TCP follows the flow control mechanism that ensures a large number of packets are not sent to the receiver at the same time, while UDP does not follow the flow control mechanism. Ordering TCP uses ordering and sequencing techniques to ensure that the data packets are received in the same order in which they are sent.
To flow or not to flow? - Cisco Blogs May 07, 2015 Chapter 2. The Transport Layer: TCP, UDP, and SCTP User Datagram Protocol. UDP is a connectionless protocol, and UDP sockets are an example of datagram sockets. SCTP: Stream Control Transmission Protocol. SCTP is a connection-oriented protocol that provides a reliable full-duplex association Flow control; Full-duplex: an application can send and receive data in both directions on a given

It does not rely on UDP for this, and using TCP for flow and congestion control would be inefficient. In fact, most real-time applications have their own special flow-control requirements that the generic control provided by TCP cannot provide. Basically, UDP-based real-time applications must be … Ethernet flow control - Wikipedia
Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to ensure zero packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.
User Datagram Protocol (UDP) is more efficient in terms of both latency and bandwidth. UDP Header – UDP header is 8-bytes fixed and simple header, while for TCP it may vary from 20 bytes to 60 bytes. UDP is a connectionless protocol, and it can be used when speed is the main issue, and providing flow control, reliability, and that sort of mechanism would slow down the connection. So, we can quickly compare the two options at the transport layer.
