©Patrik Fältström 2000 What are we doing? Work is done in Working Groups 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 Internet-Drafts do not specify what the IETF is doing, among them are though working documents for the working groups

©Patrik Fältström 2000 New work in the IETF Anyone can propose a WG Anyone can propose a WG –Normally they first get a BOF IESG decide if it looks ok IESG decide if it looks ok Question goes to "new-work" list and IETF as a whole Question goes to "new-work" list and IETF as a whole Input is requested - also from ITU Input is requested - also from ITU –Overlapping, not clear enough charter, impossible milestones, forgotten issues, just plain stupid IESG then makes a decision IESG then makes a decision
©Patrik Fältström 2000 When wg exists Liason can be appointed Liason can be appointed Contact point for information to/from other organization Contact point for information to/from other organization Liasons appointed in pairs 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 Documents should only be created in one of the organizations, and referenced from the other
©Patrik Fältström 2000 Not carved in stone Exactly how liasons and wg work has changed from wg to wg Exactly how liasons and wg work has changed from wg to wg It depends on how the wg work, and what the wg do 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 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 "Parallel" technologies like WAP –Is this because "glue" between layers in the IETF is not good enough? New carriers of IP New carriers of IP –UMTS, GPRS Addressing, IP and lower layersAddressing, IP and lower layers Routing of IP, and "application"Routing of IP, and "application" Layering issues must be resolved! Layering issues must be resolved!
©Patrik Fältström 2000 Layers in the IETF? Telephone call Telephone call –Addressing, routing, QoS Transport mechanism Transport mechanism –Connection oriented ("a call") IP layer IP layer –Addressing, routing Link layer, UMTS, GPRS Link layer, UMTS, GPRS –Addressing, routing, QoS ITU? ITU? IETF?
©Patrik Fältström 2000 No borders! We need to cooperate We need to cooperate Several things are Several things are –Clearly IETF –Clearly ITU Note that addressing was mentioned in many layers Note that addressing was mentioned in many layers –E.164 number, IP address, wireless end node identifier How do we create correct glues? How do we create correct glues? –QoS is one such issue How do we reuse technologies? How do we reuse technologies? –FaxIP is of TIFF image
©Patrik Fältström 2000 What is NNR? Depends on what layer one talk about Depends on what layer one talk about One do easily create "layering violation" One do easily create "layering violation" –Mix up link address with IP address with name for example Decide before starting discussing Decide before starting discussing Or, is the NNR discussion a meta discussion by itself?
