A method and apparatus for handling data packets transmitted via a communication tunnel are provided. Tunnel parameters corresponding to transmission of data packets via the communication tunnel are monitored, and aggregation parameters are adjusted based on the tunnel parameters. Based on the current aggregation parameters, the data packets can be aggregated into aggregate data packets for transmission via the communication tunnel. The aggregation parameters can be an aggregation window size. The tunnel parameters can be: end-to-end packet delay of the communication tunnel; throughput of the communication tunnel; and status of one or more queues, such as queue size, belonging to routers of the communication tunnel.
