Duda Nagle is a technique used to improve the efficiency of TCP over high-latency networks. It attempts to reduce the number of small packets that are sent over the network, which can improve performance and reduce bandwidth usage.

Duda Nagle was developed by John Nagle in 1984. It is based on the idea that it is more efficient to send a single large packet than multiple small packets. This is because the overhead of sending a packet is relatively high, so sending fewer packets can reduce the overall overhead.

Duda Nagle is used in a variety of operating systems and network stacks. It is typically enabled by default, but it can be disabled if necessary.

TCP

TCP is a connection-oriented protocol, which means that it establishes a connection between two hosts before any data is transmitted. This allows TCP to provide reliable data transmission, as it can retransmit lost or corrupted data. TCP also provides flow control, which prevents one host from sending data faster than the other host can receive it.

Packets

Packets are the basic unit of data that is sent over a network. They are typically small, ranging in size from a few bytes to a few kilobytes. Packets are sent from one host to another over a network interface card (NIC). The NIC encapsulates the packet in a frame, which includes the packet's destination and source addresses, as well as other information. The frame is then sent over the network.
