What You Need to Know

The following terms and concepts may help as you read this chapter.

Encapsulation Method

Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set

up a WAN connection to the Internet, you need to use the same encapsulation method used by your

ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP

over Ethernet), they should also provide a username and password (and service name) for user

authentication.

WAN IP Address

The WAN IP address is an IP address for the Device, which makes it accessible from an outside

network. It is used by the Device to communicate with other devices in other networks. It can be

static (fixed) or dynamically assigned by the ISP each time the Device tries to access the Internet.

If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and

DNS server IP address(es).

ATM

Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data

transfer. ATM uses fixed-size packets of information called cells. With ATM, a high QoS (Quality of

Service) can be guaranteed. ATM uses a connection-oriented model and establishes a virtual circuit

(VC) between Finding Out More

PTM

Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2 standard. In PTM,

packets are encapsulated directly in the High-level Data Link Control (HDLC) frames. It is designed

to provide a low-overhead, transparent way of transporting packets over DSL links, as an

alternative to ATM.

3G

3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is

optimized as multiple users share the same channel and bandwidth is only allocated to users when

they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet

access to mobile devices.

IPv6 Introduction

IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The

increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10

38

IP

addresses. The Device can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and

supports IPv6 rapid deployment (6RD).

IPv6 Addressing

The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This

is an example IPv6 address

2001:0db8:1a2b:0015:0000:0000:1a2f:0000

.

IPv6 addresses can be abbreviated in two ways:

•

Leading zeros in a block can be omitted. So

2001:0db8:1a2b:0015:0000:0000:1a2f:0000

can be written as

2001:db8:1a2b:15:0:0:1a2f:0

.

Chapter 5 Broadband

VMG8924-B10A and VMG8924-B30A Series User’s Guide

48

•

Any number of consecutive blocks of zeros can be replaced by a double colon. A double

colon can only appear once in an IPv6 address. So

2001:0db8:0000:0000:1a2f:0000:0000:0015

can be written as

2001:0db8::1a2f:0000:0000:0015

,

2001:0db8:0000:0000:1a2f::0015

,

2001:db8::1a2f:0:0:15

or

2001:db8:0:0:1a2f::15

.

IPv6 Prefix and Prefix Length

Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An

IPv6 prefix length specifies how many most significant bits (start from the left) in the address

compose the network address. The prefix length is written as “/x” where x is a number. For

example,

2001:db8:1a2b:15::1a2f:0/32

means that the first 32 bits (

2001:db8

) is the subnet prefix.

IPv6 Subnet Masking

Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided

into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each

character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal

characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.

IPv6 Rapid Deployment

Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4

network. When the Device has an IPv4 WAN address and you set

IPv6/IPv4 Mode

to

IPv4 Only

,

you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.

The Device generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the

ISP’s Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The local

network can also use IPv4 services. The Device uses it’s configured IPv4 WAN IP to route IPv4

traffic to the IPv4 Internet.

Dual Stack Lite

Use Dual Stack Lite when local network computers use IPv4 and the ISP has an IPv6 network.

When the Device has an IPv6 WAN address and you set

IPv6/IPv4 Mode

to

IPv6 Only

, you can

enable Dual Stack Lite to use IPv4 computers and services.

The Device tunnels IPv4 packets inside IPv6 encapsulation packets to the ISP’s Address Family

Transition Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also

use IPv6 services. The Device uses it’s configured IPv6 WAN IP to route IPv6 traffic to the IPv6

Internet.
