Problems solved by technology

[0006] It can only provide point-to-point path transmission. For point-to-multipoint path transmission, it is split into multiple point-to-point path transmission methods. The transmission network bandwidth is redundant and the bandwidth utilization rate is low, resulting in transmission costs. Problems such as high cost and low transmission efficiency

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] In the embodiment of the present invention, the aggregation node detects the state of the connected active and standby communication devices, transmits services to it in the active state, and passes through services in the backup state, thereby protecting the transmission of services and saving bandwidth, especially In the service transmission of MSTP (SONET / SDH), DWDM / CWDM, etc. as the bearer network, it effectively protects the transmission of services such as multiplay.

[0026] One end of the active / standby communication device in the embodiment of the present invention is connected to the core network, and the other end is connected to the transmission network through a convergence node. It can be MSCG, which is mainly used ...

Abstract

The invention discloses a method for protecting a transmission service and a sink node thereof, which belong to the field of network transmission. The method comprises the following steps: a sink node that is connected with main / standby communication devices detects the operating states of the main / standby communication devices and judges whether the detected states of the main / standby communication devices are the duty state; if yes, the service is transmitted between the sink node and the main / standby communication devices; if the detected states are the backup state, the service directly reaches through the sink node and is transmitted to the next sink node. The sink node comprises a detecting module, a judging module, a transmitting module and a reach-through module. The method ensures the reliability of the service transmission, ensures the simple operation and the low development cost of the service transmission, greatly reduces the transmission band width, increases the band width utilization rate, reduces the transmission cost and the running / maintenance cost, and improves the network reliability. The method and the sink node are widely used for the transmission of the point-to-multipoint backup service.

Description

technical field [0001] The invention relates to the field of network transmission, in particular to a method for protecting transmission services and a convergence node. Background technique [0002] The rapid development of broadband services, especially multiplay (Multiplay) services, has put forward new transmission requirements for the transmission network. see figure 1 , is a schematic diagram of broadband transmission services. DSLAM (Digital Subscriber Line Access Multiplexer, digital subscriber line access multiplexer) or other multi-user access equipment, such as Ethernet switches, cable modem access servers, PON (Passive Optical Network, passive optical network) optical Line terminals, etc., are connected to end users, and after accessing services, they are converged and transmitted through MSTP (Multi-Service Transmission Platform) or DWDM (DenseWavelength Division Multiplexing) transmission network, and then sent to MSCG (Multi-Service Transmission Platform). ...
