摘要： Methods are disclosed for establishing a path for data transmissions in a system having a plurality of possible paths by creating a configuration database and establishing internal connection paths based upon a configuration policy and the configuration database. The configuration policy can be based on available system resources and needs at a given time. In one embodiment, one or more tables are initiated in the configuration database to provide connection information to the system. For example, a path table and a service endpoint table can be employed to establishing a partial record in the configuration database whenever a user connects to a particular port on a universal port card in the system. The method can further include periodically polling records in the path table and transmitting data from the partial records to a policy provisioning manager (PPM). The PPM then implements a connection policy by comparing one or more of the new path characteristics, to the available forwarding card resources in the quadrant containing the universal port card port and path. The path characteristics can include the protocol, the desired number of time slots, the desired number of virtual circuits, and any virtual circuit scheduling restrictions. The PPM can also take other factors into consideration, including quality of service, for example, redundancy requirements or dedicated resource requirements, and balancing resource usage (i.e., load balancing) evenly within a quadrant.

摘要： The present invention provides methods and apparatus for decoupling functional processes, such as network protocol applications and device drivers, from hardware resources through the use of logical resources. Logical resources are created to represent the hardware resources within a computer system and a map is created which associates each logical resource with each hardware resource. Functional processes are associated with the logical resources instead of with the hardware resources such that a functional process may be moved to a different hardware resource simply by changing the map to associate the logical resource associated with the functional process with a different hardware resource.

摘要： The present invention provides a method for upgrading embedded configuration databases while a network device is operating and with minimal disruption to network device operation. While a network device is operating and using an embedded primary configuration database, an embedded backup configuration database stops performing as a backup database and is upgraded. The upgraded configuration database is then switched over to become the primary configuration database. The original primary configuration database may immediately become the backup configuration database, or the original primary configuration database may remain unchanged until the upgrade is committed. If the upgrade is not committed, for example, due to errors, then the original primary configuration database may be quickly switched over to again become the primary configuration database. As a result, embedded configuration databases may be upgraded while a network device is operating and with minimal disruption to network device operation.
