The present scenario
The bandwidth crunches are increasing exponentially and the demand for higher bandwidth is an emergency now. Similarly the need for higher connectivity and the need for which operators today need differentiated and customized services that match end users needs.
Mediation Services
The framework:
One of the primary solutions to the complexity of network management, is to
make it possible for the various software systems speaking in one language (protocol) to
access network elements, or other software systems (OSSs), which were developed to use
another. This is called "mediation," and, in addition to protocol conversion, mediation
involves protocol Syntax validation , verification.
Mediation Frame Work address the problem of seamlessly mediating diverse network management interfaces, solution is the Mediation Frame Work (MFW) that facilitates the development of configurable and scalable solutions for the access, transmission, wireless and switching networks along with the vast array of operational support.
- Mediation FrameWork is a set of software modules Developed by Mediation Team at U&I Facility for converting commands in one management protocol into another protocol or proprietary protocol.
- Implemented Mediation using the ObjectStream mediator.
- Implemented TL1 Agent using
- Lumos TL1 Workshop
- Object Stream
- Implemented SNMP Agent using
- Epilogue
- ObjectStream
TL1:
TL1 is a message based interface used to manage NE s that are deployed for Synchronous Optical Networks (SONET) and other key communication technologies.
(Ex . ATM Networks)
SNMP:
SNMP is a standard TCP/IP Internetwork Management Protocol. It operates on UDP. Primarily used for management of data communication networks. But the scene is changing.
Test Harness Applications:
TL1 TestHarness:
Transaction Language 1 (TL1) is a set of ASCII-based instructions, or "messages," that an operations support system (OSS) uses to manage a network element and its re-sources. TL1 is a widely used management protocol for controlling telecommunications networks through a human understandable instruction set.
The Management entity and the Mediation Services communicate with the
TL1 protocol format over TCP/IP.
This Management module provides the user interface either through
COMMAND LINE OR through the SCRIPT FILES consisting of sequence of TL1
commands. This is also responsible for updating Log files that comprises
of the TL1 Requests, Responses, Acknowledgements and Fault Alarms.
SNMP TestHarness:
SNMP Test Harness is a generic SNMP Manager, which is "WinSNMP compliant" and it supports Level-2 SNMP interaction.
This implies that it supports communications with SNMPv2 agents, in addition to providing full "Level 1" and "Level 0" support that means it provides for….
- SNMP message encoding and decoding.
- Use of target agent addresses and community strings
- Supports the requisite transformations specified in the "Coexistence" document (RFC1452)
- Supports SNMPv2 PDU formats and MIB-2 structure
This SNMP Manager application is used with the SNMP Agent (part of Mediation Services) to test validate it's functionality.
This application ensures…
- Consistent processing for SNMP specific functionality
- Abstraction from the User Interface specific features
- Complete validation for all conditions
- Execution of SNMP command scripts.
- Multiple Log Levels
- Multiple levels of user interaction.
- Well-defined interfaces for Transport provision and client provision
Simulation Software for Network Element:
Auto Generation Utility:
TL1 Test Cases Auto Gen Utility:
The purpose of this exercise is to create a utility that will automatically create Test Script files for the TL1 Harness Application. This process will use Lumos generated files and other TL1 Mediation classes as its source of input. The output will be a set of ASCII text script files that can be loaded in the TL1 Test Harness Application with minimal or no modification.

SpyderWatch - A WebBased Network Management Software
U&I SpyderWatch is Web Based Network Management System Product currently under development at the Bangalore Facility of U & I System Design Ltd. The aim of the software is to provide a generic and extensible network management platform that may be used to manage distributed networks spread across continents by exploiting the global acceptance and connectivity of the Internet.
SpyderWatch is an extremely powerful and very generic Network Management System that uses the Internet messaging backbone to carry out monitoring and control of network services and resources over distributed networks spread across the world.
Features of SpyderWatch
The SpyderWatch system is designed to serve as a network management system and must provide support for standard network management requirements related to control and monitoring of network resources and services.
Besides these standard requirements associated to legacy network management services, SpyderWatch is designed to support various analysis and control features that help the network administrator to get detailed information of the network state from various perspectives.
The extensible platform supported by SpyderWatch provides a greater level of control and insight to the network administrator thus enabling him to perform management tasks more effectively.
SPYDERWATCH is a new approach to managing Internet and Intranet devices and services. SpyderWatch has created a powerful set of integrated tools that is able to easily manage diverse network resources using a Web Browser.
First-generation Web technology dictated using a CGI/HTML solution. However, mimicking a live GUI using a series of forms-based transactions is inadequate. Second-generation Web technology (i.e. Java) promises to export the live GUI through the Web as a dynamically acquired component.
SPYDERWATCH provides the necessary platform required to perform reliable network management from within a Web Browser. These components include Java display applets, SPYDERWATCH core classes, SPYDERWATCH Management Services and the Java Virtual Machine.
