Abstract

A method for managing information, the controller generates a first message carrying the address of a first next hop of a network device, the first message includes first identification information, and the first identification information is used to indicate that the network The device deletes the entry of the first next hop corresponding to the address of the first next hop from the next hop table saved by the network device. The network device receives the first message, and deletes the entry of the first next hop according to the indication of the first identification information. The next hop information is sent separately from the controller to the network device without carrying routing prefix information, and the unavailable next hop can be revoked, which effectively saves the system resources occupied by the interactive revoking routing message between the controller and the network device, and improves the efficiency. business processing efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method, device and system for managing information. Background technique [0002] In recent years, the value of software-defined network (English: Software Define Network, SDN) has been recognized by telecom network operators, and it is the evolution direction of future networks. The SDN system includes a controller and a network device, wherein the controller can be used for network flow control, and the network device is used for forwarding and processing received data packets. SDN technology is used to separate the control plane and forwarding plane (also known as the data plane) of network equipment, realize flexible control of network traffic, and accelerate the innovation of network services. Currently, in an SDN scenario, the controller mainly uses Border Gateway Protocol (English: Border Gateway Protocol, BGP) to advertise or withdraw routes to f...
