Abstract: An LDPC parity check matrix includes a systematic portion having a plurality of systematic elements and a parity portion having a plurality of parity elements. The value of each systematic element determines a cyclic shift to be applied to rows of an identity submatrix corresponding to that element. The value of each parity element determines a cyclic shift to be applied to rows of an identity submatrix corresponding to that element. The weights of two or more columns of the parity portion are the same.

Abstract: Systems and methods are disclosed for securing a network, for admitting new nodes into an existing network, and/or for securely forming a new network. As a non-limiting example, an existing node may be triggered by a user, in response to which the existing node communicates with a network coordinator node. Thereafter, if a new node attempts to enter the network, and also for example has been triggered by a user, the network coordinator may determine, based at least in part on parameters within the new node and the network coordinator, whether the new node can enter the network.

Abstract: Methods and systems are provided for enhanced communication capabilities discovery in managed networks. A network controller network node in a network may receive from a first network node a request for information regarding communication capabilities of one or more other network nodes; may obtain in response to the request communication capabilities related information corresponding to the one or more other network nodes; and may send the obtained communication capabilities related information to a second network node. In some instances, at least some of the communication capabilities related information may be obtained directly from one of the one or more network nodes. In some instances, at least some of the communication capabilities related information may be obtained based on broadcast of requests by the network controller network node to all network nodes. The network controller network node may store information relating to discovered communication capabilities of all network nodes.

Abstract: Various embodiments of methods and systems for pausing and shaping data flow while supporting both parameterized and prioritized Quality of Service are disclosed. In some embodiments, a system for pausing and shaping data flow comprises an input buffer, a first pause controller coupled to the input buffer and an output buffer for flow control messages. Various embodiments also include a hop-1 buffer coupled to the input buffer and a hop-2 buffer comprising a plurality of queues coupled to the hop-1 buffer. Additionally, in some embodiments, a second pause controller is coupled to the queues. The second pause controller selects a queue or queues that will cause a pause to be generated based on a predetermined condition. A two-hop process controller controls the data packet flow from the input buffer to the hop-1 buffer and from the hop-1 buffer to the hop-2 queues based on packet classification.

Abstract: Methods and systems are provided for Layer 2 (L2) discovery in a managed shared network, such as a Multimedia over Coax Alliance (MoCA) network. A network controller node of the MoCA network node may receive, from a node entering the MoCA network, a submission requesting discovery of information regarding communication capabilities of a plurality of nodes in the network. In response to the request, the network controller node may obtain from one or more nodes of the plurality of nodes information regarding communication capabilities of the plurality of nodes, and may send the communication capabilities of the plurality of nodes, such as to a second plurality of nodes.

Abstract: The disclosed method and apparatus provides systems, methods, and apparatuses for implementing a PQoS flow between two or more nodes located in different network segments of a multi-segment network, when some nodes involved in the flow lack support for high layer QoS management protocols. Specifically, some embodiments are directed toward implementing a PQoS flow involving some nodes that lack network layers higher than a Data Link Layer (layer 2). For example, some embodiments of the current disclosed method and apparatus can create a parameterized QoS flow between a source node and a destination node when at least one of the nodes participating in the flow (i.e. the source node, one or multiple bridge nodes that the QoS flow passes, and the destination node) lacks UPnP QoS Device Services (i.e., a higher layer QoS management protocol).
