QoS management network

Quality of service (QoS) refers to the capability of a network to provide better service to selected network traffic over one kind of networks or a heterogeneous network, including IP, ATM, frame relay or SONET. However, the current existing QoS technology is not efficient in such a heterogeneous network environment. In this paper, the QoS management network (QMN) concept is proposed. Its basic idea is that the QoS guarantee should be implemented based on the overall network environment in order to provide regulation and management of network resources. The proposed QMN is vendor neutral, relatively static, and it is flexible to scale from a partial network domain to a larger network domain. It does not replace the current existing QoS technology, rather it acts as traffic control and management center with three unique capabilities to achieve QoS requirements using either SIP or ATM UNI over the heterogeneous network as described in detail in this paper.
