A communication device according to the present invention enhances transfer of time-critical data between one or more LANs and a device (e.g., edge router, etc.) coupled to a backbone network. A virtual bottleneck in the form of a queue is introduced by the communication device at the customer premises or customer end of a backbone network access line where the network congestion or bottleneck resides. The virtual bottleneck delays and / or discards time insensitive traffic prior to time-critical or voice traffic being delayed in the edge router. This is accomplished by the virtual bottleneck queue including a storage capacity or length less than that of a queue utilized by the edge router. A traffic manager or scheduler controlling the virtual bottleneck dynamically adjusts the virtual bottleneck based on the bandwidth required for time-critical packets to ensure sufficient bandwidth is available for those packets.
