Abstract
This invention provides for a system and method for upgrading an ATM network to a new release of a vendor's ATM platform, or for converting an ATM network to a different vendor's ATM platform, preferably without experiencing any service disruptions. The system and method upgrade involves first reorganizing an existing redundant-based ATM network by splitting the links, for example, fiber links, within the existing redundant-based ATM network among two parallel networks, Network A and Network B. Network A can be changed at this stage. Then the circuits from Network B are moved to Network A by using Bridge and Roll techniques. This hitless procedure allows for the migration of the customer traffic from Network B to Network A without customer traffic disruptions.
