  • Dynamic control processes and systems for asynchronous transfer mode networks
    Patent number: 5953338
    Abstract: A system comprises a system control module and a plurality of interconnected asynchronous transfer mode switches the interconnected asynchronous transfer mode switches are interconnected with one another via at least one physical interface to form a network. The network is used to transfer various types of information. Each asynchronous transfer mode switch has a connection admission control module to determine whether a virtual connection, such a virtual path, virtual channel, or grouping of virtual paths, can be connected through that particular asynchronous transfer mode switch. The virtual connection is formed from one asynchronous transfer mode switch to at least one other asynchronous transfer mode switch via a link of the at least one physical interface. The system control module connects to at least one asynchronous transfer mode switch and determines whether the virtual connection can be created in the network.
