IETF - Areas of Work Patrik Fältström Area Director, Applications Area Document IPW-8
What are we doing? • Work is done in Working Groups • Specified by charters • Specification + Work Items • Work items according to timeline • Internet-Drafts do not specify what the IETF is doing, among them are though working documents for the working groups
Areas in the IETF • Applications • General • Internet • Operations and Management • Routing • Security • Transport • User Services
Specifics • IETF works with a layered modular model, with IP in the middle • IP on top of something • Something on top of IP • Communication between layers • Reuse of existing solutions
IESG Liasons • IAB Keith Moore • SC2 Harald Alvestrand • SC6 Allison Mankin • SC21 Harald Alvestrand • SC29 Harald Alvestrand • ATM Forum Andy Malis • ITU Scott Bradner • Unicode Patrik Faltstrom • OECD Donald Eastlake • W3C Keith Moore • WIPO Patrik Faltstrom
Specifically for ITU • FAX over Internet • SG8 • Media Gateway Control • SG16 • PSTN and Internet Internetworking • SG11
Other contacts • Telephone Number Mapping • SG2 • Service in the PSTN/IN Requesting Internet Service • SG11 • Signaling Transport • Multiparty Multimedia Session Control • Audio/Video Transport • IP Telephony • Session Initiation Protocol • Internetworking Over NBMA • Electronic Data Interchange-Internet Integration …and maybe some more...
New work in the IETF • Anyone can propose a WG • Normally they first get a BOF • IESG decide if it looks ok • Question goes to "new-work" list and IETF as a whole • Input is requested - also from ITU • Overlapping, not clear enough charter, impossible milestones, forgotten issues, just plain stupid • IESG then makes a decision
When wg exists • Liason can be appointed • Contact point for information to/from other organization • Liasons appointed in pairs • Org A assigns Foo as liason to B • Org B assigns Bar as liason to A • Documents should only be created in one of the organizations, and referenced from the other
Not carved in stone • Exactly how liasons and wg work has changed from wg to wg • It depends on how the wg work, and what the wg do • We are still trying to find the way of cooperation which creates minimal friction • We eq IETF and ITU
New areas • "Parallel" technologies like WAP • Is this because "glue" between layers in the IETF is not good enough? • New carriers of IP • UMTS, GPRS • Addressing, IP and lower layers • Routing of IP, and "application" • Layering issues must be resolved!
Layers in the IETF? • Telephone call • Addressing, routing, QoS • Transport mechanism • Connection oriented ("a call") • IP layer • Addressing, routing • Link layer, UMTS, GPRS • Addressing, routing, QoS ITU? IETF? ITU?
No borders! • We need to cooperate • Several things are • Clearly IETF • Clearly ITU • Note that addressing was mentioned in many layers • E.164 number, IP address, wireless end node identifier • How do we create correct glues? • QoS is one such issue • How do we reuse technologies? • FaxIP is email of TIFF image
What is NNR? • Depends on what layer one talk about • One do easily create "layering violation" • Mix up link address with IP address with name for example • Decide before starting discussing • Or, is the NNR discussion a meta discussion by itself?
Contact points • Don't hesitate contacting IESG, or rather, relevant Area Directors • http://www.ietf.org • Contacts from ITU should be coordinated, if possible Patrik Fältström <paf@swip.net>
