A method and apparatus for providing network based load balancing of medical image data among two or more image archive systems is disclosed. A network element is employed to interface to a network carrying medical image data that may include tasks to be performed on the data. A network service associated with the network element monitors the current load or the available capacity of each of the image archive systems. When a task is received the network service determines the level of complexity of the task and compares the level of complexity to the current load or available capacity of each of the image archive systems. The network service selects the one of the image archive systems to perform the task that has the lowest current load or highest available capacity relative to the level of complexity of the received task.

Rather than dropping packets, the invention throttles the rate that audio packets are output from a voice gateway by increasing the VoIP packet size. An encoder in the voice gateway encodes audio signals into audio packets. A processor in the voice gateway then switches the audio packets to the IP network. The invention throttles the rate that these VoIP packets are switched from the voice gateway by varying the number of samples of the incoming audio signals that are encoded into each packet payload. By increasing the packet payload size in the VoIP packets, the voice gateway can switch the same amount of audio data in fewer VoIP packets. Producing fewer VoIP packets increases the available capacity of the voice gateway for processing audio signals for more calls. In other words, encoding more audio data into each VoIP packet keeps the voice gateway from having to drop packets. If capacity in the voice gateway increases (the number of incoming calls decreases), the voice gateway can resume generating VoIP packets at the original packet size.
