Abstract: A method and apparatus for managing networks across multiple domains are disclosed. For example, the method stores a mapping table that correlates one or more Customer Edge Routers (CERs) with one or more Route Processing Modules (RPMs) in at least one seed-file distributor, where each of the one or more Customer Edge Routers (CERs) is monitored by one of the at least one availability manager. The method receives an alarm associated with one of the one or more RPMs that affects one of the one or more CERs, where the alarm is received by one of the at least one availability manager that is monitoring the affected one of the one or more CERs. The method then provides a status associated with the one of said one or more RPMs in accordance with the alarm.

Abstract: A destination local area network (LAN) and a local LAN are coupled by an ATM-based wide area network (WAN). Each LAN includes a router. The WAN includes at least two ATM switches having switch ports. In order to identify and map a connection between the destination LAN and the local LAN, an end-to-end LAN-WAN-LAN connection components template is created. The template contains a number of fields which are populated during the course of identifying the connection. The connection is identified by using IP addresses, subnet masks and virtual circuit identifier values of ATM interfaces on the routers. Virtual circuit identifier values associated with pairs of IP addresses in the connection are identified, and associated with identifier values from the ATM interfaces on the routers. The associated configuration information and components of the WAN are retrieved and stored alongside entries in the list.

Abstract: A destination local area network (LAN) and a local LAN are coupled by an FR-ATM Service Interworking (SIW)-based wide area network (WAN). In order to identify a connection between the destination LAN and the local LAN, an end-to-end LAN-WAN-LAN connection components template is created, which contains a number of fields which are populated during the course of identifying the connection. FR and ATM interfaces are identified on each router. The network addresses conform to Internet Protocol (IP) and are part of the same subnet. The IP address, IP subnet mask, city, state, DLCI value retrieved from the FR interface, and the VPI/VCI values retrieved from the ATM interface are stored to create a list describing the physical and logical characteristics of the FR and ATM interfaces. A pair of network addresses is identified using the IP address in conjunction with the subnet mask stored on either the FR or ATM interface in the list. The DLCI value associated with each of the network IP addresses is identified.

Abstract: A method, apparatus, and computer program product for mapping a connection between a destination local area network (LAN) and a local LAN where the LANs are coupled by a frame relay wide area network (WAN). The method includes the steps of identifying a local network address for each frame relay interface in the local LAN; obtaining the destination data link connection identifier (DLCI) associated with each local network address; deriving the destination network address associated with each destination interface; and obtaining the local DLCI associated with each destination network address. The method can also include the step of deriving WAN switch ports associated with the connection using the local and destination DLCIs.
