Service differentiation in IP/MPLS over ASON/GMPLS networks

There is a general agreement that the future infrastructure for broadband communications will consist of Automatically Switched Optical Networks (ASONs) controlled by the Generalized Multi-Protocol Label Switching (GMPLS) control plane. Due to the convergence of most services on the Internet Protocol (IP) layer, ASON/GMPLS networks need to provide transport for a variety of applications having different Quality of Service (QoS) requirements. This implies that the Differentiated Service paradigm, which improves the QoS in pure IP networks, needs to be extended to the new underlying infrastructure. This article proposes and compares three schemes for the service differentiation in IP/MPLS over ASON/GMPLS networks. Simulation results demonstrate that a fair trade-off between QoS and resource utilization is achieved when combining routing policy differentiation (RPD), virtual topology differentiation (VTD), and virtual topology sharing (VTS) techniques. The RPD technique decides on the multilayer routing policy to apply depending on the Class of Service (CoS). The VTD technique transports different CoS over different independent virtual topologies. The VTS technique introduces a certain degree of resource sharing among the different virtual topologies

“…The multiservice capability allows networks to support various traffic types with different requirements in terms of QoS. The self-adaptive nature is necessary to replace the traditional overprovisioning, which for Internet traffic seems not to be as profitable as it is for voice services [1] and [4].…”

Due to the unpredictability of IP traffic, MANs are migrating from SONET/SDH ring architectures to DWDM mesh infrastructures. Firstly, the fast advance in optical technologies has provided DWDM networks with extremely high bandwidth capability (i.e. . Secondly, Generalized Multi Protocol Label Switching (GMPLS) and Multilayer Traffic Engineering (MTE) paradigms have turned them into highly flexible, scalable and cost efficient infrastructures able to improve service provider's return on investment (ROI). With the GMPLS automated control plane, IP/DWDM networks can take advantage of a better integration between the electrical and optical domains and consequently of a more optimized resource usage. GMPLS enables network-state-depended dynamic routing and grooming and provides network operators with the tools to differentiate service types and increase the offered QoS. This paper discusses the benefits of GMPLS as an integrator paradigm in IP/DWDM metro infrastructures and proposes a QoS control framework which allows a network operator to accommodate MPLS/DiffServ traffic on different virtual topologies that can guarantee different QoS levels. The benefits of GMPLS/MTE and of the proposed scheme are discussed by means of simulation results.

With the drastic increasing of data traffic, the optical transport network will be adjusted to be services-oriented networks. Its traffic engineering system should be able to dynamically react to traffic changes while at the same time fulfilling QoS requirements for different classes of service. So the next generation optical network will handle priority, preemption mechanisms, and traffic rerouting in order to concurrently accommodate the largest amount of traffic. At the same time, transport networks need to evolve so as to drastically reduce both deployment costs and operating expenses.One of a reasonable strategy to achieve the goals is to simplify the network architecture by reducing the number of layers.GMPLS protocols enable the coordination between the IP and the optical layers and provide classified services. The collaboration of both layers in the routing process leads to optimization of network performance. Simulation results show the network performance for different priority strategies on resource allocation.
