The study examines the operation and performance differences of TCP, UDP and QUIC protocols in the modern network environment. TCP provides reliable, connection-oriented communication, but latency and head-of-line blocking can hamper performance. UDP is faster but less reliable, while QUIC uses UDP to address TCP's limitations, reduce latency, support multiplexing, and connection migration between networks. This research summary analyzes the effectiveness of QUIC and UDP in a real network environment, paying particular attention to data flow control and traffic periodicity. In a real data traffic environment, in the case of different combinations of environmental parameters (garden size, segment size, transmission rate), a 10 MB file was copied between nodes using the UDP and QUIC protocols. In addition to the new delivery capabilities of the QUIC mechanism, we present the special characteristics of the periodicity of the arrival intervals of the regulated UDP traffic of the data stream.
Kivonat
A tanulmány a TCP, UDP és QUIC protokollok működését és teljesítménybeli különbségeit vizsgálja a modern hálózati környezetben. A TCP megbízható, kapcsolatorientált kommunikációt biztosít, ám a késleltetés és a "head-of-line" blokkolás hátráltathatja a teljesítményt. Az UDP gyorsabb, de kevésbé megbízható, míg a QUIC az UDP-t használva jól kezeli a TCP korlátait, csökkenti a késleltetést, támogatja a multiplexelést és a hálózatok közötti kapcsolat-migrációt. Jelen kutatási összefoglaló elemzi a QUIC és az UDP hatékonyságát valós hálózati környezetben, különös figyelmet fordítva az adatfolyam szabályozásra és a forgalom periodicitására. Valós adatforgalmi környezetben különböző környezeti paraméter (kertméret, szegmensméret, átviteli ráta) kombinációk esetén egy 10 MB méretű állomány ismételt átmásolása történt meg UDP, illetve QUIC protokollt alkalmazó csomópontok között. A QUIC mechanizmus új szállítási képességei mellett az adatfolyam szabályozott UDP forgalom beérkezési időközei periodicitásának speciális jellemzőit mutatjuk be.
