Problems solved by technology

[0009] In the prior art, after the service connection is established, these service attribute parameters of the OTU unit may not be configured. At this time, the service attribute parameters can be manually configured, but the configured service attribute parameters are inconsistent, and some parameters do not support configuration and default The business attributes of the two clients are inconsistent, so even if the connection between the two clients is established, the business cannot be delivered

Embodiment Construction

[0038] The embodiment of the present invention provides a port attribute parameter negotiation method, including: obtaining port information of a first node and a second node in the network, the port information includes: port attribute parameters; when the first node, the second node When the port attribute parameters of the nodes are inconsistent, and the port attribute parameters of at least one of the first node and the second node are configurable, adjust the configurable port attribute parameters of the second node and / or the first node to make the first node The port attribute parameters of the node and the second node are the same. Wherein, the port attribute parameters of the first node and the second node are the optical port attribute parameters of the source client and the target client, respectively; or, the port attribute parameters of the first node and the second node are the access of the source client, respectively The service attribute parameters of the optical ...

Abstract

The invention discloses a method for consulting port attribute parameters, a network node and a network system. The method for consulting port attribute parameters comprises the following steps: port information of a first node and a second node in the network is obtained, wherein the port information comprises port attribute parameters; and when the port attribute parameters of the first node and the second node are inconsistent and the port attribute parameter of the first node or the second node can be configured, the configurable port attribute parameter of the second node and / or the first node is adjusted to lead the port attribute parameters of the first node and the second node to be consistent. The technical scheme of the invention can ensure normal business transferring after connection is established.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a port attribute parameter negotiation method, a network node and a network system. Background technique [0002] WDM network is the core of future wide area network and metropolitan area network, including: Optical Terminal Multiplexer (OTM), Optical Line Amplifier (OLA), Optical Add / Drop Multiplexer (Optical Add-Drop Multiplexer, OTM) / Drop Multiplexer, OADM) and electrical relay network element (Regenerator, REG), their networking forms are as figure 1 Shown. [0003] The OTM is placed in the terminal station and can be divided into the sending part and the receiving part. The sending part is to perform optical wavelength conversion, multiplexing, and combining of the optical signals output by multiple client devices into a single optical fiber for amplification and transmission. The receiving part separates all channels transmitted in one optical fiber, and then sends them...
