Telecommunication Networks : CRC Press : 9781439846360 : 1439846367 : 05 Dec 2011 : "Preface The telecommunication infrastructure is perhaps the most impressive network developed by humankind. Almost all the technical knowledge forming the basic human know-how is exploited in the telecommunication network: from quantum field theory needed to study optical amplifier noise to software architectures adopted to design the control software of the network, from abstract algebra used in error correcting codes and in network design algorithms to thermal and mechanical modeling adopted in the design of telecommunication equipment platforms. The network is present almost everywhere in the world, allowing seamless communication of sounds and images through a chain of different types of equipment produced by several equipment vendors. Communicationis carried out smoothly not only in normal conditions, but its quality is also monitored continuously, allowing it to survive failure of individual comp
