WebNMS TL1 API offers a set of Java libraries for development
of Java and Web-based solutions for managing TL1 (Transaction Language
1) based telecommunications infrastructure. The Java based WebNMS
TL1 API is a comprehensive development environment packed with TL1
protocol stack and TL1 message parser, for building network management
applications.
WebNMS TL1 API Architecture
The WebNMS TL1 API consists of layers of APIs that can be used
at different levels of application development based on requirements.
The low-level application can be developed using the basic APIs:
Low Level APIs. The Low Level API consists of 'Communication API'
module that provides the interface for application development.
It communicates with the underlying protocol through the 'Transport
Provider' module. The TL1 messages (input, response, autonomous,
and acknowledgement) are parsed and handled by the 'TL1 Parser'
and 'Message Objects' modules respectively. All the log messages
are handled by the 'Logger' module and redirected to the Log files.
The High Level API provides access to the TL1 message definitions
(meta data) and the actual TL1 messages present in the Command Set
and Data Set files respectively.The Tree Components and Utility
Classes provide the interfaces to represent the data in the GUI
applications. The GUI based Management application is built using
these High Level API.
Some of the significant modules in the architecture
are explained in detail below.
Communication API: The Communication block forms the
core of the product providing an entry for applications to setup
communication mechanism, send messages to the TL1 device, and
get responses. It also offers complete session management functionality
that helps applications to interact simply with the data hiding
the underlying communication channel and protocol complexities.
The WebNMS TL1 API also allows simultaneous communication with
multiple devices.
Transport Provider: The Transport block is designed to
be protocol-neutral accommodating transport protocols as plug-ins.
This way, the core API do not perform operations specific to any
particular protocol.
TL1 Parser: The TL1 Parser block enables management applications
to flexibly recognize and process different types of TL1 messages
and check them for Bellcore GR-831 standard compliance. The parser
then generates message objects, which can be used by applications
for additional processing.
Apart from the core TL1 API libraries, WebNMS
TL1 API also offers useful TL1 tools. These tools can be re-branded
and bundled as part of the management application developed over
WebNMS TL1 API.
TL1 Craft Interface: TL1 Craft Interface is a user-friendly
GUI tool that enables craft operators to easily manage the TL1
infrastructure. It helps lab technicians and field engineers to
test, monitor, administer, and provision multiple TL1 agents.
This tool offers a sophisticated and productive environment and
can manage TL1 devices from different equipment vendors.
TL1 Message Builder: TL1 Message Builder is a user-friendly
GUI tool to build XML-based TL1 message definitions and pre-built
TL1 commands. These message definitions play a crucial role in
automating various TL1 operations. The TL1 message definitions
/ metadata are defined in a command set file and pre-built TL1
commands are defined in a data set file.
Building TL1 Management Applications: Using WebNMS TL1
API
Building management applications using WebNMS TL1 API is easier
and elegant than ever before. It offers a rich set of features and
enables development of high quality TL1 management application with
reduced development time and time-to-market. The Java TL1 API libraries
are designed to deliver high performance, scalability, robustness,
and usability. WebNMS TL1 API with its smart TL1 protocol stack
and TL1 message parser facilitates efficient handling of various
TL1 message formats.
Using WebNMS TL1 API, our customers have successfully built
OSMINE compliant EMSs that have been integrated with popular (Telcordia
compliant) OSSs, such as NMA, TIRKs, etc.
