A method is described that comprises collecting communication data travelling among a plurality of computing nodes in a networked environment. The method includes using the communication data to create a plurality of connectivity records, wherein each connectivity record comprises a communication between a source computing node and a destination computing node of the plurality of computing nodes. The method includes associating the communication with an application context and protocol. The method includes processing the plurality of connectivity records to eliminate connectivity records that meet at least one criteria, wherein the plurality of connectivity records includes associated application contexts and protocols, wherein a first portion of the plurality of connectivity records comprises the eliminated connectivity records, wherein a second portion of the plurality of connectivity records comprises the remainder of the connectivity records. The method includes building a graph using the second portion of the connectivity records.

Technologies for performing switch-based collective operations in a fabric architecture include a network switch communicatively coupled to a plurality of computing nodes. The network switch is configured to identify sub-operations of a collective operation of a collective operation request received from one of the computing nodes and identify a plurality of operands for each of the sub-operations. The network switch is additionally configured to request a value for each of the operands from a corresponding target computing node at which the respective value is stored, determine a result of the collective operation as a function of the requested operand values, and transmit the result to the requesting computing node. Other embodiments are described herein.

Examples of a method and apparatus for cross-chain resource transmission are described. The cross-chain resource transmission includes sending from a first account of a first blockchain to another blockchain. One example of the method is executed by the first blockchain and includes: initiating, by the first account, a first transaction used for cross-chain resource transmission, to decrement a first resource balance of the first account by a first quantity and save first data obtained through a consensus into the first blockchain based on execution of the first transaction, where the first data includes an authenticable message; and sending the first data and first location information to the relay end, which is used to send the authenticable message to the second blockchain, where a second resource balance of the second account is incremented by a second quantity.

A data packet comprises a header and a payload. At least one digital signal processor is used to configure the payload to transport at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment. A service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. At least one digital signal processor is used to configure a single field in the header consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. At least one digital signal processor is used to form the data packet including the configured header and the configured payload. A transmitter transmits the data packet.

One embodiment is related to a method for implementing a reentrant Small Computer System Interface (SCSI) target, comprising: associating each configuration operation for the SCSI target with a namespace identifier; for each namespace identifier, applying a lock preventing simultaneous execution to configuration operations associated with the same namespace identifier; and permitting simultaneous execution in parallel of configuration operations associated with different namespace identifiers.

If the sequence of a traffic of a first communication link from a communication apparatus to another communication apparatus includes a traffic of a second communication link from that another communication apparatus to a communication apparatus, latency is reduced, thereby saving processing time. If, after data is transmitted from a communication apparatus to another communication apparatus by the upper layer, a data receive response signal is required from that another communication apparatus to the communication apparatus, a predetermined frame including transmission grant information for that another communication apparatus to transmit the receive response signal and data is generated in the communication apparatus. The communication apparatus transmits this generated frame to that another communication apparatus. That is, data and transmission grant information are transmitted from the communication apparatus to that another communication apparatus as a predetermined frame.

A method for network communications from a first device to a second device includes communicating data from the first device to the second device by spawning a first virtual machine for a first network connection that virtualizes network capabilities of the electronic device, and using the virtualized network capabilities of the first virtual machine, transmitting a plurality of packets for communication to a first network address and port combination associated with the second device. The method further includes repeatedly changing to a respective another network address and port combination by repeatedly spawning a respective another virtual machine for a respective another network connection that virtualizes network capabilities of the electronic device, and using the virtualized network capabilities of the spawned respective another virtual machine, transmitting a plurality of packets for communication to the respective another network address and port combination associated with the second device.

Systems and methods for reducing latency on long distance point-to-point links where the point-to-point link is a Peripheral Component Interconnect (PCI) express (PCIE) link that modifies a receiver to advertise infinite or unlimited credits. A transmitter sends packets to the receiver. If the receiver's buffers fill, the receiver, contrary to PCIE doctrine, drops the packet and returns a negative acknowledgement (NAK) packet to the transmitter. The transmitter, on receipt of the NAK packet, resends packets beginning with the one for which the NAK packet was sent. By the time these resent packets arrive, the receiver will have had time to manage the packets in the buffers and be ready to receive the resent packets.

An electronic device configured for electronic communications utilizing virtual dispersive networking includes: a network interface for communicating over a network; an application loaded onto the electronic device programmed to communicate over a network; and virtual dispersive networking software configured to create, for such application, a virtual machine comprising a virtual interface for the network interface of the electronic device; select a network protocol out of a plurality of available network protocols based on current communication requirements of the application; and cause network communications of the application to occur via the virtual network interface of the electronic device using the determined network protocol.

A medical device communication method that may be implemented within a variety of medical devices including but not limited to infusion pumps. The method may be implemented with a protocol stack for at least intra-device communication. Embodiments provide connection-oriented, connectionless-oriented, broadcast and multicast data exchange with priority handling of data, fragmentation, and reassembly of data, unique static and dynamic address assignment and hot swap capability for connected peripherals or subsystems.
