摘要： A traffic network having a wired as well as a wireless network backbone is managed. The wireless network backbone has relay nodes having wireless routers, some acting as gateways to the wired backbone network and some as relay bridge routers for access network access. A management system has a logical multilevel hierarchical network overlying the traffic network. It is adapted to use the relay nodes as management stations. It performs a grouping process by arranging network nodes, including the relay nodes, in groups, each with a cluster head, on different hierarchical levels. A grouping controller controls the grouping and allocation of cluster heads based on a number of grouping constraints given by one or more criteria to be fulfilled at each hierarchical level. The criteria are calculated based on given metrics, the constraints are modeled, and fulfillment of the constraints is verified at each hierarchical level.

摘要： A non-transitory machine readable medium storing a program that configures managed forwarding elements to establish tunnels between the managed forwarding elements is described. From a particular managed forwarding element, the program receives information regarding coupling of a network element to the first managed forwarding element. Upon receiving the information, the program generates a set of universal flow entries for configuring another managed forwarding element to establish a tunnel to the particular managed forwarding element.

摘要： For a controller for managing a network including managed forwarding elements that forward data in the network, a method for configuring a set of managed forwarding elements is described. The method generates a first set of flow entries for configuring the set of managed forwarding elements to forward packets as non-first-hop forwarding elements for a logical datapath set. The method generates a second set of flow entries for configuring the set of managed forwarding elements to forward packets as first-hop forwarding elements for the logical datapath set. The method sends the first set of flow entries to the set of managed forwarding elements prior to sending the second set of flow entries to the set of managed forwarding elements.

摘要： One embodiment of the present invention provides a computing system. The computing system includes a discovery module, a high-availability management module, and a controlling module. The discovery module determines local switch-specific information associated with a switch based on a discovery response packet. The high-availability management module determines remote switch-specific information about the same switch with respect to a remote computing system. The controlling module determines whether the computing system is to manage the switch based on a metric derived from the local and remote switch-specific information.

摘要： The present invention relates to a pseudonode used for deployment on a peer to peer network which pseudonode comprises an IP address and client ID that is changeable upon the occurrence of a preselected event and includes a list containing at least one searchable data object. The pseudonode is programmed for monitoring the network to receive search requests therefrom and to compare each said received search with said list of data objects and to respond to such request. The invention also provides a method for monitoring search requests for selected objects by nodes on a peer to peer network. The method includes interposing the pseudonodes on the network in which it is configured to provide at least one IP address and optionally at least one client ID. The pseudonode has at least one stored object corresponding to a request object stored at said pseudonode; and monitors the network to detect requests matching at least one of the stored objects and acquires a unique ID generated by any network node requesting the object matching that stored object on the pseudonode and responding to substantially each node representing an acquired ID.
