About This Calculator:

TCP Window Size: The receive window size in bytes (typical: 64KB-16MB)
Latency: Round-trip time (RTT) in milliseconds
Frame Size: Maximum transmission unit (MTU), typically 1500 bytes
Overhead: Includes Ethernet preamble (8B), inter-frame gap (12B), headers (38B), IP (40B), and TCP (24B)
