Routing packets by a router involves establishing a first flow configured for forwarding the packets from a first ingress interface to a first egress interface of the router; determining a condition to modify the first flow; deactivating the first flow; establishing a second flow configured for forwarding the packets from at least one of (1) the first ingress interface to a second egress interface, (2) a second ingress interface to the first egress interface, or (3) a second ingress interface to a second egress interface; and activating the second flow.

A method for data communication between a first node and a second node over a data paths coupling the first node and the second node includes transmitting messages between the first node and the second node over the data paths including transmitting at least some of the messages over a first data path using a first communication protocol, and transmitting at least some of the messages over a second data path using a second communication protocol and determining that the first data path is altering a flow of messages over the first data path due to the messages being transmitted using the first communication protocol, and in response to the determining, adjusting a number of messages sent over the data paths including decreasing a number of the messages transmitted over the first data path and increasing a number of messages transmitted over the second data path.

A device may receive an indication to establish a communication session between a first device and a second device for a file transfer. The device may receive, from the second device, metadata. The metadata may be used to identify files of a set of files. The device may identify the files for transfer from the second device to the first device based on the metadata. The device may cause multiple communication sessions to be established between the first device and the second device. The multiple connections may be used to transfer the files from the second device to the first device. The device may receive, from the second device, the files. The files may be received via the multiple communication sessions.

A communication device capable of communicating over a network on behalf of a consumer device, the network being configured such transport of packets through the network is provided by each communication device in the network listening for and relaying packets, the communication device comprising a relay unit configured to listen for packets and relay them over the network, a mode unit configured to identify whether the consumer device is active or non-active with respect to the network, and a timing unit configured to control the time that the relay unit listens for packets in dependence on that identification.

According to one embodiment, a communication device includes: a communicator, a first circuitry and a second circuitry. The communicator establishes a communication connection with a destination communication device over a communication network and to communicate a packet relating to first information using the communication connection. The first circuitry determines a transmission interval of a packet relating to second information that is different from the first information, based on characteristic information on the communication network. The second circuitry performs control to transmit the packet relating to the second information to the destination communication device using the communication connection in accordance with the transmission interval determined by the first circuitry during at least a time period when the communication connection is established and communication of the packet relating to the first information is not performed.

A method for data communication between a first node and a second node over a data path coupling the first node and the second node includes transmitting a segment of data from the first node to the second node over the data path as a number of messages, the number of messages being transmitted according to a transmission order. A degree of redundancy associated with each message of the number of messages is determined based on a position of said message in the transmission order.

An example method is provided for a host to perform load balancing for multiple network interface controllers (NICs) configured as a team. The method may comprise the host detecting egress packets from a virtualized computing instance supported by the host for transmission to a destination via the team. The method may also comprise the host selecting one of the multiple NICs from the team based on load balancing weights associated with the respective multiple NICs. Each load balancing weight may be assigned based on a network speed supported by the associated NIC, and different load balancing weights are indicative of different network speeds among the multiple NICs in the team. The method may further comprise the host sending, via the selected one of the multiple NICs, the egress packets to the destination.

When a proxy device is used between a transmission terminal and a reception terminal, receives final data from the transmission terminal, and fails immediately thereafter, a situation is avoided where transmission is completed in the transmission terminal, but reception is not completed in the reception terminal. There is provided a means for not returning ACK when a data packet is received in a state in which there is no data which waits for ACK and transmission of which is in progress, and there is no data which waits for arrangement and reception of which is in progress in the proxy device, for returning ACK for data received one step before when a data packet is received in a state in which there is data which waits for ACK and transmission of which is in progress, or there is data which waits for arrangement and reception of which is in progress.

A communication device comprising: a first processing function for performing protocol processing of received datagrams; a second processing function for performing protocol processing for received datagrams at a higher level than the first processing function; and a power controller; the device being configured such that the power controller can place the second processing function in a low power state while the first processing function remains capable of performing protocol processing of received datagrams; and the first processing function comprising a mesh datagram processing function configured to process datagrams of a mesh protocol by analyzing received datagrams of the mesh protocol, determining a subset of those datagrams for retransmission, and causing the device to retransmit the determined ones of those datagrams.
