Problems solved by technology

[0007] In the process of realizing the present invention, the inventors found that the PSN network in the 1+1 protection mode in the prior art has at least the following problems: each service data must be protected by 1+1 throughout the entire network from the source to the sink; The online bandwidth occupation is twice the actual bandwidth of its business data, causing serious waste of network resources and high network operating costs; CE is required to implement dual transmission and dual reception, and the requirements for CE capabilities are relatively high

Embodiment 1

[0032] A schematic structural diagram of an apparatus for transmitting business data of a client device provided in this embodiment is as follows image 3 As shown, including: PE1.

[0033] PE1 is connected to CE2 through the working link, connected to CE1 through AC1, and connected to PE2 through the connection channel D-PW. When the working link is normal, PE1 is the main aggregation device, and when the working link fails, it is the standby aggregation device. Specifically, it may include: a first main processing module and a second main processing module, and may also include a third main processing module, a first backup processing module and a second backup processing module.

[0034] Wherein, the first active processing module is configured to, when the working link is normal, after receiving the service data sent by the CE1 through the AC1, perform emulation and encapsulation processing on the service data, Send the service data to the CE2 through the working link;

Embodiment 2

[0040] A schematic structural diagram of a system for transmitting service data of a client device provided in this embodiment is as follows Figure 4 As shown, including: CE1, CE2, PE1, and PE2.

[0041] CE2 is connected to PE1 through the working link in the PSN network, and connected to PE2 through the protection link in the PSN network. If the working link is normal, the service data is transmitted between the working link and PE1. At this time, PE1 is the main aggregation device, and PE2 is the backup aggregation device; if the working link fails, the service is transmitted between the protection link and PE2. Data, at this time, PE2 is the main aggregation device, and PE1 is the standby aggregation device.

[0042] PE1 is connected to CE2 through a working link, connected to CE1 through AC1, and connected to PE2 through a connection channel D-PW. The D-PW can be a direct physical or logical link. The above-mentioned D-PW can be used for service data forwarding, status ...

Embodiment 3

[0058] A schematic structural diagram of a system for transmitting service data of a client device provided in this embodiment is as follows Figure 5 shown. exist Figure 5 Among them, BSC (base station controller, base station controller) and BTS (base transceiver station, base transceiver station) are used as CE equipment, BSC is dual-homed to PE1 and PE2 through AC1 and AC2, and BTS is connected to PE3 through Ethernet (Ethernet) . A PW is configured between PE1 and PE3 as a working PW, and PW OAM (Operation, Administration and Maintenance) is configured on this PW for alarm detection; a PW is configured between PE2 and PE3 as a protection PW, and this Configure PW OAM on the PW to detect alarms. When the OAM detects that the working PW fails and the protection PW is normal, PE3 switches services to the protection PW. Under normal conditions, PE1 is the main aggregation device for dual-homing protection, and PE2 is the standby aggregation device for dual-homing protect...

Abstract

The invention provides a method and a system for transmitting service data of client equipment. The method mainly comprises the following steps: PE1 (Provider Edge) receives service data sent from CE1 (Customer Edge) via AC1 (Access Circuit); when an active link is normal, the PE1 sends the service data to the CE2 via the active link; and when the active link fails, the PE1 sends the service data to the PE2 via a connection channel, so that the PE2 sends the service data to CE2 via a protective link. According to the method and the system, communication between CE1 and CE2 has a PE1 and PE2 double-node protective function; in addition, protocol negotiation is not needed among PE1, PE2 and CE1, thereby improving communication reliability.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device and system for transmitting service data of client devices. Background technique [0002] At present, the MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) technology has been widely deployed not only in the core network, but also in the metropolitan area mobile bearer network. Both traditional fixed network telecommunication services (such as voice) and mobile network services are increasingly transferred to PSN (Packet Switching Network, Packet Switching Network) based on MPLS. [0003] According to PWE3 (Pseudo Wire Emulation Edge-to-Edge, end-to-end pseudowire emulation) technology, whether it is TDM (Time Division Multiplex, time division multiplexing), SDH (Synchronous Digital Hierarchy, synchronous digital system) / SONET (Synchronous Optical Network , optical fiber synchronous network), frame relay and other tradi...
