The techniques utilize existing hardware and BFD software infrastructure. An example network device includes a memory, programmable processor(s), and a control unit configured to execute a timer, receive one or more packets provided by the BFD protocol, detect, based on the received one or more packets, a congestion condition associated with a link via which the network device is coupled to a network, adjust, based on the detected congestion condition, a session detection time defined by the timer, and in response to a failure to receive a packet provided by the BFD protocol within the session detection time defined by the timer, detect a failure associated with the link."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamically adjusting liveliness detection intervals for periodic network communications","description":"In general, techniques are described to dynamically adjust a session detection time defined by a timer in accordance with a bidirectional forwarding detection (BFD) protocol.
