Explicit routing in MPLS is utilized in traffic engineering to maximize the operational network performance and to provide Quality of Service (QoS). However, difficulties arise while integrating native IP multicasting with MPLS traffic engineering, such as point-to-multipoint or multipoint-to-multipoint LSPs layout design and traffic aggregation. In this paper, we have proposed an edge router m...

This document describes extensions to the Intermediate System to Intermediate System (IS-IS) protocol to support Traffic Engineering (TE). This document extends the IS-IS protocol by specifying new information that an Intermediate System (router) can place in Link State Protocol (LSP) Data Units. This information describes additional details regarding the state of the network that are useful fo...

As IP / MPLS network service providers drive for improved network efficiencies, traffic engineering is becoming increasingly important. In this article we review the approaches for traffic engineering in IP / MPLS networks and present the result of a study, which compares their performance in operational networks.

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract It is highly desired, in several cases, to take into...

OMP Simulation Results in IP Networks Károly Farkas High Speed Networks Laboratory Department of Telecommunications and Telematics Budapest University of Technology and Economics, H-1117, Pázmány P. s. 1/D., Budapest, Hungary E-mail: [email protected] Abstract These days the use of Internet almost everywhere is not surprising. However, the used traffic management solutions in the Net a...

Multi Protocol Label Switching (MPLS) is an innovative and vibrant technology. The most famous applications of MPLS technology are MPLS VPN, MPLT Traffic engineering and MPLS QoS and Any Transport over MPLS (AToM). This study addressed only MPLS Traffic engineering, which is one of the driving factors of deploying MPLS in service provider networks. This research consists of two main sections; i...

This memo defines the Management Information Base (MIB) objects for managing the Traffic Engineering Database (TED) information with extensions in support of the Multiprotocol Label Switching (MPLS) with Traffic Engineering (TE) as well as Generalized MPLS (GMPLS) for use with network management protocols.

This paper presents a new method to perform QoS enabled traffic engineering based mostly on conventional IP routing techniques. By combining the flexibility of layer 3 routing protocols like OSPF with a management plane link weight traffic engineering technique, this paper makes the proposition that more recent technologies such as MPLS are not essential to enable services that require QoS supp...

This thesis focusses on problems related to (i) Inference of Congestion in the Internet and (ii) Multicast Traffic Engineering in Overlay Networks. In the first part of the thesis, we propose methods which help to improve the quality of the congestion inference on both end-to-end paths and internal network links in the Internet. Today, transport protocols which transfer data in the Internet cla...

Several Link-type sub-Type-Length-Values (sub-TLVs) have been defined for Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) in the context of Multiprotocol Label Switching (MPLS) Traffic Engineering (TE), in order to advertise some link characteristics such as the available bandwidth, traffic engineering metric, administrative group, and so on. By making sta...
