WebNMS Management Framework Architecture and Features
WebNMS Management Framework is architected to support varying deployment
needs ranging from a single server to multi server deployment
Architectural highlights include:
- Data persistence using RDBMS , providing for data integrity
and security
- Multi-Tier Open Framework facilitating load sharing and failover
- Support for using replicated or clustered databases
- Stateless, Loosely Coupled Architecture with XML messaging
- Thin and Rich Clients
High Availability - Multi-server deployment
The WebNMS Management Framework server consists of three tiers of server
components, the management server (mediation) tier, which provides
protocol mediation with the managed systems, the back-end server
tier, which provides database transaction and encapsulation service
and the front-end server tier, which provides client session management
services.
Further Distributed Mediation Servers can be deployed for massive
scalability by distributing the network facing functions across
multiple Distributed Mediation Servers. These servers support management
of large networks, achieving scalability on both the size of the
networks and systems that can be managed.
There can be more than one deployment of each of these servers
to achieve massive scalability. The servers can be deployed with
redundancy so that any failure, results in failover to other server
components.
This feature is crucial in high-availability applications.
Hierarchical Remote Management
WebNMS Management Framework supports distributed server deployment. Distributed
Mediation Servers can be deployed in regional offices and a central
server can be deployed at the NOC.
This deployment flexibility is particularly suited to geo-graphically
dispersed deployments with a need for
remote management as well as centralized control.
The Distributed Mediation Server can effectively stream-line information
flow with support for correlation, consoli-dation, buffering and
propagation.
Regional servers can function behind proxy servers and firewalls
with robust communication to NOC servers. XML over HTTP or XML over
TCP can be used depending on the geographical distribution.
Persistent Data Model
High availability for managed services and operational support
is achieved through a persistent RDBMS data model. WebNMS FrameWork leverages the benefits of replicated and clustered databases,
transaction support, database synchronization and object locking.
The database Tier in the WebNMS Management Framework architecture incorpo-rates
persistent data management support with failover capability.
WebNMS Management Framework offers seamless integration with Oracle, Sybase,
MySQL, SQL Server, Solid, Timesten and other popular databases.
