SpletAbstract: To support diverse use cases, 5G has changed the design and functionalities of its different protocol layers, like in Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) Layers. 5G RLC and PDCP layer supports Automatic Repeat Request (ARQ) and reordering mechanisms respectively, in Acknowledge Mode (AM). roof anchor point certificationSpletpdcp is a variant of the rcp(1) command. Unlike rcp(1), which copies files to a single remote host, pdcp can copy files to multiple remote hosts in parallel. However, pdcp does not recognize files in the format ''rname@rhost:path,'' therefore all source files must be on the local host machine.
