Abstract
A method for classifying different pages accessed by a web-browser into different service-levels on a granularity finer than that of the connection. The method augments each edge device with two applications, a Client-Proxy and a Server-Proxy. The Client-Proxy obtains identifying information from the client's request, and the obtain PICS labelling information from a label referee. This information is used to obtain a service level from an LDAP based SLA directory, and this service level information is then imbedded along with a unique identifier for the network operator organization in the HTTP header request which is transferred to the Server-Proxy. The Server-Proxy then strips the header containing the PICS information from the request and forwards the request to the server. When the Server-Proxy gets a response, it uses the PICS information to mark the packets.
