eap Mailing List: Re: Issue 376: Proposed Resolution (Section 1.1)

[Bernard Aboba (bernard_aboba]

  Decorated NAI

     A NAI specifying a source route.  See RFC4282 [RFC4282] Section
     2.7 for more information.

[BA] "RFC4282" -> "RFC 4282"

  Realm

     Realm portion of an NAI [RFC4282].

[BA] Change to "The realm portion of..."

  Network Selection

     This refers to selection of an operator/ISP in order to access the
     network.  The process of network selection can occur either at the
     beginning of a new session or during a handoff in case the user is
     mobile.  The selection is dependent upon for example the selection
     of realm for the operator, authentication credentials for the
     user/device and the roaming agreements.  The realm Selection can
     in turn also depend upon Access Technology Selection and/or Bearer
     Selection.

[BA] I don't understand how network selection can occur at the beginning
of a session -- doesn't it need to occur before the session begins?
Also, I don't understand how network selection can occur during an L2
handoff.  The "realm" of an operator doesn't make sense -- isn't a
realm is a characteristic of the home AAA server? Suggest rewriting to:

     Selection of an operator/ISP for network access.  Network Selection
     occurs prior to network access authentication.

  Network Discovery

     This refers to a mechanisms that a node uses to discover available
     networks prior the realm selection takes place.  The discovery
     process may be passive or active from a node point of view.
     Typically the discovery mechanism varies depending on the access
     technology.  It is also possible that there are multiple discovery
     mechanisms within one access technology depending on the network
     deployment.

[BA] Suggest rewriting to:

     The mechanism used to discover available networks. The discovery
     mechanism may be passive or active, and depends on the access
     technology.  In passive network discovery, the node listens for
     network announcements; in active network discovery the node
     solicits network announcements.  It is possible for an access
     technology to utilize both passive and active network discovery
     mechanisms.

  Realm Selection

     This refers to selection of the realm of the operator/ISP used to
     access the network.

[BA] This doesn't make sense to me -- the realm is a characteristic of
the home AAA server.  Suggest rewriting to:

The selection of the realm (and corresponding NAI) used to access the
network.

  Network Access Server

     The Network Access Server (NAS) is the device that clients connect
     to in order to get access to the network.  In PPTP terminology,
     this is referred to as the PPTP Access Concentrator (PAC), and in
     L2TP terminology, it is referred to as the L2TP Access
     Concentrator (LAC).  In IEEE 802.11, it is referred to as an
     Access Point.

[BA] I would change to:

  Network Access Server

     The device that peers connect to in order to obtain access to the
     network.  In PPTP terminology,
     this is referred to as the PPTP Access Concentrator (PAC), and in
     L2TP terminology, it is referred to as the L2TP Access
     Concentrator (LAC).  In IEEE 802.11, it is referred to as an
     Access Point.
