A data flow redirection method to overcome a disadvantage that a quantity of adjustable data flows is relatively small due to limited space of a flow specification forwarding table. The method includes receiving, by a network device, a control message sent by a control device, where the control message carries redirection routing information of a data flow and a redirection routing indication, the redirection routing indication instructing to convert the redirection routing information of the data flow into a forwarding entry in a target forwarding table, and tablespace of the target forwarding table is greater than tablespace of a flow specification forwarding table of the network device, and converting, by the network device, the redirection routing information of the data flow into the forwarding entry in the target forwarding table according to the redirection routing indication.

Data flow redirection method and system, network device, and control device

A method, includes receiving a packet flow optimization policy including a flow identifier of a target packet flow, a device identifier of a to-be-adjusted forwarding device, and information about the next hop; obtaining status information of an access control list (ACL) of the to-be-adjusted forwarding device based on the device identifier, where the status information includes resource usage status information of the ACL and capability information that indicates whether the to-be-adjusted forwarding device supports packet flow forwarding that is based on the ACL; and when determining, based on the status information, that the ACL includes an idle resource and the to-be-adjusted forwarding device supports packet flow forwarding that is based on the ACL, sending an ACL record to the to-be-adjusted forwarding device, where the ACL record includes the flow identifier and the information about the next hop.

Forwarding path adjustment method, apparatus, and system

A method of route convergence, a routing device, and a main control board in the routing device are provided herein. The method includes receiving route information from multiple neighbor routing devices; selecting a route among the received route information, and applying the selected route to update an FIB of the main control board; and delivering the selected route to an interface board after confirming that the route information from the multiple neighbor routing devices is received and the route selection is completed.

Method of route convergence, routing device, and main control board in routing device

A method, device, and system for processing Border Gateway Protocol (BGP) route are provided, which relate to the field of network communication technologies. The method includes: receiving a BGP route sent by a BGP neighbor; obtaining a route prefix of the BGP route according to the BGP route; determining, according to the route prefix, a BGP route storing and processing module corresponding to the route prefix; and sending the BGP route to the determined BGP route storing and processing module, so that the BGP route storing and processing module processes the received BGP route. A device and a system for processing BGP route are also provided. Therefore, the processing efficiency of the BGP route is improved, and the high extensibility is realized.

Method, device, and system for processing border gateway protocol route

A method for route updating includes: a. determining more than one route in accordance with a predetermined preset mechanism and sending the determined more than one route to a client and/or a non-client, by a reflector in a route advertisement, and saving more than one route reaching the same destination address by the client and/or the non-client; and b. sending to the client and/or the non-client a message carrying information on the next hop of the route to be withdrawn, by the reflector in a withdrawal of a route and withdrawing the corresponding route for route updating in accordance with the information on the next hop carried in the message, by the client/the non-client. A system for route updating and a router reflector is also provided.
