A method and system is disclosed for traffic management in data networks. A first operation comprises allocating a first IP address to a first interface of a client device for data communications using a first sub-flow over a first path. Another operation comprises allocating a second IP address to a second interface of the client device for data communications using a second sub-flow over a second, different path, the second IP address being associated with the first IP address. Another operation comprises sending information relating to the allocated first and second IP addresses for the client device to an aggregating device for aggregating the first and second sub-flows, when received from the client device, for providing aggregated data to a destination device.

A method and system is described in which a client device comprises a memory arranged as a user space and a kernel space. One operation comprises providing in the user space a user space control module for receiving one or more application calls destined for the kernel space. Another operation comprises receiving by the user space control module an application call for requesting data transmission using one or more kernel space network services. Another operation comprises implementing the requested data transmission over multiple paths from the client device under the control of the user space control module.

Multi-path data communications

Network nodes, methods and computer program products are disclosed. The network node is for a wireless telecommunications network and comprises: processing logic operable to execute an application which establishes a data session for transmission of data packets between the network node and another network node; a first radio interface operable to support transmission of data packets with the another network node using a first radio access technology in accordance with any of a plurality of different data transport protocols; a second radio interface operable to support transmission of data packets with the another network node using a second radio access technology in accordance with any of a plurality of different data transport protocols; and a controller operable to select which radio interface and data transport protocol to use for transmission of the data packets of the data session between the network node and the another network node. In this way, the network node is able to transmit data packets between the network node and the other network node for the data session using any of the different radio interfaces and any of the different data transport protocols. This provides for the flexibility to select the radio interfaces and data transport protocols appropriate to the network conditions in order to improve the communication performance and alleviate any performance impacts caused by the network.

A user equipment, intermediate proxy node, method and computer program are disclosed. The user equipment comprises a network control domain and a user domain and is operable to receive and transmit data via multiple communication paths. The user equipment has conversion logic within the user domain operable to convert between a single data stream and multiple data streams formed from the single data stream, such that at least two of the multiple communication paths may be used for transmission of the multiple data streams formed from the single data stream.

Multiple path transmission of data

In one example embodiment, a first network element includes a memory storing computer-readable instructions and at least one processor configured to execute the computer-readable instructions to cause the first network element to, obtain user equipment (UE)-side parameter values from a user domain of the UE, convert a first data stream received from a second network element into multiple second data streams over multiple data communication paths between the UE and the first network element and allocate the multiple second data streams to at least one of the multiple data communication paths based on the UE-side parameter values.

Methods and network elements for multi-connectivity control

A client and a server communicate over multiple wireless access paths each using a different wireless network. A method performed at the server comprises receiving at the server a signal from the client via one of multiple wireless access paths, the signal comprising a transport layer portion including a transport layer identifier, the transport layer identifier providing an indication of a wireless access path, a network layer portion, and a data portion, determining from the transport layer identifier, a destination of at least a subset of the signals from the wireless access path indicated by the transport layer identifier, and routing the signal to the destination. If a flow is diverted to travel via a different route, then there must be some mechanism to ensure that the signal arrives at its intended destination. Preferably, a Multi-path Transport Control Protocol (MPTCP) is used as the transport layer protocol.

Multi-path wireless communication

A method is provided of receiving user data from multiple transmitters, the user data from each transmitter having been encoded as a Low Density Lattice codeword, and the multiple Low Density Lattice codewords having been transmitted so as to be received as a combined signal at a receiver, the method of receiving comprising the steps of: (i) receiving the signal, (ii) calculating coefficients of linear combinations of the codewords from the multiple transmitters, (iii) calculating a scaling factor to be applied to the signal based on the coefficients, (iv) applying the scaling factor to the signal to provide a linear combination of the codewords, (v) decoding the linear combination of the codewords based on channel state information to obtain an optimal independent linear combination of user data, (vi) repeating steps (ii), (iii) (iv) and (v) to obtain at least as many optimal independent linear combinations as the number of transmitters, and recovering the user data from the optimal independent linear combinations.

The congestion control capability may be configured to provide congestion control for a transport flow of a transport connection, sent from a transport flow sender to a transport flow receiver, based on flow control associated with the transport flow. The transport flow may traverse a flow queue of a link buffer of a link endpoint. The link endpoint may provide to the transport flow sender, via an off-band signaling channel, an indication of the saturation state of the flow queue of the transport flow. The transport flow sender may control transmission of packets of the transport flow based on the indication of the saturation state of the flow queue of the transport flow.
