摘要： Systems and methods for managing a network are described. A view of current state of the network is maintained where the current state of the network characterizes network topology and network constituents, including network entities and network elements residing in or on the network. Events are announced that correspond to changes in the state of the network and one or more network elements can be configured accordingly. Methods for managing network traffic are described that ensure forwarding and other actions taken by network elements implement globally declared network policy and refer to high-level names, independently of network topology and the location of network constituents. Methods for discovering network constituents are described, whereby are automatically configured. Routing may be performed using ACL and packets can be intercepted to permit host to continue in sleep mode. The methods are applicable to virtual environments.

摘要翻译： 描述用于管理网络的系统和方法。 维持网络当前状态的视图，其中网络的当前状态表征网络拓扑和网络成分，包括驻留在网络中或网络上的网络实体和网络元素。 公布对应于网络状态的变化的事件，并且可以相应地配置一个或多个网络元件。 描述了用于管理网络流量的方法，其确保网元采取的转发和其他动作实现全球声明的网络策略，并且独立于网络拓扑和网络组成部分的位置来参考高级别名称。 描述了用于发现网络组件的方法，由此被自动配置。 可以使用ACL执行路由，并且可以拦截数据包以允许主机在睡眠模式下继续。 这些方法适用于虚拟环境。
