Network TCP tunnels are dynamically configured to support intra-application connectivity of a distributed application. Tunnel origins listen on each server's loopback address. This listening configuration permits only applications running on the same server to connect. A tunnel gateway application interfaces with the distributed application on each server and includes a tunnel endpoint manager configured to select one or more TCP ports. These selected ports are each associated with a separate TCP listeners. Once associated, data from the instance of the distributed application resident on each of the plurality of servers in the server cluster is routed through these TCP connections and a UDP datagram-orientated communication channel formed between each peer in the server cluster. Each instance of the distributed application can thereafter access peers in the server cluster through each unique UDP datagram-orientated communication channel.

A method, apparatus, electronic device, and computer readable storage medium for communication between private networks are provided. An embodiment of the method may include: receiving a communication request sent by a first sub-instance provided in a first private network, the first sub-instance being created based on that the first private network initiates a network registration request to a master instance; determining a second private network as a destination based on the communication request; and sending the communication request to the second private network through a second sub-instance provided in the second private network, the second sub-instance being created based on that the second private network initiates a network registration request to the master instance, wherein the first private network, the second private network, and a cloud enterprise network provided with the master instance forms a star topology centered on the cloud enterprise network.

A network system is connected to a first physical network comprising: a first data transmission node that transmits data used for a first service and a second data transmission node that transmits data used for a second service and to a second physical network including at least one apparatus for receiving data from the first and the second data transmission nodes, and constructs a virtual network for each service between the first and the second physical networks.

A communication master device (101) manages a plurality of communication slave devices (102). An investigation unit (301) investigates status of retention of transmission waiting data in the plurality of communication slave devices (102). A period specification unit (302) specifies a length of a transmission permitted period in which transmission of the transmission waiting data is permitted and a length of a transmission prohibited period in which the transmission of the transmission waiting data is prohibited, based on the status of the retention of the transmission waiting data in the plurality of communication slave devices (102).

A method includes: (a) transmitting, by the control device, control data containing one of the plurality of second parameters to the relay device; (b) determining, by at least one of the control device or the relay device, whether the one of the plurality of second parameters matches one of the plurality of first parameters; and (c) transmitting, by the relay device, the control data received from the control device in (a), using one of the plurality of interfaces of the relay device for which the one of the plurality of second parameters is set if it is determined in the determining that the one of the plurality of first parameters matches the one of the plurality of second parameters.

A vehicle relay device includes a plurality of communication ports. Each of the plurality of communication ports communicate with a communication device as a node in accordance with an Ethernet standard. A connection permission node that is a node to be connected is predefined for each of the plurality of communication ports. The vehicle relay device does not communicate with an unregistered node that is a node not registered as the connection permission node.

An apparatus for controlling a vehicle and a method thereof are provided. The apparatus includes a connectivity control unit (CCU) to internetwork with a server through a wireless network to provide a connected car service and an integrated body unit (IBU) to perform low power communication with another vehicle to control the CCU.

Disclosed herein are a method for managing an access control list based on an automotive Ethernet and an apparatus for the same. The method includes analyzing a new access control rule that is input to a vehicle in which the automotive Ethernet is applied, searching for any one target unit to manage the new access control rule in consideration of at least one of a destination and an application target corresponding to the new access control rule, and storing the new access control rule by transmitting a storage request message corresponding to the new access control rule to the target unit.

A data distribution system in comprises software application nodes that utilize a publish-subscribe communication mechanism for distribution of data in real-time or near real-time within a personal area network (PAN), local area network (LAN), or wide-area network (WAN) configuration. The distributed system communication software application nodes reside in medical devices, such as monitoring devices and cardiac defibrillators, and associated patient information delivery systems and patient data management systems comprising medical software installed on servers and end-user computing devices, including mobile devices.

A communication apparatus includes a notification device that notifies information, a first LAN interface that connects to a network, a second LAN interface that connects to a network, transmits a DHCP discovery packet via a LAN cable when the LAN cable is connected to the first LAN interface, and determines whether to provide a notification and to notify information based on a determination to provide a notification based on a DHCP offer packet transmitted in response to the DHCP discovery packet and network information used to communicate via the second LAN interface.
