 Carrier-Class
Network Management System for Broadband Wireless Access
Embedded with the entire knowledge base of BWA network operations,
AlvariSTAR is a unique state-of-the-art power multiplier in the hands
of the service provider that enables the provisioning of satisfied
customers. AlvariSTAR dramatically extends the abilities of the
service provider to provide a rich portfolio of services and support
rapid customer base expansion.
AlvariSTAR supports common network management applications in
compliance with TMN standards, providing comprehensive Fault,
Configuration, Performance and Security management functionality:
Fault Management:
AlvariSTAR Fault management capabilities allows for effective fault
detection, isolation, and resolution. Utilizing heartbeat monitoring
and SNMP trap notifications for fault real-time reporting, AlvariSTAR
supports event logging, fault presentation on the map, color-coding
according to fault severity, fault filtering by various attributes,
event correlation and suppression, event forwarding, alarms
acknowledgement, automatic email initialization upon fault detection
and historical event queries.
Configuration Management:
Equipped with comprehensive easy-to-use configuration and provisioning
tools, AlvariSTAR provides for simplified network deployment &
maintenance and enables operators to scale BWA networks to hundreds of
base stations and thousands of terminals. Dividing the network into
logical, hierarchical groups network operators are able perform common
activities on multiple nodes simultaneously, or quickly drill down to
a single device to customize it as desired. Configuration Management
functions include object creation, auto-discovery of new or changed
equipment, multiple network-element configuration, and inventory
management. AlvariSTAR supports efficient software upgrade management
for multiple network elements, including scheduled execution (to
manage busy hours), automatic invocation of the device oriented
operations (such as boot from shadow) and automatic handling of
upgrade failures.
Network View:
AlvariSTAR offer comprehensive network view, with Geographical
Topology (providing visual representation of the placement of managed
network elements, with multi zoom levels from regional network views
down to NE), Logical Topology (for visual representation of the links,
interdependencies, and relationships among network devices) and
Physical Topology (for visual representation of the actual device and
any components residing inside). Various locations can be managed by
regions, cells, and sectors. Devices are either automatically or
manually associated to locations during the discovery phase.
Service Management:
AlvariSTAR support service policy management by managing Service
Profiles (containing all configuration parameters for a particular
service) according to operator’s service policy. AlvariSTAR supports
instant provisioning of subscriber’s services based on these Service
Profiles. The option for complete service provisioning prior to CPE
installation allows significant reduction of installation overhead,
with service automatically activated once the CPE is installed &
authenticated.
Performance Monitoring:
AlvariSTAR supports real-time monitoring, as well as scheduled
collection of over-the-air traffic load statistics, wireless link
performance data and quality of service statistics. AlvariSTAR’s
performance collection engine helps to identify problems and
bottlenecks and optimize resource usage.
Security Management:
AlvariSTAR secures itself from unauthorized user through
implementation of multi-level access authorization. AlvariSTAR allows
network administrator to manage users and user groups, to associate
system functions with individual users or groups (functional
permissions) and to restrict user permissions according to location
(location based security).
System architecture
AlvariSTAR is a multi-layer architecture application comprising the
following:
- Infrastructure Layer, providing
common functionality including inventory, faults, topology, log and
reports, software download, performance data collection and
monitoring, and security.
- Device Driver(s) Layer, enabling
the addition management, configuration and service provisioning
capabilities that may differ among the various product lines. One or
more Device Drivers can be integrated into the Infrastructure Layer.
The AlvariSTAR system is comprised of
the following components:
- Application Server, coordinating
the interactions among all system components and communicating with
managed sub-systems and network devices. The Application Server uses
highly scalable RMI (Remote Method Invocation) protocols to ensure
simple and reliable communication among system elements.
- Mediation Agent(s) that runs
continuously in the background providing services for communication
with external systems and devices using various protocols. The
Mediation server includes a mediation mapper for Alvarion devices’
MIBs.
- Database that enables the storage
of network and business objects such as devices, device
configuration, links, locations, alarms, events, performance data
and system logs. The Database Server enables the storage and
retrieval of data required by the users. Supports a built in Versant
DB for small deployments and Oracle DB for large deployments.
- GUI Client, a graphical end-user
application that allows users to access the AlvariSTAR management
information and processes, according to specific user’s access and
functional permissions.
The system’s components are designed
to support a variety of system architectures, starting from the
minimal “All-in-One” system where all components reside on the same
computer, through entry-level systems with several remote Clients, to
a fully distributed system. This allows for maximum flexibility
enabling easy changes throughout the life cycle of the system,
supporting pay-as-you-grow strategy and on-the-fly system expansion
and architecture changes. |
