TCP LAYERS

4 Application (OSI - Layers5 through 7)           

HTTP, FTP, DNS

(Routing protocols like BGP and RIP, which for a variety of reasons run over TCP and UDP respectively, may also be considered part of the Internetwork layer)

3 Transport (OSI - Layers4 and 5)          

TCP, UDP, RTP, SCTP

(Routing protocols like OSPF, which run over IP, may also be considered part of the Internetwork layer)

2 Internetwork  (OSI - Layer 3)                

For TCP/IP this is the Internet Protocol (IP)

(Required protocols like ICMP and IGMP run over IP, but may still be considered part of the Internetwork layer; ARP does not run over IP)

1 Link             (OSI - Layers 1 and 2)        

Ethernet, Wi-Fi, MPLS, etc.
