Hi,
The specific passage from the new draft that I wanted the wg to
see is the following (with references to AERO removed). Please
review and send questions or comments.
Thanks - Fred

3. A Day in the Life of an Enterprise Mobile Device User
An enterprise network mobile device user ("Bill") begins his workday
by seating his primary end user device (EUD) (e.g., a laptop computer,
a tablet, a smart phone, etc.) in a docking station at his office desk
and turning the device on. The docking station connects Bill's EUD to
the enterprise wired LAN, and the EUD receives a Topologically-Fixed
Address (TFA) from the infrastructure. Bill's EUD further discovers
the DMM service within the enterprise network and requests a Topology
Independent Prefix (TIP)delegation. Bill's EUD receives the same TIP
delegation it gets every time it connects to the enterprise network,
because the DMM service has an administratively set mapping between
the TIP and Bill's EUD device ID.
Bill's EUD can then access topologically-fixed enterprise services
using its TFA directly, and can access DMM services by using an
address from its TIP as the source address for tunneling over the
enterprise network. As Bill's workday unfolds, his EUD uses the DMM
service to correspond with other EUDs in peer-to-peer sessions, join
lengthy virtual conferencing sessions, access enterprise fileshares,
etc. The DMM service ensures that optimal routes are maintained so
that tunneled communications flow over direct paths and network
infrastructure elements are not unnecessarily over-burdened.
While communications sessions such as the video conference are still
in progress, Bill leaves the office to attend a meeting in a nearby
conference room. He disconnects his EUD from the docking station and
in the process drops his connection to the wired LAN. The EUD
quickly enables a WiFi interface that searches for a Service Set
Identifier (SSID) that can provide wireless access within the
enterprise network. The EUD authenticates itself to the network via
the SSID using its pre-loaded certificates, and uses a securing
mechanism such as IEEE 802.1x to assure Confidentiality, Integrity
and Availability (CIA). The EUD receives a new TFA from the network,
then communicates its new TIP-to-TFA association to the DMM service
and any active peer correspondents. Any ongoing communications
sessions will continue to see the same (stable) TIP.
Bill then leaves the enterprise campus to attend an off-site customer
meeting with his EUD still powered on and actively seeking to
maintain network connectivity. As Bill departs from the building,
the WiFi signal fades until it can no longer support communications,
and the EUD quickly enables a 4G cellular wireless interface that
connects Bill's EUD to a cellular service provider. The EUD then
locates the Internet address of an enterprise network security
gateway and initiates a VPN session with the gateway (which also acts
participates in the DMM service). The DMM service updates the routing
system, and Bill can continue to use the same TIP that was assigned
to his EUD when he started his workday even though the EUD is now
communicating over a VPN configured over the public Internet instead
of over the secured campus LAN.
Bill subsequently arrives at the customer meeting at a public
restaurant with a WiFi hotspot. His EUD quickly powers up its WiFi
interface and powers down the 4G interface. The EUD uses DMM
signaling to communicate the new TFA to the security gateway and the
VPN survives the mobility event. Moreover, the EUD can continue to
use the same TIP it received at the beginning of the workday, and
ongoing communication sessions can continue until Bill explicitly
discontinues them.
After the customer meeting, Bill leaves the restaurant and
subsequently passes through several additional transitions from WiFi
hotspots to 4G wireless. Again, the DMM service keeps the VPN
session alive, and the TIP assigned to the EUD remains in continuous
use in active communication sessions as well as to allow Bill to
receive notifications and process urgent requests. When Bill returns
to his office, the EUD discontinues use of the VPN while keeping its
TIP active after re-attaching to the campus LAN.
Bill ends his workday, powers down his EUD and returns home. Bill
powers on his EUD to check e-mails, and connects to the enterprise
network via a VPN configured over his home ISP service. The EUD
again receives the same TIP that it used within the enterprise
network domain, and Bill can access DMM services the same as if he
was in the office. Bill finally shuts down for the evening, and
begins his next workday in the same fashion. Again, the EUD receives
the same TIP as always regardless of the access network point of
connection over which the EUD enters the enterprise.
