ABSTRACT: Currently, a straightforward way to design BGP-based Traffic Engineering (TE) tools for stub Autonomous Systems (AS) is to
rely on selfish routing mechanisms. Although TE tools can find an optimal solution, this optimum represents only a local optimum
for outbound traffic. Indeed, this is one of the main limitations of the selfish routing approach. This approach makes the
TE tools unaware of the effects of their route choices on transit AS throughout the chosen paths, due to uncoordinated routing
decisions, and congestion can occur on distant intra- or inter-domain links. Thus, cooperation among AS is the key to avoid
the performance degradation and routing instability caused by the selfish routing approach and it would be fundamental for
the future QoS-aware Internet. With these objectives in mind this paper presents and discusses a framework for coordinated
Inter-domain QoS Routing (QoSR) decisions among stub and downstream AS taking into account multiple traffic QoS constraints
and routing preferences. The paper includes a description of the main mechanisms and algorithms that integrate the framework,
and finally a discussion of the implementation issues.

ABSTRACT: Quality of Service Routing is at present an active and remarkable research area, since most emerging network services require specialized Quality of Service (QoS) functionalities that cannot be provided by the current QoS-unaware routing protocols. The provisioning of QoS based network services is in general terms an extremely complex problem, and a significant part of this complexity lies in the routing layer. Indeed, the problem of QoS Routing with multiple additive constraints is known to be NP-hard. Thus, a successful and wide deployment of the most novel network services demands that we thoroughly understand the essence of QoS Routing dynamics, and also that the proposed solutions to this complex problem should be indeed feasible and affordable. This article surveys the most important open issues in terms of QoS Routing, and also briefly presents some of the most compelling proposals and ongoing research efforts done both inside and outside the E-Next Community to address some of those issues Postprint (published version)

ABSTRACT: This paper proposes a novel and incremental approach to Inter-Domain QoS Routing. Our approach is to provide a completely
distributed Overlay Architecture and a routing layer for dynamic QoS provisioning, and to use QoS extensions and Traffic Engineering
capabilities of the underlying BGP layer for static QoS provisioning. Our focus is mainly on influencing how traffic is exchanged
among non-directly connected multi-homed Autonomous Systems based on specific QoS parameters. We provide evidence supporting
the feasibility of our approach by means of simulation.

ABSTRACT: At present, service providers have several incentives to extend the reach of long-lived MPLS paths across domains. Providers, however, will face a number of trade-offs while choosing the optimal set of MPLS paths to be established. In this paper, we focus on the multi-objective decision problem of maximizing the traffic demands to be covered by long-lived MPLS paths from a source domain S to its major destination domains, while minimizing the monetary costs incurred. The problem is formulated subject to a budget constraint, which assures the minimum expected revenue for the provider in S. A major advantage of the analysis and solution proposed in this paper is that it can be easily generalized, and applied in other settings where constrained problems considering maximum coverage vs. cost are critical.
