Abstract
Diplomová práca je venovaná problematike sieťových prvkov. V úvode dokumentu sú popísané technické aspekty ako je vnútorná štruktúra sieťových prvkov a riadiace mechanizmy slúžiace k rozlíšeniu služieb a podpore ich kvalitatívnych požiadaviek. V prvej kapitole sú uvedené riadiace mechanizmy od tých najjednoduchších, ako je FIFO, až po sofistikované, akým je CBWFQ. Opomenuté nie sú ani druhy aktívneho manažmentu front, ktoré sú rozobraté v časti Riadiaci člen. Veľkú úlohu pri rozlíšení služieb hrajú procesy značenia a klasifikácie paketov. Druhá kapitola je venovaná najperspektívnejšiemu štandardu DiffServ. Obsahuje časti venované architektúre, značkovaniu paketov, kódovému slovu DSCP a záver kapitoly je venovaný spôsobom správania počas preskoku a to prednostné odoslanie EF a technike zaručeného odoslania AF. Tretia kapitola uvádza prehľad najbežnejších neurónových sietí, ich vlastnosti a posudzuje ich vhodnosť nasadenia v sieťovom prvku. Samotný návrh smerovača a jeho konštrukcia v programovom prostredí Matlab/Simulink je predmetom štvrtej kapitoly. Okrem použitých blokov z knižníc Simulinku je uvedené ich nastavenie a funkcia v zapojení. Následne sú zhodnotené výsledky a vyvodené závery.
Master’s thesis is dedicated to the issue of network element. In the first part are described technological aspects as the internal structure of network elements and control mechanisms that provide differentiaton of services and support their quality requirements. In the first chapter are listed control mechanisms from most simple like FIFO to the more sophisticated like CBWFQ. Active queue managements are not missing and they are described in the section Riadiaci člen. Significant role in the differentiation of services have processes marking and pakets classification. The second chapter is devoted most promising standard DiffServ. Contains section devoted to architecture, paket marking, code point DSCP and the final part is devoted to the types of per-hop behavior and it is expedited forwarding EF and technique assured forwarding AF. The third chapter gives an overview common models of neural networks, their properties and assess their suitability for deployment in network elements. The routher design itself and its structure in programming environment Matlab/Simulink is the subject of the fourth chapter. Except used bloks from Simulink library is described their setting and function in the wiring. Consequently results are reviewied and conclusions drawn.
