Transport Area Working Group

Transport Area Working Group
Name	Transport Area Working Group
Abbreviation	TSVWG
Formation	2002
Parent organization	Internet Engineering Task Force
Website	[https://datatracker.ietf.org/wg/tsvwg/ tsvwg]

Transport Area Working Group is a working group within the Internet Engineering Task Force (IETF) that focuses on the development of Internet Protocol (IP) transport protocols, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), as well as Stream Control Transmission Protocol (SCTP) and Datagram Congestion Control Protocol (DCCP). The group's work is closely related to other IETF working groups, including the Internet Architecture Board (IAB) and the Internet Research Task Force (IRTF), and is influenced by the work of organizations such as the International Telecommunication Union (ITU) and the World Wide Web Consortium (W3C). The Transport Area Working Group collaborates with other standards organizations, including the Institute of Electrical and Electronics Engineers (IEEE) and the European Telecommunications Standards Institute (ETSI), to ensure interoperability and consistency across different networks and devices, such as those using Wi-Fi and Long-Term Evolution (LTE) technologies.

History and formation

The Transport Area Working Group was formed in 2002, as a result of the reorganization of the IETF's transport-related working groups, including the Transport Layer Working Group and the Datagram Congestion Control Protocol Working Group. The group's formation was influenced by the work of Vint Cerf and Bob Kahn, who are often referred to as the "fathers of the Internet", and were involved in the development of the ARPANET project, which was funded by the United States Department of Defense (DoD) and managed by the Defense Advanced Research Projects Agency (DARPA). The Transport Area Working Group's early work was focused on the development of TCP and UDP, as well as the Real-time Transport Protocol (RTP) and the Real-time Transport Control Protocol (RTCP), which are used in applications such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV), and are supported by organizations such as the Society of Motion Picture and Television Engineers (SMPTE) and the Digital Video Broadcasting (DVB) project.

Scope and objectives

The Transport Area Working Group's scope includes the development of transport protocols and mechanisms for the Internet, with a focus on congestion control, quality of service (QoS), and multipath transmission. The group's objectives are to develop protocols and standards that provide reliable, efficient, and scalable transport services for a wide range of applications, including web browsing, file transfer, and real-time communication, and to collaborate with other IETF working groups, such as the Multipath TCP Working Group and the Congestion Exposure Working Group, to ensure consistency and interoperability across different networks and devices, such as those using IPv6 and Software-Defined Networking (SDN) technologies. The group's work is influenced by the Internet of Things (IoT) and the Tactile Internet, and is supported by organizations such as the Open Networking Foundation (ONF) and the Linux Foundation.

Key protocols and standards

The Transport Area Working Group has developed several key protocols and standards, including TCP, UDP, SCTP, and DCCP, as well as the Multipath TCP (MPTCP) and the Low Extra Delay Background Transport (LEDBAT) protocols. The group has also worked on the development of QoS mechanisms, such as DiffServ and IntServ, and has collaborated with other IETF working groups, such as the Audio/Video Transport Working Group and the Real-time Communication Working Group, to develop protocols and standards for real-time communication, such as WebRTC and SIP, which are used in applications such as Skype and Google Hangouts. The group's work is influenced by the 3rd Generation Partnership Project (3GPP) and the 5th Generation Non-Standalone (5G NSA) architecture, and is supported by organizations such as the GSMA and the WiMAX Forum.

Organizational structure

The Transport Area Working Group is organized under the Transport Area of the IETF, which is responsible for the development of transport protocols and mechanisms for the Internet. The group is led by a chair, who is appointed by the IETF Chair, and is supported by a team of editors and contributors, who are responsible for the development and maintenance of the group's protocols and standards. The group's work is influenced by the IETF Trust and the Internet Society (ISOC), and is supported by organizations such as the Cisco Systems and the Juniper Networks.

Major activities and milestones

The Transport Area Working Group has been involved in several major activities and milestones, including the development of TCP and UDP, the deployment of IPv6, and the development of MPTCP and LEDBAT. The group has also collaborated with other IETF working groups, such as the IPv6 Working Group and the DNS Working Group, to develop protocols and standards for IPv6 and DNS, which are used in applications such as Cloud computing and Big data analytics. The group's work is influenced by the National Institute of Standards and Technology (NIST) and the European Union's Horizon 2020 program, and is supported by organizations such as the Amazon Web Services (AWS) and the Microsoft Azure.

Relationship with other IETF groups

The Transport Area Working Group has a close relationship with other IETF working groups, including the Internet Architecture Board (IAB) and the Internet Research Task Force (IRTF). The group collaborates with these organizations to ensure consistency and interoperability across different networks and devices, and to develop protocols and standards that meet the needs of a wide range of applications and use cases, such as Smart cities and Industrial Internet of Things (IIoT). The group's work is influenced by the IEEE 802.11 standard and the 3GPP 5G standard, and is supported by organizations such as the Ericsson and the Nokia. The Transport Area Working Group also collaborates with other standards organizations, including the ITU-T and the W3C, to ensure consistency and interoperability across different networks and devices, and to develop protocols and standards that meet the needs of a wide range of applications and use cases, such as Artificial intelligence (AI) and Machine learning (ML).
