ADVERTISING NETWORK RESOURCE SHARING STATUS IN SDN

摘要

A method is implemented by a network device acting as a switch in a data plane of a software defined net-working (SDN) network. The switch is communicatively coupled to a controller in a control plane of the SDN network, where the controller manages packet processing functionality of the switch. The method to provide data storage resource sharing information to the controller so that the controller can manage data storage resource utilization of the switch. The method includes determining which tables stored in the switch share a data storage resource of the switch and transmitting data storage resource sharing information to the controller, where the data storage resource sharing information includes an indication of the tables that share the data storage resource.
