  • Sharing of NAS information between PoPs
    Patent number: 7529826
    Abstract: A method for handling access requests at multiple PoPs using the sharing of NAS information between the PoPs, enabling each PoP to maintain its own, independent, database of user records. When an access request is received, it is forwarded to a specific PoP designated as the user's “home PoP”. This home PoP is the only PoP to contain the user's records. The home PoP may then handle the access request by utilizing a local NAS list, the local NAS list being synchronized with other NAS lists in the network and providing information on all the “known” NASes throughout the entire network. This allows for a user to roam between PoPs, while reducing the bandwidth and security concerns that have existed in the past when users chose to roam. The NAS lists may then be updated via a central Network Control Console.
