Problems solved by technology

[0008] Although the CPE 135 and 145 can be constructed simply with many different physical ports and large memory, this CPE is not economical for customers
Furthermore, such CPEs do not scale well where customers expect many different channels or logical ports on the same physical ingress or egress port

Abstract

A system and method for classification of data units in a network device acts as a bridge in heterogeneous networks, provides many different services and provisions many different transport mechanisms. The data classifier generates an ID that is internally used by the network device in managing, queuing, processing, scheduling and routing to egress the data unit. This internal ID enables the device to accept any type of data units from any physical / logical ports or channels and output those data units on any physical / logical ports or channels that are available. The device utilizes learning on a per-flow basis and can enable the device to identify and process data units used in private line services and private LAN services.

Description

technical field [0001] Generally, the present invention relates to telecommunications and digital networking. In particular, the invention relates to the classification of packets in heterogeneous data redirection networking equipment. Background technique [0002] In digital networking and telecommunications, data is often assembled and then transmitted and received in definite discrete units known as packets. All or a specific number of packets originating from the same source device, connection or application can be aggregated together in a "flow". Although the term "packet" is used in this discussion, "packet" may also refer to other discrete units of data, such as frames or the like. Network devices (such as switches, routers, etc.) that intercept and forward such flows or packets are often configured with multiple ingress ports (that is, the port where the input flow arrives at the device) and multiple egress ports (that is, the input flow is routed out of the devic...
