ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains to data access network systems. More particularly, this invention relates to a system and method for allowing a data service system within a data access network system to classify user access requests such that the data service system can provide class-based services to its users.
2. Description of the Related Art
An example of a data access network system is an Internet/Intranet network system. An Internet/Intranet network system typically includes a data service system and an interconnect network that connects the data service system to subscriber or user terminals or to other data service systems. The data service system is typically referred to as an Internet/lntranet Service Provider (ISP) system. The ISP system can host a number of content sites. The ISP system can also be connected to other ISP systems via an interconnect network, thus forming the Internet/Intranet network system. The users connected to the ISP system can access the content sites within the ISP system or the content sites within the other ISP systems via the network.
An ISP system typically includes web and/or content servers that host contents for various customers or applications. The customers are the owners of the contents hosted in the ISP system such that subscribers or users can access the contents via their computer terminals. The content servers typically utilize Internet applications, such as electronic mail, bulletin boards, news groups, and World Wide Web access. The hosted contents are arranged in the form of content sites within the content servers. Each site may include a number of pages (e.g., world wide web pages). A content site is typically for one customer while a particular customer may own a number of content sites.
Disadvantages are associated with this prior approach. One disadvantage is that the ISP system is not equipped to give different processing treatments to the users accessing a web site within the ISP system. As is known, the ISP system can be accessed by multiple users to a single web site at the same time. The ISP system typically handles the user access requests for that web site in the first-come-first-served (FIFO) fashion. This means that all of the users of the ISP system receive the same and equal treatment and no preferential treatment is allowed for any class of users. As a result, the ISP system does not support class-based service which allows access requests for the same content site to receive different processing treatments.
SUMMARY OF THE INVENTION
One feature of the present invention is to allow a data service system to provide different treatments to the users of the data service system.
Another feature of the present invention is to allow a data service system to control when an access request will be accepted for processing or rejected by the data service system.
A further feature of the present invention is to allow a data service system to prioritize access requests into classes such that preferential treatments can be given to some of the users accessing the data service system.
A still further feature of the present invention is to allow a data service system to provide a class-based service server.
A data service system includes at least one content site that is accessible through a plurality of access requests. The data service system includes a user access request classification system. The user access request classification system includes a request classifier that classifies each of the access requests into one of a plurality of classes based on a predetermined classification policy. The user access request classification system also includes a plurality of buffers coupled to the request classifier. Each buffer corresponds to one of the classes to receive the access requests classified by the request classifier as belonging to that class such that the data service system processes the access requests in accordance with their classes.
A method of classifying user access requests for a content site in a data service system is also described. The method includes the step of classifying each of the access requests into one of a plurality of classes based on a predetermined classification policy. The access requests belonging to each of the classes are then stored in a corresponding buffer such that the data service system processes all the access requests in accordance with their classes. The data service system includes a plurality of buffers, each corresponding to one of the classes specified by the classification policy.
Other features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.
