Providing quality of service (qos) in a network environment in which client connections are maintained for limited periods of time

Abstract

A method and apparatus are provided for implementing Quality of Service (QoS) in a network environment in which client connections are maintained for limited periods of time. According to one embodiment, packet forwarding devices of a network, such as routers, bridges, and Local Area Network (LAN) switches, are caused to forward packets associated with a client according to a particular class of service, e.g., best-efforts, premium service, associated with the user of the client by assigning a network address, e.g., an Internet Protocol (IP) address, to the client based upon the particular class of service. According to another embodiment, a method of configuring the packet forwarding devices in a network is provided. For each class of service supported, information identifying one or more ranges of network addresses that are to receive a particular measure of service associated with the class of service is communicated to the packet forwarding devices. According to yet another embodiment, a network includes one or more packet forwarding devices, a network address assignment server, and a network administration terminal. The network address assignment server is configured to receive a connection request initiated by a client, to identify a particular class of service that is accessible to a user of the client, and to assign a network address corresponding to the particular class of service to the client. The network administration terminal configures the one or more packet forwarding devices to perform packet forwarding according to the classes of service supported by identifying, for each class of service, a pool of network addresses that are to receive a particular measure of service associated with the class of service. The pools of network addresses each contain one or more ranges of network addresses from a network address space allocated to the network.
