Bsc CSIT Semester 4 – Computer Networks – Unit 5: Transport Layer (6Hrs.)

TCP (Transmission Control Protocol) is a connection-oriented, reliable, and byte-stream transport layer protocol. It ensures that data is delivered accurately and in sequence between two communicati

Why TCP is Connection-Oriented and Reliable TCP (Transmission Control Protocol) is called connection-oriented because: 1. Before any data is sent, a connection is established between the sender and

Open-Loop vs Closed-Loop Congestion Control 1. Open-Loop Congestion Control Definition: Open-loop congestion control prevents congestion before it happens. It uses policies and flow control mechani

TCP Push Operation Definition: The TCP Push (PSH) operation is a mechanism used in the Transmission Control Protocol (TCP) to prompt the immediate delivery of data to the receiving application, rath

Relationship between Transport Layer and Network Layer The Transport Layer and the Network Layer are two important layers of the OSI Model that work together to provide end-to-end communication betwee

Introduction Congestion in a network occurs when the demand for resources (like bandwidth, buffers, or processing capacity) exceeds the network’s capacity. This leads to packet loss, delays, and deg

Connection-Oriented Service A connection-oriented service is a type of network communication in which a connection is first established between sender and receiver before any data is transmitted. It

What is a Token Bucket? The Token Bucket is a traffic shaping and rate control mechanism used in computer networks. It controls how much data a sender can transmit over the network, allowing bursts
