Configuring Network Topology
This section describes how to configure network topology.
26.2.1
Types of IP Network Traffic and Network Subnets
IP network traffic processed and/or generated by the Mediant 8000 may be divided
into the following categories:
Management (OAM) traffic – including SNMP, SSH (CLI) and NTP (time and date
synchronization) protocols
Call Control traffic – including MGCP, MEGACO and SIP protocols
Media traffic – including RTP and RTCP protocols
The IP network on site, where the Mediant 8000 is installed, may be configured to
either pass all types of the IP traffic via the same network segment (the simplest and
default network configuration). Or, alternatively, use different network segments that
are dedicated to the transmission of a specific traffic type.
Each network segment (subnet) has its own address space (e.g. the OAM subnet may
use
10.7.x.x
addresses, while the Control subnet may use
10.8.x.x
addresses). This
requires the Mediant 8000 to have multiple IP addresses – at least one address for
each subnet to which it is connected.
Note:
Some network administrators may use the term
VLAN
instead of
Subnet
to
see the segment of the IP network. These terms are interchangeable.
Subnets may be separated via the following methods:
Physical interface separation
– different Ethernet interfaces (cables) are used
for each subnet.
Quasi-physical separation via use of tagged VLANs
– the same Ethernet
interfaces (cables) are used for transmitting the traffic that belongs to different
subnets; packets are separated via the use of a VLAN tag placed inside the IP
packet header.
