2 Networking Concepts
Planning a network or internetwork (collection of networks) is an
important process that must be done with care to ensure that the
network meets the needs of your organization. Many factors must be
taken into consideration when planning the network or internetwork:
for example, volume of usage over particular links, volume of CPU
usage of each node, physical layout needs and limitations (such as
geographical distances), and desirability of connections to
non-NS 3000/iX nodes.
This chapter provides information to help you design your network and
plan for configuration using NMMGR. The following network design
elements are discussed:
• Design considerations of the network environment
• Network interface and link types
• Subnetworks
• Internetworks
• Address resolution methods:
— Domain names
— Network directory
— Probe and probe proxy
— Address Resolution Protocol (ARP)
