IETF - Areas of Work Patrik Fältström Area Director, Applications Area Document IPW-8 ©Patrik Fältström 2000

What are we doing? ¢ Work is done in Working Groups – – – ¢ ©Patrik Fältström 2000 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 ¢ ¢ ¢ ¢ ©Patrik Fältström 2000 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 ©Patrik Fältström 2000

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 ¢ ©Patrik Fältström 2000 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 ¢ ©Patrik Fältström 2000 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 ©Patrik Fältström 2000

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" ¢ ©Patrik Fältström 2000 Layering issues must be resolved!

Layers in the IETF? ¢ Telephone call – Addressing, routing, Qo. S ¢ Transport mechanism – Connection oriented ("a call") ¢ ITU? IP layer IETF? – Addressing, routing ¢ Link layer, UMTS, GPRS – Addressing, routing, Qo. S ©Patrik Fältström 2000 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? – Qo. S is one such issue ¢ How do we reuse technologies? – Fax. IP is email of TIFF image ©Patrik Fältström 2000

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 ¢ ¢ ©Patrik Fältström 2000 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> ©Patrik Fältström 2000
