MIF API consideration
draft-ietf-mif-api-extension-05
Abstract
Hosts may connect to the internet using more than one network API at
a time, or to a single network on which service is provided by more
than one provider. Existing APIs are inadequate to allow
applications to successfully use the network in this environment.
This document presents a new abstract API that provides the minimal
set of messages required to enable an application to communicate
successfully in this environment.

1. Introduction
Traditionally, applications that communicate on the network have done
so over a single network link, which is provided by a single service
provider. However, this operating environment is now the exception
rather than the rule. Most devices now have multiple wireless
interfaces that are, in practice, connected to networks operated by
different providers. These networks may or may not have different
reachability characteristics with respect to any given service an
application may wish to connect to.
