Chapter 17

VoIP

(voice over internet protocol) devices convert analog telephone signals into digital IP packets

Devices that will factor into the IP addressing scheme include

-End user devices - The number and type of connection -Servers and peripherals devices -Intermediary devices including switches and access points

Capabilities list

For example, whether a specific device is a Layer 2 switch or a Layer 3 switch

What is necessary to plan and use when implementing a network?

IP addressing Scheme

IP Telephony

IP phone performs voice-to-IP conversion with the use of a dedicated server for call control and signaling

Device inventory

List of devices that use or comprise the network

-Layer 3 switching -Network Address Translation (NAT) -Dynamic Host Configuration Protocol (DHCP) -Security -Quality of service (QoS) -Voice over IP (VoIP)

Network devices operating systems that can support the organizations requirements

Network documentation

Physical and logical topology

Traffic analysis

Protocols, applications, and services and their respective traffic requirements should be documented

What mechanism can be implemented in a small network to help minimize network latency for real-time streaming applications?

QoS

Which two network protocols are used to establish a remote access network connection to a device?

SSH and Telnet

Platform

The hardware platform of the device

Address list

Up to one network layer address for each protocol supported

All hosts and devices within an internetwork must have...

a unique address

What are two forms of software programs or processes that provide access to the network?

application layer service and network application

Which elements are required to scale to a larger network?

budget and network documentation

Device identifiers

configured host name of a switch, router, or other device

Network device
