摘要： A computer implemented method for controlling a software defined network (SDN) is disclosed. The method includes providing one or more client portals configured for facilitating users controlling networked devices, generating configuration data based on input received from users via the client portals, and provising a master SDN controller for managing data flow control on the SDN network. The master SDN controller is operable to route data for the networked devices, generate a plurality of discrete co-controllers each associated with a particular end user with each co-controller having configuration data and routing data for an associated networked device, dispatching the co-controllers to the networked devices associated with the respective end users, installing the co-controllers on the networked devices, and registering the installed co-controllers with the master SDN controller for controlling the routing of data and configuration of the networked devices.

摘要： The present invention relates to methods and systems for minimizing alien crosstalk between connectors. Specifically, the methods and systems relate to isolation and compensation techniques for minimizing alien crosstalk between connectors for use with high-speed data cabling. A frame can be configured to receive a number of connectors. Shield structures may be positioned to isolate at least a subset of the connectors from one another. The connectors can be positioned to move at least a subset of the connectors away from alignment with a common plane. A signal compensator may be configured to adjust a data signal to compensate for alien crosstalk. The connectors are configured to efficiently and accurately propagate high-speed data signals by, among other functions, minimizing alien crosstalk.

摘要： Methods and systems for multiple carrier frequency, half duplex cable telemetry for a wellsite. The methods involve generating a first type of bi-directional message in a first propagation mode, generating a second type of bi-directional message in the first propagation mode and in a second propagation mode, transmitting over a cable operatively coupling a surface modem and a downhole modem the first and second types of bi-directional message sequentially in a plurality of time periods across a single frequency bandwidth, and separating each of the first and second types of bi-directional message from a most subsequently transmitted one of the first and second types of bi-directional message by a quiet time sample during which no message is transmitted.

摘要： A method for precoding an information symbol conveying data for transmission between a plurality of transmitters and a plurality of receivers via a plurality of communication channels over a subcarrier frequency, the number of transmitters (N) is different than the number of active receivers (K) for that subcarrier frequency, the method comprising: receiving by said transmitters information pertaining to supportabilities of said receivers to decode non-linearly precoded data; determining a precoding scheme defining for which of said receivers said data to be transmitted by said transmitters shall be precoded using at least one of linear precoding and non-linear precoding, according to said supportabilities; constructing a signal by applying a reversible mapping to said information symbol, said reversible mapping includes elements each respectively associated with a particular one of said receivers, such that those said receivers supporting the decoding of said non-linearly precoded data are capable of reversing said reversible mapping to said information symbol, while for those said receivers not supporting the decoding of said non-linearly precoded data said information symbol is unaffected by said reversible mapping; constructing a precoder characterized by N≠K such that said precoder is configured to perform regularized generalized inversion of a communication channel matrix.

摘要： Methods, systems, and devices for pre-distortion of multi-level signaling are described. A device may identify two multi-level signals that are to be transmitted over two transmission lines at the same time. The device may estimate the crosstalk expected to be caused by one of the multi-level signals on the other during propagation. Based on the expected crosstalk, the device may generate a signal that compensates for the expected crosstalk. In some examples, the signal may be a combination of the first signal and a cancelation signal. In some examples, once the compensated signal has been generated, it is transmitted over its respective transmission line at the same time that the other multi-level is transmitted over its respective transmission line.

摘要： The present disclosure is directed to systems, apparatuses, and methods for performing continuous or periodic link training. Existing link training protocols generally perform link training only once during startup or initialization of a link and, as a result, are limited in their applications. After link training is performed and Open Systems Interconnect (OSI) data link layer and other high-layer data is transmitted across the link, no further link training is performed using these existing link training protocols. However, parameters of the link may change over time after link training is performed, such as temperature of the link and voltage levels of signals transmitted over the link by the transmitter of the transmitter-receiver pair.
