- Holcim Uses Network Optimization to Manage Supply Chain Risk and Optimize Costs
- Holcim U.S. is a wholly owned subsidiary of Holcim of Switzerland. Over the last few years, where demand has outstripped supply, managing make-versus-buy decisions is also a key decision that needs to be regularly revisited as demand plans are updated. To support this type of analysis, Holcim recognized the value...

- A Fresh Look at Access Aggregation: BLC 6000 Multi-Service Access Platform
- At what point does access aggregation become network transport? Why are some access aggregation solutions better suited for service provider networks than traditional edge aggregation network elements than others? These questions are often debated by small to mid-sized service providers and decisions inevitably come down to price, performance and value....

- Analysis Techniques for WiMAX Network Design Simulations
- The initial analysis of the WiMAX uplink interference problem indicates a dependence upon a process scheduling which cannot be modeled accurately. Given this, one might therefore consider a Monte Carlo approach. However, further analysis shows that the details of this dependence are not relevant to the engineering question. One can...

- Buy-at-Bulk Network Design With Protection
- This paper considers approximation algorithms for buy-at-bulk network design, with the additional constraint that demand pairs be protected against edge or node failures in the network. In practice, the most popular model used in high speed telecommunication networks for protection against failures, is the so-called 1+1 model. In this model,...

- Multiobjective Network Design for Realistic Traffic Models
- Network topology design problems find application in several real life scenarios. However, most designs in the past either optimize for a single criterion like delay or assume simplistic traffic models like Poisson. Such assumptions make the solutions inapplicable in the practical world. This paper formulates and solves a multiobjective network...

- Practical Large-Scale Network Design With Variable Costs for Links and Switches
- This paper considers communication network design problems that arise in the real world, with large numbers of nodes and link and switch costs dependent upon their traffic capacity. Such costs, in turn, depend upon network topology so are not fixed at the start of, or through, any optimisation process. Realistic...

- On Survivable Access Network Design: Complexity and Algorithms
- With economic constraints and limited routing capability, the structure of an access network is typically a "fat tree", where the terminal has to relay the traffic from another terminal of the same or higher level. New graph theory problems naturally arise from such features of access network models, different from...
