Various aspects include methods for Transmission Control Protocol (TCP)/Internet Protocol (IP) (TCP/IP) packet transmission and compression of headers for TCP/IP packet transmission. Various embodiments may include a packet data convergence protocol (PDCP) layer of a processing device applying least significant bit (LSB) encoding to a TCP Timestamp (TS) option of a TCP/IP packet using an offset parameter of zero to generate a compressed header in response to determining that a TCP TS field of the TCP/IP packet and a TCP TS field of a last TCP/IP packet transmitted have a same value. In some embodiments, a Timestamp Value (TSVal) field or a Timestamp Echo Reply (TSEcho) field of the TCP TS option of the compressed header may have a size of one byte.

Methods, apparatuses, and systems are provided for improving utilization of the satellite communications system through various “deltacasting” techniques for handling content sets (e.g., feeds or websites). Embodiments operate in a client-server context, including a server optimizer, a client optimizer, and, in some embodiments, a pre-positioning client. Within this client-server context, content sets are multicast (e.g., anticipatorily pre-positioned in a local dictionary) to end users of the communications system and are handled at the content set level, according to set-level metadata and/or user preferences. In some embodiments, when locally stored information from the content sets is requested by a user, deltacasting techniques are used to generate fingerprints for use in identifying and exploit multicasting and/or other opportunities for increased utilization of links of the communications system.

The present invention provide a method for processing data packet and apparatus and the method includes: receiving or sending compression configuration information of an application layer packet; and performing compression processing or decompression processing on the application layer packet according to the compression configuration information. By using the foregoing method, compression and decompression processing of the application layer packet can be implemented, thereby reducing overheads of packet transmission and improving utilization of a network resource.

Some underlying networks such as Low-Power Wide-Area Networks (LPWAN) have limited communication bandwidth and strict requirements on maximum message size. It is recognized herein that these requirements may pose a challenge for data or resource exchange between two service layer (SL) entities, for example, because resource representations to be exchanged may have too large a size to be supported by the underlying networks. In some cases, traditional data compression algorithms can be used to alleviate this problem to some degree, but it is recognized herein that there are associated computation costs due to compression and decompression that may not be affordable for constrained IoT devices. Various embodiments described herein address this problem, among others, by defining a Resource Representation Common Part (RRCP) and storing it at the service layer. In some cases, the RRCP is not transmitted between SL entities, thereby reducing SL message sizes to cater to the constraints of underlying networks

Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for compression and decompression of information centric network (ICN) names and/or ICN common fields at Packet Data Convergence Protocol (PDCP) layer. For example, an electronic device can include processor circuitry and radio front end circuitry coupled to the processor circuitry. The processor circuitry can be configured to receive a first information centric network (ICN) packet including an ICN name or an ICN common field and compress the ICN name or the ICN common field at a Packet Data Convergence Protocol (PDCP) layer. The processor circuitry can be further configured to provide the compressed ICN name or the compressed ICN common field to a lower protocol layer. The radio front end circuitry can be configured to transmit a second ICN packet including the compressed ICN name or the compressed ICN common field.

A technique for compressing and transmitting data without hampering real-time performance can be offered. In a data compression transmission system for collecting data generated by a plurality of devices at a central server via a network, an intermediate server is arranged between the devices and the central server. Each of the devices includes a packet cache processing unit for converting the generated data to a hash value based on a cache. The intermediate server includes a packet cache processing unit for decoding the hash value to original data based on the cache, a buffering unit for aggregating the data and outputting the data as a long packet, and a compression encoding unit for compressing the data and generating encoded data.
