摘要: System and methods are provided for admission to networks that include at least one node providing network coordinator functions. A network coordinator may have a random number generator, with the network coordinator distributing a random number within a network that include at least a first node and a second node. The network coordinator may receive a request for a dynamic encryption key from the first node, with the request being encrypted using a static encryption key unique to the first node, and with the static encryption key being determined based on the distributed random number. The network coordinator may then send a dynamic encryption key to the first node, with the dynamic encryption key being encrypted using the static encryption key. The second node may then admit the first node into the network. The network may be a Multimedia over Coax Alliance (MoCA®) network.

摘要: A network-capable device is configured to: automatically detect the presence of a MoCA network (or other network, depending on the network protocol in the application environment), and configure itself for communication on that network at the appropriate communication frequencies. The network-capable device can be configured to create a new network (e.g., a new MoCA network) if there is no network broadcast signal within a band. Preferably, the network-capable device requires little or no user intervention to configure itself for operation at network operating frequencies or to create a new network where none is detected.

摘要: The use of traffic flag symbols allows a large number of CPEs to transmit traffic notifications to a network controller. In some such embodiments, hundreds of CPEs simultaneously transmit traffic flags on different subcarriers of a channel. For example, in a MoCA2 based access network, up to 480 CPEs can transmit flags in only 5 μs in the 100 MHz-wide channel.

摘要: System and methods are provided for admission in a network comprising at least one node providing network controller (NC) functionality. A first node in the network, which is capable of generating SALTs, may assume NC functionality, and may distribute the SALT to at least one other node within the network. The first node may receive from the at least one other node, during admission to the network, a request for a dynamic encryption key, with the request being encrypted using a static encryption key unique to the at least one other node, and the static encryption key being determined based on the SALT. The first node may then send a response comprising one or more dynamic encryption keys to the at least one node, for use in network communications, wherein the response is encrypted using a static encryption key
