IP Network engineering guidelines
Overview
IP network assessment procedure
553-3001-204 Preliminary 0.10 August 2000
This chapter provides guidelines and recommendations to help plan,
engineer, and test the ITG Line 2.0 card/i2004 Internet Telephone network.
See "Configuration of the DHCP server" on page 97, for engineering
guidelines to set and configure the Dynamic Host Configuration Protocol
(DHCP) server to support the ITG Line 2.0 card and i2004 Internet
Telephone.
An efficient ITG network design begins with an understanding of traffic and
the underlying network that transmits the traffic. The following procedure
summarized the steps the technician must perform to determine the network
requirements of the specific system.
Procedure 1
Network assessment procedure
1
Estimate the amount of traffic that the Meridian 1 will process via the
ITG network. See "Calculate ITG traffic requirements" on page 57.
2
Assess whether the existing corporate intranet can adequately support
voice services. See "Assess WAN link resources" on page 62.
3
Organize the ITG network into "zones" representing different
topographical areas of the network that are separated according to
bandwidth considerations. See "IP Voice zones" on page 64.
4
Set a variety of service parameters to improve service and coordinate
(with the IP administrator) the prioritization of voice packets with data
traffic. See "Set service parameters" on page 69.
5
Decide to use separate subnets, or a single subnet, to carry voice and
management traffic. See "Separate subnet configuration" on page 86.
