TL1 Agent Datasheet

Rapid prototyping and development tool for building Java-based SNMP agents, TL1 agents, and Multi-protocol agents.

Introduction

AdventNet 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.

AdventNet 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
