liboping is a library written in C for generating ICMP ECHO_REQUEST (i.e., ping packets). It supports parallel probing of multiple hosts and can transparently handle both IPv4 and IPv6 addresses. This library is designed with a object-oriented interface, making it very useful in network monitoring applications or other scenarios that require frequent ping operations. Here … Read more
1. OSI Model About the OSI seven-layer model: Application layer, Presentation layer, Session layer, Transport layer, Network layer, Data Link layer, and Physical layer. The seven-layer model and the protocols applied at each layer are shown in the figure below. So what protocols are used at each layer? We list some commonly used protocols in … Read more
In the computer networking architecture, the network layer (the third layer of the OSI model) is the core for achieving data transmission across networks, with the primary goal of providing end-to-end logical paths for hosts in different networks, and forwarding packets from the source host to the destination host through routing. The following sections will … Read more
Introduction to ICMP Protocol When there is an error in transmitting IP packets – for example, host unreachable, route unreachable, etc., the ICMP protocol will encapsulate the error information and send it back to the host. This gives the host a chance to handle the error, which is why it is said that protocols built … Read more

Ping Issue Analysis What is Ping Ping is a commonly used network management command and is also part of a communication protocol that belongs to the TCP/IP suite, suitable for Windows, Linux, and Unix. It checks whether the network is smooth or the network connection speed (time) is normal based on the reply feedback results. … Read more

Directory Some friends asked: Why can’t we go online without configuring an IP address? What is the IP protocol? This starts with the TCP/IP protocol; the Internet uses the TCP/IP protocol, among which the IP protocol is one of the most important protocols. The IP protocol sends data packets to the destination host based on … Read more
