  1. Location Configuration Protocols: How many more do we need? “This protocol aims to allow an end host to obtain location information, by value or by reference, from a Location Information Server (LIS) that is located in the access network.” http://www.ietf.org/internet-drafts/draft-ietf-geopriv-l7-lcp-ps-00.txt Marc Linsner

  2. Location Configuration • Network based vs. host determined • Location is a layer 2 problem • Layer 1 & 2 attributes dictate that location is derived here • Location is *local* network pertinent information • Network hosts are advised of local information via configuration protocols • DHCP, LLDP, and CDP are protocols used to advise hosts of local network parameters

  3. Layer 2 is involved • Regardless of whether there is a static wiremap database or exotic rf measurement technology, layer 2 is involved in discovering the physical location of a host. • Layer 2 media access control protocols are being modified to pass location information to a host within it’s control plane (LLDP-MED, 802.11tgv??)

  4. Is a layer 7 mechanism required? • A layer 7 LCP is a business issue, not a technical issue. • A layer 7 LCP can mask poor network design • A layer 7 LCP provides many new attack vectors • Internet experience shows that complex mechanisms fail and easy/simple ones are utilized.

  5. Internet Architecture • Internet applications separate the access layers from the application layers. This is at the heart of the Internet’s success Common point - The end device! VoIP, Inc. (Application Service Provider) Layer 7 ISP, Inc. (Internet Service Provider) Layer 3 Last Mile, Inc. (Access Provider) Layer 2
