Abstract
This disclosure addresses improving the reliability of network connections between nodes, detection of failures of network connections, and the reduction of control packets exchanged between nodes. A second node may stop sending control packets to a first node causing a reduction in network throughput and increased network capacity. The network connection from the first node to the second may be of a first type and the connection from the second node to the first node may be of a second type. When a failure of the connection of the first type occurs, communication of the failure may be sent in a flag from the second node to the first node using the second type. A response to the flag received at the first node may be sent to the second node. The response may be sent using the second type of network connection because the first type failed.
