Distributed network management system and method
A distributed network management system and method of operation. The system includes at least one hub server and at least one remote server, where the hub server and the remote server communicate with each other. The remote server additionally communicates with and monitors one or more network devices. In the event that the remote server becomes inoperational, the hub server assumes monitoring of the network device. For redundancy, primary and secondary hub servers can be provided, wherein the primary and secondary hub servers communicate with each other and are capable of communicating with the remote server. For further redundancy, primary and secondary remote servers can be provided, wherein the primary and secondary remote servers communicate with each other but independently monitor the network devices. In the peered remote configuration, the hub server is capable of communicating with either of the remote servers. Where both the hub servers and the remote servers are peered, each hub server is capable of communicating with each remote server.

Methods and systems for providing dynamic domain name system for inbound route control
The present invention relates to methods and systems for providing dynamic domain name system (DNS) for inbound route control. For instance, the present invention provides a method that considers load data for each of the network locations that provide an application, such online content or a web site available at multiple geographically distinct data centers, as well as performance data for paths through the various network service providers that serve the locations where the application is available. The IP address that is delivered by the DNS is dynamically controlled to select which IP address, i.e., provider, provides the best path.

System and method for end to end route control
Session independent end to end route control is provided by coordination between a pair of route control devices. Each device determines whether received traffic qualifies for end to end route control and whether the device at the other end supports end to end route control. If so, then the route control devices determine a routing mode, such as tunneling or address translation, and routing parameters. The performance of the selected path is monitored and is changed if the performance becomes unacceptable. Path performance can be measured using one-way measurement techniques that use a common inbound path or a control channel.
