A framework for context-driven end-to-end QoS control in Converged Networks

Abstract: Abstract-This paper presents a framework for context-driven policy-based QoS control and end-to-end resource management in converged next generation networks. The Converged Networks QoS Framework (CNQF) is being developed within the IU-ATC project, and comprises distributed functional entities whose instances co-ordinate the converged network infrastructure to facilitate scalable and efficient end-to-end QoS management. The CNQF design leverages aspects of TISPAN, IETF and 3GPP policy-based management architec… Show more

“…Our previous work presented the proposed CNQF architecture, detailing the subsystems, elements, and their interaction whilst also exemplifying some use case scenarios for context-driven QoS control [6]. In this paper we present the implementation of CNQF in Java, validating key elements functionality within a policy-driven QoS control scenario.…”

“…To this end, we have proposed a policy-based network management framework for converged networks end-to-end QoS control and resource management, CNQF (Converged Networks QoS Framework) [3]. CNQF is designed to provide homogeneous, unified, end-to-end QoS management over heterogeneous access technologies, together with scalable, context-aware adaptive QoS control using policy-based paradigms aligned with IETF, TISPAN and 3GPP policy architectures.…”

“…CNQF consists of distributed Policy Decision Points (PDPs) which are responsible for various management and control decisions driven by high-level declarative policies and enforced at policy enforcement points (PEPs) such as routers, switches, and gateways in the converged network transport plane. Our previous work in [3], presented CNQF framework architecture and exemplified use case scenarios for contextdriven QoS adaptation. This paper focuses on measurementbased evaluation of policy-driven QoS management based on CNQF architecture with real traffic flows on a testbed where a Java based prototype of the CNQF Resource Management Subsystem is deployed.…”

“…Within our project, we leverage a policy-based management paradigm to develop a context-aware policy-based framework for QoS control and resource management in converged next generation networks. The policy-based framework, Converged Networks QoS Framework (CNQF), is designed to provide homogeneous, unified, end-to-end QoS support over heteroge neous access technologies, together with scalable, context aware resource control and adaptive QoS control [5]. CNQF will benefit operators through providing critical policy control and adaptation functionality needed to deliver a wide variety of high-value services with guaranteed QoS across fixed and wireless access technologies.…”
