This disclosure describes methods, devices, and systems related to coordinating channel switch times and specifying device operation (for example, transmitting device operation) to ensure data reception by one or more devices (for example, receiving devices). A device may receive a data path setup request frame from a second device. The device may cause to send a data path setup response frame. The device may cause to establish a communication with the second device on a first channel. The device may cause to establish a communication with the second device on a second channel at a first time. The device may cause to wait, by the device, at least for a duration specified by a channel switch time (CST) parameter. The device may cause to send device data to the second device over the first channel or the second channel based at least in part on the CST parameter.

The present subject matter relates to methods, systems, devices, circuitry and equipment providing for communication service to be transported between first and second networks, and which monitors the communication service and/or injects test signals, and which can provide redundancy. At least one demarcation point or line is established between the first network and the second network, and/or between the first network, the second network and/or a third network. The Circuitry comprises a plurality of input amplifiers, output amplifiers, and multiplexer switches between a plurality of Port connectors. An SFP module or a WSFP module is inserted in the Ports.

Described herein are systems, methods, and software to enhance the implementation of communication rules in a computing network. In one example, a method of operating a communication settings system maintains communication rules for a plurality of networks, wherein the communication rules define forwarding actions for ingress and egress packets to and from applications in the plurality of computing networks. The service further identifies a configuration request from a computing network with applications executing in the computing network, identifies a subset of the communication rules based on the plurality of applications, and provides the subset of the communication rules to the computing network.

An apparatus is disclosed. The apparatus comprises a plurality of antennas and an integrated circuit chip coupled to the plurality of antennas, and is configured to process cellular signals received from the plurality of antennas in accordance with a cellular communication protocol and to process radio frequency identification (RFID) signals received from the plurality of antennas in accordance with an RFID protocol.

Some embodiments provide a method for configuring a gateway machine in a datacenter. The method receives a definition of a logical network for implementation in the datacenter. The logical network includes at least one logical switch to which logical network endpoints attach and a logical router for handling data traffic between the logical network endpoints in the datacenter and an external network. The method receives configuration data attaching a third-party service to at least one interface of the logical router via an additional logical switch designated for service attachments. The third-party service is for performing non-forwarding processing on the data traffic between the logical network endpoints and the external network. The method configures the gateway machine in the datacenter to implement the logical router and redirect at least a subset of the data traffic between the logical network endpoints and the external network to the attached third-party service.

A first ingress interface on a switch receives a first control packet for establishing a Transmission Control Protocol (TCP) session and selects a first engine running on a first line card in the switch. A second ingress interface receives a second control packet and selects the same first engine. Data associated with the TCP session received by the first or second ingress interface subsequent to establishing the TCP session is to be forwarded to the first engine. The first ingress interface receives a third control packet and sends, to the selected first engine, a notification indicating the TCP session which is to be tracked. The first or second ingress interface receives a fourth packet with a payload associated with the TCP session and forwards, to the selected first engine, a copy of the fourth packet, thereby facilitating a plurality of engine instances to support application identification.

A network topology may be determined based on flow data exported from a network. A topology generator analyzes flow data and determines a topology based on devices and connections between the devices indicated in the flow data. The topology generator may also infer types of the devices based on communication protocols and port numbers used by the devices. The topology generator may continually update the topology as additional flow data is exported from devices in the network and analyzed. As a result, the topology reflects a current status of devices in the network based on the communications indicated in the additional flow data. The topology generator may also retrieve flow data from a specified time period or flow data related to a specified device to generate topologies that are targeted for analysis or troubleshooting of a particular network issue.

A data center includes: a server including a control plane; a data plane that is configured to receive network connection information from the control plane; and a storage group including a plurality of first storage devices. The data plane may be configured to set connections between the server and the plurality of first storage devices based on the network connection information corresponding to each first storage device of the plurality of first storage devices.

A method, system, and/or computer program product configures hierarchical cloud resources. A supervisor server receives a signal indicating a boundary of a set of hierarchical cloud resources. The boundary describes a level of resource sharing among the set of hierarchical cloud resources, which includes a set of software applications, a set of middleware that supports one or more software applications from the set of software applications, and a set of virtual mechanisms that supports one or more middleware from the set of middleware. The supervisor server receives a signal from one or more Isolation/Density (I/D) switches, which are associated with one or more software applications from the set of software applications and one or more middleware from the set of the middleware, and then configures the hierarchical cloud resources, according to the boundary of the set of hierarchical cloud resources, and according to settings of the I/D switches.
