NEM Architecture
Basic components
Core
FOXMAN‑UN is built around a database. This database stores all the relevant information concerning configuration and alarms at the element level. The core component contains the software necessary for managing this information as well as for handling the communication with the other processes.
Agent
The agent handles the communications with the network elements. Several agent processes can be running depending on the number of sub-networks connected to the workstation.
The agent can
− upload and download configurations from and to the network elements,
− poll network elements for alarms,
− retrieve and set status information.
NEM Desktop
The NEM Desktop is the control panel from where all NEM functions can be started. This includes the applications NEM Network Browser, NEM Configurator, and the Networking Package.
NEM Network Browser
The NEM Network Browser provides the operator with a graphical view of the network in the form of maps to supervise the network and carry out the day to day management of the network elements.
NEM Configurator
The NEM Configurator allows setting up all the details of the management network and defining the security aspects. In addition it provides access to the NE configuration management and limited access to the fault management.
Section Management
The Section Management allows creation, modification or deletion of section(s), and launch of the NP GUI for the specific section. The dialog likewise displays all sections of the managed network, regardless of any map that may be opened. It allows creation or deletion of section(s)
Networking Package
The Networking Package provides an end-to-end TDM (SDH/PDH) provisioning of circuits and trails across FOX51x or FOX61x networks.
Ethernet Networking Package
The Ethernet Networking Package allows you to configure, provision, and manage MPLS-TP services.
Ethernet Security Manager
The Ethernet Security Manager provides the user interface for setting up security related network functions such as encrypted transmission.
Service Manager
The Service Supervision and Reporting allows end-to-end network services monitoring. It runs regular reports regarding end-to-end service availability, particularly related to any Service Level Agreements that may exist.
Circuit Emulation Manager (CEM)
The Circuit Emulation allows you th manage all circuit emulation related services. This includes teleprotection services that use circuit emulation.
North Bound Interfaces
FOXMAN‑UN offers a northbound SNMP interface for fault management.
