Specifications in preliminary manuals

are subject to change without notice.

PRELIMINARY

IP ADDRESS A 32-bit quantity representing a point of attachment to the Internet. It is

usually represented by four 8-bit integers separated by dots. Each decimal

integer represents a byte in an IP address. The IP address is divided into a

network part and a host part. For example, 192.9.211.151.

LOCAL AREA NETWORK

(LAN)

A group of interconnected computers and other devices.

MAC ADDRESS Media Access Control address that represents a unique physical address for

each port in a local area network.

MAP A network diagram showing devices managed by ECView.

MD5 MD5 Message-Digest is an algorithm that is used to create digital

signatures. It is intended for use with 32 bit machines and is safer than the

MD4 algorithm, which has been broken. MD5 is a one-way hash function,

meaning that it takes a message and converts it into a fixed string of digits,

also called a message digest.

MIB An acronym for Management Information Base. It is a set of objects that

contain information about the device.

Note that MIB-2 is simply a subordinate component of the overall MIB.

MULTICAST PACKET A packet transmitted to a specified set of nodes on the network.

MVR Multicast VLAN Registration is a method of using a single network-wide

multicast VLAN to transmit common services, such as such as television

channels or video-on-demand, across a service-provider’s network. MVR

simplifies the configuration of multicast services by using a common VLAN

for distribution, while still preserving security and data isolation for

subscribers residing in both the MVR VLAN and other standard or private

VLAN groups.

NETMASK The IPv4 netmask divides a network into logical subnets. This number uses

a binary representation to include or exclude address. For example, these

netmasks correspond to various internet classes:

Class A: 255.0.0.0

Class B: 255.255.0.0

Class C: 255.255.255.0

NETWORK MANAGEMENT

STATION (NMS)

The computer used to run network management software, e.g., ECView.

Messages from ECView are displayed on the NMS.
