Â (Abstract from "Detection of Network Attachment (DNA) in IPv4")
Â The time required to detect movement (or lack of movement) between
Â subnets, and to obtain (or continue to use) a valid IPv4 address may
Â be significant as a fraction of the total delay in moving between
Â points of attachment.Â This document synthesizes experience garnered
Â over the years in the deployment of hosts supporting ARP, DHCP and
Â IPv4 Link-Local addresses.Â A procedure is specified for detection of
Â network attachment in order to better accommodate mobile hosts.
Â The document addresses a need for compilation of experiences with
Â various protocol specifications and formal description of protocol
Â operation based on those experiences.Â Members of the dhc WG
Â provided significant expert input based on experience with DHCP
Â client/server deployment and operation.
Â - Working Group Summary
Â The dhc WG was actively involved in the development of this
Â document and provided significant input.Â The consensus of the WG
Â is to submit the document for publication.Â The issues raised
Â during discussion of this document, including the WG last call, are
Â listed at http://www.drizzle.com/~aboba/DNA/
Â - Protocol Quality
Â This document does not define a protocol; rather, it provides a
Â formal description of procedures for host movement that are useful
Â in protocols like DHCP and IPv4 link-local addresses.Â The quality
Â of the document is excellent.
