Embodiment 1

[0066] In the present invention, it is assumed that there are three kinds of devices in a typical home broadband access network: access device, switch and gateway device. Wherein, the access device may be a CEP broadband access device. The CEP broadband access equipment accesses data services, voice services, IPTV and VOD services of home users. When the above-mentioned services are sent to the access switch, they carry their respective service VLAN identifiers, and the data service, voice service and VOD service use different service VLAN identifiers. It should be noted that both the IPTV service and the VOD on-demand service are connected to the CEP broadband access device through the set-top box STB, and use the same service VLAN ID.

[0067] like figure 1 As shown, the present invention provides a method for service uplink forwarding, the method comprising:

[0068] Step S101: the switch receives the message sent by the access device, and the message carries the service...

Embodiment 2

[0114] The uplink forwarding and downlink forwarding of the service of the present invention will be further described below in conjunction with the accompanying drawings.

[0115] In this embodiment, the home user mixed service accesses the switch B through the CEP broadband access device A, and finally reaches the gateway device C.

[0116] like Figure 5 As shown, service uplink forwarding can be performed in the following manner:

[0117] When performing service upstream forwarding, CEP broadband access device A sends various mixed service packets to access switch B, with tag 1 for data packets, tag 2 for voice packets, and tag 3 for IPTV and VOD service packets.

[0118]Switch B uses a VFP (Vlan Filter Processor, label filter processor) rule to add different user VLAN IDs to the message after matching the port PORT+service VLAN ID of the message. Wherein, the service VLAN ID is an inner layer ID, and the user VLAN ID is an outer layer ID. The outer user VLAN ID of a da...

Abstract

The invention provides a service uplink forwarding method which comprises the steps of receiving a message by a switch, wherein the message is transmitted by an access device and carries a service virtual local area network (VLAN) identification; adding a user VLAN identification into the message by the switch, and transmitting the message to gateway equipment. The invention further provides a service downlink forwarding method which comprises the steps of receiving the message by the switch, wherein the message is transmitted by the gateway equipment and carries the service virtual local area network (VLAN) identification and the user VLAN identification; after the switch analyzes the message, transmitting the analyzed message to the access device, wherein the analyzed message only carries the service virtual local area VLAN identification. The service uplink forwarding method, the service downlink forwarding method, the service uplink forwarding device and the service downlink forwarding device realize uplink and downlink forwarding in accessing a plurality of services which carry different service VLAN identifications, and furthermore realize uplink and downlink forwarding in accessing an IPTV service and a VOD service which carry the same service VLAN identification.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and a corresponding device for uplink forwarding and downlink forwarding of services. Background technique [0002] Medium and low-end switches in enterprise networks have always played an important role in the field of broadband access to homes in metropolitan area networks. With the continuous increase of user demands, the types of switch access services are also continuously increasing. Common main services include common data services, voice services, IPTV (Internet Protocol Television, interactive network TV) and VOD (Video on Demand, video on demand) services, etc. Then, the mixed access method of these different types of services is It has naturally become one of the main contents of the research in the field of switches.Generally speaking, different business access switches can use different Vlans, so that switches can use Vlan (Virtual Local Area...
