    Abstract: Techniques for operating a networking switch in two broadcast networks are provided. In some embodiments, the switch may instantiate a first controller client and a second controller client in a control plane of the switch; register the first controller client with a first broadcast controller associated with a first broadcast network; and register the second controller client with a second broadcast controller associated with a second broadcast network. The switch may further receive a first multicast route through the first controller client; receive a second multicast route through the second controller client; and program at least one of the first multicast route and the second multicast route into a multicast routing information base.

    Abstract: Techniques for leveraging MLD capabilities at edge nodes of network fabrics to receive SNMAs from silent hosts, and creating unicast addresses from the SNMAs for the silent nodes that are used as secondary matches in a network overlay if primary unicast address lookups fail. The edge nodes described herein may act as snoopers of MLD reports in order to identify the SNMAs of the silent hosts. The edge nodes then forge unicast addresses for the silent hosts that match with the least three bytes of the SNMAs. The forged unicast addresses are presented as unicast MAC/IP mappings in the fabric overlay. In situations where a primary IP address lookup fails, the look-up device performs a secondary lookup for a mapped address that has the last three bytes of the IP address. If a mapping is found, the lookup is sent as a unicast message to the matching MAC address.

    Abstract: The techniques describe example network systems providing core-facing designated forwarder (DF) election to forward multicast traffic into an EVPN of a core network. For example, a first PE device of a plurality of PE devices participating in an EVPN comprises one or more processors operably coupled to a memory, wherein the one or more processors are configured to: determine that a first multicast traffic flow has started for the first PE device; in response, send a source-active (SA) route to indicate the first multicast traffic flow has started for the first PE device; receive, from a second PE device, a second SA route that indicates that a second multicast traffic flow has started for the second PE device; and perform an election of a core-facing DF from among the first PE device and second PE device, wherein the core-facing DF is configured to forward the multicast traffic into the EVPN.

    Abstract: A method of proprietary TDMA (Time-Division Multiple Access) data modulated signals nonlinear signal splitting (switching) system is disclosed. Said TDMA system operates over distribution CATV infrastructure and in ES (extended spectrum) that is usually allocated above in the frequency band comparing to one defined in the CATV DOCSIS standard. Said system is meant to increase data throughput capacity over existing CATV based systems targeting primarily ES (Extended Spectrum band) by means of TDMA approach. The purpose of the RF switches based tap box is to connect specific device to which TDMA packet is relayed to. This approach reduces excessive losses that are present in standard tap boxes by disconnecting other devices, which are not receiving or sending related TDMA data packets. The described method introduces switch control receiver concept that allows for configuration of various operation modes such as regular switched TDMA, amplified and broadcast modes.

    Abstract: Systems, methods, and apparatuses relating to a user defined formatting instruction to configure multicast Benes network circuitry are described. In one embodiment, a processor includes a decoder to decode a single instruction into a decoded single instruction, the single instruction having fields that identify packed input data, packed control data, and a packed data destination; and an execution unit to execute the decoded single instruction to: send the packed control data to respective control inputs of a circuit that comprises an inverse butterfly circuit coupled in series to a butterfly circuit, wherein the inverse butterfly circuit comprises a first plurality of stages of multicast switches and the butterfly circuit comprises a second plurality of stages of multicast switches, read, once from storage separate from the circuit, each element of the packed input data as respective inputs of the circuit, route the packed input data through the circuit according to the packed control data, and store resultant packed data from the circuit into the packed data destination.
