What Is a Broadband Router?

A Broadband Router is oftentimes termed as a Home Residential Gateway, since several Broadband Routers are used by home consumers. However, small enterprise also make use of this specialist routing device to supply a High Speed Internet Service for the business LAN.

Broadband Routers normally combine several popular features of other networking devices. In addition to normal routing services, they normally supply a built-in network switch, firewall features and commonly a DHCP Server.

A standard router is designed to build routing tables by making use of a common routing protocol alongside peer routers, and employ that routing table to determine which interface of that to transmit an IP Packet or stream of IP Packets. When the router receives an Ethernet frame containing an IP packet inside payload, it checks the destination IP Address inside packet, performs a 'Logical And' process around the IP Address and assigned Network Mask. The result provides the destination Network Address which the router actively seeks in the routing table. A router might have multiple interfaces that connect with different parts of an Internetwork, including an Ethernet Interface, DSL interface, Cable Interface or Point-to-Point interface for starters.

Some routers are created to support only a few connections and handle a rather small amount of data traffic, whilst some ISP routers have become powerful devices that will handle many an incredible number of packets per second.

A Broadband router will usually have a DSL interface that connects via your phone line for a ISP, or a Cable Interface which connects by using an Ethernet Cable by way of a Cable Modem and so on towards the ISP using a coaxial cable. Sometimes Broadband Routers are classified as Internet Connection Sharing simply because they allow several peripheral devices including PCs to share a common DSL or Cable connection.

Most consumer Broadband Routers provides an in-built 4-port Ethernet switch for link with local devices through an Ethernet patch cable as well as a Wireless interface complying with one of the IEEE 802.11 standards this type of IEEE 802.11g. This allows many computers to have a very mobile capability and it is ideal for such devices as Laptop Computers and Smartphones with wireless capability. Both the wired and wireless interfaces is going to be served with a DHCP Server to dynamically allocate IP Addresses to connected devices. Additionally the router will support Network Address Translation (NAT) to permit all local devices to share with you a single IP Address when accessing the Internet.

Broadband Wireless Routers need another layer of security to guard the Wireless LAN from potential interlopers and hackers. Most modern Broadband Routers support a mixture of security measures for example WPA - WiFi Protected Access and MAC Address filtering. Some of the older models only supported WEP - Wired Equivalent Privacy which only provided rudimentary security, and indeed may be hacked with a determined hacker or enthusiast.

Should you decide on a Wired or Wireless version of your Internet Connection Gateway? The choice is yours, having said that that for any little more money you receive a model containing both capabilities. You may need to learn a extra regarding how wireless networks operate as well as the additional security measures had to fully protect this type of network.

For home consumer Broadband Routers I would recommend Netgear or Linksys, and for business routers then you cannot go far wrong with Cisco.
