Abstract: A network access point for locally processing an access request is configured to include an information bus, an access event publisher, and at least one local cache having at least one user record. The access event publisher publishes at least one network access event on the information bus during the processing of the access request. The first local cache is coupled to and is responsive to the network access event by updating the user record according to information contained by the network access event if the information includes a home access point ID that corresponds to the first local cache. The network access point may be part of a communications system having a mother cache. The mother cache is coupled to the first local cache and includes user records of subscribers supported by the communications system.

Abstract: An information broker is provided which receives information regarding the updating of IP addresses and distributes the information to subscribing Domain Name Service (DNS) or Dynamic Host Configuration Protocol (DHCP) servers. A list of subscribing servers is maintained by the broker. The broker may broadcast information regarding the allocation of a IP addresses to subscribing DNS servers, which then may be added to the DNS databases or the database may be updated with the new information. The broker may also broadcast information regarding the revocation of IP addresses to subscribing DNS servers, which may then be used to clear DNS entries in the database. Revocation of dynamically allocated IP addresses in networks with multiple DHCP servers may also be simplified by using the broker, where the broker broadcasts information regarding the revocation of IP addresses to subscribing DHCP servers.

Abstract: The present invention is a method and apparatus for providing the owners of domain sites on a computer network or the owners of private remotely accessible intra networks the capability to force authorized users to disconnect from any open connections to other public or private domains or networks before a connection with the owners domain or network can be established. This forced sequential access of a specified domain or network is accomplished by inserting a sequential-only attribute into the service profile for a specified user. Upon the user initiating a log-on sequence through an access point, the user's service profile is pulled from a memory bank and an assessment is made as to whether or not the sequential-only attribute exists for the desired specified domain or network to be accessed.

Abstract: A method and apparatus for providing computer network access points the capability for multiple-level accounting. A gateway device located at the access point is capable of generating Internet protocol accounting start and stop requests based on various events that need to be accounted for when a user accesses a network. These events include the user account logon, the service establishments and the Point to Point protocol (PPP) connections between the gateway device and public and private domains within the network. The counter is capable of tracking the duration of sessions and connections and the byte-count associated with the specified session or connection. The gateway device communicates with an accounting server which stores the accounting requests and matches start requests with subsequent stop requests.
