Abstract
This application relates to example service configuration methods and example apparatuses. In one example method, a first optical transport network (OTN) device receives a first message from an optical line terminal (OLT) device, where the first message includes first address information of a service. The first OTN device determines, based on the first message, whether a first path has been established in an OTN, where the first path is used to transmit data of the service, and the first path satisfies the first address information. The first OTN device establishes a path for transmitting data of the service or adjusts a bandwidth of the established first path based on a result of the determining.
Claims18
A service configuration method, comprising:
- receiving, by a first optical transport network (OTN) device, a first message from an optical line terminal (OLT) device, wherein the first message comprises first address information of a service;
- determining, by the first OTN device based on the first message, whether a first path has been established in an OTN, wherein the first path is used to transmit data of the service, and the first path satisfies the first address information, wherein the determining, by the first OTN device based on the first message, whether a first path has been established in an OTN comprises:
- determining, by the first OTN device, second address information based on the first address information, wherein the second address information comprises a source device identifier, a destination device identifier, and a slot number of the first path in the OTN;
- and
- determining, by the first OTN device based on the second address information, whether the first path has been established in the OTN;
- and
- establishing, by the first OTN device, a path for transmitting data of the service or adjusting a bandwidth of the established first path based on a result of the determining.
A service configuration method, comprising:
- receiving, by an optical line terminal (OLT) device, a first signaling from a terminal device, wherein the first signaling is used to request to configure a service;
- and
- sending, by the OLT device, a first message to a first optical transport network (OTN) device, wherein the first message is used to determine a path of the service in an OTN, and the first message comprises first address information of the service, wherein second address information is determined based on the first address information, wherein the second address information comprises a source device identifier, a destination device identifier, and a slot number of a first path in the OTN, and wherein the second address information is used to determine whether the path of the service has been established in the OTN.
An optical transport network (OTN) device, comprising:
- a transceiver;
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
- receive, by the transceiver, a first message from an optical line terminal (OLT) device, wherein the first message comprises first address information of a service;
- determine, based on the first message, whether a first path has been established in an OTN, wherein the first path is used to transmit data of the service, and the first path satisfies the first address information, wherein determining, based on the first message, whether the first path has been established in the OTN comprises:
- determining second address information based on the first address information, wherein the second address information comprises a source device identifier, a destination device identifier, and a slot number of the first path in the OTN;
- and
- determining, based on the second address information, whether the first path has been established in the OTN;
- and
- establish a path for transmitting data of the service or adjust a bandwidth of the established first path based on a result of the determining.
