Abstract

A technique for managing a network by sharing information between distributed network managers which manage a different portion of a large network is disclosed. By sharing such network information, the network management performed by the distributed network managers can inform site managers not only local network conditions but also about network conditions on other remote networks. A filtering operation is used to determine that portion of the network information deemed important to forward to another network manager. A database synchronization operation is also optionally provided so that databases of each network manager, which store topology information concerning the particular portion of the network, can be automatically synchronized.
