摘要： Method and apparatus for determining an enforceable policy applicable to one or more network devices. The method includes attaching one or more rule elements to one or more domain elements to create policies, the domain elements representing network devices and groups of network devices, and the rule elements defining actions, a method for determining whether a conflict exists between the polices, and a method for resolving the conflicts to produce one or more enforceable policies.

摘要： According to an embodiment of the present invention, a method is provided for partitioning a network, comprising modeling the network as a graph comprising nodes which represent network devices, and edges which represent links between the devices, and automatically partitioning the graph into domains. One embodiment of the method includes identifying a number of anchor nodes in the graph and partitioning the domains around the anchor nodes such that each domain contains only one anchor node. Another embodiment of the method includes partitioning a graph without anchor nodes into a number of domains, and assigning controllers to each of the domains. Preferably, the method further includes assigning a weight to each node in the graph, and balancing the partitions as a function of the weight of each node in a respective partition.
摘要翻译：根据本发明的实施例，提供了一种用于划分网络的方法，包括将网络建模为包括表示网络设备的节点的图，以及表示设备之间的链路的边缘，以及将该图自动划分为域。该方法的一个实施例包括识别图中的多个锚节点并且分割锚节点周围的域，使得每个域仅包含一个锚节点。该方法的另一实施例包括将没有锚节点的图划分成多个域，并将控制器分配给每个域。优选地，该方法还包括向图中的每个节点分配权重，以及根据相应分区中的每个节点的权重来平衡分区。
