Hierarchical network configuration
Systems, methods, apparatus and computer-readable medium are described for improving efficiency and robustness for configuring data-planes. Furthermore, systems, methods, and devices are provided for efficiently storing, maintaining and retrieving configuration information for data-planes. The configuration information may be stored and retrieved from a hierarchy of information stored in memory, such as a hierarchy of information in memory, wherein the hierarchy of information has configuration data for one or more data-planes and represents one or more command sequences issued by a controller of the control-plane to one or more data-planes. In certain implementations, the hierarchy of information comprises a plurality of nodes, wherein each node represents at least a portion of a command sequence issued by the controller. The command sequences may be configuration command sequences issued by the control plane to configure the data-planes.
