NETWORK TOPOLOGY DISCOVERY IN A FRAME RELAY BASED WIDE AREA NETWORK COMPRISING MULTIPLE LOCAL AREA NETWORKS
First Claim
1. An apparatus for mapping a connection between a destination local area network (LAN) and a local LAN where said LANs are coupled by a frame relay wide area network (WAN), the apparatus comprising:
- means for identifying a local network address for each frame relay interface in the local LAN;
means for obtaining the destination data link connection identifier (DLCI) associated with each local network address;
means for deriving the destination network address associated with each destination DLCI; and
means for obtaining the local DLCI associated with each destination network address.

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.
