摘要： 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.

摘要： Techniques are disclosed for improved data routing and forwarding by exploiting the increasing number of logical cores in a computing system. In certain embodiments, a network device comprising several network interfaces and logical cores is disclosed. The network device may also include a plurality of processing nodes, wherein each processing node includes instructions for processing network packets and is associated with a logical core. Furthermore, the network device may include control logic configured to receive a network packet at an interface, select a subset of processing nodes from the plurality of processing nodes for processing the network packet, based on contents of the network packet and the interface that the network packet was received at, and schedule processing of the network packet by the subset of the processing nodes on the respective logical cores associated with each of the subset of the processing nodes.
