What is disclosed is a method of updating a message from a first version to an upgraded version by chaining through intermediate versions, including the steps of receiving an update message having a first version format, and repeatedly generating a revised update message having a next most recent version format based on the update message until a final update message having an upgraded version format is generated. An apparatus for performing the method is also disclosed.

A method and system for a graceful reroute of connections on a link are described. According to one embodiment, in a digital communications network, a method comprises blocking new connections from being established over a link. Old connections are rerouted around the link; and the link is taken out of service.

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.
