SCHEME FOR ENSURING FAULT TOLERANCE IN COMMUNICATION NETWORKS Russian patent published in 2011 - IPC H04L12/24

Abstract RU 2424625 C2

FIELD: information technology.

SUBSTANCE: connection-oriented network 10 has multiple nodes, including multiple boundary nodes 12, 14, 16, 18. The network can detect a primary tunnel connecting one of primary boundary nodes 12, 14 with another boundary node 14, 12, and a secondary tunnel connecting one of secondary boundary nodes 16, 18 with another boundary node 12, 14, 16, 18. The network can redirect traffic from the primary tunnel to the secondary tunnel if failure is detected in the primary tunnel.

EFFECT: high degree of failure tolerance.
