Abstract: Configuration of firewall functionality for routers operating within a multi-router network is contemplated. The firewall functionality configured for one or more of the routers may be based router positioning within the multi-router network. The firewall functionality may be automatically selected according to the router positioning in order to facilitate dynamic and/or adaptive router configuring.

Abstract: Assignment of directionality to interfaces, ports, receptacles, antennas and other input/output (I/O) employed by network devices to facilitate multi-device networking is contemplated. The directionality assignments may be used to facilitate assigning directionless and/or configurable router directionality in order to automatically, adaptively, dynamically or other otherwise facilitate inter-router connections within a multi-router network.

Abstract: Correction of errors within over-the-air signaling is contemplated. The error correction may include correcting over-the-air signaling used to facilitate transmitting content, broadcast television, etc. according to error correction data transmitted separately from the over-the-air signaling. A receiver may be configured to process the over-the-air signaling according to the error correction data so as to facilitate the contemplated error correction.

Abstract: A digital (fiber optic) link transports one or more RF digital signal blocks, that when converted into analog and (optionally) converted to a RF center frequency with an D-A converter, form RF analog signal blocks. The RF analog signal block occupies a specified frequency band and is preferably capable of being distributed over a downstream coaxial portion of a HFC network and/or being broadcast. The D-A conversion is performed in a fiber node at a remote location where the transmission medium converts from digital optical fiber preferably to coaxial cable. The multiple RF digital signal blocks may be broadcast to multiple nodes or unicast to a single node. The RF signal blocks allow for any type of band-limited RF signal to be transported. The optical digital traffic to compose a RF analog signal blocks using a D-A converter may be point-to-point Ethernet, or may utilize a software-defined networking controller such as the one described in the OpenFlow™ specification, and may use buffering as necessary.

Abstract translation: 数字（光纤）链路传输一个或多个RF数字信号块，当将其转换成模拟和（可选地）用D-A转换器转换成RF中心频率时，形成RF模拟信号块。 RF模拟信号块占用指定的频带，并且优选地能够分布在HFC网络的下游同轴部分和/或被广播。 在传输介质从数字光纤优选地转换到同轴电缆的远程位置的光纤节点中进行D-A转换。 多个RF数字信号块可以广播到多个节点或单播到单个节点。 RF信号块允许传送任何类型的带限RF信号。 使用DA转换器构成RF模拟信号块的光学数字业务可以是点对点以太网，或者可以利用诸如OpenFlow TM规范中所述的软件定义的网络控制器，并且可以根据需要使用缓冲 。
