Chapter 3 – Network Requirements
The following list is the IP
edge
network characteristics required for a
successful system implementation.
Important!
Toshiba recommends a through network assessment
using Pathview, AppCritical or similar tool. During and
after installation setup network monitoring with a tool
such as What’s up Gold, Solarwinds or, IPSLA.
The following servers must be available to the IP
edge
server.
DNS
- The enterprise name assigned to the primary node must be
registered with the DNS service. Toshiba recommends that the IP
edge
server name(s) be registered with the DNS. If equiped, the IP
edge
Meeting names must be registered with the DNS.
NTP
- A network time protocol service must be assigned to keep the
nodes synchronized. The IP
edge
servers will ship with a default NTP
service pointer (pool.ntp.org). Toshiba recommends that time server pool
be referenced, not a single server.
The Network Time Protocol (NTP) is a protocol for synchronizing the
server clocks on a data network. NTP uses UDP on port 123 as its
transport layer.
