Chapter 2: Networking Communications Data communication involves the flow of packets of data from one device to another. These devices include personal computers, Ethernet and USB hubs, cable modems, digital routers and switches, and highly integrated devices that combine functions, like the Wireless Cable Gateway. The gateway integrates the functionality often found in two separate devices into one.
Chapter 2: Networking Example: The Wireless Cable Gateway offers a number of built-in web pages which you can use to configure its networking side; when you communicate with the networking side, your communication is following this path. Each packet on the Internet addressed to a PC in your home travels from the Internet downstream on the cable company’s system to the WAN side of your Wireless Cable Gateway.
Chapter 2: Networking address by various means, including a DHCP server, by you directly entering it, or sometimes by a PC generating one of its own. Ethernet requires that each TCP/IP stack on the Wireless Cable Gateway also have associated with it an Ethernet MAC (Media Access Control) address.
Chapter 2: Networking CM (Cable Modem) Mode provides basic home networking. In this mode, two IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the cable modem section only. This stack receives its IP address from the cable company during CM initialization. It uses the MAC address printed on the label attached to the Wireless Cable gateway.
Chapter 2: Networking RG (Residential Gateway) Mode provides basic home networking plus NAT (Network Address Translation). In this mode, three IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the Cable Modem section only.
