Communication Models for Description of TCP Protocol and its' Mechanisms

U ovom radu objašnjene su osnove UML (eng. UnifiedModelingLanguage) jezika te pripadajući dijagrami koji se koriste za opisivanje sustava. Rad se u trećem poglavlju dotiče i TCP (eng. TransmissionControlProtocol) protokola, jer mehanizmi i algoritmi koji su objašnjeni u ovom radu se vežu uz TCP protokol. Četvrto, peto, šesto i sedmo poglavlje opisuju mehanizme i algoritme koje koristi TCP protokol kako bi ostvario siguran prijenos podataka. U svakom od tih poglavlja su pojedini mehanizmi i algoritmi objašnjeni putem UML dijagrama i to dijagramom međudjelovanja, suradnje i dijagramom stanja i prijelaza.This paper explains the basics of the UML (UnifiedModelingLanguage) and the associated diagrams used to describe asystem. The paper in the third chapter also discusses the TCP (TransmissionControlProtocol)because the mechanisms and algorithms explained in this paper are related to the TCP protocol. Chapters four, five, six, and seven describe the mechanisms and algorithms used by the TCP protocol to achieve secure data transmission. In each of these chapters, individual mechanisms and algorithms are explained via UML diagrams, namely statechart diagram, collaboration diagram and the sequence diagram
