The utility model discloses a high-voltage SVC (switched virtual circuit) communication system based on a UDP (user datagram protocol) protocol, which comprises an industrial control machine, an Ethernet exchanger and a DSP (digital signal processing) module in a SVC control board. The industrial...
In contrast, UDP is considered aconnectionlessprotocol because it doesn't require the establishment of a virtual circuit before any data transfer occurs. The communication protocol only sends the packets, which means it has much lower bandwidth overhead and latency. With UDP, packets might take dif...
