A bandwidth adjustment method is disclosed. The source node receives an adjustment command issued by a network management server, all nodes on the path are triggered to adjust a forward transmission bandwidth parameter of the Optical Service Unit (OSU) respectively, so the network management server does not need to issue adjustment commands to all the nodes on the path, thereby simplifying the process of the bandwidth adjustment. Further, the source node enters an adjustment mode corresponding to the OSU, and sequentially sends the first message to the downstream node until the sink node, so that each node on the path enters the adjustment mode corresponding to OSU, and then exits the adjustment mode corresponding to the OSU after performing corresponding adjustment on the forward transmission bandwidth parameter of the OSU, thereby realizing a synchronous adjustment of all nodes on the path based on the adjustment mode corresponding to the OSU.

Provided are a service transmission method and device using a FlexO, equipment and a storage medium. The method includes: customer service data is mapped into N FlexO frames on M Physical Layer links of a FlexO transmission group, and then the N FlexO frames are sent through the FlexO transmission group; and a receiving end sequentially extracts the customer service data from the N FlexO frames. The FlexO transmission group comprises M PHY links. The customer service data occupies the same number of cells in the FlexO frame of each PHY link, and cell locations of the occupied cells are the same. A set of logic is used to directly map the customer service data into the N FlexO frames on the M PHY links of the FlexO transmission group, so as to minimize complexity and logical resources needing to be occupied.

Service transmission method and device using flexible optical network, equipment and storage medium

A method, device and system for synchronization message transmission are provided. The method may include that: a transmitting end selects at least one Ethernet Physical Layer Link (PHY) for synchronization message transmission from a Flexible Ethernet (FlexE) group (S); after encapsulating the synchronization message according to a preset encapsulation strategy, the transmitting end inserts the synchronization message into a synchronization message channel in overhead of the selected Ethernet PHY (S); and the transmitting end transmits the synchronization message through the selected Ethernet PHY (S).
