Cariden often presents at conferences (see the news/events page for a recent overview). On this page we provide a selection of talks and papers by Cariden and its customers:
Event: NANOG 33, February 2005, Las Vegas
Author(s): Martin Horneffer, T-Com
Much has been said about traffic engineering with explicit routing vs. tuning of IGP metrics. After a thorough analysis of alternatives, including a full mesh of static and/or dynamic RSVP-based tunnels, T-Com (AS3320) has decided to use the IGP metric-based approach of traffic engineering for its global IP/MPLS-based network. We show how we get the traffic matrix with a home-grown algorithm based on MPLS counters or “LDP statistics,” thus avoiding the need for a full mesh of tunnels just to do the measurements. We also show how we represent the real network in a suitable way for simulation and optimization tools. Last but not least, we discuss some general design issues concerning the IGP metric design. General requirements for IGP metrics in the context of traffic engineering might easily contradict requirements for iBGP route reflection (see “BGP Persistent Route Oscillation Condition,” RFC3345.)

Most recent discussions of Traffic Engineering have centered on protocol enhancements for MPLS TE. In practice, however, TE is tightly bound with network topology and operational considerations. In this tutorial, we provide a practical overview of traditional pre-MPLS TE practices, MPLS options, and new computer-aided approaches.

Event: RIPE 48, May 2004, Amsterdam
Author(s): John Evans (Cisco), Alan Gous (Cariden)
MPLS traffic engineering (TE) is often considered as synonymous with making more efficient use of network bandwidth and/or improving network availability via the capabilities of TE Fast Re-route (FRR). This session considers the theory behind traffic engineering in general, together with the benefits, limitations, and deployment considerations of MPLS TE in the context of IP traffic engineering and engineering core network availability. Consideration is also given to alternative technologies such as IGP metric based traffic engineering and IGP fast convergence, and to how quatitive decisions can be made on the relative benefits of the different approaches.
