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.

Abstract translation: 一种新型的数据传输服务，其使用帧中继层2数据链路连接标识符（DLCI）来在各种服务类型，特征集和/或封闭用户组（CUG）之间进行选择。 层3地址可以从第2层提取，并且层3地址信息可以用于根据所选择的服务类别，特征集和/或CUG在分组交换网络上路由数据分组。 在目的地，层3数据分组可以再次被封装在具有指示服务类别，特征集合和/或CUG的DLCI的层2帧中。 因为在本发明的方面不需要使用传统的永久虚拟电路（PVC），所以提出了测量和管理网络流量的新方法。
