1 gru 2018 · Therefore, this paper presents a comparison of the performance of both TCP and UDP to precisely determine which of these protocols is better. Network Simulator version 2.35 (NS2) is utilized...
UDP is faster than TCP, and the simple reason is because its non-existent acknowledge packet (ACK) that permits a continuous packet stream, instead of TCP that acknowledges a set of packets, calculated by using the TCP window size and round-trip time (RTT).
1 sty 2018 · The study evaluates the performance of TCP and UDP in terms of throughput, delay, and packet loss under different network conditions, including different traffic loads and network topologies. ...
UDP: User Datagram Protocol [RFC 768] • “no frills,” “bare bones” Internet transport protocol • “best effort” service, UDP segments may be: –lost – delivered out of order to app • connectionless: – no handshaking between UDP sender, receiver – each UDP segment handled independently of others Why is there a UDP? • no ...
However, there is still a need to clearly study the performance of UDP and TCP in different network metrics and scenarios. Thus, this paper provides the performance comparison among UDP and TCP to precisely study the performance of these two protocols with different packet size and bandwidth.
UDP: Summary 1. UDP provides flow multiplexing using port #s 2. UDP optionally provides error detection using the checksum 3. UDP does not have error or loss recovery mechanism
UDP Versus TCP (1) z Choice of UDP versus TCP is based on: – Functionality – Performance z Performance – TCP’s window-based flow control scheme leads to bursty bulk transfers (not rate based) – TCP’s “slow start” algorithm can reduce throughput – TCP has extra overhead per segment – UDP can send small, inefficient datagrams
