Network Policies, Procedures and Standards Flashcards
The Internet Society
Aims to oversee the standardization of protocols to promote interoperability.
Coordinates Internet
-Design
-Engineering
-Management
The Internet Society - IAB
Internet Architecture Board (IAB)
Defines architecture of the internet
The Internet Society - IETF
Internet Engineering Task Force (IETF)
-Receives Architecture definitions from IAB
-Protocol engineering development
The Internet Society - IESG
Internet Engineering steering Group (IESG)
-Technical management of the IEFT
-Defines the Internet Standard
What is the The Internet Society?
Initiates working groups who investigates the actual details of the proposed standard or protocol.
-Draft version is developed
-Made available for consultation
-The IESG gives final approval
-Published as a Request for Comments (RFC)
-If the draft hasn’t progressed to RFC within 6 months it is withdrawn
The criteria
-Be stable and clear
-Be technically competent
-Have multiple, independent and interoperable implementations with substantial operational experience
-Gain significant public support
-Be useful within the internet domain.
Progression
To gain Standard status there must be at least TWO independent and interoperable implementations.
-If the implementations have been rigorously tested
-Internet standard is assigned along with
-STD number
-RFC number
ISO
International Standards Organisation (ISO)
Promote standardisation and related activities to facilitate international exchange of goods and services.
ISO collaborates with other organisations
International Electronic Commission (IEC)
Focused at the electrical and electronic engineering standards with the focus on hardware.
ISO and IEC collaborate through the Joint Technical Committee (JTC1) for IT standards
6 Step Development Process - Proposal Stage
New proposal assigned to technical can and working group
6 Step Development Process - Preparatory Stage
Working group prepares the draft
Once satisfied, its passed to the committee for consensus-building phase.
6 Step Development Process -Committee Stage
Registered at ISO central Secretariat
Distributed for balloting and comment
Once censuses is achieved it becomes a Draft International Standard (DIS)
6 Step Development Process -Enquiry Stage
DIS is circulated to all ISO member bodies
Time limit of 5 months for comment and vote on approval
It becomes a Final Draft International Standard
If not approved its returned to the working group
6 Step Development Process -Approval Stage
Redistributed for final acceptance
2 months time limit
Technical comments are no longer considered at this stage
If not agreed it is returned to the working group
6 Step Development Process -Final Stage
Once agreed its an International Standard.
Some minor editorial changes are allowed prior to the publications of the standard.
Telecommunications Standardization Sector (ITU)
Its is a United Nations specialized agency.
Members are governments.
Charter:
“is responsible for studying technical, operating and tariff questions and issuing recommendations on them with a view to standardization telecommunications on a worldwide basis”
Groupings
Network and Service Operations
Tariff and Accounting Principles
Telecommunications and Management
Network and Network Maintenance
Protection against electromagnetic environment effects
Outside plant
Data Networks and Open System Communications
Characteristics of telemetric systems
Groupings cont
Television and sound transmission
Languages and general software aspects for telecommunications system
Signally requirements and protocols
End-to-End transmission performance of networks and terminals
General Networks Aspects
Transport Networks, systems and equipment
Multimedia services and systems
Broadband
The ITU-T responsible for broadband standards based on ATM technology.
The ATM forum – contributes to ATM standards
Process
Working in 4 year cycles
Meetings of a world telecommunication standardization conference
Work program for next cycle established
Study groups created and abolished
Process decided submitted questions (results in more groups)
There is an accelerated procedure (1988)
allowing recommendations to be approved when they are ready
Ballot process overview
Wide participation by governments, users and industrial representatives and by consensus decision making
-Therefore significant delays
This is now actively being streamlined via a majority rule ballot
-Significantly end users, vendor are represented on the forum
Institute of Electrical and Electronic Engineers (IEEE)
Maintaining Standard
Initiating Project
Mobilizing the Working Group
Drafting standard
Balloting Standard
Gaining Final Approval
Initiating the Project
Driven by sponsors input to a collaborative group
A Project Authorisation Request (PAR) is produced
-Why is it required
-What is it going to do
Working Group
-PAR approved
-Works to create and write standards
-Anyone can be included in the group
Drafting the Standard
-Develop first draft
-Mandatory Editorial coordinator checks the draft (layout specification checked only)
-Goes to ballot
Balloting
Once the sponsor decides the standard is stable
Sponsor creates balloting group
-But anyone can comments
Balloting group consist of:
-Producers
-Users
-Government
-General Internet
Balloting lasts 30-60 days
Decisions:
-Approve
-Disapprove
-Abstain
-Consensus = 75% respondents with 75% of that group approval
Gaining approval
The IEEE-SA standards Board approves the final standard or not
The decision is based on recommendations from the review committee
Standards are valid for 5 years
-After which they can be:
-Reaffirmed
-Revised
-Withdrawn
Maintaining Standards
Formal interpretations highlight areas for consideration in future revisions.
