Methods and systems for managing a Multipath Transmission Control Protocol (MPTCP) in an electronic device during data transport between the electronic device (client device) and other electronic device (host device) are described. The method includes monitoring one or more factors associated with the MPTCP implemented in the client device. Further, based on the one or more factors that are monitored, the method includes determining whether to enable the MPTCP in the electronic device for a current data transport. Thereafter, the method includes determining a mode, among a plurality of modes provided for the MPTCP, to control a plurality of subflows of the MPTCP when the MPTCP is enabled for the current data transport. The method further includes dynamically switching the mode of the MPTCP during the current data transport based on the one or more factors being monitored during the current data transport.

The present invention relates to a content-centric network on-demand distance vector route method, comprising: a request source node of a required request route broadcasts a route request packet CCN_RREQ to other nodes in a network, and starts a route discovery process; after a target node receives the route request packet CCN_RREQ, replying with a route reply packet CCN_RREP; after the request source node receives the route reply packet CCN_RREP returned by the target node, establishing a path between the request source node and the target node according to the content of the route reply packet CCN_RREP.

Embodiments provide an SDN, an SDN configuration method, an SDN-based data transmission method, and a network controller. A data packet combination function and a data packet split function are separately configured on nodes in the SDN. Therefore, when data packets of a first service are received, multiple small data packets of the first service may be combined into one large data packet. In comparison with transmission of the multiple small data packets, transmission efficiency of the SDN can be improved by transmitting the combined data packet.

Techniques and architectures may be used to generate data center network topologies that use less reliable and less expensive links mixed with links of higher reliability. Such topologies may be categorized into reliability classes, where each class corresponds to a bound(s) on reliability of paths that include the links. A topology class may be selected for use by an application based, at least in part, on the degree of reliability demanded by the application.

A first communication device determines one or more parameters related to a format of a media access control layer (MAC) data unit for an uplink (UL) multi-user (MU) transmission. The format of the MAC data unit for the UL MU transmission is different than a format of a MAC data unit for an UL single user (SU) transmission. The first communication device generates one or more data units that include the one or more parameters. The first communication device transmits the one or more data units to a plurality of second communication devices to inform the plurality of second communication devices of the format of the MAC data unit for UL MU transmissions by the plurality of second communication devices to the first communication device.

Creation of a virtual overlay for a multipath network with tiered topology is disclosed. A virtual-node module may group network nodes connected within a common tier, which is initially the tier furthest from the core. This module may also group network nodes at a consecutive tier, closer to the core, that connect a pairs of groupings in the common tier by links between the common and consecutive tiers. Groupings with a common network node may be combined and designated as virtual nodes. A virtual-link module may sum bandwidths for network links between virtual-node pairs with nodes in both the common and consecutive tiers. A check module may combine virtual nodes and links and network nodes and links not yet virtualized in a graph, which it may check for a cycle. An iteration module may iterate both tiers toward the core, triggering further grouping, summing, and updating until no loop exists.

Systems, methods, and computer-readable storage media for executing a copy service. A copy service engine can monitoring network data flow in a network, detect packet data containing a contract defining copy parameters for the execution of a copy service, and determine, based on the contract, when the particular data flow hits a particular network node specified in the contract parameters. When the data flow hits the specified node, the copy service engine can execute the copy service which copies the particular data flow, determines one or more endpoints for sending the copied data flow, and deploys the copies to the one or more endpoints.

A plurality of nodes are maintained in a switchless network, wherein each of the plurality of nodes has at least one host channel adapter for communication. A management datagram that indicates source to destination routes for communication in the plurality of nodes is provided. An attribute is configured in the management datagram to allow the management datagram to be propagated among the plurality of nodes of the switchless network without being terminated at host channel adapters.

A processor initiates an execution of a network driver in a first node comprising a master node of a plurality of nodes in a switchless network. The network driver configures the plurality of nodes and service level in the switchless network by transmitting management datagrams from the master node, wherein the management datagrams include an attribute that allows the management datagrams to be propagated among the plurality of nodes of the switchless network without being terminated at host channel adapters of the plurality of nodes.

In embodiments of distributed coordination of mesh network configuration updates, pending commissioning datasets are managed and distributed to coordinate configuration changes of parameters that control participation in, and secure communication over, a mesh network. Pending network commissioning datasets are managed across fragmentation of the mesh network into multiple partitions and subsequent merging of the fragments to ensure that the most recent updates to pending commissioning datasets are propagated to mesh network devices and that all mesh network devices will receive pending commissioning datasets before the time that the pending commissioning dataset becomes the active commissioning dataset for the mesh network.
