Problems solved by technology

If you want to ensure the correct configuration, you need to know the PVC encapsulation format of the CPE connected to the remote end, and configure it port by port, which increases the complexity of configuration.
[0012] In addition, the existing technology cannot support user-defined rules for distinguishing service flows, and can only be distinguished according to the existing COS, VLAN, and encapsulation types

Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] The core of the present invention is to combine ATM flow classification and IP flow classification, and when the service processing unit in the IP DSLAM receives the user side message, it first classifies the ATM flow according to the AAL5 encapsulation type of the ATM message. Then IP flow classification is further performed. During IP flow classification, matching can be performed according to one or more specified fields of the Ethernet packet encapsulated in the bridged ATM packet, and the successfully matched service flow can be mapped to corresponding different S-VLANs. For IPoA or PPPoA encapsulated packets, perform single-service matching, and map the successfully matched service flow to the corresponding S-VLAN.

Abstract

The invention relates to communication field, and discloses sorting disposal method for business flow and the technique of the classification of ATM flow and classification of IP flow can be blend, single PVC singe-business mode and single PVC multi-businesses can be coexisted in same PVC. In the invention, the classification of ATM flow and classification of IP flow are combined, and the ATM flow is classified according to the packing type of AAL5 of ATM message, if it is the bridge packing, then the classification of IP flow are processed. The classification of IP flow can match with one or more appointed fields of message of Ethernet network. When the IP flow is been classifying, it can adopt the COS, VLAN, field of packing type, the user-defined rule as well.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a service stream classification technology in a Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access Multiplexer, "DSLAM" for short). Background technique [0002] With the large-scale use of Asymmetric Digital Subscriber Line (Asymmetry Digital Subscriber Line, referred to as "ADSL") access and the wide application of Internet Protocol (Internet Protocol, referred to as "IP") technology in the field of communication, the IP core The Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access Multiplexer, referred to as "DSLAM" device) for IP uplink has been greatly recognized. [0003] The principle of IP DSLAM is to realize the conversion from Asynchronous Transfer Mode (ATM) to IP, and to realize the permanent virtual channel (Permanent Virtual Channel, referred to as "PVC") to Media Access Control (Medium Access Control, "MAC" for sh...
