Virtual switches like VPPand OVS-DPDK, have benefited from the vector packet processing technology inDPDK to scale process millions of packets per second, while TCP and UDP socketbased. 因为这些 sockets 对设置了 Router Alert option 的 ip 包感兴趣. The Raw Socket client initiates a TCP connection with the Raw Socket server and sends the packetized data across the IP network to the Raw Socket server, which retrieves the serial data from the packets and sends it to the serial interface, and on to the utility management system. For example, you can write the same code for parsing packets that are captured using DPDK, libpcap, WinPcap, raw sockets or read from a PCAP/PCAPNG file.
