✅ MTU

Maximum Transmission Unit
패킷 또는 프레임 기반 네트워크에서 전송될 수 있는 최대 크기 패킷, 프레임
한 번에 전송할 수 있는 최대 전송량 byte

  • MTU would depend on environment
  • Ethernet environment: MTU 1500
  • FDDI environment: MTU 4000
  • X.25 environment: MTU 576
  • Gigabit environment: MTU 9000

✅ MSS

Maximum Segment Size On TCP, maximum size of data that can be transmitted

  • MSS: MTU - IP header - TCP header

  • Ethernet environment: MTU 1500 - IP header 20 - TCP header 20
  • thus, MSS for Ethernet is 1460
