A method and a device for reconfiguring a first interconnection of a first node with a second node of a backhaul subnetwork in a local area network including a plurality of nodes, the first and second nodes being interconnected by a radio connection in a first frequency band. A controller node: selects a third node of the local area network, the third node being different from the first and second nodes, establishes a second interconnection between the first and third nodes by a radio connection in a second frequency band different from the first frequency band, deletes the first interconnection when the second interconnection is established.

An apparatus and method for efficiently performing power management for multiple clients of a semiconductor chip that supports remote manageability. In various implementations, a network interface receives a packet, and sends at least an indication of the packet to a manageability processing circuitry (MPC) of a processing node with multiple clients for processing tasks. The MPC determines whether a client or itself is a destination needed to process the packet. If the destination is the MPC, then packet processing is done by the MPC without involvement from the clients, which can be in an idle state. For example, the MPC can process a remote manageability packet requesting diagnostic information from one or more clients of the processing node. The network interface and the MPC use a sideband communication channel for data transmission, which foregoes lane training for further reduction in latency and power consumption.

Communication network architectures, systems and methods for supporting a network of mobile nodes. As a non-limiting example, various aspects of this disclosure provide communication network architectures, systems, and methods for supporting a dynamically configurable communication network comprising a complex array of both static and moving communication nodes (e.g., the Internet of moving things).

Technologies for hairpinning network traffic include a compute device with a network interface controller (NIC) configured to receive, by a virtual Ethernet port aggregator (VEPA) agent of a media access control (MAC) of the NIC, a network packet from a virtual machine (VM). The VEPA agent is configured to transmit the received network packet to an agent deployed on an accelerator device of the NIC and the agent is configured to forward the received network packet to a virtual Ethernet bridge (VEB) hairpin agent of the accelerator device. The VEB hairpin agent is configured to determine whether a target destination of the network packet corresponds to another VM, return the received network packet to the agent deployed the accelerator device. The agent is further configured to forward the received network packet to the VEPA agent, which is further configured to transmit the received network packet to the other VM.

Various implementations disclosed herein include systems, methods and apparatuses that determine connections between non-external facing ports. In some implementations, a method includes identifying one or more port pair connections between non-external network facing ports associated with respective pairs of compliant devices based on associated uplink metadata, wherein the respective pairs of compliant devices are included in a plurality of compliant devices within a network; determining the respective status of each compliant device associated with a particular one of the one or more port pair connections; and adding link data for a particular one of the one or more port pair connections to topology-link map data based at least on the determined respective status of each compliant device associated with the particular one of the one or more port pair connections, wherein the topology-link map data archives accessible information about the topology of the network based at least on the uplink metadata.

An Ethernet Metropolitan Area Network provides connectivity to one or more customer premises to packet-bases services, such as ATM, Frame Relay, or IP while advantageously providing a mechanism for assuring security and regulation of customer traffic. Upon receipt of each customer-generated information frame, an ingress Multi-Service Platform (MSP) tags the frame with a customer descriptor that specifically identifies the recipient customer. In practice, the MSP tags each frame by overwriting the Virtual Local Area Network (VLAN) identifier with the routing descriptor. Using the customer descriptor in each frame, a recipient Provider Edge Router (PER) or ATM switch can map the information as appropriate to direct the information to the specific customer. In addition, the customer descriptor may also include Quality of Service (QoS) allowing the recipient Provider Edge Router (PER) or ATM switch to vary the QoS level accordingly.

A bridging apparatus includes an address-table managing unit configured to manage an address table in which devices connected to networks are registered, a presence-check-frame transmission control unit configured to transmit a presence check frame for checking whether a device is connected to a network, and a network transmission-reception control unit configured to call, upon receipt of a response request frame transmitted from a first device connected to a first network toward a second device connected to a second network, the address-table managing unit to register the first device in the address table and check whether the second device is registered in the address table, and when the second device is registered, transmit an acknowledgement to the first device and transfer the response request frame to the second network, whereas when the second device is not registered, instruct the presence-check-frame transmission control unit to transfer the response request frame to the second network.

Various implementations disclosed herein include apparatuses, systems, and methods for providing virtual/virtualized network functions. In some implementations, a method includes determining that a first virtual router is configured to operate as a backup router for a second virtual router. The first virtual router and the second virtual router may reside within a public cloud. The method also includes determining, by the first virtual router, whether the second virtual router is able to route packets. The method further includes updating, by the first virtual router, a routing table to indicate that the first virtual router should be used to route packets when the second virtual router is unable to route packets.
