Network Disaster RECOVERYINTRODUCTIONCommunication channels are electrical signals or electromagnetic waves for communication, then this type of communication is known as telecommunication. A telecommunications network is a set of terminal nodes and links that are connected to establish telecommunications between terminals. Transmission links connect nodes that use circuit switching, message switching, or packet switching to pass the signal through the appropriate links and nodes to reach the correct destination terminal. Each endpoint on the network is assigned a unique address so that messages or connections can be routed to the exact endpoint. Telecommunications networks provide high reliability for normal operations and, in hardware associated with the network, software failures. Although disasters do happen and can cause enormous damage without excellent network emergency planning. EXPLANATION OF THE DOCUMENT This topic mainly informs us about the different approaches to plan and manage disaster recovery, so that everyone involved can effectively mitigate these events. In today's world, communication is crucial to survival and security, even beyond the health and safety of the world. With the increasing penetration of the Internet from residential use, combined with commercial and otherwise important traffic carried over backbone networks, the impacts of service interruptions continue to be critical for many segments of society. Network disaster recovery (NDR) has become faster and more crucial in recent years, with catastrophic natural disasters occurring in different parts of the world due to various causes, with different responses...... middle paper.... ..Notify all purported parties so that they can take action.• Isolate affected organizations so that damage cannot spread.• Repair affected critical systems so that procedures can be summarized.SUMMARYThe Communication is very important during disasters and network disaster recovery (NDR) have become the most timely and crucial in recent years and disaster recovery plans are usually part of a larger and more extensive whole. Resources must be used correctly. In the event of a network disaster, planning should be done to develop a short-term recovery plan and a long-term recovery plan, including how to resume normal business operations during the disaster. The most important part of network disaster management is prioritizing the order of functions that resume.BIBILOGRAPHY1. http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5681010
