The SIP protocol is an Application Layer protocol designed to be independent of the underlying Transport Layer ; it can run on Transmission Control Protocol ( TCP ), User Datagram Protocol ( UDP ), or Stream Control Transmission Protocol ( SCTP ).

For such applications, protocols like the Real-time Transport Protocol ( RTP ) running over the User Datagram Protocol ( UDP ) are usually recommended instead.

When used with Transport Layer Security or Datagram Transport Layer Security requests are received on port 10161 and traps are sent to port 10162 ..

* Datagram Transport Layer Security ( DTLS ), is used in Cisco AnyConnect VPN, to solve the issues SSL / TLS has with tunneling over UDP.

However, it has also been implemented with datagram-oriented transport protocols, such as the User Datagram Protocol ( UDP ) and the Datagram Congestion Control Protocol ( DCCP ), usage which has been standardized independently using the term Datagram Transport Layer Security ( DTLS ).

This layer manages Real-Time Transport Protocols, User Datagram Packets ( UDP ) and Real-Time Transport Control Protocols ( RTCP ).

In information technology, the Datagram Transport Layer Security ( DTLS ) protocol provides communications privacy for datagram protocols.

Because it operates at the IP network layer, CBQ provides the same benefits across any Layer 2 technology and is equally effective with any IP protocol, such as Transmission Control Protocol ( TCP ) and User Datagram Protocol ( UDP ).

Although Diffie – Hellman key agreement itself is an anonymous ( non-authenticated ) key-agreement protocol, it provides the basis for a variety of authenticated protocols, and is used to provide perfect forward secrecy in Transport Layer Security's ephemeral modes ( referred to as EDH or DHE depending on the cipher suite ).

As SSL evolved into Transport Layer Security ( TLS ), the current version of HTTPS was formally specified by RFC 2818 in May 2000.

To transfer data reliably, applications must utilize an appropriate Transport Layer protocol, such as Transmission Control Protocol ( TCP ), which provides a reliable stream.

* StartTLS — use the LDAPv3 Transport Layer Security ( TLS ) extension for a secure connection

should be encrypted using Transport Layer Security ( TLS ).

The StartTLS operation establishes Transport Layer Security ( the descendant of SSL ) on the connection.

* RFC 2830-LDAPv3: Extension for Transport Layer Security

Encrypted communication for POP3 is either requested after protocol initiation, using the STLS command, if supported, or by POP3S, which connects to the server using Transport Layer Security ( TLS ) or Secure Sockets Layer ( SSL ) on well-known TCP port 995.

The STARTTLS extension allows the use of Transport Layer Security ( TLS ) or Secure Sockets Layer ( SSL ) to be negotiated using the STLS command, on the standard POP3 port, rather than an alternate.

It underpins such Internet standards as Transport Layer Security ( TLS ), PGP, and GPG.

* Secure Socket Layer, now codified as the IETF standard Transport Layer Security ( TLS )

The most widely used is the Transport Layer Security ( TLS, previously called SSL ) feature built into most current Internet browsers.

* RFC 4344, The Secure Shell ( SSH ) Transport Layer Encryption Modes

* RFC 4345, Improved Arcfour Modes for the Secure Shell ( SSH ) Transport Layer Protocol

* RFC 4419, Diffie-Hellman Group Exchange for the Secure Shell ( SSH ) Transport Layer Protocol ( March 2006 )

* RFC 5656, Elliptic Curve Algorithm Integration in the Secure Shell Transport Layer ( December 2009 )

The functionality of the transport layer alone is comparable to Transport Layer Security ( TLS ); the user authentication layer is highly extensible with custom authentication methods ; and the connection layer provides the ability to multiplex many secondary sessions into a single SSH connection, a feature comparable to BEEP and not available in TLS.

When the client program on the destination computer receives them, the TCP layer ( Transport Layer ) reassembles the individual segments and ensures they are correctly ordered and error free as it streams them to an application.

It is recommended to use HTTP Strict Transport Security with HTTPS to protect users from man-in-the-middle attacks.

According to Chékarou Bagoudou, Chief of the Division of Road Safety and Security of the Nigerien Ministry of Transport, there were 4338 officially reported road accidents in 2008, with 7443 victims, of which 616 were killed.

As has happened with other early Internet protocols, extensions to the Telnet protocol provide Transport Layer Security ( TLS ) security and Simple Authentication and Security Layer ( SASL ) authentication that address the above issues.

For example, Intel AMT ( a component of Intel vPro technology ), includes Transport Layer Security ( TLS ), an industry-standard protocol that strengthens encryption.

Some other Internet security systems in widespread use, such as Secure Sockets Layer ( SSL ), Transport Layer Security ( TLS ) and Secure Shell ( SSH ), operate in the upper layers of the TCP / IP model.
