    • A scalable networking protocol that allows multiple nodes to communicate via a multi-channel network medium is described. The networking protocol allows any node on the network to assign itself as the active network server. The active network server polls client nodes based on a lineup card. The lineup card includes a high priority queue for low-latency devices, and a low priority queue for devices that can tolerate higher latencies. Network information is sent on the channels as fragments. The protocol provides bad-channel detection and retransmission of fragments in a fragment-by-fragment basis. Support for streaming data or asynchronous data is provided by allocating time slots on the network and allowing two intelligent nodes to talk directly to each other during count-limited token sessions, as arbitrated by the active network server. The network node serving as the active network server can be changed on a dynamic basis, and is typically determined by the first node initiating a transmit request on a sleeping network. Client nodes are addressed by dynamic-polling using an address isolation scheme.
    • 描述了允许多个节点经由多信道网络介质进行通信的可扩展网络协议。 网络协议允许网络上的任何节点将其自身分配为活动网络服务器。 主动网络服务器根据阵容卡轮询客户端节点。 阵容卡包括用于低延迟设备的高优先级队列,以及能够容忍更高延迟的设备的低优先级队列。 网络信息作为片段在信道上发送。 该协议以片段为基础提供了坏信道检测和片段重传。 通过在网络上分配时隙来提供对流数据或异步数据的支持,并允许两个智能节点在计数有限的令牌会话期间彼此直接通话,如由主动网络服务器仲裁的。 用作活动网络服务器的网络节点可以在动态基础上改变,并且通常由第一节点在休眠网络上发起发送请求来确定。 使用地址隔离方案通过动态轮询寻址客户端节点。

    • A modular feed-though adapter that allows an electrical connection to a power line network adapter without “using up” an electrical outlet is described. In one embodiment, the modular feed-through adapter also provides noise filtering to protect electrical equipment plugged into the feed-through outlet. The noise filtering also protects the power line network data signals from noise generated by the devices plugged into the feed-through adapter. In one embodiment, the network connections provided by the feed-through adapter are low voltage connections, thus allowing the network connections from the feed-through adapter to be safely plugged directly into low-voltage equipment such as computer network cards and the like. In one embodiment, the modular adapter includes a balun to couple network data signals to the power line.

    • A universal gateway that allows data to be transferred between one or more network protocols and one or more control protocols is described. The various protocols can coexist on the same physical network medium or on separate networks. The gateway also provides tunneling of network protocols through a selected protocol, and centralized control of network nodes. By using the gateway, end-users can mesh together traditionally standalone, incompatible, networks into a universally accessible, centrally administered, “super-network.” The gateway provides a centralized node database, support for legacy protocols, a rules engine, and an object-oriented class library interface. Configuration is simplified through automatic device discovery. The centralized node database is managed by an active server node. High reliability access to the centralized node database is enhanced by the system fault tolerance provided by standby server nodes. When used in connection with a power line network, the gateway provides the ability to distribute various types of data streams over the power line. Routing handlers provided by the gateway allow virtually any of the legacy data networking services such as TCP/IP to be routed over the power-line.
    • 描述允许数据在一个或多个网络协议和一个或多个控制协议之间传送的通用网关。 各种协议可以在相同的物理网络介质上或在单独的网络上共存。 网关还通过选定的协议提供网络协议的隧道,并对网络节点进行集中控制。 通过使用网关,最终用户可以将传统的独立,不兼容的网络联网到一个普遍可访问的,集中管理的“超级网络”中。 网关提供集中式节点数据库,支持旧协议,规则引擎和面向对象的类库接口。 通过自动设备发现简化配置。 集中式节点数据库由活动服务器节点管理。 通过备用服务器节点提供的系统容错能力,可以高度可靠地访问集中式节点数据库。 当与电力线网络结合使用时,网关提供通过电力线分配各种类型的数据流的能力。 由网关提供的路由处理程序几乎可以使任何传统数据网络服务(如TCP / IP)通过电源线路由。
