Abstract:
1. A voice/data combination system, comprising: a terminal to generate and transmit a real-time data service request message upon a receipt of a request for real-time data service, to generate and transmit a bandwidth request message for the real-time data service upon a receipt of a message indicating that a bandwidth for the real-time data service is unavailable, and to retransmit the real-time data service request message upon a receipt of a bandwidth reservation message; and a switch/router comprising a processor and a traffic manager, the switch/router being configured to check the bandwidth in response to the real-time data service request message, to transmit the message indicating that the bandwidth, when unavailable, is unavailable, to reserve the bandwidth in response to the bandwidth request message received from the terminal, and to transmit the bandwidth reservation message to the terminal if the bandwidth is available, wherein the traffic manager is configured to transmit a bandwidth check response message indicating an availability of the bandwidth to the processor, and wherein the processor is configured to transmit the real-time data service request message if the bandwidth check response message indicates that the bandwidth is available.
