Description: BGP flap damping is a crucial technique in network management that aims to stabilize the routing table in situations of instability, especially during DDoS attacks. This phenomenon occurs when there are frequent changes in network routes, which can lead to oscillations in the routing table and, consequently, poor network performance. Damping acts as a control mechanism that limits the propagation of changes in the routing table, allowing routes to stabilize before new updates are made. This is achieved by implementing policies that penalize unstable routes, preventing them from being used until their reliability is demonstrated. The technique is particularly relevant in the context of BGP (Border Gateway Protocol), which is the routing protocol used to exchange routing information between autonomous systems on the Internet. By applying damping, network resilience is improved, router load is reduced, and service interruptions are minimized, which is essential for maintaining the availability and integrity of communications in networks increasingly threatened by DDoS attacks.
