Frame relay switched data service
First Claim
1. A network comprising:
- customer premises equipment;
a frame relay switch coupled to the customer premises equipment with at least one permanent virtual circuit and receiving a plurality of frame relay data packets, the frame relay switch for translating user data within at least one of the frame relay data packets into a fast packet address;
wherein the frame relay switch is responsive to a plurality of different service categories, said plurality of different service categories is supported over a plurality of different types of communication paths, and configured to determine a quality of service of the plurality of different service categories responsive to layer 4 data, wherein said plurality of different types of communication paths comprises at least two of;
a public internet, a local intranet, or an extranet.

Abstract
A new type of data transport service which uses a frame relay layer 2 data link connection identifier (DLCI) to select among various service types, feature sets, and/or closed user groups (CUGs). A layer 3 address may be extracted from a layer 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.
