eNM LightSoft enables you to manage network elements at multiple levels. To
achieve this, eNM LightSoft distinguishes between the network elements (or
managed elements) that make up the network and the logical or functional
nodes (FNs) that these managed elements (MEs) represent. For example, in
eNM LightSoft, an ME designates a piece of equipment, such as a shelf, and an
FN represents a functional element of the network, such as a port.
This unique distinction enables true multidimensional network management by
allowing operators to:
♦
Focus on MEs when creating and deleting NEs (physical layer)
♦
Focus separately on the ports available at each technology level (for example,
SDH/SONET, optical, or data) when managing trails (technology layer)
Whenever an ME is added to the network at the physical layer of eNM LightSoft, an
FN is projected automatically into the relevant technology layer, as reflected in the
topology view in the interface. If an ME contains ports that belong to multiple
technologies, as is the case with XDM shelves, FNs are created at each technology
layer containing only those ports relevant to that layer.
6.4.4 Trail Configuration
eNM LightSoft provides powerful trail configuration tools. A detailed definition of
through and local cross-connects gives administrators precise control of the system
structure, guaranteeing uninterrupted services and maximized use of bandwidth. In
addition to manual trail routing, the patent-pending path-finding algorithm searches
for and selects optimal end-to-end primary and protection paths across complex
topologies. Optimization criteria are user-defined and may include such parameters
as number of nodes, link cost, distance, shared risk (such as common ducts), and so
on. A powerful trail synchronization function polls the entire network, keeping the
eNM LightSoft trail database up to date. eNM LightSoft also provides numerous
protection and traffic reconfiguration schemes in case of service disruption. The
system provides full traffic restoration via contingency traffic plans.
The eNM LightSoft advanced trail management functions enable you to create,
delete, and modify both SDH/SONET and optical trails.
SDH/SONET Trail Management
For XDM NEs, eNM LightSoft supports both virtual and contiguous concatenation
for the transport and cross-connection of VC-4/STS-3c signals. This is used for
high-bitrate data services that require transport of payloads exceeding a single
VC-4/STS-3c capacity.
