Service data transmission method and system in optical network

The invention relates to a service data transmission method and system in an optical network. The method comprises the following steps: a first edge controller receives a service data transmission request sent by each source node in a first edge network; the first edge controller determines service data needing to be bundled and transmitted, the service data needing to be bundled and transmitted corresponds to a second edge network, and the second edge network corresponds to a second edge controller; the first edge controller, the central controller and the second edge controller perform cooperative path calculation and determine a service data transmission path; and the first edge controller, the central controller and the second edge controller respectively send a path establishment instruction to nodes in the service data transmission path to finish establishment of the service data transmission path and transmit service data. Binding transmission of service data of different sources or different homes can
