Method for supporting different service levels in a network using web page content information
First Claim
1. In a network connected to clients by intermediate nodes, a method of differentiating priority of access to an internet web server based on content of web pages being accessed, comprising the steps of:
- storing ratings independent of client input of web pages at a node on the network;
on receipt of a client request for a web page, determining at an intermediate node a rating for said web page, said determination being made by lookup at said rating storage node;
converting, at said intermediate node, said rating to a service class by looking up said rating at an Lightweight Delivery Access Protocol (LDAP) directory node;
selecting, for use of said intermediate node, a mechanism for providing differentiated services according to said service class.

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.
