  • Page 62: Cable Modem (Cm) Section

    Chapter 3: 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 down- stream on the cable company’s system to the WAN side of your Wireless Cable Gateway.

  • Page 63: Three Networking Modes

    Chapter 3: Networking When a packet enters a network interface, it is offered to all the TCP/IP stacks associated with the device side from which it entered. But only one stack can accept it — a stack whose configured Ethernet address matches the Ethernet destination address inside the packet.
  • Page 64 Chapter 3: Networking Fig. 48 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.
