Problems solved by technology

[0003] The existing technology has the following disadvantages: the interface configuration information is added to the road construction signaling, and the interface configuration is performed during the road construction process, resulting in a long time for the establishment of the entire path, and when the dynamically created interface needs to be released, it must be removed first It takes a long time to release the established connection and then release the interface, and the RSVP-TE protocol needs to be expanded, thus increasing the complexity of the path establishment signaling

Embodiment 1

[0025] see figure 1 , the embodiment of the present invention provides a method for establishing a path in a multi-layer network, which specifically includes:

[0026] In step 101: the source node (i.e. the node that initiates the interface configuration) sets the interface configuration information, which includes the parameters of the source node interface and the destination node interface, specifically, it can be the IP address of the source node interface, the IP address of the destination node interface, One of subnet mask, gateway, identifier of flooding interface parameters, identifier of participating resource reservation, name of AS (Autonomous System, Autonomous System) domain to which the source node belongs, and name of AS domain to which the interface of the destination node belongs or a combination of multiple types of information.

[0027] In step 102: the source node sends a call message to the destination node, initiates a call authentication process, and ca...

Embodiment 2

[0046] see image 3 , an embodiment of the present invention provides a network node. In this embodiment, as a source node for initiating interface configuration, the node specifically includes:

[0047] The transceiver module 301 is used to send a call message to the destination node, the call message carries interface configuration information, and is also used to receive a call response message returned by the destination node, and the call response message carries the interface configuration performed by the destination node according to the interface configuration information after the result;

[0048] The establishment module 302 is configured to judge whether the destination node configures the interface successfully according to the call response message received by the transceiver module 301, and if yes, establish a connection path with the destination node.

[0049] Among them, the interface configuration information is the interface IP address of the source node, t...

Embodiment 3

[0054] see Figure 4 , the embodiment of the present invention also provides a network node. In this embodiment, as the destination node in the interface configuration process, the node specifically includes:

[0055] A receiving module 401, configured to receive a call message carrying interface configuration information sent by a source node;

[0056] The authentication module 402 is configured to perform authentication according to the call message received by the receiving module 401. If the authentication passes, configure the interface of the network node according to the interface configuration information in the call message, and return the authentication success and carry The call response message of interface configuration success information is sent to the source node, and if the authentication fails, the call response message of authentication failure is returned to the source node.

[0057] The interface configuration information in this embodiment is the interfa...

Abstract

The invention discloses a method for establishing a path in a multilayer network, a network node and a system, and belongs to the technical field of networks. The method comprises the following steps: sending call message which carries interface configuration information to a destination node, and receiving call response message returned by the destination node, wherein the call response message carries a result after the destination node carries out interface configuration according to the interface configuration information; and judging whether the configured interface of the destination node is successful according to the call response message, if so, carrying out interface configuration at local, and then establishing a connection path with the destination node. One network node comprises a transceiving module and an establishing module. The other network node comprises a receiving module and an authentication module. The system comprises a source node and the destination node. The method, the network node and the system improve the efficiency of interface configuration, shorten the switching-on time of a service path, realize separation of dynamic interface configuration and establishing connection process, are simple and convenient and easy to realize, and have good expandability.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for establishing a path in a multi-layer network, a network node and a system. Background technique [0002] In a multi-layer network composed of IP (Internet Protocol, Internet Protocol) network and OTN (Optical Transport Network, Optical Transport Network), each layer of the network is independently planned and resource allocated, and service provisioning requires each layer to be configured separately. When establishing an end-to-end MPLS-TE (Multiple Protocol Label Switch-Traffic Engineering, Multi-Protocol Label Switching Traffic Engineering) connection, if a layer-by-layer cross-layer service provisioning method is adopted, it is necessary to consider the internal and The constraint relationship between networks is very complicated, and the configuration efficiency is low and time-consuming. Multi-layer control technology can be used to realize automatic opening ...
