3.1.3 The Domain Server
An Access Domain is a logical network handled by a management system
and defined by approved IP addresses. The components in an Access
Domain are managed by a Public Ethernet Management (PEM) system
through a Domain Server.
As shown in Figure 6 on page 12 the Domain Server is physically located in
the Access Domain or on the Management Server, but for an EAN, which is
shown to the right in Figure 6 on page 12, the Domain Server function is
integrated in the ECN330/ECN320 controller node.
The Domain Server comprises a DHCP server, a Domain File Server, an
NTP Server, PEM Domain Services, and HPOV clients.
