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.

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 ).

* RFC 4253, The Secure Shell ( SSH ) Transport Layer Protocol

* 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 4432, RSA Key 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.

To give another example, the validity of a pass on London Regional Transport services is until the end of the " transport day " -- that is to say, until 4: 30 am on the day after the " expiry " date stamped on the pass.

More than 4, 000 public-sector employees from the Ministry of Communications, Public Works, and Transport were fired in 1990.

On October 4, 1952, nine cartoonists left on a USO-Camp Shows tour of U. S. Armed Forces installations in Europe, traveling via a Military Air Transport Service plane from Westover Air Force Base in Massachusetts and landing at Rhein-Main Air Base in Germany.

Following the elections in late March 2006, Mofaz was moved from the position of Defense Minister and received the Transport ministry in the new Cabinet installed on 4 May 2006.

# The Layer 4 ( Transport Layer ) PDU is the segment for TCP, or the datagram for UDP

Layer 4 switching provides additional routing above layer 3 by using the port numbers found in the Transport layer header to make routing decisions.

The correct term for a data unit at the Data Link Layer — Layer 2 of the seven-layer OSI model — is a frame, and at Layer 4, the Transport Layer, the correct term is a segment or datagram.

* Transport and communication ( 4. 82 %)

Transport officials say 46. 8 percent of car accidents take place in cities, 21. 5 percent outside, 19. 5 percent on rural routes, 4. 2 percent on urban highways and 4. 2 percent on suburban highways.

In 1984 GEC became one of the first 100 companies to enter the FTSE 100 Index, at which time it was ranked third behind British Petroleum and Shell Transport and Trading with a market capitalisation of £ 4. 915 billion.

In 1978, the Ministry of Transport and Communications fined Venevisión 4, 000 bolívares on two different occasions in one week for violating the regulations for color broadcasting.

On 17 May 1966 he was found dead in his home Gwen's Transport Cafe in Leamington Spa where he lived with his wife and four daughters, one of his daughters, Carmen aged 4, was taken to hospital in Birmingham with two shot wounds.

* Veolia Transport Česká republika a. s. ( since 2006 a daughter of German company VEOLIA Transport Central Europe GmbH ) has 4 operator subcompanies:

** Veolia Transport Brabant, operating in middle and western Noord-Brabant with 4 urban networks in Breda, Tilburg, Bergen op Zoom and Roosendaal,

Transport for London estimated that £ 51m was owed by at least ten foreign embassies at that date (£ 50 million in unpaid congestion charge fines and £ 491, 000 in parking fines ), with the USA owing the most at £ 5 million and Russia second at £ 4. 4 million.

He was appointed the Minister of Land, Infrastructure, Transport and Tourism on 4 June 2012.

They are weighted this way: Housing: 41. 4 %, Food and Beverage: 17. 4 %, Transport: 17. 0 %, Medical Care: 6. 9 %, Other: 6. 9 %, Apparel: 6. 0 %, Entertainment: 4. 4 %.

On 4 December 2008 it was announced that Transport for London and the Department for Transport had signed the Crossrail Sponsors ' Agreement.

The Intermodal System for Global Transport ( SIT Global ), involving Nicaraguan and Canadian and American investors, proposes a combined railway, oil pipeline, and fibre optic cable ; a competing group, the Inter-Ocean Canal of Nicaragua, proposes building a railway linking two ports on either coast.

Transport for London constructed a cable car over the River Thames for Summer of 2012 just before the 2012 Summer Olympics began.

Transport for London have completed a cable car route nearby called the Emirates Air Line.

The ZVV ( German abbreviation for Zürcher Verkehrsverbund, translated into English as Zurich Transport Network or Zurich Traffic Network ) is a public transportation network system, combining rail, bus, tram, trolleybus, lake boat and cable car services in the canton of Zürich as well as Rapperswil-Jona and Pfäffikon SZ.
