MODBUS APPLICATION PROTOCOL SPECIFICATION V1

The size of the MODBUS PDU is limited by the size constraint inherited from the first MODBUS implementation on Serial Line network (max. RS485 ADU = 256 bytes). Therefore: MODBUS PDU for serial line communication = 256 - Server address (1 byte) - CRC (2 bytes) = …

Introduction to Socket Programming

programmer is that a TCP connection provides a reliable connection over which data can be transferred with little effort required on the programmers part; TCP takes care of the reliability, flow control, congestion control for you. First the basic concepts will be discussed, then we will learn how to implement a simple TCP client and server. 2.)

Introduction to Sockets Programming in C using TCP/IP

TCP vs UDP TCP is used for services with a large data capacity, and a persistent connection UDP is more commonly used for quick lookups, and single use query-reply actions.

CUBIC: A New TCP-Friendly High-Speed TCP Variant

TCP-Vegas [10] measures the difference (δ) between expected throughput and actual throughput based on round-trip de-lays. When δ is less than a low threshold α, TCP-Vegas believes the path is not congested and thus increases the sending rate. When δ is larger than a upper threshold β,

Understanding Layer 2, 3, and 4 Protocols

Transmission Control Protocol (TCP) is used in HTTP applications to ensure this successful packet delivery. Other applications will make use of different Transport layer protocols. TFTP, for example, uses the User Datagram Protocol (UDP) as its Layer 4 transport because it does not require the guaranteed deliv-ery provided by TCP.
