Abstract
A route processing method includes obtaining, by a first network device, a flow effective time parameter and a route related to the flow effective time parameter, processing, by the first network device in the specified time interval, service traffic corresponding to the route related to the flow effective time parameter, generating a route control message, where the route control message carries the flow effective time parameter and the route, and sending, by the first network device, the route control message to a second network device.
Claims28
A method, implemented by a first network device, wherein the method comprises:
- obtaining a flow effective time parameter and a route related to the flow effective time parameter, wherein the flow effective time parameter comprises a start time value and a duration value, and wherein the flow effective time parameter indicates that the route is effective in a time interval specified by the flow effective time parameter;
- generating a message carrying the flow effective time parameter and the route, wherein the message indicates a second network device to process service traffic corresponding to the route in the time interval, and wherein the message is an extended Border Gateway Protocol (BGP) update message;
- and
- sending the message to the second network device.
A method, implemented by a second network device, wherein the method comprises:
- receiving a message from a first network device, wherein the message carries a flow effective time parameter and a route related to the flow effective time parameter, wherein the flow effective time parameter comprises a start time value, a duration value, a first duration type, and a first period value, wherein the flow effective time parameter indicates that the route is effective in a time interval specified by the flow effective time parameter, and wherein the message is an extended Border Gateway Protocol (BGP) update message;
- and
- processing, in the time interval, service traffic corresponding to the route according to the message.
A first network device, comprising:
- a non-transitory memory configured to store instructions;
- and
- one or more processors coupled to the non-transitory memory, wherein the instructions cause the one or more processors to be configured to:
- obtain a flow effective time parameter and a route related to the flow effective time parameter, wherein the flow effective time parameter comprises a start time value and a duration value, and wherein the flow effective time parameter indicates that the route is effective in a time interval specified by the flow effective time parameter;
- generate a message, wherein the message carries the flow effective time parameter and the route, wherein the message indicates a second network device to process service traffic corresponding to the route in the time interval, and wherein the message is an extended Border Gateway Protocol (BGP) update message;
- and
- send the message to the second network device.
A second network device, comprising:
- a non-transitory memory configured to store instructions;
- and
- one or more processors coupled to the non-transitory memory, wherein the instructions cause the one or more processors to be configured to:
- receive a message from a first network device, wherein the message carries a flow effective time parameter and a route related to the flow effective time parameter, wherein the flow effective time parameter comprises a start time value, a duration value, a first duration type, and a first period value, wherein the flow effective time parameter indicates that the route is effective in a time interval specified by the flow effective time parameter, and wherein the message is an extended Border Gateway Protocol (BGP) update message;
- and
- process, in the time interval, service traffic corresponding to the route according to the message.
