摘要： Systems and methods for policing a Quality of Service (QoS) flow in a MoCA network are provided. The network may include a sending node, a receiving node and a network controller. The network controller may allocate a QoS flow between the sending node and the receiving node. The sending node may request bandwidth for the QoS flow from the network controller. QoS requests have a higher priority than some other requests and may swamp the network. The sending node therefore polices its use of the network. First, the sending node computes a policing time period Tpp. Next the sending node computes a packet and bit allocation for the use of the network during a Tpp. Last the sending node sends reservation requests to the network controller when the allocation of packet or bits has not been exceeded. If any allocation has been exceeded the sending node reserves bandwidth via opportunistic reservation requests which have a lower priority than some other requests.

摘要： A method for assessing channel performance in a home communication network is provided. The home communication network is operable over a plurality of channels. The home communication network includes a network controller and a plurality of nodes. Each of the network controller and the plurality of nodes is in communication over a coax backbone. The method preferably includes selecting a channel for assessment and allocating a first probe operation for use with the plurality of nodes. 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.

摘要： A first device coupled to a multimedia over coax alliance (MoCA) network may receive, from a second device, an indication that a configuration button on the second device has been pushed. The first device may receive, from a third device, an indication that a configuration button on the third device has been pushed. The first device may allow the second device to be authenticated on the MoCA network if the configuration buttons of the second and third devices were both pushed within a determined amount of time. The first device may prevent the second device from being authenticated on the MoCA network if the configuration button of the second device and the configuration button of the third device were not pushed within a determined amount of time. The indication from the third device may comprise a layer 2 management entity (L2ME) message or a Protocol Information element.

摘要： Systems and methods for transmitting packets over a network of communication channels are provide. A system according to the invention may include first and second nodes in communication with a coax backbone. The first node may further include a retransmission buffer. The system may also include a network access coordinator operative to coordinate access of the nodes to the coax backbone. In a time period at least one first packet is transmitted by the first node to the second node. The first packet may include an indication that retransmission service is applied. The first packet may also include a indication of the length corresponding to the packet. If, during the first time period the packet is not received by the second node, the second node is operative to send a retransmission request to the network access coordinator.
