  1. ATM STANDARDS • GROUP 17 • DIAN NURFITRI M.NASIR AHMAD WET020028 • NURALIZA CHE HASSAN WET020127 • NURHUZAIMA MAHZAN WET020130 • NURZALINA MOHD ZAWAWI WET020139 • MUZAMIEL HADY A.MUNIR WET030160

  2. Introduction • Standard - a set of rules or procedures that are either widely used or officially specified. • 3 main standard bodies : • International Telecommunications Union-Telecommunications (formerly the CCITT) • American National Standards Institute • European Telecommunications Standards Institute

  3. 4 industry forums currently participating : • The ATM Forum • The Frame Relay Forum • The Internet Engineering Task Force (IETF) • The Switched Multimegabit Data Service Interest Group (SIG)

  4. International Telecommunication Union (ITU) • An international organization established to standardize and regulate international radio and telecommunication. • Responsible for studying technical, operating, and tariff questions and issuing recommendations on them, with the goal of standardizing telecommunications worldwide. • Combines the standards-setting activities of the predecessor organizations formerly called the International Telegraph and Telephone Consultative Committee (CCITT) and the International Radio Consultative Committee (CCIR).

  5. Examples of ITU-T B-ISDN Standards: • 1.113 Vocabulary for B-ISDN • 1.121 Broadband Aspects of ISDN • 1.150 B-ISDN Asynchronous Transfer Mode Functional Characteristics • 1.211 General Service Aspects of B-ISDN • 1.311 B-ISDN General Network Aspects • 1.321 B-ISDN Protocol Reference Model and Its Application

  6. American National Standards Institute (ANSI) • The premier formal B-ISDN/ATM standards organization in the United States. • Adopts and adds detail to the ITU-T standards and deals with issues concerning the unique North American transmission requirements. • Structured into several committees, which cover a broad spectrum of areas: • TlEl-covering the physical interface aspects of ATM • TIMI-covering the maintenance aspects of ATM • TlAl-covering performance aspects • T1S1.5-covering the network, service, signaling, ATM layer, interfaces, and AAL aspects of ATM.

  7. Examples of ANSI Standards: • T1.624-1993, BISDN UNI: Rates and Formats Specification • T1.627-1993, BISDN ATM Functionality and Specification • T1.629-1993, BISDN ATM Adaptation Layer 3/4 Common Part Functionality and Specification • T1.633, Frame Relay Bearer Service Interworking

  8. European Telecommunications Standards Institute (ETSI) • The ETSI deals with issues concerning the European communications. • Generate, on the basis of global standards, more detailed specifications adapted to the unique historical, technical, and regulatory situation of each region.

  9. ATM Forum The ATM Forum was formed in October, 1991 by four companies: Northern Telecom, Sprint, SUN Microsystems, and Digital Equipment Corporation (DEC). In January 1992, the membership was opened to the industry. There are 3 categories of membership: Principal - Participate in technical and marketing committee meetings. Auditing - Receive copies of the technical and marketing committee documents. User - Participate in End User Roundtable (ENR) meetings.

  10. There are three types of committees in the ATM Forum: Technical Produces implementation specifications and is organized into a number of technical "subject matter expert" sub committees. Market Awareness and Education (MA&E) Produces tutorials, presentations, press releases, newsletters, and other informative material. End User Roundtable (ENR) user group Goal- to collect higher level requirements and provide these to the technical and MA&E committees.

  11. Frame Relay forum Many aspects of frame relay are similar to those of ATM. They are both connection-oriented protocols, involve ISDN-based signaling, and require similar network management functions. The ATM Forum and the Frame Relay Forum corroborated closely in the production of Frame Relay/ATM internetworking specifications.

  12. Today, the Frame Relay Forum and the ATM Forum are placing a considerable amount of emphasis on the interoperability of frame relay and ATM services. There are implementation agreements for communicating frame relay traffic across an ATM network, and for communicating between frame relay end systems and ATM end systems. This is not limited to basic data transfer but is expanding to include all types of data and ultimately video traffic. The Frame Relay Forum is currently completing a packetised voice implementation agreement which will go on to be an ATM Forum standard later this year. Frame relay will be used well into the next century because it provides a needed service now and provides a `natural' data service on future ATM networks.

  13. Internet Engineering Task Force(IETF) • Non-profit organization • An open community of network designer, operator.. • Defining the standard of Internet such TCP/IP • Organized by topic into several ares (routing, transport, security…) • Supervise by Internet Architechture Board (IAB) • Support by Internet Society (ISOC) including logistical, financial and insurance • Standard are expressed in form of Request for Comment (RFC)

  14. SMDS Interest Group (SIG) • BackGround • switched multimegabit data services • high-speed, packet-switched, datagram-based WAN networking technology • speed up to 1.544Mbps over Digital Signal Level 1 (DS-1) • speed up to 44.736Mbps over Digital Signal Level 3 (DS-3) • Network Component • CPE (customer premise equipment), carrier equipment and SNI (subscriber network interface) • CPE owned and maintain by customer

  15. end devices such as terminal, personal computer, routers and modem • carrier equipment consist of high speed WAN swiches • has it own specification of network equipment –Bellcore • SNI is the interface between CPE and carrier equipment • border between CPE and carrier equipment

  16. Diagram above show how SNI Provides an Interface Between the CPE and the Carrier Equipment in SMDS

  17. SMDS Interface Protocol • a.k.a SIP • use by CPE and carrier equipment to communicate • provide connection through SNI to allow CPE to access SMDS network • based on the IEEE 802.6 Distributed Queue Dual Bus (DQDB) • DQDB was chosen as the basis because it is an open standard that supports all the SMDS service. • plus, it was designed for compatibility with current carrier transmission standards

  18. CREATING STANDARDS - THE PROCESS

  19. SUMMARY

  20. CREATING STANDARDS • Players • Vendors • Users • Network Service Providers • Process • Work plan • Meetings and contributions • Drafting and review • Voting and approval • Acceptance and interoperability
