QoSJava: An End-to-End QoS Solution

Incompatibility of different QoS (Quality of Service) mechanisms and heterogeneity of different vendors’ network devices are the major obstacles for providing end-to-end QoS in IP network. Inspired by Java, we propose an end-to-end QoS solution in this paper, i.e. QoSJava, which decouples QoS requirements from network details. By QoS Mechanisms Adapter and Device Driver, which act as “Java Virtual Machine”, QoSJava enables interoperation between different QoS mechanisms and cooperation of dissimilar network devices. A prototype of QoSJava has been implemented, and the experimental results prove that network devices can be configured automatically to provide an end-to-end QoS. Moreover, QoSJava is not only compatible with current QoS mechanisms and devices, but open to new QoS solutions and advanced devices in the future.
