TL1 Agent Datasheet

Introduction

WebNMS SNMP Agent Toolkit Java Edition is a productive development environment for building Java-based TL1 agents. TL1 is most widely used protocol in telecom devices and deployed applications. TL1 support is critical for telecom device / application management. OEM vendors, enterprises, middleware ISVs, and service providers need TL1 agent for their applications / devices that needs to be managed via standard network management consoles.

WebNMS Agent Toolkit Java Edition's integrated agent development environment offers standards-based, highly developer productive, and proven platform to build TL1 agents with reduced agent development cycle time.

Key Features

• Conformance to Bellcore GR 831, 815, and TR 835 standards. Implementation of Provisioning Messages from GR199.
  
• Security feature with rich set of security options implemented as per the GR 815 and TR 835 standards.
  
• TL1 Northbound interface
  
• Asynchronous Message Processing for faster dispatch of requests.
  
• Delayed Activation Support enabling queuing of input messages in Network Element (NE) for final execution after specified delay time.
  
• Built-in commands support offering greater control.
  
• Transport Provider Interface support to plug in any transport protocol.
  
• Self-Monitoring support to monitor the Agent details, such as the number of requests received, number of responses and autonomous messages sent, etc.
  
• Persistence storage support for storage of non-volatile information in the TL1 Java agent.
  
• Pre-defined command set file with all the commands in GR 833.

Developer Benefits

Agent Development Environment: Enhanced and integrated tools reduce the time to develop TL1 agent, increases developer productivity, and offers reduced time-to-market.

Standards-based Architecture: Built on standard TL1 and XML protocol. It offers a viable platform for integration with any standard management console.

TL1 Agent Development Experience

Agent Toolkit offers a complete TL1 Agent Development Cycle

• Developers can create and edit command set files with TL1 Message Builder.
• Generate agent stub files (from command set file) using TL1 Compiler. The TL1 agent framework can be instrumented to suit device-specific or application-specific requirements.
• Compile TL1 agent after instrumentation.
• Test and verify the developed TL1 agent using TL1 Browser or any other TL1 manager.

The following diagram illustrates the steps in agent development cycle:

TL1 Agent Runtime Architecture:

The TL1 agent runtime architecture explains the components and their functions.

TL1 Agent Components

Transport Provider: Establishes communication between agent and TL1 manager, receiving the request from the manager and forwarding it for processing.

Security: The incoming requests are validated to check authenticity before continuing further processing. Unauthenticated requests are dropped.

Message Processing: It parses the manager request. It maintains references of all the command code listeners, which process the TL1 input messages.

Agent Stubs: Files are generated for users to perform their application-specific or device-specific agent instrumentation
