[edit] Architecture of Met-Wi

Architecture
  • A site-to-site VPN will be used to connect two UCLA research centers, the network at the LA SHP and the portable system.
  • We will use four class C subnets to allow each client device on the network to act as a directly-accessible server.
  • The network will use Cisco products and general purpose hardware.
  • The network will be able to locate and track client devices and hence verify and attest location reported by clients.
  • Thus, will be used as a framework to build Mediator services for time/location attestation and data scrubbing, as well as services for auditing data.

[edit] MetWi Notes

APs are given "static" addresses assigned by DHCP.

  • This is done using DHCP binding to MAC address through SDM.
  • Also removed these addresses from DHCP pool so they are not given accidentally to some other host.
