Wire-speed switching

Wire-speed switching refers to the ability to achieve data exchange without bottlenecks in accordance with the data transmission speed on the network communication line. Its realization is based on ASIC (Application specific Integrated Circuit, application specific integrated circuit) chip, and completes protocol analysis and data packet forwarding through dedicated hardware, rather than through software based on the CPU of the switch. The realization of wire-speed switching also relies on distributed processing technology, and the data streams of multiple ports of the switch can be processed at the same time. Therefore, the LAN switch can be regarded as a parallel processing device using CPU, RISC and ASIC.
