    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： In general, the present invention relates to a virtual platform in which one or more distributed virtual switches can be created for use in virtual networking. According to some aspects, the distributed virtual switch according to the invention provides the ability for virtual and physical machines to more readily, securely, and efficiently communicate with each other even if they are not located on the same physical host and/or in the same subnet or VLAN. According other aspects, the distributed virtual switches of the invention can support integration with traditional IP networks and support sophisticated IP technologies including NAT functionality, stateful firewalling, and notifying the IP network of workload migration. According to further aspects, the virtual platform of the invention creates one or more distributed virtual switches which may be allocated to a tenant, application, or other entity requiring isolation and/or independent configuration state. According to still further aspects, the virtual platform of the invention manages and/or uses VLAN or tunnels (e.g, GRE) to create a distributed virtual switch for a network while working with existing switches and routers in the network. The present invention finds utility in both enterprise networks, datacenters and other facilities.
