Analysis and implementation of basic functionalities of network devices on data-plane

Ubrzanim razvojem čitave industrije, razvijale su se i rasle potrebe mrežnih infrastruktura, što lokalnih što operaterskih. Takav ubrzani rast i razvoj čeznuo je za promjenama. Dosadašnje metode implementacije takvih infrastrukturnih rješenja unošenjem naredbi kroz naredbeni redak, CLI, jednostavno nisu mogle odgovoriti na tražene zahtjeve za brzinom implementacije, izmjene, dodavanjem novih funkcionalnosti, smanjenju ljudskog faktora, optimizaciji performansi, troškova i sl. Vrlo brzo pronašlo se rješenje u obliku programski upravljivih mreža. Niti takav pristup nije ostao samo na tome. Industrija traži još, sve više, brže, snažnije. I naravno, nije se trebalo dugo čekati da bi se tadašnji SDN danas učinio još fleksibilnijim i mogli bi reći otvorenijim. Tako se došlo i do white-box switcheva i otkrića programskog jezika P4 koji čine revoluciju u području mrežnih tehnologija i pružaju mnogobrojne mogućnosti, posebno „krojenja“ mreže po vlastitim željama.With the accelerated development of the entire industry, needs of the local networks or service provider networks have evolved and grew. Such an accelerated growth and development yearns to changes. Current methods of implementing both, the simple or complex networks, by entering commands through the CLI interface, simply could not respond to the asked requests for speed of implementation, reconfigurability, adding new functionalities, human factor reduction, optimization of performance and costs. The solution was quickly found in the form of Software Defined Networks (SDN). But not even this approach remained just that. The industry is looking for more and more. More faster, more powerful, more open. And of course, it did not take too long to wait for the SDN to evolve into the something more flexible and to say, more opened. That way of innovation led the industry to the white-box switches and the creation of the P4 programming language which makes the revolution in the field of network technologies and provides numerous possibilities, especially implementing networks in our own way
