Problems solved by technology
In this way, at least nodes 13 and 16 need to maintain two FlexE paths (i.e., FlexE path 1 and FlexE path 2), thereby causing an increase in the management complexity of edge forwarding nodes B1 and B2 and maintaining the signaling overhead brought by the FlexE path increase

Embodiment Construction
[0034] The technical solution in this application will be described below with reference to the accompanying drawings.
[0035] The nodes involved in this application, such as network devices such as the first source node, the first destination node, and the first forwarding node, may be routers or switches.
[0036] The "next node of node A" in the present application refers to a node directly connected to node A through FlexE along the direction of the FlexE path and is a downstream node of node A. For example, the next node of the first forwarding node refers to a node that is directly connected to the first forwarding node through the FlexE and is a downstream node of the first forwarding node. It should be understood that along the direction of the FlexE path, there is no intermediate node between node A and the next node of node A.
[0037] The "previous node of node A" in this application refers to a node that is directly connected to node A through FlexE along the dir...

The invention provides a flexible ethernet (FlexE) path establishment method and network equipment. The management complexity and the signaling overhead of the control plane of nodes can be reduced. The method comprises the steps that a first forwarding node receives a first path establishment request message transmitted by a first source node, wherein the first path establishment request messageis used for establishing a first FlexE path from the first source node to a first destination node, and the first FlexE path is used for transmitting first business flow; the first forwarding node establishes a second FlexE path from the first forwarding node to a second forwarding node according to the first path establishment request message and deletes the established third FlexE path from thefirst forwarding node to the second forwarding node after establishing the second FlexE path; and the first forwarding node establishes and saves the corresponding relationship of the first FlexE pathand the second FlexE path so that the first business flow and the second business flow are enabled to be mapped to the time slot of the second FlexE path.
Description
technical field [0001] The present application relates to the field of flexible Ethernet, and more specifically, to a method and network device for establishing a Flexible Ethernet (FlexibleEthernet, FlexE) path. Background technique [0002] Flexible Ethernet is an Ethernet technology developed on the basis of traditional Ethernet. The FlexE technology can realize the bandwidth isolation of different flexible Ethernet client (FlexE Client) services on the port. Therefore, this technology can also be applied to the Internet Protocol (Internet Protocol, IP) Ethernet network to ensure specific Service quality (Quality of Service, QoS) of the business. For example, Node 11, Node 13, Node 14, Node 16, and Node 17 are connected through FlexE, and an end-to-end FlexE path (or channel (Channel)) between Node 13 and Node 16 passing through Node 14 can be established. To carry the service flow 1 whose source node is node 13 and destination node is node 16, and by establishing an en...
