TCP/IP PROTOKOLLARINING ZAMONAVIY MODIFIKATSIYALARINI TAHLIL QILISH

KIRISH: ushbu maqolada tarmoq protokollaridan TCP/IP stekining zamonaviy modifikatsiyalari — QUIC, MPTCP, SCTP va IPv6 — tizimli ravishda tahlil qilinadi. internet trafigining eksponent tarzda o‘sib borishi an’anaviy TCP/IPv4 arxitekturasida kechikish, o‘tkazuvchanlik va xavfsizlik jihatlarida cheklovlarni yuzaga keltirmoqda. MAQSAD: tadqiqotning maqsadi — zamonaviy protokollarni tahlil qilish orqali ularning mavjud muammolarni hal etishdagi afzalliklarini aniqlash va tarmoq infratuzilmasini loyihalashda amaliy yo‘riqnoma ishlab chiqishdir. MATERIALLAR VA METODLAR: tadqiqotda protokollarning texnik xususiyatlari, kechikishlarni kamaytirish mexanizmlari, xavfsizlikni ta’minlash usullari va o‘tkazuvchanlikni oshirish imkoniyatlari qiyosiy tahlil qilindi. NATIJALAR VA MUHOKAMA: natijalar shuni ko‘rsatdiki, QUIC protokoli kechikishni kamaytiradi va xavfsizlikni mustahkamlaydi; MPTCP bir nechta ulanishlarni birlashtirib ishonchlilikni oshiradi; SCTP oqimlarni boshqarish va signalizatsiya uchun samarali vosita hisoblanadi; IPv6 esa manzillarni kengaytirish va xavfsizlikni yaxshilash imkonini beradi. ushbu modifikatsiyalar yuqori tezlikdagi tarmoqlar, mobil aloqa tizimlari, IoT va 5G/6G muhitida samarali qo‘llanilishi mumkin. XULOSA: zamonaviy protokollar TCP/IP arxitekturasining cheklovlarini bartaraf etib, tarmoq infratuzilmasini yanada samarali va xavfsiz qilish imkonini beradi. tadqiqot natijalari amaliyotda protokollar tanloviga yo‘riqnoma sifatida xizmat qilishi mumkin.

INTRODUCTION: this article provides a systematic analysis of modern modifications of the TCP/IP stack — QUIC, MPTCP, SCTP, and IPv6. with internet traffic growing exponentially, the traditional TCP/IPv4 architecture faces increasing limitations in terms of latency, throughput, and security. PURPOSE: the aim of the study is to examine how these protocols address existing challenges and to provide practical guidance for network infrastructure design. MATERIALS AND METHODS: the study applied comparative analysis of protocol features, mechanisms for reducing latency, enhancing security, and improving throughput. RESULTS AND DISCUSSION: QUIC reduces latency and strengthens security; MPTCP improves reliability by combining multiple connections; SCTP offers efficient stream management and signaling; IPv6 expands addressing capacity and enhances security. these modifications prove effective in high-speed networks, mobile communication systems, IoT, and 5G/6G environments. CONCLUSION: modern protocol modifications overcome TCP/IP limitations and enable more efficient and secure network infrastructures. the findings serve as practical guidelines for protocol selection in contemporary network design.
