A management device selects an MEC device to be accessed by a plurality of client terminals forming a group from among MEC devices disposed in a plurality of places, and comprises an extracting means that extracts, from a database storing configuration information, the client terminals belonging to a specified group, network devices directly serving the client terminals, network devices between the serving network devices, and MEC devices to be treated as candidates for selection, and a selecting means that selects the MEC device to be accessed by the plurality of client terminals forming the group by using first and second amounts of latency, the first amount of latency being the amount of latency between each network device directly serving the client terminals belonging to the group and each MEC device, and the second amount of latency being the amount of latency between each network device directly serving the client terminals belonging to the group and each client terminal.

An in-vehicle communication system includes a plurality of in-vehicle devices each being connected to an Ethernet network and a CAN (Controller Area Network). Each of the plurality of in-vehicle devices transmits and receives information to and from another in-vehicle device via the Ethernet network and the CAN. At least one of the plurality of in-vehicle devices is able to transmit the same information to the Ethernet network and the CAN in parallel.

A traffic transfer system includes a switch (10) and a switch (20) and distributes and transfers traffic of communication on a network to a plurality of devices. The switch (10) determines a device of a transfer destination of input traffic among a plurality of devices by a hash function. The switch (10) transfers traffic to a first device when the first device determined to be a transfer destination is available and transfers traffic to the switch (20) when the first device is not available. The switch (20) determines a device to which the traffic transferred by the switch (10) is transferred, from available devices by a hash function. The switch (20) transfers the traffic to a second device determined to be a transfer destination.

A chassis front-end is disclosed. The chassis front-end may include a switchboard including an Ethernet switch, a Baseboard Management Controller, and a mid-plane connector. The chassis front-end may also include a mid-plane including at least one storage device connector and a speed logic to inform at least one storage device of an Ethernet speed of the chassis front-end. The Ethernet speeds may vary.

A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a global token based on a time duration specified for multiple meters that are in communication with the headend system through at least a mesh network in a normal condition. The global token is associated with the time duration and is applicable to the multiple meters. The headend system causes the global token to be broadcast via a broadcast network. After receiving the global token, the meter verifies the global token and determines the time duration associated with the global token. The meter further connects premises associated with the meter to a resource distribution network for at least the time duration associated with the global token.
