Problems solved by technology

Since the number of NEs in an MPLS-TP network is often large, and each NE includes a large number of inbound interfaces, the workload of configuring IP addresses for the inbound interfaces of all NEs in the MPLS-TP network is heavy and cumbersome. It is easy to make mistakes during configuration; and, running the ARP protocol on the network element will occupy a large amount of CPU (Central Processing Unit, central processing unit) utilization rate of the network element, thereby affecting the processing speed of the network element

Embodiment 1

[0086] An embodiment of the present invention provides an Ethernet interface addressing method in an MPLS-TP tunnel. The execution body of the method is a controller, which can centrally control the network and is deployed on an independent server; the controller can specifically For computers or servers, etc. see Picture 1-1 , the method includes:

[0087] Step 101a: The controller obtains the inbound interface information from the first network element to the second network element in the transmission subset MPLS-TP tunnel path based on multi-protocol label switching to be established, and the second network element in the MPLS-TP tunnel path The element is the next-hop network element of the first network element;

[0088] Step 102a: The controller acquires the media access control MAC address of the incoming interface from the first network element to the second network element according to the incoming interface information from the first network element to the second n...

Embodiment 2

[0096] An embodiment of the present invention provides an Ethernet interface addressing method in an MPLS-TP tunnel. The execution subject of the method is a controller, and the controller may be a system that centrally controls the network and is deployed on an independent server; the controller specifically It can be a computer or a server. see diagram 2-1 , where the method includes:

[0097]Step 201: The controller receives a tunnel establishment request, and the tunnel establishment request carries parameters of a source node, a destination node, and a tunnel;

[0098] When a user sends an MPLS packet, an MPLS-TP tunnel path for transmitting the MPLS packet needs to be established in the MPLS-TP network. At this time, the client-side device or the head node sends a tunnel establishment request to the controller. The tunnel establishment request carries The source node, the destination node, and the parameters of the tunnel, where the tunnel parameters may be the bandwi...

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an Ethernet interface addressing method, device, controller and network element in an MPLS-TP (Multi-Protocol Label Switching Transport Profile, transmission subset based on Multi-Protocol Label Switching) tunnel. Background technique [0002] MPLS-TP is a transmission technology that combines MPLS packet switching and traditional transport network features. MPLS-TP provides MPLS-TP tunnels for data packet transmission. MPLS-TP tunnels are composed of more than two network elements and connections between different network elements. Data packets can be transmitted between these network elements. When an MPLS-TP tunnel is used to transmit an MPLS packet, when a network element in the MPLS-TP tunnel sends the MPLS packet, the network element obtains the information of the incoming interface of the next-hop network element in the MPLS-TP tunnel MAC (MediaAccess Contr...
