“…Therefore, LSPs accommodated with the VTF policy are more likely transmitted on paths containing more than one OLSP. It has been demonstrated that the PTF policy achieves a lower blocking probability, compared to the VTF policy [2]. In addition, the installation of more direct OLSPs avoids the possible bottleneck caused by electronic switching at intermediate routers and consequently PTF improves the end-to-end packet delay and packet loss.…”

“…The first scheme is called RP-Diff and it is based on the RPD technique. The introduction of this technique is motivated by the fact that the choice of the MTE routing policy impacts the offered QoS as well as the resource utilization [2,11]. As a consequence, the service differentiation in a multiservice infrastructure can be improved by deciding the routing policy according to the traffic requirements.…”

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

En las redes de transporte de conmutación automática (ASTN), los servicios pueden configurarse, modificarse y liberarse bajo demanda utilizando diversos mecanismos en el plano de control. En la actualidad, este nuevo paradigma de aprovisionamiento se está estandarizando bajo las bondades de las redes ópticas con conmutación automática (ASON) y la conmutación generalizada por etiquetas multiprotocolo (GMPLS). Este artículo ofrece una visión general de los marcos de ASON y GMPLS en la etapa actual de su desarrollo, revisando primero sus antecedentes y luego analizando las funciones particulares de los métodos de enrutamiento y señalización de cada uno de ellos en la red, incluyendo los modelos de características de red y la arquitectura del plano de control que cada uno propone. Al finalizar se presenta un marco de comparación de los conceptos, revisando las semejanzas y diferencias de los dos recursos y presentando el alcance actual de las redes soportadas bajo una amalgama de arquitecturas GMPLS/ASON, como respuesta a los requerimientos actuales de transmisión de información y confiabilidad a nivel backbone.

The paper addresses the problem of unwanted stabilization of a virtual topology in a dynamic multilayer network using the Packet-Packet-Lambda (PPL) routing strategy. The PPL strategy was already proposed in several papers and is perceived as a valuable solution to the multilayer traffic routing problem in a network with lightpaths created on demand. However, as it is shown, usage of the strategy may bring catastrophic results, since this strategy may create in some point of time an inefficient, extremely stable and long lasting logical topology, which results in a highly penalized network performance. Therefore, enhancements to the strategy are necessary. We show some directions for such improvements.
