Field trial of end-to-end QoS control based on RACS

Quality of service (QoS) control is a challenge to today´s telecommunication world. Guangdong Telecom has been conducting a field trial to demonstrate end-to-end QoS control, which is based on resource and admission control subsystem (RACS) standardized by ETSI. From the results of the field trial, we have confirmed that RACS architecture and the corresponding end-to-end QoS control trial solution will be of great benefit to operator´s next generation network (NGN). The solution adds a service aware, policy based QoS control layer to NGN. It can assist network operators to recapture the missing role in the telecommunication value chain, give necessary QoS support for new services, and grow revenue as a value added service itself
