1. Introduction
With the various kind of promising wireless broadband access
technologies, there are more possbilities that mobile node could have
multiple connections which may provide different kind of service
available.
In some cases, the operator would like to let the mobile node to know
what kind of services it allow or doesn't allow in this connection.
It may influence network routing,policy and quality of service, et
al. consideration.

3. Option usage
There are various kind of wireless broadband access technologies, one
mobile node may has multiple wireless cards, subscriber may choose
different connection for different service. So a DHCPv6 server may
provide a list of service identifiers option to different clients.
The mobile node will decide which service may take which connection
based on this advertisement of this dhcp option.
This option could be advertised to dhcp client after authentication
procedure to guarantee eligible subscriber could get this
information.
