Cut-Through Switching is a data packet forwarding method in network devices where the switch begins forwarding a frame as soon as the destination address is read, without waiting for the entire frame to be received. In systems architecture, particularly for low-latency crypto trading infrastructures, this technique minimizes processing delay, significantly reducing the time for market data or order messages to travel through the network.
Mechanism
Unlike store-and-forward switching, which buffers the entire frame to check for errors before transmission, cut-through switching processes the frame header to determine the outgoing port and immediately commences forwarding. This reduces latency by overlapping the reception and transmission processes, though it carries the risk of forwarding corrupted frames if errors are present later in the packet.
Methodology
Implementing cut-through switching is a key architectural decision for ultra-low-latency environments, such as those supporting high-frequency crypto trading or real-time RFQ systems where microseconds influence execution advantage. While increasing throughput and decreasing latency, system architects must consider its trade-off against error detection capabilities, balancing speed requirements with network reliability for critical financial operations.
