MPLS: Managing the New Internet
2000
Traffic requirements on the Internet have changed from reliability to timeliness of delivery as different types of applications are being deployed on it. This situation has prompted the industry and IETF (Internet Engineering Task Force) to develop new protocols and techniques to meet the challenges. One of the important protocols developed is MPLS (Multi Protocol Label Switching) that allows network
A Review: Multi Protocol Label Switching (Mpls)
2014
The demand for technology called MPLS is increasing day by day in most internet service provider networks. Majority of the carriers are deploying MPLS in their backbone networks to facilitate a number of services and applications such as virtual private networks, quality of service (QoS) and traffic engineering. MPLS is a scalable, protocol-independent protocol. MPLS allows for creating end-to-end circuits across any type of transport medium using any protocol. The primary benefit of MPLS is to eliminate the dependence on a particular OSI model data-link layer technology such as asynchronous transfer mode (ATM), Frame Relay or Ethernet and eliminates the need for multiple layer-2 networks to satisfy different types of traffic. This paper reflects a detailed overview on MPLS with its architectural terminology, working and the services that it offers.
Performance Comparison of MPLS TE Networks with Traditional Networks
2018
The tremendous growth and requirements for service quality, tenability, and efficiency have made traffic engineering an essential consideration in the design and operation of large public Internet backbone networks. Traffic engineering is the aspect of Internet network engineering that deals with the problem of operation analysis and operation optimization of functional IP networks. The principal target of internet traffic engineering is to direct the packets of IP traffic through a given system in an efficient and speedy manner conceivable. This paper explores the role of signaling protocols for traffic engineering in MPLS and provides a comparative analysis of non-MPLS and MPLS networks for substantial traffic situations. The simulation of the proposed solution has been performed in OPNET environment and the simulation results prove enhanced network performance of MPLS.
Multi-layer architecture for realization of network virtualization using MPLS technology
ICT express, 2017
Network virtualization (NV) increases Internet flexibility by separating policies from mechanisms. This makes developing new applications, managing the Internet, and supporting different applications much easier. In this study, we introduce a multi-layer architecture which combines multi-level multiprotocol label switching (MPLS) technology with NV. The proposed architecture combines the high speed advantage of MPLS with the high flexibility of NV. We use MPLS in MPLS technique and encapsulate each MPLS packet within another when it encounters a new virtual network. Our architecture has the potential to improve Internet flexibility and pave the way for deployment and commercialization of NV in next generation networks. c
