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. ^ 10 cl, 4 dwg |
