Profiles and profile groups

The HX gateway incorporates four major network-management
components within a single high-performance server:
• Element-management server
• Graphical user interface (GUI)
• Back end database
• CACTI
These components enable the HX gateway operator to perform
both network operations (such as monitoring network status and
statistics) and overall network management activities (such as
configuration and control).
NMSS configures satellite routers and some of the HX gateway
components. The network configuration is stored in the UEM
database, and operators can maintain it either through the Vision
graphical user interface (GUI) or provision components using a
batch mode facility. In addition, Vision provides a commissioning
interface to the Web-based auto commissioning system
(WebACS) to support the auto-commissioning of satellite routers.
NMSS generates configuration files for each Vision-managed
gateway component as needed, and sends them to the MFS
component of the NMSS server. The MFS acts as a central
repository for all configuration and software files for
Vision-managed gateway components. Each gateway component
managed by Vision contains a management gateway client
(MGC). MGC is in constant communication with MFS using a
proprietary protocol. the MGC downloads configuration files
from MFS.
NMSS also generates configuration files for remote site
components. It communicates with remote components through a
specialized mechanism called software download (SDL), which
informs the components of changes in required files. The SDL
protocol permits files to be delivered in both push (sent
unilaterally by NMSS) and pull (requested explicitly by the
modem component) modes. In addition, NMSS uses a multicast
delivery mechanism to transmit shared files simultaneously to all
modem components that need them, thereby conserving outroute
bandwidth. Files that are not shared between components are sent
via unicast delivery.
To simplify the task of managing the many different
configuration parameters available in the HX System, NMSS
provides conceptual groupings of related parameters called
