Hardware Manual for the Model CG814WG Wireless Cable Modem Gateway
What is a Router?
A router is a device that forwards traffic between networks based on network layer information in the data and on routing tables maintained by the router. In these routing tables, a router builds up a logical picture of the overall network by gathering and exchanging information with other routers in the network. Using this information, the router chooses the best path for forwarding network traffic.
Routers vary in performance and scale, number of routing protocols supported, and types of physical WAN connection they support. The CG814WG Wireless Cable Modem Gateway is a small office router that routes the IP protocol over a
Routing Information Protocol
One of the protocols used by a router to build and maintain a picture of the network is the Routing Information Protocol (RIP). Using RIP, routers periodically update one another and check for changes to add to the routing table.
The CG814WG Gateway supports both the older
IP Addresses and the Internet
Because TCP/IP networks are interconnected across the world, every machine on the Internet must have a unique address to make sure that transmitted data reaches the correct destination. Blocks of addresses are assigned to organizations by the Internet Assigned Numbers Authority (IANA).
Individual users and small organizations may obtain their addresses either from the IANA or from an Internet service provider (ISP). You can contact IANA at www.iana.org.
The Internet Protocol (IP) uses a
For example, the following binary address:
11000011 00100010 00001100 00000111
is normally written as:
195.34.12.7
