In this paper, we implement a modern serial backplane platform for telecommunication inter-rack systems. For combination high reliability and low cost protocol property, we applied high level data link control (HDLC) protocol with low voltage differential signaling (LVDS) bus for card to card communicated over backplane. HDLC protocol is a high performance with several operation modes and is fa...

Telecommunication companies generate a tremendous amount of data. These data include call detail data, which describes the calls that traverse the telecommunication networks, network data, which describes the state of the hardware and software components in the network, and customer data, which describes the telecommunication customers. This chapter describes how data mining can be used to unco...

در این پایان نامه روش مسیریابی برای شبکه موردی با استفاده از زیرساخت شبکه سلولی ارایه شده است. از آنجا که شبکه های سلولی جغرافیای زیادی را پوشش می دهند، هنگامی که شبکه موردی زیر پوشش شبکه سلولی است می توان از این شبکه متصل به زیرساخت، برای مسیریابی در شبکه های موردی استفاده نمود. دو سناریوی مسیریابی در نظر گرفته شده است: در سناریوی نخست همه گره ها دارای دو واسط سلولی و موردی هستند و در سناریوی ...

Currently telecommunication networks consist of heterogeneous networks, therefore controlling and managing the traffic in these networks will be complex tasks and difficult. Network management activities for these diverse networks require gathering and analyzing huge amount of data from the network. Then based on the activities involved in the network, decisions must be made at different times,...

We study the numerical stability problem that may take place when calculating the cumulative distribution function of the Hypoexponential random variable. This computation is extensively used during the execution of Monte Carlo network reliability estimation algorithms. In spite of the fact that analytical formulas are available, they can be unstable in practice. This instability occurs frequen...

Using telecommunication as an example, it is argued that the electronics industry badly needs a change in attitude towards reliability thinking. The role of thermal design and reliability qualification is discussed in context to current industrial needs for short design cycles and rapid implementation of new technologies. Current and future practices are discussed in the context of newly-emergi...
