About Lesson

Standards Organizations

Explain the role of standards organizations in establishing protocols for network interoperability.

Open Standards

Open standards encourage:

  • interoperability
  • competition
  • innovation

Standards organizations are:

  • vendor-neutral
  • non-profit organizations
  • established to develop and promote the concept of open standards.

Internet Standards

  • Internet Society (ISOC) – Promotes the open development and evolution of internet
  • Internet Architecture Board (IAB) – Responsible for management and development of internet standards
  • Internet Engineering Task Force (IETF) – Develops, updates, and maintains internet and TCP/IP technologies
  • Internet Research Task Force (IRTF) – Focused on long-term research related to internet and TCP/IP protocols

Standards organizations involved with the development and support of TCP/IP

  • Internet Corporation for Assigned Names and Numbers (ICANN) – Coordinates IP address allocation, the management of domain names, and assignment of other information
  • Internet Assigned Numbers Authority (IANA) – Oversees and manages IP address allocation, domain name management, and protocol identifiers for ICANN

Electronic and Communications Standards

  • Institute of Electrical and Electronics Engineers (IEEE, pronounced “I-triple-E”) – dedicated to creating standards in power and energy, healthcare, telecommunications, and networking
  • Electronic Industries Alliance (EIA) – develops standards relating to electrical wiring, connectors, and the 19-inch racks used to mount networking equipment
  • Telecommunications Industry Association (TIA) – develops communication standards in radio equipment, cellular towers, Voice over IP (VoIP) devices, satellite communications, and more
  • International Telecommunications Union-Telecommunication Standardization Sector (ITU-T) – defines standards for video compression, Internet Protocol Television (IPTV), and broadband communications, such as a digital subscriber line (DSL)
