Oct 09, 2019 · The User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) are the “siblings” of the transport layer in the TCP/IP protocol suite. They perform the same role, providing an interface between applications and the data-moving capabilities of the Internet Protocol (IP), but they do it in very different ways.
User Datagram Protocol. flow control. The source port address on the UDP user datagram header defines _____. the process running on the sending computer. Flow control Congestion control UDP TCP Header format, connection management, checksum Congestion Control Note: This class lecture is based on Chapter 3 of the textbook (Kurose and Ross) and the figures provided by the authors. UDP checksum generation validation done by the end system, by setting socket options aproppriately. It is up to the application what it wants to do with an UDP datagram with incorrect checksum. But this is becoming off-topic now. Flow controlling TCP has flow control: UDP has no flow control: Data transmission order: TCP gives guarantee that the order of the data at the receiving end is the same as the sending end No guarantee of the data transmission order: Header Size 20 bytes: 8 bytes: Acknowledgment: TCP acknowledges the data reception: UDP has no acknowledgment TCP (Transmission Control Protocol) provides the service with connection and UDP (User Datagram Protocol) provides connectionless services to the user. UDP is basically just IP with an additional short header. Now, we will see these two protocols in brief. First, let us see UDP. TCP and UDP Protocols UDP (User Datagram Protocol):
UDP is used when acknowledgement of data does not hold any significance. UDP is good protocol for data flowing in one direction. UDP is simple and suitable for query based communications. UDP is not connection oriented. UDP does not provide congestion control mechanism. UDP does not guarantee ordered delivery of data. UDP is stateless.
Source Port : Source Port is 2 Byte long field used to identify port number of source. Destination Port : It is 2 Byte long field, used to identify the port of destined packet. Length : Length is the length of UDP including header and the data. It is 16-bits field. Checksum : Checksum is 2 Bytes long field. It is the 16-bit one’s complement of the one’s complement sum of the UDP header Solved: When to use Flow Control? - Hewlett Packard
