An Ethernet header compression method and apparatus and an Ethernet header decompression method and apparatus. After receiving an Ethernet frame including a first to-be-compressed field, a compression end compresses an Ethernet header of the Ethernet frame based on a first correspondence including first compression information and a value of the first to-be-compressed field and the first compression information. Correspondingly, a decompression end decompresses an Ethernet header of a compressed Ethernet frame based on the first correspondence when receiving the compressed Ethernet frame. In the embodiments of this application, because the Ethernet header of the Ethernet frame is compressed, communication resources is saved.

The invention relates to a system for development interface and a data transmission method for development interface. The system includes a development board and a host computer. The development board is electrically connected to the host computer by a debug interface. The data format transmitted by host computer includes a header field, an address field and a data field. When performing mass data transfer, a specific command is set in the header field to lift the restriction for the length of the data field. When the development board receives the specific command, a serial data transmission mode is switched to receive all data of the data field.

Described are embodiments for Ethernet header compression. A base station sends, to a wireless device, a radio resource control message including a packet data convergence protocol (PDCP) configuration parameter indicating Ethernet header compression for a data radio bearer. Based on the PDCP configuration parameter, the base station sends, to the wireless device, a message including: a source medium access control (MAC) address and a destination MAC address, and a header compression index corresponding to the source MAC address and the destination MAC address. The base station sends, to the wireless device, a compressed Ethernet packet: including a packet header being compressed based on the message; and including the corresponding header compression index.

A multi-node communication network may include a plurality of nodes including a first node and a second node. Each of the plurality of nodes may include a communication interface and a controller. The first node may be configured to: obtain an uncompressed packet, the uncompressed packet having uncompressed header data and a payload; compress the uncompressed header data into compressed header data having a tag and at least one compressed unit (CU), the tag indicating at least one type of compression for the at least one CU; and transmit a packet having the compressed header data and the payload to the second node. The second node may be configured to: receive the packet having the compressed header data and the payload; and based at least on the tag, decompress the at least one CU.

Disclosed are methods, systems, apparatus, and computer programs for compressing an Ethernet packet. In one aspect, a method involves mapping a portion of the Ethernet packet to a connection identity to compress the Ethernet packet. Additionally, the method involves encoding, in a user plane protocol stack layer, the connection identity in a data structure for transmission.

Embodiments of the disclosure provide systems and methods for providing random access to segmented and encrypted or compressed data stored in a repository. Retrieving at least a portion of a file stored in a repository can comprise storing a plurality of files in the repository. A request to retrieve at least a portion of one of the plurality of files can be received and object metadata for the requested one of the plurality of files can be obtained. A determination can be made based on the obtained metadata as to whether the requested one of the plurality of files is a multipart file. In response to determining the requested one of the plurality of files is not a multipart file, a single file retrieval process performing and in response to determining the requested one or the plurality of files is a multipart file, a multipart retrieval process can be performed.

Disclosed are methods, systems, apparatus, and computer programs for adaptation layer enhancements in new radio (NR) integrated access and backhaul (IAB) networks. In one aspect, a method includes performing, by an adaptation layer of an IAB node of the IAB network, header compression on one or more headers of a packet for transmission in the IAB network; and transmitting the packet with the one or more compressed headers to a destination IAB node of the IAB network.
