A communication system and method are disclosed for transmitting packets of information in at least one first format over a communications link that utilizes packets of information in a second format. In certain embodiments, the packets of information in a first format are converted to packets of information in the second format prior to transmission via the communications link by packing and fragmenting the information in the first format in a coordinated manner. Embodiments may also utilize packing subheaders and fragmentation control bits in the packing and fragmentation processes.

Disclosed is an operating method of a terminal, comprising the steps of: receiving, from a base station, a radio resource control (RRC) message including information for indicating whether to use uplink data compression (UDC); receiving data from an upper application layer of the terminal; compressing the data and encoding the compressed data; generating an uplink data compression (UDC) header and a service data adaption protocol (SDAP) header together; generating a block to which the UDC header and the SDAP header are bonded in the encoded data; and transmitting the block to a lower layer of the terminal.

The present disclosure provides a method, apparatus and computer program product for determining a data transfer manner. The method comprises determining a first transfer completion time for transferring a data block from a first device to a second device without compression; determining a second transfer completion time for transferring the data block from the first device to the second device with the compression performed; and selecting, based on a comparison of the first and second transfer completion time, a transfer manner for the data block from a first transfer manner comprising compressing the data block and transferring the compressed data block and a second transfer manner of directly transferring the data block without compression. Through the embodiments, compressing and uncompressing are evaluated based on the transfer completion time before data transfer, so as to select a transfer manner suitable for data to be transferred and for devices that perform data transfer.

The communication circuity is capable of switching network traffic of multiple link layer protocols. Additionally, the network switch includes one or more memory devices storing instructions that, when executed, cause the network switch to receive, with the communication circuitry through an optical connection, network traffic to be forwarded, and determine a link layer protocol of the received network traffic. The instructions additionally cause the network switch to forward the network traffic as a function of the determined link layer protocol. Other embodiments are also described and claimed.
