The Specification Artist
Helps people see the world in a new
way.
6
The Standards Engineer
Codifies well-understood phenomena
and
applies them to well-known problems

Specification vs. Standard
v Starts with a blank canvas • Starts with defined goal
v Free format
v Usually evolves
v Often describes an implementation
v Says many (perhaps different) things to many people
v Sometimes “you had to be there”
v Inspires
• Format dictated by Standard
• Evolution by formal means
• Implementation Independent
• Unambiguous
• All you need to know is right there (or in the references)
• Communicates

802.15.1 SDL
uDerived a picture of what the structure of the BT spec is in IEEE terms.
uHelped to uncover holes in existing spec
uEnables bench testing and validating of components
uProvides a common language between the SIG and the IEEE
uGeneration of TTCN from SDL is possible
14
Implications for the future of Standards
uNormative SDL makes an unambiguous Standard
uWorking SDL models can be used to extend currently working Standards, minimizing the danger of breaking the protocol
uSDL makes the relationship between Standards and Test Suites explicit

Future Bluetooth/IEEE Collaboration
uIEEE 802.15 continues to work with the Bluetooth Special Interest Groupn Submission of Erratan “Early” updates of the Spec from the SIG – current
version of Draft includes v1.1 Bluetooth Specificationn Plans for future revisions ofw Version 1.xw Future versions
uThere now is an overlap of “ownership” of the two documents.

IEEE: An Overview
u Established in 1884 (AIEE & IRE)
u Membership was 360,00 Dec99;
66% USA & 33% Non-USA
u Produces 30 percent of the world's published literature in electrical
engineering, computers and control technology,
u Holds annually more than 300 major conferences
u Has more than 800 active standards with 700 under development.

IEEE P802 LAN/MAN
u IEEE Project 802 Local and Metropolitan Area Network Standards Committee
u Accredited by ANSI, Sponsored by IEEE Computer Societyn Ethernet, Token Ring, Wireless, Cable Modem Standardsn Bridging, VLAN, Security Standards
uMeets three times per year (400 individuals, 15% non-US)
u Develops equivalent IEC/ISO JTC 1 standardsJTC 1 series of equivalent standards are ISO 8802-nnn

22
IEEE 802 Standards Principals
uDue Process through established rules and procedures
uConsensus highly desired, near unanimity is generally the rule
uOpenness where all individuals, world-wide, have access to the process
uBalance maintained by having balloting group include both developers and users
uRight to Appeal both procedural and technical issues at any time during the process
