Abstract The paper addresses the lexicographically maximal risk-disjoint/minimal cost path pair problem that aims at finding a of paths between two given nodes, which is shortest (in terms cost) among those have fewest risks in common. This particular importance telecommunication network design, namely concerning resilient routing models where both primary and backup to be calculated minimize r...

We define a family of high-rate binary LDPC codes for ADSL. We present simulation results that show the performance that can be achieved by these codes on a binary additive white Gaussian noise (AWGN) channel. LDPC codes exhibit performance very close to the capacity limit with moderate decoding complexity and are thus well suited for channel coding applications in ADSL systems.

This paper considers the impact of European telecom regulation on the value of affected companies. Employing a repeating AR-GARCH model, I compare the effect of three types of regulation which are categorized based on the addressed subject, i.e. cross-market, country-specific and company-specific regulation. While standard event study approaches are a special case of ARGARCH models, the approxi...

This paper reviews some basic concepts about network management and introduces a new approach for the management of telecommunication networks, using SIS (System for the Integration of Supervision). The approach is based on the gradual integration of the existing proprietary management systems, while simultaneously moving towards the new ITU-T network management standards, namely TMN.
