Abstract
A bandwidth information notification method includes: obtaining bandwidth information of a microwave link; and sending a plurality of OAM messages carrying the bandwidth information to an endpoint, wherein first one or more OAM messages of the plurality of OAM messages are sent more quickly than at least one of the rest of the plurality of OAM messages.
Claims18
A bandwidth information notification method, comprising:
- obtaining, by a network node, bandwidth information of a microwave link;
- determining, by the network node according to the obtained bandwidth information, that a bandwidth of the microwave link has changed;
- in response to determining that the bandwidth of the microwave link has changed, sequentially sending, by the network node, a first plurality of operation, administration and maintenance (OAM) messages carrying the bandwidth information to an endpoint;
- after sending the first plurality of OAM messages carrying the bandwidth information to the endpoint, sequentially sending, by the network node, a second plurality of OAM messages carrying the bandwidth information to the endpoint, wherein the OAM messages of the second plurality of OAM messages are periodically sent one at a time using a normal period, and wherein OAM messages of the first plurality of OAM messages are periodically sent one at a time using a period that is smaller than the normal period.
1 more element
A network node, comprising:
- an obtaining unit, configured to obtain bandwidth information of a microwave link;
- a sending unit, configured to:
- when a bandwidth of the microwave link has changed, sequentially send a first plurality of operation, administration and maintenance (OAM) messages carrying the bandwidth information obtained by the obtaining unit to an endpoint;
- and
- after sending the first plurality of OAM messages, sequentially send a second plurality of OAM messages carrying the bandwidth information to the endpoint, wherein OAM messages of the second plurality of OAM messages are periodically sent using a normal period, and wherein OAM messages of the first plurality of OAM messages are periodically sent one at a time using a period that is smaller than the normal period.
2 more elements
A communication system, comprising:
- a network node;
- a first endpoint;
- and
- a second endpoint, wherein the first endpoint and the second endpoint are endpoints of a service connection that passes through a microwave link and the network node;
- wherein the network node is configured to obtain bandwidth information of the microwave link, and to sequentially send a first plurality of operation, administration and maintenance (OAM) messages carrying the bandwidth information to the first endpoint in response to determining that a bandwidth of the microwave link has changed;
- wherein the network node is further configured to, after sending the first plurality of OAM messages to the first endpoint, sequentially send a second plurality of OAM messages to the first endpoint, wherein the first plurality of OAM messages is sent more quickly than the second plurality of OAM messages, and wherein the first endpoint is configured to adjust a service policy according to the bandwidth information.
3 more elements
A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor to perform operations comprising:
- obtaining, by a network node, bandwidth information of a microwave link;
- in response to determining that a bandwidth of the microwave link has changed, sending, by the network node, a first plurality of operation, administration and maintenance (OAM) messages carrying the bandwidth information to a first endpoint;
- after sending the first plurality of OAM messages to the first endpoint, sending, by the network node, a second plurality of OAM messages carrying the bandwidth information to the first endpoint;
- wherein the first endpoint is an endpoint of a service connection between the first endpoint and a second endpoint, wherein the service connection passes through the microwave link and the network node;
- and
- wherein OAM messages of the second plurality of OAM messages are periodically sent using a normal period and wherein OAM messages of the first plurality of OAM messages are periodically sent using a period that is smaller than the normal period.
