Introduction Transmission Control Protocol (TCP) is a widely used protocol for data transmission over internet. However, data transmission over TCP is not always error-free. transmission can be disrupted due to several reasons such as network congestion, packet loss, or failure of intermediate devices. In such cases, TCP uses a loss recovery technique to recover lost data and retransmit it. This technique is crucial in ensuring reliability of data transmission over internet. In this article, we will discuss fast recovery technique for loss recovery in TCP. Understanding TCP loss recovery technique TCP uses a three-way handshake mechanism to establish a connection ...

Introduction Access control lists (ACLs) are an important component of network security. ACLs are used to regulate network traffic and restrict access to network resources. An ACL is a set of rules that is applied to a network interface, router or firewall, which dictates which packets are allowed to pass through and which are dropped. ACLs can be either standard or extended, and they can be configured to allow or deny traffic based on source and destination IP addresses, protocols, and port numbers. In this article, we will explore extended access list in network security, its importance, and how to ... Read More

Introduction When building client-server applications using sockets, it's essential to assign a unique port number to each client to ensure proper communication between server and clients. By explicitly assigning a port number to each client, server can identify and communicate with individual clients without confusion or overlap. In this article, we'll explore importance of assigning port numbers to clients and how to do so effectively. What is a port number? In context of networking, a port number is a 16-bit unsigned integer that uniquely identifies a specific process to which a network packet is directed. When a client sends a ... Read More
