Description:	7-layer model describing the theory of Network-Protocols

Details

The OSI model, also known as the ISO/OSI model, is a 7-layer model describing hundreds of Network-Protocols.
It is similar to the TCP-IP 4-layer model but splits the upper (application) layer and adds the lowest (physical) layer.

The ISO/IEC 7498 standard consists of 4 parts explaining networking theory, a vocabulary and the layer model.

• ISO/IEC-7498-1 (nonpub) - The Basic Model - ITU-T Recommendation X200
• ISO/IEC-7498-2 (nonpub) - Security Architecture
• ISO/IEC-7498-3 (nonpub) - Naming and addressing
• ISO/IEC-7498-4 (nonpub) - Management framework

Like most ISO / IEC standards the latest version of the documents are not free but have to get purchased.

FRITZ!OS

The following overview will only collect protocols which are relevant to FRITZ!OS and its modification:

TCP-IP: Application layer

• OSI-7: Application layer
  • DNS, DHCP, NTP, SNTP
  • FTP, FTPS, HTTP, HTTPS
  • SSH, SFTP, Telnet, TFTP
  • SMTP, SMTPS, POP3, POP3S
  • IMAP, IMAPS, NNTP, IRC
  • LDAP, SNMP, SOAP, SSDP
  • SIP, SMB, NFS
• OSI-6: Presentation layer
  • ASCII, MIME
  • SSL, TLS, PGP
• OSI-5: Session layer
  • Named-Pipes, Network-Sockets (connected)
  • NetBIOS, RPC, PPTP, RTP, SOCKS

TCP-IP: Transport layer

• OSI-4: Transport layer
  • TCP, UDP

TCP-IP: Internet layer

• OSI-3: Network layer
  • IP, IPv4, IPv6
  • ICMP, ICMPv6
  • IGMP, IPsec

TCP-IP: Link layer

• OSI-2: Data link layer
  • MAC, LLC
  • ARP, RARP, NDP, IND
  • ARQ, ATM
  • L2TP, PPP
• OSI-1: Physical layer
  • RS-232, Modem, ISDN
  • DSL, Fiber, Cable
  • Ethernet, WLAN
  • USB, Bluetooth
  • I2C, SPI

The TCP-IP suite / layer model does not care about the physical layer, as long as it can transfer Octets (Bytes).
