A method, a device, and a storage medium provide for receiving packets; determining a traffic flow rate value pertaining to the packets; comparing the traffic flow rate value to a flow rate threshold value; selecting one or more candidate paths that are not bandwidth-aware; calculating a current available bandwidth for each of the one or more candidate paths; selecting one or more of the one or more candidate paths based on the traffic flow rate value and the current available bandwidth; and transmitting the packets to a destination via the one or more of the one or more candidate paths.

Label switching or equivalent network multipath traffic control

A network device determines that an outgoing network-to-network interface has dropped one or more network control packets and incrementally adjusts, based on the determining, a drop threshold parameter for the network control packets to give preference to the network control packets over non-network control packets. After the adjusting, the network device monitors traffic over the interface, and preempts, based on the monitoring, a low-priority label switched path (LSP) using the interface when the interface reaches a congested threshold or when the interface has dropped one or more other network control packets. The network device restores the low-priority LSP to the interface when the interface has reached an uncongested threshold.

Network stabilizer

A device may include a control module and a line card. The control module may be configured to run a routing protocol to obtain routing information from network devices. The line card may include a processor. The processor may be configured to establish a bidirectional forwarding detection (BFD) session with a remote device, determine whether an interface associated with the BFD session is flapping, terminate the BFD session when the interface is flapping, disable the interface when the interface is flapping, re-enable the interface after a dampening recovery period elapses, reestablish the BFD session, and send a BFD packet to the remote device.
