The protocols that are often used in each layers in each OSI reference model are:
Layers Protocols
Layer 7- Application SMTP, HTTP, FTP, POP3, SNMP
Layer 6- Presentation MPEG, ASCH, SSL, TLS
Layer 5-Session NetBIOS, SAP
Layer 4-Transport TCP, UDP
Layer 3-Network IPV5, IPV6, ICMP, IPSEC, ARP, MPLS.
Layer 2-Data Link RAPA, PPP, Frame Relay, ATM, Fiber Cable.
Layer 1-Physical RS232, 100BaseTX, ISDN, 11.
<h3>What is OSI Model?</h3>
The OSI Model is known to be a kind of a logical and conceptual framework that tells all about network communication that is often used by systems in an open to interconnection and also in any communication with other forms of systems.
Note that the Open System Interconnection (OSI Model) is one that tells more about a logical network and it is one that also tells about computer packet transfer via the use of various layers of protocols.
Therefore, The protocols that are often used in each layers in each OSI reference model are:
Layers Protocols
Layer 7- Application SMTP, HTTP, FTP, POP3, SNMP
Layer 6- Presentation MPEG, ASCH, SSL, TLS
Layer 5-Session NetBIOS, SAP
Layer 4-Transport TCP, UDP
Layer 3-Network IPV5, IPV6, ICMP, IPSEC, ARP, MPLS.
Layer 2-Data Link RAPA, PPP, Frame Relay, ATM, Fiber Cable.
