TOPOLOGY INFORMATION PROCESSING METHOD AND DEVICE

摘要

Embodiments of the present invention provide a topology information processing method and device. In one aspect of the embodiments of the present invention, a first control device obtains topology information of a first domain to which the first control device belongs, the first domain being a domain formed by the first control device and a network device managed by the first control device; and the first control device receives topology information of a second domain to which a second control device belongs, the topology information being sent by the second control device, and the second domain being a domain formed by the second control device and a network device managed by the second control device, so that the first control device can send topology information comprising the topology information of the first domain to the second control device, which can avoid the problem in the prior art that processing load of a control device increases because the control device needs to collect topology information of the entire network through a network device managed by the control device, thereby reducing the processing load of the control device, and being conducive to expanding the network scale.
