“…MPLS TE operates at an aggregate level across all classes of service and as a result it cannot give bandwidth guarantees on a per class basis. The basic DiffServ aware TE requirement is to be able to make separate bandwidth reservations for different classes of traffic and give different forwarding behaviour based on the class [1]. This implies keeping track of how much bandwidth is available for each type of traffic at any given time on all routers throughout the network.…”

Quality of Service (QoS) in Real Time Applications such as video, voice, online gaming is becoming the major concern. In Today's Scenario Voice over Internet Protocol (VoIP) is an emerging service because of the benefits of this service. The most advantageous benefit which attracts many people using this service is the low cost. QoS is an important factor for the voice traffic. Internet Protocol (IP) network implements QoS in two ways i.e. Integrated Services (IntServ) and Differentiated Services (DiffServ) but still VoIP suffers from delay, voice echo, packets loss or Intermittent silent pauses. Multi Protocol Label Switching (MPLS) is a framework specified by IETF when used with IP increases its QoS. MPLS is used as an extension to IP. In this paper we define the MPLS QoS management and how it supports the IP QoS architecture.

“…Such QoS policies can be handled through the use of traffic engineering [18], [19] and differentiated services [20]. Moreover, several work exists on analyzing the performance of QoS in MPLS deployments with such techniques [21], [22], [23], [24]. Most of these studies acknowledge the success of MPLS in providing better QoS upon service classification.…”

Abstract-We present HADEGA, a novel adaptive mitigation solution to handle the impact of network attacks. By extracting information from network detection alerts, and build upon the Multiprotocol Label Switching (MPLS) standard, the solution assigns labels and quality of service treatments to suspicious flows. As a result, those labeled flows are controlled and properly handled inside the core network of service providers. We conducted simulations in order to evaluate the efficiency of our approach. Results are presented.

“…In addition, because the DS-TE model uses an extension of RSVP, it suffers from the same scalability problem. In an analysis of QoS performance in DS-TE [35] is stated that MPLS TE avoids the scalability issue of IntServ because it maintains state information of collections of flows and not of single micro-flows. However, the scalability problem has as a main reason the fact that state information must be kept in the router, and as long as the same principles are used, the same problem might appear.…”

This paper presents an overview of the current service delivery models that exist in the Internet, covering also the motivation that triggered the introduction of each model separately. Different Quality of Service (QoS) frameworks like Integrated Services (IntServ), Differentiated Services (DiffServ) and Multiprotocol Label Switching (MPLS) are presented taking into consideration also the alteration of each of the mechanisms proposed by the Internet Engineering Task Force (IETF) over time. We illustrate some important characteristics of the existing service delivery models and open issues for Internet QoS, highlighting the need of research on the measurability of the Resource Reservation Protocol (RSVP).
