A method for network communications from a first device to a second device includes communicating data from the first device to the second device by spawning a first virtual machine for a first network connection that virtualizes network capabilities of the electronic device, and using the virtualized network capabilities of the first virtual machine, transmitting a plurality of packets for communication to a first network address and port combination associated with the second device. The method further includes repeatedly changing to a respective another network address and port combination by repeatedly spawning a respective another virtual machine for a respective another network connection that virtualizes network capabilities of the electronic device, and using the virtualized network capabilities of the spawned respective another virtual machine, transmitting a plurality of packets for communication to the respective another network address and port combination associated with the second device.

In one exemplary aspect, an edge-gateway multipath method includes the step of providing an edge device in a local network communicatively coupled with a cloud-computing service in a cloud-computing network. A set of wide area network (WAN) links connected to the edge device are automatically detected. The WAN links are automatically measured without the need for an external router. The edge device is communicatively coupled with a central configuration point in the cloud-computing network. The method further includes the step of downloading, from the central configuration point, an enterprise-specific configuration data into the edge device. The enterprise-specific configuration data includes the gateway information. The edge device is communicatively coupled with a gateway in the cloud-computing network. The communicatively coupling of the edge device with the gateway includes a multipath (MP) protocol.

Embodiments of the present disclosure relate to a method of controlling physical data rate for optimizing throughput of multicast transport channels in at least one multicast channel, wherein the allocation of the at least one multicast transport channel to the at least one multicast channel is controlled such that inter alia at least one of all multicast transport channels to be allocated currently is placed within one multicast channel during the common sub-frame allocation period according to a pre-defined ruling when all multicast transport channels to be allocated currently do not fit into the one multicast channel, wherein a remainder of all multicast transport channels to be allocated currently is buffered and scheduled to be transmitted in a following common sub-frame allocation period. Further, a system for controlling physical data rate for optimizing throughput of multicast transport channels is described.

A routing system for distributing multicast routing information for a multicast service includes a plurality of routers including a multicast source router and a plurality of multicast receiver routers, the plurality of routers providing a multicast service, wherein the routers are configured to exchange multicast information associated with the multicast service including identification of multicast sources and the multicast receivers.

A first cell device obtains, from a second cell device, multicast information associated with the second cell device, where a first wireless coverage area associated with the first cell device at least partially overlaps a second wireless coverage area associated with the second cell device. The first cell device transmits the multicast information to an element management system, and receives, from the element management system, an instruction, generated based at least on the multicast information, to not use one or more subframes, associated with a multicast transmission session associated with the second cell device, to transmit during the multicast transmission session. The first cell device determines, after receiving the instruction, that the multicast transmission session has been initiated, and causes the first cell device to not use the one or more subframes to transmit during the multicast transmission session associated with the second cell device.

Information may be dynamically disseminated to network devices. In some embodiments, a data structure may be populated with first-type values and second-type values, a first delay time may be assigned to a first value of the first-type values based on the first value being associated with a first priority and a second delay time may be assigned to a second value of the first-type values based on the second value being associated with a second priority, and data structure information may be obtained from the data structure. The data structure information may be delivered such that the delivery of the data structure information to a first network device associated with the first value reflects the first delay time and the delivery of the data structure information to a second network device associated with the second value reflects the second delay time.

This application provides a data transmission method and communications devices. In some implementations, a first device instructs a second device to stop sending data of an application to the first device, receives from the second device first indication information indicating a sequence number of data that is of the application and that has been received by the second device from the first device, and sends to the second device second indication information indicating a sequence number of data that is of the application and that has been received by the first device from the second device. After a connection between the terminal device and a second server is established, the first and second indication information are used to transmit the data of the application through the connection.

A switch and a Frame Capture Managing Module (FCMM) for managing Ethernet frames. The FCMM receives a request for capturing Ethernet frames at a network interface of the switch. The request comprises an identity of the network interface and information relating to a second filter indicating Ethernet frames for monitoring by the network node. The FCMM sends to the switch, a configuration comprising the identity of the network interface of the switch, an indication about a first multicast channel, and information relating to a first filter. The FCMM sends a response comprising a second multicast channel relating to the first multicast channel. Furthermore, the switch receives a request for receiving Ethernet frame sent to the first multicast channel. The switch filters, by use of the first filter, received Ethernet frames into a collection of Ethernet frames. The switch sends the collection of Ethernet frames on the first multicast channel.

A router is configured for deployment in a first domain of a network. The router includes a processor and a transmitter. The processor is configured to access addresses of egress routers for a multicast flow that are partitioned into local addresses of egress routers in the first domain and external addresses of egress routers in a second domain of the network. The processor is also configured to prepend an explicit multicast route (EMR) to a packet in the multicast flow to form a first EMR packet. The EMR includes information representing the external addresses. The transmitter is configured to unicast the first EMR packet to an advertising border router (ABR) that conveys the multicast flow from the first domain to the second domain. In some cases, the router includes a receiver configured to receive another EMR packet from another router in another domain via a tunnel between the routers.

A content distribution network includes a first server in communication with an anycast server that provides content via a unicast signal, and with a multicast server that provides the content via a multicast signal. The first server is configured to receive a list of source addresses associated with the content, and to provide a metadata file including an anycast Internet protocol address of the anycast server from the list of source addresses as an Internet protocol address of the content in response to a first request for the content. When the number of client devices requesting the content exceeds a first threshold, the first server receives an updated list of sources including a multicast Internet protocol address of a multicast server, and provides the multicast Internet protocol address of the multicast server as the Internet protocol address of the content in the metadata file.
