3 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/CloudRouterFirewall
4 The Connection between Internet, Router and Firewall. The Connection Between the Router and The Internet and Firewall in details.Internet/CloudRouterFirewallLink Load BalanceWan RouteLAN Route or NATBandwidth ManageSpam, Web Filter and DDOS AttackIntrusion Prevention SystemLAN ProtectionWan ProtectionBTCL BandwidthAny other ISP Bandwidth
5 The Connection Between Firewall and Server. Demilitarized zone (DMZ)Application ServerDatabase ServerMail ServerAD,DNS, Anti Virus,IIS ServerData CenterDMZ: 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.
6 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
7 The Connection Between The Firewall and Switch LAN 1 SwitchLAN 2 SwitchSwitch: In networks, a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2).
8 The Connection Between The LAN Switch and User HubWi-Fi RouterSwitchHubWi-Fi RouterUser PCUser PCUser PCUser PCUser PCUser PCHub: 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 devicesRJ-45 Connector: RJ45 is a standard type of connector for network cables such as those used in Ethernet networks.
9 ConclusionIn 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 HassanSystem Administrator
