Significant Achievements

1. Ciena OnCenter(Onsite – USA for 3 months and then OffShore)

Description

This project is about maintaining and (for new features) developing an NMS system for a leading north american telecom vendor.

The NMS is runs on top of Weblogic, and has support for a variety of network elements, supporting different protocols (SNMP, CORBA, TL1 etc). This is a considerably big product with 1.2 millions + lines of Java code.

Role

Project Leader (with additional responsibility of release coordinator)

Contribution

My job is to 1) estimate when a new feature comes in, 2) design 3) Track the implementation/testing and deliver the features.

I am also responsible for the defects coming in, which I need to assign and track, and in case of very complex ones, help the team solve them.

2. Corvis Network Element Controller (Onsite – USA)

Description

The EC (Element Controller) software runs on the Corvis Network Elements and is used to control and manage those. It provides north bound interface for the NEs using the TL1 protocol. In the backend, it talks to the cards and various components of Network Element using SNMP. Total EC software is divided into two main modules, 1) TL1 agent (C++), and 2) Faultd (Java). I worked on both of them.

3. Corvis Network Manager – Security Module (Onsite – USA)

Description

The CNM (Corvis Network Manager) integrates Corvis Network Elements and provides a single point to control them. This product provides comprehensive management of all aspects of the network. CNM server runs as a java server (RMI-IIOP) and connects / keeps track of the NEs using TL1 protocol. CNM client consists of GUI applications (swing / awt / JSPs / servlets) which provide front end interface for managing the network and network elements. The application itself is pretty big, and it was not built by us from scratch. We actually customized and added on to the Lumos's TMF (Telecom Management Framework).
The CNM interacts with NEs and clients over the network. All the network communication is made secure using SSH. We (2 of us in the security module) researched and discovered a way to secure RMI-IIOP communications over the net using SSH, which has been recommended by our manager to the top management as a possible case for applying a patent.

4. Consultant - Localization & Build (Onsite - USA)

Description

Toshiba is launching a new series of printer in the market. There is a set of applications accompanying the printers which will allow / assist the users to control them.
Those applications are, TopAccess & Top Access composer (JSPs), Printer Drivers and docmon (written in C, show user a GUI on windows).
Localization
All these applications are to be localized for 12 European languages and Japanese, apart from US english in which they are originally built.
Till now, this job of localization used to be carried out manually. The process was time consuming, error prone, and not repeatable.
My responsibility was, to study the way localization is carried out in the different applications listed above, and to suggest ways to make it an fast / easier/ repeatable / less error prone process. Also, to find out the sections which can be automated and automate them.
The cycle of the localization includes,
- Preparation a database of translated strings from the strings already available in each application
- Identification of strings that need to be translated (to be done differently for each application)
- Checking if any of these strings has already got its translations in the database, if not send them for translation
- Once the translations for the strings come back, update the existing database with them
- Update the localized files of the applications with the translated strings
This entire cycle was automated, and web interface was provided for each of these operations.
Build
The end product is packaged and put into a single CD for distribution to customers. This includes drivers/docmon for windows 9x, windows NT for west european languages (which use the same encoding as english), and for east european languages which use a different encoding. To prepare the CD, one has to build the individual components on individual machines, and then transfer the files to a single machine where an install shield script takes care of preparing the CD.
This process was also manual, and I am doing the automation for this as well. This involves controlling processes on different machines. So it uses java RMI to achieve that. The build tool is general purpose, with few changes in the configuration files, it can be used to build any windows based application (which uses msdev / vss etc.)
The build system does the entire task of getting the files corresponding to a particular label from VSS, building them and transfering the built files to the install shield machine. In the front end it uses java swings (for the GUI), in the backend there are many RMI servers running on the actual build machines, which do the actual work.

Role

Consultant.

Contribution

Automated most of the steps involved in the build and localization processes.
Suggested innovative ways to so that the remaining manual operations became less error prone & less time consuming (sometimes more than 10 - 15 times reduction in the cycle time).

6. Customer Control over internet (Onsite – The Netherlands)

Description

In Holland, there are some special telephone numbers. Customers of these numbers can forward a call to a specific phone connection depending on time, or in a round robin method among different numbers. Customer can also change these numbers depending on where he wants to receive these calls. Initially to do all these changes, KPN had a voice response system. Which now they have changed to the internet system - CCI (Customer Control over Internet). It is a web based automation of some facilities which already existed but the interface was through phone (voice response system). So now customer can log into the web and see his settings and change the same. The application uses technologies like servlets, xml (to pass information among different layers of the application), oracle and rmi (its between servlets and business logic) and it talks with another application called SMAS system. SMAS system is the place where the switch is actually implemented. SMAS system does the actual changes to effect the changes done by customer. It is designed in various layers communicating to each other:
1. Front End: servlets communicating to business logic thru RMI
2. Business Logic: is the core of the application, serves the front end, communicates to database and SMAS through interfaces.
3. Database: is oracle on solaris

Role

Project Engineer

Contribution

I was involved in the design, implementation, and installation.
Apart from taking part in design of the business logic, I was the only person working on the front end, responsible for the servlets, xsl sheets, and web server.
