“…Their design and implementation was evaluated in an IP QoS testbed. In [7], the authors demonstrated the benefits of traffic engineering. They evaluated traffic engineering in the presence of QoS-based routing schemes compared with the standard destination-based routing.…”

“…Hence, traffic splitting over multiple bandwidth offers is not considered in this paper. Constraint (7) ensures that only one of the bandwidth offers, which are advertised at a border router through different inter-AS links, is selected for each remote destination prefix. This constraint ensures the BGP rule that only one route toward a remote destination prefix is selected as the best route.…”

“…Dynamic alternative routing was widely used in ISDN and has been proposed for optical [10] and MPLS networks in order to improve network performance [11], [12], [13]. Additionally, dynamic alternative routing also improves network survivability because of its ability to reroute traffic in congestion situations [14].…”

MPLS is a core technology for nowadays and future networks, and must meet the needs of real-time applications for which network survivability is critical. Dynamic alternative routing has already been proposed several times to increase MPLS network performance. In this paper, a proposal of a protection scheme to be used with dynamic alternative routing is presented and its performance is evaluated through a simulation study.

“…In our study, we use a three dimensional space that addresses QoS routing with network control [11], [10]. Simply put, these three dimensions can be thought of as comprising of path caching, routing schemes and network control; they are addressed in the QoS routing framework presented in [11].…”

In this paper, we attempt to improve the performance in congested parts (CP) of an asymmetric network using network controls and routing mechanisms. Typically, an asymmetric network is characterized by non-uniform link capacities or uneven traffic load or both. In such a network, certain service classes can experience poor performance in parts of the network, even when the average performance is very close to the expected performance level. We studied a network derived from an actual service provider network with asymmetric concentration of traffic. We have developed two metrics in order to capture the congested part behavior in a network. In order to understand the generality of our conclusions, we used three variations of our network and show that controls like Service class based Multi-link Dynamic Capacity Reservation (SMDCR) with a properly chosen reservation factor, significantly reduce variability in the performance over all parts of the network.
