PCAP or PCAPNG file writer of 5G NR MAC packets
ThenrPCAPWriter
object creates a packet capture (PCAP) or packet capture next generation (PCAPNG) file writer object to write generated and recovered 5G new radio (NR) medium access control (MAC) packets to a PCAP or PCAPNG file (.pcap
or.pcapng
, respectively). To write 5G NR MAC packets, no native link type is available for NR. The object writes the 5G NR MAC packets to the PCAP or PCAPNG file by encapsulating the packets into a pseudo protocol with a link type. The object prepends each MAC packet with socket address link layer (SLL), internet protocol (IP), and user datagram protocol (UDP) headers followed by per-packet information. The encapsulation of packets enables the object to write a MAC packet with a maximum size of 65,482 bytes at a time. If the size of the MAC packet is greater than 65,482 bytes, the object truncates the remaining bytes.
creates a default 5G NR PCAP or PCAPNG file writer object.nrPCAPW
