The IESG has approved the following document: - 'Distributed Mobility Management: Current practices and gap analysis' (draft-ietf-dmm-best-practices-gap-analysis-09.txt) as Informational RFC This document is the product of the Distributed Mobility Management Working Group. The IESG contact persons are Brian Haberman and Ted Lemon. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-dmm-best-practices-gap-analysis/ Technical Summary The present document analyzes deployment practices of existing IP Mobility protocols in a distributed mobility management environment. The analyzed IP level (i.e., layer 3) mobility protocols include those developed by IETF and also those developed by other SDOs that have been widely deployed. Due the plurality of different mobility enabling protocol and solutions, the analysis has been intentionally limited to IP level (i.e., layer 3) protocol that typically are based on some sort of tunneling solution. The document then identifies existing limitations when compared to the distributed mobility management requirements defined in draft-ietf-dmm-requirements for a distributed mobility management solution. On the existing IP mobility enabling architectures (outside mobile VPNs or IETF defined IP mobility solutions), the document considers only the 3GPP GPRS/EPS system and service provider Wi-Fi due their dominant positions in the market place. Working Group Summary The document creation was not entirely smooth as seen from the timeline. There are several aspects in the existing deployments making use of IP mobility (such as the 3GPP GPRS/EPS) that already today include many enhancements on the deployment & product feature level that can be seen as a step towards distributed mobility management. The line between what is a gap and what can be achieved with today's tools was not always exactly clear. However, the WG has an agreement on the gaps described in this document and the fact that the most prevalent solutions that exist are not defined in IETF and are specific to certain system architectures. Document Quality There are no implementations of this document, since it only presents an analysis of existing protocols and deployments to what is intended to be achieved with distributed mobility management. The document has received multiple thorough reviews in the WG. Personnel Jouni Korhonen (jouni.nospam@gmail.com) is the document shepherd. Brian Haberman (briad@innivationslab.net) is the AD.
