Jul 13, 2020 · UDP and TCP are two protocols that are responsible for determining how data is exchanged on the internet. Since both are built on the IP protocol, they do share similarities. However, their differences make them suitable for different use cases. Regardless of their similarities and differences, UDP and TCP are among the most widely used protocols.

TCP provides apps a way to deliver (and receive) an ordered and error-checked stream of information packets over the network. The User Datagram Protocol (UDP) is used by apps to deliver a faster stream of information by doing away with error-checking.
TCP is a connection oriented stream over an IP network. It guarantees that all sent packets will reach the destination in the correct order. This imply the use of acknowledgement packets sent back to the sender, and automatic retransmission, causing additional delays and a general less efficient transmission than UDP.

TCP 传输协议：TCP 协议是一TCP (Transmission Control Protocol)和UDP(User Datagram Protocol)协议属于传输层协议。 其中TCP提供IP环境下的数据 可靠传输 ，它提供的服务包括 数据流 传送、可靠性、有效流控、全双工操作和多路复用。
User Datagram Protocol (UDP) works on the transport layer which is the third layer of the TCP/IP protocol suite. In contrast to the TCP protocol, it is a connectionless protocol as it does not establish a connection before sending the data over the network for communication. Re: Dos Attack: TCP/UDP Chargen?! It's impossible to tell the exact origin as these were almost definitely spoofed with your IP. This could be part of a zombie scan or a misconfiguration of an attack but both of these are just background noise that you get from being on the internet. What is User Datagram Protocol (UDP/IP)? UDP is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communications by not requiring what’s known as a “handshake”, allowing data to be transferred before the receiving party agrees to the communication. The diagram below shows clearly the way TCP/IP protocol suite relates to the TCP/IP model. Host-to-Host Layer Protocols. Two protocols: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are defined for transmitting datagrams. We will look at the details of both these protocols as well as their interaction with the upper layer. Nov 21, 2019 · How TCP and UDP work. TCP is the most commonly used protocol on the internet because it’s considered to be more reliable. Here’s what it does to send your data: TCP assigns each data packet a unique identifier and a sequence number. This lets the receiver identify which packet was received and which one is arriving next.
