Buffer budgeting
Buffer budgeting allocates and manages buffer resources in network devices to optimize packet handling, prevent congestion, and ensure reliable performance.
Buffer budgeting determines the right amount of buffer space for different traffic types, considering traffic patterns, link speeds, and QoS requirements. Techniques include partitioning buffers among queues, using Active Queue Management (AQM) like RED or CoDel, and dynamically adjusting allocations based on network conditions.
Effective buffer budgeting improves performance, guarantees QoS for critical traffic, and prevents congestion or packet loss. It requires ongoing monitoring and adaptation as network demands evolve.
Alternatives or complements include traffic shaping, congestion avoidance algorithms, or hardware upgrades for additional buffer capacity.
