This project is based on the basic Networking terminologies. The project shows the Port Address Translation using the Routing Information Protocol version 2 i.e. RIP v2 protocol. Port Address Translation (PAT) is Network Address Translation technique in which the packet from a private LAN network reaches ISP router taking a private IP with specified port. All the packets sent from all the nodes and routers in LAN through a single private IP address but with different ports hence hiding the information of the LAN network.
Networking is a common synonym for developing and maintaining contacts and personal connections with a variety of people who might be helpful to you and your career.
Networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. It is an especially important aspect of career management in the financial services industry, since it is helps you keep abreast of: Types of networks: Local area network: A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as home, school, computer laboratory, office building, or closely positioned group of buildings. Each computer or device on the network is a node. Current wired LANs are most likely to be based on Ethernet technology, although new standards like ITU-T G.hn also provide a way to create a wired LAN using existing home wires (coaxial cables, phone lines and power lines). Wide area network: A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances, using a communications channel that combines many types of media such as telephone lines, cables, and air waves. A WAN often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer. NAT is similar to Classless Inter-Domain Routing (CIDR) in that the original intention for NAT was to slow the depletion of available IP address space by allowing many private IP addresses to be represented by some smaller number of public IP addresses. Since then, it’s been discovered that NAT is also a useful tool for network migrations and mergers, server load sharing, and creating “virtual servers.” So in this chapter, I’m going to describe the basics of NAT functionality and the terminology common to NAT. At times, NAT really decreases the overwhelming amount of public IP addresses required in your networking environment. And NAT comes in really handy when two companies that have duplicate internal addressing schemes merge. NAT is also great to have around when an organization changes its Internet service provider (ISP) and the networking manager doesn’t want the hassle of changing the internal address scheme. Here’s a list of situations in which it’s best to have NAT on your side: You need to connect to the Internet and your hosts don’t have globally unique IP addresses. You change to a new ISP that requires you to renumber your network. This project is based on the basic Networking terminologies.
