Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail according to the drawings and examples below.

[0027] Such as image 3 As shown, the networking structure is that a central multicast source switch is set up at the central node, and only a single-fiber IP multicast signal is output from the SFP module. The signal is divided into two channels through the electrical cross-connection capability of the OTN network. One channel is the signal from OTN equipment A to OTN equipment B station. At the same time, the other channel crosses through to the next OTN equipment C; the other routes the signal from OTN equipment A to OTN equipment D. After the signal reaches OTN equipment D, OTN equipment D divides the signal Lower-level service switching 3, and another channel crosses through to the next OTN device C, and passes the signal back to the OTN device A of the central node, OTN device A→OTN device B→OTN device C→OTN device D and OTN device A...

Abstract

A method for broadcasting IP multicast signals on an OTN network, the steps are: a central node sets up a central multicast source switch, and sends out received IP data source information in the form of an IP multicast stream; forcibly activates the central multicast source switch The port of the SFP enables the IP multicast stream signal to enter the OTN equipment access port of the central node of the OTN network; sends the IP multicast stream signal to the OTN equipment at each sub-site in the ring; the service OUT optical port of the OTN equipment at the sub-site communicates with the The IN port of the SFP module of the lower-level service switch is connected; the lower-level service switch broadcasts the IP data source information to the lower-level service switch; the terminal device accesses the IP data source information through the lower-level service switch. The invention can improve the utilization rate of the OTN network channel, save equipment cost and line resources, have high stability and safety, and strong practicability, and is an innovative application of the OTN network.

Description

technical field [0001] The invention relates to a method for realizing a two-way data transmission mode by using one-way broadcasting, in particular to a method for broadcasting an IP multicast signal on an OTN network. Background technique [0002] With the vigorous development of video, data services, and large-grain private lines, higher requirements are placed on line bandwidth. The SDH backbone network with a traditional 10G bandwidth capacity is gradually weakening in the face of diversified and high-bandwidth services. , most operators have built their own OTN trunk transmission network to meet the increasing business needs of expansion. [0003] With the improvement of the integration of IP equipment, the increase of bandwidth, and the diversification of transmission equipment support, digital TV transmission IP brings highly intensive equipment, high concentration of information, and flexible business scheduling. It is a trend in the development of digital televisi...
