Network Diagram with International Standard The connectivity Between Internet, WAN, LAN, Intranet, Server and Datacenter

The Connectivity Between The Internet and The System. Internet/Cloud Router Firewall VPN Wi-Fi Router WAN Switch DMZ Zone(All Server) DMZ Zone(Data center) LAN 2 Switch LAN 1 Switch LAN 1 connecting Switch LAN 2 connecting Switch User PC User PC

The Definition and Declaration of the Connectivity Connecting with Internet/cloud and router. The Internet is a global network connecting millions of computers. More than 100 countries are linked into exchanges of data, news and opinions. A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect. A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. Internet/Cloud Router Firewall

The Connection between Internet, Router and Firewall. The Connection Between the Router and The Internet and Firewall in details. Internet/Cloud Router Firewall Link Load Balance Wan Route LAN Route or NAT Bandwidth Manage Spam, Web Filter and DDOS Attack Intrusion Prevention System LAN Protection Wan Protection BTCL Bandwidth Any other ISP Bandwidth

The Connection Between Firewall and Server. Demilitarized zone (DMZ) Application Server Database Server Mail Server AD,DNS, Anti Virus,IIS Server Data Center DMZ: In computer networks, a DMZ (demilitarized zone) is a computer host or small network inserted as a "neutral zone" between a company's private network and the outside public network. It prevents outside users from getting direct access to a server that has company data.

The Connection Between The Firewall and VPN VPN: A Virtual Private Network (VPN) is a network technology that creates a secure network connection over a public network such as the Internet or a private network

The Connection Between The Firewall and Switch LAN 1 Switch LAN 2 Switch Switch: In networks, a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2).

The Connection Between The LAN Switch and User Hub Wi-Fi Router Switch Hub Wi-Fi Router User PC User PC User PC User PC User PC User PC Hub: A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. Wi-Fi Router: A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point. Network Cable: Networking cables are used to connect one network device to other network devices RJ-45 Connector: RJ45 is a standard type of connector for network cables such as those used in Ethernet networks.

Conclusion In This Presentation we describe about a standard international network diagram. Where we discussed briefly how the network work with internet/intranet, router, firewall, server, switch, hub and end user. If we flow this diagram, we hope that any computer network will run smoothly. Thanks’ for your valuable time to see this presentation. Mehedi Hassan System Administrator
