Hardware Manual for the Model CG814WG Wireless Cable Modem Gateway

IETF

Internet Engineering Task Force. An open international community of

 

network designers, operators, vendors, and researchers concerned with the

 

evolution of the Internet architecture and the smooth operation of the Internet.

 

Working groups of the IETF propose standard protocols and procedures for

 

the Internet, which are published as RFCs (Request for Comment) at

 

www.ietf.org.

IP

Internet Protocol. The main internetworking protocol used in the Internet.

 

Used in conjunction with the Transfer Control Protocol (TCP) to form TCP/IP.

IP Address

A four-position number uniquely defining each host on the Internet. Ranges of

 

addresses are assigned by Internic, an organization formed for this purpose.

 

Usually written in dotted-decimal notation with periods separating the bytes

 

(for example, 134.177.244.57).

ISP

Internet service provider.

LAN

See local area network.

local area network

LAN. A communications network serving users within a limited area, such as

 

one floor of a building. A LAN typically connects multiple personal

 

computers and shared network devices such as storage and printers. Although

 

many technologies exist to implement a LAN, Ethernet is the most common

 

for connecting personal computers.

MAC address

Media Access Control address. A unique 48-bit hardware address assigned to

 

every Ethernet node. Usually written in the form 01:23:45:67:89:ab.

Mbps

Megabits per second.

MSB

See Most Significant Bit or Most Significant Byte.

MTU

See Maximum Transmit Unit.

Maximum Transmit

The size in bytes of the largest packet that can be sent or received.

Unit

 

NAT

See Network Address Translation.

netmask

A number that explains which part of an IP address comprises the network

 

address and which part is the host address on that network. It can be

 

expressed in dotted-decimal notation or as a number appended to the IP

 

address. For example, a 28-bit mask starting from the MSB can be shown as

 

255.255.255.192 or as /28 appended to the IP address.

Network Address

A technique by which several hosts share a single IP address for access to the

Translation

Internet.
