The effects of qos level degradation cost on provider selection and task allocation model in telecommunication networks

, 2010
Firms acquire network capacity from multiple suppliers which offer different Quality of Service (QoS) levels. After acquisition, day-to-day operations such as video conferencing, voice over IP and data applications are allocated between these acquired capacities by considering QoS requirement of each operation.
