A medical device comprises a control system, processing modules, and a wire bundle connecting the control system to the processing modules, the wire bundle comprising control lines and data lines. Each processing module is coupled to a respective set of sensors arranged to interface with a biological tissue site, the sensors being configured to capture analog physiological signals generated from the biological tissue site. The control system is configured to generate a control signal on the control lines to initiate a data collection cycle by the processing modules. In response to the control signal, each processing module is configured to perform a respective data collection process which comprises (i) capturing and processing an analog physiological signal on each enabled sensor to generate a data sample for each analog physiological signal captured on each enabled sensor, and (ii) outputting data samples to the control system on the data lines.

A method for a hypervisor to implement flow-based local egress in a multisite datacenter is disclosed. The method comprises: determining whether a first data packet of a first data flow has been received. If the first data packet has been received, then the hypervisor determines a MAC address of a first local gateway in a first site of a multisite datacenter that communicated the first data packet, and stores the MAC address of the first local gateway and a 5-tuple for the first data flow. Upon determining that a response for the first data flow has been received, the hypervisor determines whether the response includes the MAC address of the first local gateway. If the response includes a MAC address of another local gateway, then the hypervisor replaces, in the response, the MAC address of another local gateway with the MAC address of the first local gateway.

Apparatuses, methods, and systems are disclosed for data packet routing in a remote unit. An apparatus includes a processor that receives a data packet to be transmitted and determines packet routing information for the data packet, the packet routing information comprising at least one of: network slice information, a continuity type, and a data network name for the data packet. The processor also determines whether the packet routing information matches a network connection and sends the data packet over a matching network connection, in response to determining that the packet routing information matches a network connection. In some embodiments, the apparatus includes a transceiver that communicates with a mobile communication network using at least one network connection of a first connection type associated with network slice information, a continuity type, and a DNN.

Some embodiments provide novel inline switches that distribute data messages from source compute nodes (SCNs) to different groups of destination service compute nodes (DSCNs). In some embodiments, the inline switches are deployed in the source compute nodes datapaths (e.g., egress datapath). The inline switches in some embodiments are service switches that (1) receive data messages from the SCNs, (2) identify service nodes in a service-node cluster for processing the data messages based on service policies that the switches implement, and (3) use tunnels to send the received data messages to their identified service nodes. Alternatively, or conjunctively, the inline service switches of some embodiments (1) identify service-nodes cluster for processing the data messages based on service policies that the switches implement, and (2) use tunnels to send the received data messages to the identified service-node clusters. The service-node clusters can perform the same service or can perform different services in some embodiments. This tunnel-based approach for distributing data messages to service nodes/clusters is advantageous for seamlessly implementing in a datacenter a cloud-based XaaS model (where XaaS stands for X as a service, and X stands for anything), in which any number of services are provided by service providers in the cloud.

A system for controlling power distribution within a vehicular communication network, including a power source equipment comprising a first port in communication with a network node module of a device, and a Power over Ethernet (POE) management module. The POE management module is configured to enable POE to the device via the first port, monitor a current draw of the device, determine whether the current draw of the device exceeds a threshold, and disable POE to the device, responsive to determining that the current draw exceeds the threshold.

A method of propagating data packets in a network of nodes is disclosed. This may be a blockchain network such as, for example, the Bitcoin network. The method includes: collecting a set of first data packets during a first time period, the set including at least one data packet received from one or more first nodes in the network; generating a first mapping that assigns the first data packets of the set for relay to one or more neighbouring nodes connected to the node; computing a decorrelation metric value for the first mapping; determining whether the decorrelation metric value for the first mapping satisfies a first condition; in response to determining that the decorrelation metric value for the first mapping does not satisfy the first condition: generating a second mapping that assigns the first data packets of the set for relay to one or more neighbouring nodes connected to the node, the second mapping defining assignments that are different from those of the first mapping; computing a decorrelation metric value for the second mapping; and in response to determining that the decorrelation metric value for the second mapping satisfies the first condition, transmitting the first data packets of the set to neighbouring nodes according to the second mapping.

The vehicle control module is configured to receive status data, from the vehicle device, relating to a performance status or operational status of the vehicle. The vehicle control module further includes a second communication interface that enables wireless communications with the remote server. The wireless communications include sending status data to the remote server. The remote server is configured to receive and interpret the status data to determine if the vehicle requires service, and send a response to the vehicle.
