“…They both allow a LSR to trigger and control the establishment of a LSP between itself and a remote LER, to strictly or loosely specify the route to be taken by the LSP, and to specify queuing and scheduling parameters to be associated with this LSP at every hop. The relative advantages and disadvantages of these two schemes can be found in [18], but manageable traffic engineering and QoS control cannot be realized unless one of these protocols is deployed.…”

This article describes the main features of Multiprotocol Label Switching (MPLS), a standard architecture proposed by the IETF that integrates label swapping forwarding with network layer routing. The role of MPLS in overcoming limitations of overlay models, such as IP over ATM, and of conventional routing in IP networks, is discussed. The main concepts are introduced and the operation of MPLS is explained -classification of packets into Forward Equivalence Classes, label allocation and binding to routes, label distribution, set up of Label Switched Paths and route selection. Finally, support of traffic engineering and Quality of Service mechanisms in MPLS networks is analysed. MPLS -rationale for a new routing and forwarding architectureThe success of the Internet is mainly due to its flexible architecture, built upon IP, the ubiquitous internetworking layer protocol.IP networks offer unparalleled scalability and flexibility for the deployment of value-added services and are becoming increasingly attractive for carrying services with hard and soft real-time constraints. This requires extending the traditional best-effort model, designed from the outset for elastic data traffic, with mechanisms that provide differentiated and predictable Quality of Service (QoS) to a wide variety of applications with different requirements [1]. The Internet Engineering Task Force (IETF) has already specified the Integrated Services (IntServ) [2] and the Differentiated Services (DiffServ) [3] models with these goals in mind. Carriers' requirementsWith the increasing demand and explosive growth of the Internet, service providers require a dependable and controllable network infrastructure that can offer consistent performance. In many cases, the original router-based backbone networks evolved into a two level structure made up of a high speed core network interconnecting edge devices (IP routers) that, in turn, interface with access networks and provide common services to users, such as security, accounting, Virtual Private Networks (VPNs), web hosting, etc.Management of such networks requires powerful traffic engineering techniques, that is, the capability of mapping flows into the physical network topology and evenly distributing traffic over the network links, to achieve an efficient utilization of network resources, avoid congestion and improve network performance.

“…Explicitly routed LSPs can also be referred to as constraint based LSPS (CR-LSPs), which are specified in the setup message. At each hop, a label request is sent to the next hop along the LSP [8].…”

The basic components of a network can be used in its enhancements through the provision of some reliable services. In order to achieve these provisions of reliable services, various technologies have been put in place. One of these technologies is MPLS and it provides Quality of Service and this is done by delivering such services with high transmission speed, low delays and low losses. Due to the ability to implement Traffic Engineering in MPLS, it can be used to efficiently implement real-time applications. Signaling protocols such as RSVP-TE and CR-LDP are used for Traffic Engineering in MPLS.In this paper, the modeling of IP, MPLS and MPLS RSVP-TE (with path reserved for voice traffic) networks are presented and the performance parameters of the networks are compared. OPNET modeler 16.0 is used to simulate all the networks and the comparison is made for parameters such as Voice packet delay variation, Video packet end-to-end delay variation and voice packet reception rate.

The main components of a network are vital to its enhancements by providing reliable services. Different technologies have been put in place to enhance application services in a network. MPLS is one of such technologies and it provides a reliable delivery of application services. It delivers services with low delays, low losses and high speed of transmission. Due to the Traffic Engineering feature of MPLS, it can be used to efficiently utilize network resources as well as implement real-time applications (voice and video). Signalling protocols such as RSVP-TE and CR-LDP are used for Traffic Engineering in MPLS.In this research, the modelling of IP, MPLS and MPLS RSVP-TE (with path reserved for voice traffic) networks are presented and the performance parameters of the networks are compared. OPNET modeler 16.0 is used to simulate all the networks and the comparison is made for parameters such as throughput, utilization and voice jitter.
