Use Cases and API Extension for Source IP Address Selection
draft-sijeon-dmm-use-cases-api-source-06.txt
Abstract
This draft specifies and analyzes the expected cases regarding the
selection of a proper source IP address and address type by an
application in a distributed mobility management (DMM) network. It
also proposes a new Socket API to address further selection issues
with three source IP address types defined in the on-demand mobility
API draft.

1. Introduction
Applications to select source IP address type in a mobile node (MN)
need to consider IP session continuity and/or IP address
reachability. [I-D.ietf-dmm-ondemand-mobility], defines three types
of source IP addresses based on mobility management capabilities:
fixed IP address, session-lasting IP address, and non-persistent IP
