Overview The key information maintained by the control plane is the network state. The control plane must aggregate this information and make it available to the application. In addition, in order to maintain scalability and component reuse, applications should be exempt from protocol details, even though network state information is obtained through a specific protocol. The Onos topology of the protocol is implemented by two complementary mechanisms: Network Discovery and configuration. The former uses the network protocol to let Onos identify the location and/or performance of the network elements, and take the initiative to carry out the relevant collection work when the function is enabled. The latter allows applications and operations ...
