MTU & Bandwidth Calculator

Compute MTU overhead, fragmentation and transfer time at various bandwidths.

Settings (mtu=, bandwidth= Mbit/s, size=)

Output

MTU: 1500 bytes (default 1500)
IPv4 header: 20 bytes
IPv6 header: 40 bytes
TCP header: 20 bytes (1460 bytes TCP payload per packet)
UDP header: 8 bytes (1472 bytes UDP payload per packet)

Transfer estimate:
  Size: 1,000,000 bytes
  Bandwidth: 100 Mbit/s
  Wire time (best case): 0.080 s
