Embodiment Construction

[0046] The embodiments of the present application may be applied to a transport network, such as an optical transport network (optical transport network, OTN). For example, the optical transport network may adopt a distributed automatically switched optical network (automatically switched optical network, ASON) technology. The architecture of the optical transport network can be a mesh network. The mesh network refers to a multi-hop network. Each network node in the mesh network can send and receive signals, and each network node can communicate with a Or multiple network nodes communicate directly.

[0047] In this embodiment of the present application, a network node may also be referred to as a network element or a network device, and a network device may be a device that provides a routing and forwarding function in a network, for example, a router, a switch, a repeater, or a label switching router (label switching router). router, LSR), etc., without limitation. In the ...

Abstract

The invention discloses an information transmission method, an information transmission device and a network node, which are used for solving the problem of resource waste. Specifically, control plane topology discovery of a routing protocol is decoupled from diffusion of a TE LSA bearing TE link state information of a data plane, and when the TE link state information of the data plane is diffused, the TE link state information is diffused to a service head node in a point-to-point mode according to a planned shortest path tree. The service head node can be a predetermined network node which needs to know TE link state information of other network nodes. Therefore, resource waste caused by the adoption of a flooding diffusion mode is reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of communications technologies, and in particular, to an information transmission method, an apparatus, and a network node. Background technique [0002] In the optical transport network, each node needs to maintain the topology data of the entire network, such as each node and the connection links between each node, the waveform or channel data of each link, and so on. When the state of a node changes and it is desired to send the changed data of the device to the target node, the data is generally sent to the target node by flooding. Specifically, the data is first transmitted to each neighbor node. , and then each neighbor node retransmits the data to its own neighbor node (except the node that sends the data), and the relay repeats until the data is transmitted to the target node hop by hop. In the flooding method, a node may receive duplicate data from multiple neighbor nodes for the ...
