Traffic management for frame relay switched data service
First Claim
1. A method, comprising:
- managing according to a committed delivery rate one of a plurality of actual network transmission rates for one active source of a plurality of active sources, the committed delivery rate being associated with a destination; and
reserving a first portion of network bandwidth for a first inactive source to allow the first inactive source to begin to send data packets through a network at a rate that exceeds a first reference rate.

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.
