Abstract: A cloud network, a measurement system for the cloud network, and a method, a device and a storage medium. For a cloud network, by means of automatically perceiving a measurement intent of a tenant in the cloud network, generating a measurement rule that complies with the measurement intent, and delivering, on the basis of the measurement rule and by means of bypass packet injection, a measurement request message into network element devices on a path to be measured, a network quality analysis is performed with the help of measurement record information generated when the measurement request message passes through different network element devices.

Abstract: A method and an apparatus of generating rule tables for a virtual dedicated network, and a routing method are disclosed. The method includes determining virtual switches which act as switching nodes in a virtual dedicated network based on topological structure information of the virtual dedicated network; and using network identifiers of the virtual switches as keywords to configure and generate rule tables of the virtual dedicated network, the rule tables including at least the keywords which act as addresses of the switching nodes in the rule tables. The embodiments of the present disclosure can greatly reduce the number of table items in a rule table in a virtual dedicated network, and reduce the number of table items of transfer nodes and an amount of data of management and control nodes, thus effectively improving the system performance.
