Methods and systems may include processes that may implement abbreviated header communications. In some implementations, a method may include generating a packet including an abbreviated header, where the abbreviated header may include a pointer corresponding to values for multiple parameters associated with a physical layer of communication rather than the values for the multiple parameters. The method may also include transmitting the packet to a client device according to the values for the multiple parameters.

A method of sending blocks of data from a client to be stored at a storage server, wherein for each block compression and encryption is performed at the client, and deduplication is performed at the server. Security is thus enhanced as the block is compressed and encrypted when it is sent over an unsecured network and when it is stored in potentially a third-party backup system. Provisions are made to enable addition of new compression algorithms and for retirement of old compression algorithms, while ensuring that a client would not receive a block which was compressed using an unsupported, e.g., retired, compression algorithm. In some examples a compression algorithm ID is tied to an encryption key version to enable refresh of blocks compressed with old algorithm

Provided are a data transmission method and device. The method includes: processing a first data packet to be sent by using a compression strategy obtained in advance from a receiving end, deleting specified duplicated data comprised in the compression strategy in the first data packet; generating a second data packet to be sent from the processed first data packet, where the second data packet includes a modification record field for indicating the deleted duplicated data; and sending the second data packet to the receiving end.

In one embodiment, an apparatus comprises a network interface and a processor. The processor is to: receive, via the network interface, a plurality of data streams to be routed over a network, wherein the plurality of data streams correspond to sensor data captured by a plurality of sensors; identify, from the plurality of data streams, a set of related data streams that are contextually related; identify a convergence function to be performed on the set of related data streams, wherein the convergence function is for transforming the set of related data streams into a converged data stream that is smaller in size than the set of related data streams; perform the convergence function to transform the set of related data streams into the converged data stream; and route, via the network interface, the converged data stream to one or more corresponding destinations over the network.

The present invention relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes the steps of: configuring one Packet Data Convergence Protocol (PDCP) entity, at least one first RLC entity related to the one PDCP entity and at least one second RLC entity related to the one PDCP entity; determining whether a service data unit (SDU) to be transmitted is a special SDU or not; if the SDU is the special SDU, transmitting the SDU to the at least one first RLC entity; and if the SDU is not the special SDU, transmitting the SDU to the at least one second RLC entity.

A method of operating a first base station unit to process In-Phase and Quadrature (IQ) data for transmission to a second base station unit, the first and second base station units both being part of a disaggregated base station in a cellular telecommunications network and a method of operating a second base station unit to process a first and second data package processed by a first base station, the method including combining the first and second data packages.

A method for rebuilding data in a distributed storage network (DSN) including a plurality of storage units. A rebuilding module of the DSN selects an address range associated with memory of a storage unit of the DSN, and initiates execution of data rebuilding activities for the selected address range. The rebuilding module determines a first rebuilding rate of the storage unit for a timeframe subsequent to initiating the execution of the data rebuilding activities. The rebuilding module further operates to pause the execution of the data rebuilding activities for a pause timeframe, and determine a second rebuilding rate of the storage unit for the pause timeframe. In response to determining that the second rebuilding rate compares favorably to the first rebuilding rate, the rebuilding module resumes execution of the data rebuilding activities. If the comparison is unfavorable, a second address range is selected for data rebuilding activities.
