
  • 3. A new node that joined the network reduces significantly the network aggregated throughput, or is creating some unusable channels.
  • Illustrative embodiments of apparatus and methods in accordance with the principles of the invention will now be described with reference to the accompanying drawings, which form a part hereof. It is to be understood that other embodiments may be utilized and structural, functional and procedural modifications may be made without departing from the scope and spirit of the present invention.

The “system” may include one or more of the features of the apparatus that are shown in FIG. 1 and/or any other suitable device or approach. The “system” may be provided by an entity. The entity may be an individual, an organization or any other suitable entity.
  • FIG. 2 shows illustrative channel assessment process 200. Process 200 may send Type 0 Probe to bit mask nodes, Request and Receive Type 0 Probe Report, Send Type I Probe to bit mask nodes, and Receive Type I Probe Report from each other node. The process may be repeated for some or all of the other nodes.
  • Type 0 probe is a time period in which all nodes of a network, and in some embodiments a subset of the network, are quiet. Type 0 probe may be used for detecting the existence of interference or another network (Beacon detecting) by the assessing node.
  • In some embodiments, a channel assessment operation may proceed as follows:
  • (1) NC selects a channel for assessment;
  • (2) NC allocates a “Probe-0” operation for all nodes or a list of nodes;
  • (3) All nodes that participated in (2) send Probe 0 report message to the NC;
  • (4) NC may select a node to be a “CAO node” (based on the reported Probe-0 results) and a list of nodes that may or must participate in the CAO signal exchange, or go back to (1);
  • (5) Selected nodes move to the selected channel to perform CAO Probe 1 where the CAO transmits Probe 1 message to all other nodes;
  • (6) NC selects the next node to be the CAO node and the process in (4) and (5) is repeated;
  • (7) All nodes that participated in the CAO process send their calculated full mesh rate (“FMR”) on the assessed channel to the NC, using CAO probe 1 report; and
  • (8) NC may select another channel for assessment and go back to (1).
  • In some embodiments, the following factors may be considered in connection with a transition from one channel to another channel:
  • 1. NC MUST allocate a Transition Time for a node to move to another channel (Tlo ˜100 uSec).
  • 2. During this time transmission on the current channel can continue.
  • 3. After Tlo and until the allocated time for the Probe0 operation and Type I Probe operation NC should preferably not allocate any transmission opportunity on the current channel.
  • 4. One CAO step should preferably follow a full link maintenance operation (“LMO”) procedure.
  • In some embodiments, messages may be used in connection with channel assessment. Illustrative messages include:
  • 1. “Probe0_for_channel_Assessment_Report”
  • NC may use this command to schedule a node to send a Probe 0 report on the assessed channel.
  • 2. “FMR_for_channel_Assessment_Report”
  • NC may use this command to schedule a node to send a Full Mesh Rates per the assessed channel.
