Comparative analysis of path computation techniques for MPLS traffic engineering
Computer Networks, 2002We consider the problem of computing traffic engineered paths for requests having bandwidth and delay requirements, when these requests arrive in the network independent of one another. Providing bandwidth guarantees to applications has been important in networks offering service differentiation.

Minimal feedback optimal algorithms for traffic engineering in computer networks
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004This paper addresses the problem of traffic engineering in computer networks. More precisely, optimal data rate adaptation laws are provided, which are applicable to networks where both multiple paths are available between any pair of source/destination nodes and multiple classes of service are to be provided.

Review of computer software for traffic engineers
Transport Reviews, 1989The mid‐1970s saw the initiation of several lengthy research and development programmes in the United Kingdom which culminated in a range of software for the traffic engineer. The early 1980s brought cheap, powerful microcomputers, thereby enabling the facilities offered by the software to be exploited to the full.

Multiple Path Computation Element (PCE) Cooperation for Multi-layer Traffic Engineering
OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007The inefficiencies that affect current PCE cooperation based on PCE communication protocol (PCEP) in multi-layer networks are presented. A vertical approach is proposed to guarantee effective TE solutions while limiting the amount of exchanged information.

Path Computation for Traffic Engineering in MPLS Networks
2001We consider the problem of computing traffic engineered paths for bandwidth requests, when these requests arrive in the network independent of one another. Reservation of bandwidth along pre-selected paths have become important in networks providing service differentiation and bandwidth guarantees to applications.

Multi-constrained path computation algorithms for Traffic Engineering over Wireless Mesh Networks
2009 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks & Workshops, 2009We propose a Traffic Engineering (TE) architecture to supply Wireless Mesh Networks (WMNs) with an efficient support of diverse applications with different Quality of Service (QoS) requirements. The proposed TE-WMN architecture is based on the MPLS technology.

Path computation element (PCE)-based traffic engineering in MPLS and GMPLS networks
2007 IEEE Sarnoff Symposium, 2007This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based ...

IEEE Network, 2007
The Path Computation Element Working Group at the Internet Engineering Task Force is chartered to specify a PCE-based architecture for the path computation of interdomain MPLS- and GMPLS-based traffic engineered label switched paths. In this architecture, path computation does not occur at the head-end LSR, but on another path computation entity that ...

Agents, Engines, Traffic, Objects and Illusions: Paradigms of Computer Science
Journal of Technical Writing and Communication, 1991It has been shown that the language of some scientific disciplines is highly metaphorical, but there is probably no field that uses metaphor quite as pervasively and idiosyncratically as does computer science. One senses that this phenomenon results from a need to compensate for the exceedingly abstract nature of the discipline.
