- This is a rough draft - Megan 04/20/92
-
- Mobile Hosts BOF, Chaired by Steve Deering, Notes by Kevin Rowett
- San Diego IETF March 18, 1992
-
- Agenda
-
- Status of group to change from BOF to working group
- (not completed, pending charter submission by chair to
- area director).
-
- Reports from related groups
- Review Columbia specification for mobile internetworking
- goal to publish as an Internet Draft
- DHCP implications and requirements.
- Carl Auerbach wants to speak about some vague notions.
-
-
- No report from the IEEE 802.11 group. To get on the mail list for 802.11
- documents, contact the 802.11 chair, Vic Hayes (Vic.Hayes@Utrecht.ncr.com).
-
- Charter presented for benefit of recent new members:
-
- - develop/adopt architectures and protocols to support
- mobile hosts in the Internet.
- - convey Internet mobility concerns/ideas to other relevant
- working groups and standards bodies.
-
- Scope of Work:
-
- - issues above media access layer: addressing/naming/routing/bridging.
- - issues beyond Dynamic Host Configuration: roamers and temporarily
- relocated hosts.
- - mobile hosts, mobile networks, mobile internetworks.
- - cellular and general topologies, with and without wired infrastructure.
- - mobility across multiple link layers (wired and wireless).
- - multi-protocol, as well as IP-only.
- - impact on higher layers, e.g., transport.
- - accommodation of sleeping (battery-saving) and off-line hosts.
-
- Outside of Scope:
-
- - solutions that do not interoperate with existing Internet systems.
- - issues of delay- or jitter-sensitive traffic, or other
- quality-of-service concerns (should be orthogonal to mobility).
- - congestion avoidance/control (ditto).
- - header or packet compression (ditto).
- - privacy (ditto); however, authentication is within scope.
-
- John Ioannidis presented his mobile networking architecture (see
- accompanying viewgraphs). He, Dan Duchamp, and Gerald Maguire have
- produced a draft spec for the architecture and protocols, for possible
- publication as an RFC. (A subset of the attendees of this BOF met later
- in the week for a thorough review of the document. After an editing pass,
- the document will be made available as an Internet Draft, which the group
- may then choose to recommend for submission as an RFC.)
-
- Carl Auerbach spoke for about fifteen minutes about how he saw the realm
- of mobile computing being used and some of his experiences at Sun.
-
- * traffic is mobile to a fixed host.
- * optimized base station to base station to allow easier
- "mobiling" of a users environment.
- * it's really people that are mobile, not the machines. People
- want to take their environment with them.
-
- Steve Deering discussed possible DHCP implications of the Columbia
- mobile routing scheme:
-
- * concept of portable IP addresses.
- * which subnet to assign mobile host to.
- * vendor extensions to be used for IP address attributes.
-
- These concerns will be presented to the DHC working group for their
- consideration.
