Group based allocation of network bandwidth

The present invention extends to methods, systems, and computer program products for group based allocation of terminal server network bandwidth. Output packets are classified into groups based on classification criteria. Output packets for each group are queue into a corresponding queue. During a queue flush cycle each queue containing data is flushed for an essentially equal amount of time. Flushing each queue essentially equally reduces the negative impact that can otherwise result when a subset of sessions (or even a single session) request(s) a disproportional share of terminal server network bandwidth. Responsiveness can be further increased by distributing the essentially equal amount for each queue across the queue flush cycle.
