Data flow through a network device is periodically sampled. Lower and upper bandwidth reservation limits are periodically updated from the sampled data flow. A current setting of the bandwidth reservation for the flow path associated with the data flow is compared against the range bounded by the lower and upper bandwidth reservation limits. When the current bandwidth reservation falls outside of the range, bandwidth reservation of the flow path is adjusted.

Statistically-driven adaptive bandwidth reservation

Method and system for reducing multicast traffic loss including configuring, on a primary DR including a first configured DR priority, a DR parameter including a value and an attribute; sending to a secondary DR, after a PIM interface comes up, a PIM hello message including a default DR priority lower than a second configured priority of the secondary DR; sending to the secondary DR, after the primary DR reaches a system-up state, a PIM hello message including the default DR priority; performing DR functionality, by the primary DR, after reaching the system-up state; and sending to the secondary DR, after waiting a time period corresponding to the value of the DR parameter, a PIM hello message including the first configured DR priority, where the primary DR waits to send the last PIM hello message to the secondary DR after the time period based on the attribute of the DR parameter.
