A computer configured to serve data services in a one-way cable plant having telco-return for upstream data resources to requesting computers in a networked environment is disclosed. The computer includes a subscriber edge services manager server and a radius proxy server, the radius proxy configured to classify received radius requests into a plurality of types and handle requests classified as a first type from requests classified as non-first types. The computer also includes an access point, the access point providing communication connection to at least one computing device. The subscriber edge services manager server and radius proxy server are configured to communicate with the access point to acquire information from the access point, and user location information is configured on the access point in a vendor-specific attribute.

Support for WISPr attributes in a TAL/CAR PWLAN environment

A user device disposed on a local area network (LAN) requests a proxy auto-configuration file from a first proxy server. Where the first proxy server is not present on the LAN, a second proxy server on the LAN intercepts the request and responds to it by causing a replacement proxy auto-configuration file to be sent to the user device. The user device utilizes the replacement proxy auto-configuration file to configure itself to utilize the second proxy server on the LAN.

Method and apparatus for emulating web browser proxies

A method is disclosed for policy-based determination of a network address for a client in a network. A request for a network address is received from a client. A policy response is received that identifies a scope of network addresses for the client. A request source address value in the client request is modified, based on the policy response. The modified client request is sent to a server that can assign network addresses within the identified scope. A network address for the client is received, which has been assigned by the server within the identified scope. The network address is provided to the client. A specific embodiment modifies a 'giaddr' field value in a DHCP request, before relaying the request to a DHCP server, based on a policy decision that specifies a scope to be used for the network address of the client.

Method and apparatus providing policy-based determination of network addresses

A system manages communications between a user and a network by receiving a user request for access to a network file during a user network connection session with a connecting network, determining whether the user has a connected user session state or a disconnected user session state with respect to a portal server, responding to a disconnected user session state by determining a user identity that specifies a physical location for the user and providing the user with a redirected page for display in a user graphical interface program in accordance with the determined user physical location user identification and in accordance with service selection information, and then changing the user session state to a connected state, and responding to a connected user session state by routing the user request for access to the network file to a network server. The system thereby controls user access to web pages, but does not require any specialized client-side software, and permits different content to be delivered according to the location of the user who will receive it.
