Abstract
A connection control interface for switches in a network is provided. The connection control interface allows the multiservice switch to provide a number of switch resource partitions to a number of independent controllers coupled to the switch. The switch resource partitions comprise a number of subsets of switch resources that define a number of independent subset networks of a physical network. The connection control interface allows the independent controllers to control the connections of the switch using the number of switch resource partitions. The independent controllers each use one of a number of control systems, the control systems comprising a network software level. The independent controllers comprise a virtual switch interface having a master component and a slave component where the master and slave components may be hosted on different processors. The slave components may be hosted on a control card that controls a number of port cards of the switch or on a port card processor. The switch and the independent controllers are resynchronized when discrepancies are detected between the connections on the switch and those expected by the each of the plurality of independent controllers.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
