Project Details:
Data Protection Appliance
Jan 2007 - Oct 2007
Client: nCipher Corporation Ltd
Description:
The Data protection appliance is aimed at providing highly available
appliance providing support for cryptographic operations from client
applications across the networking. There were two types of appliances
Management appliance and Offload appliance. Management appliance provide
additional user interface that allows the administration of the whole
system from a single interface
Roles: Design, development, QA
Responsibilities:
Involved in design and development of Failover module using C++ under
Linux in the data protection appliance. The failover module takes care of
providing the continuous availability of cryptographic services to the
client even if one or more appliances fail
Involved in the design and development of Configuration Manager module
using C++ under Linux. This module faciliates the configuration of the
system through UI.
Involved in design, development and testing of Resource Monitor module
using Perl. The resource monitor periodically monitors the software and
hardware resources in the appliance and raises an alarm in case of failure
of critical module.
Involved in Unit Testing for the above modules.
Involved in code analysis of Wackamole(Application for high availability)
to find the logic behind allocation of Virtual IP address among the
appliances in the cluster
Involved in code change of Wackamole to allocate the virtual IP address
according to the need raised in the project
Used the design tool Microsoft Visio
Used the debugging tool strace (system call tracer) during the code
analysis of wackamole
Involved in simulating and testing various failover scenarios and hence the
high availability of the cluster using the tools Wackamole and Spread
Mentored the team members on testing the high availability and the code
analysis of wackamole.
Environment: Linux, C, C++, Microsoft Visio, gdb, strace, CVS
XC - Software Sustenance
Mar 2004 - Aug 2006
Client: Motorola Inc.
Description:
The SuperCell Transcoder SubSystem (XC) is the component of RAN - Base
Station Controller in the CDMA Cellular Network. This component is
responsible for
Call processing i.e. Call setup, Data transfer and Call Release
Vocoding i.e. Conversion of data rate from 16 kbps to 64 kbps or vice
versa
Conversion from voice call to packet data call or vice versa
Roles: Design, Development, QA
Responsibilities:
Involved in the module which deals with the call processing of various call
types like voice calls, data calls and packet data calls. This module is
responsible for the call setup, call release, maintaining the session, data
transfer in both uplink and downlink direction and finally releasing the
call for all call types
Have done the requirement analysis, design, implementation, code review and
testing of various enhancement features in the area of call processing
using C/C++ under Unix
Have done implementation and testing of many change requests
Assisted the QA team to solve several issues.
Got a good understanding of the system design in which the call flow is
triggered in the state machine based on protocol events.
Involved in Unit/Integration Testing during which I wrote test scripts in
Expect for the automation of testing
Involved in Bug - Fixing activities in which I solved issues right from the
analyzing the logs using tools like ethereal.
Used the tool Rational ClearQuest for tracking changes due to new feature
development / change requests
Analyzed various logs like sniffer logs, event logs, CAIT logs and various
other logs internal to the module and I have reached a comfort level in
analyzing the logs
Involved in several enhancement feature work in which I have prepared SWFS,
Design documents, Test Plan and some other deliverable documents.
Involved in the module Switch Manager(SM) that is responsible for
allocating/de-allocating the resources by maintaining the status of
resources in the transcoder during Call Setup/Release.
Did the code analysis of Switch Manager module to understand the
functionality and working of this module and took the primary
responsibility of this module.
Solved many critical issues in this module.
Involved in development and testing for enhancement of this module
Mentored the new team members in this module
Developed a testing tool which can simulate any external entity and send /
Receive messages. This tool also has the intelligence to decide whether the
particular test case passed or not. With the help of this tool, entire
testing environment can be simulated and testing can be done automatically
with out manual intervention
Designed and developed a unix shell script to download the source code
files of the transcoder subsystem from the server system to the client
Worked in other modules also (like OAM and platform) to get the bigger
picture of the call processing functionality.
Gave field support to some critical issues.
Have interacted with clients in mails and teleconference whenever the need
raised.
Environment: Unix, C, C++, gdb, Rational ClearQuest, Clearcase
Ethereal dissector
Feb 2006 - May 2006
Description:
Ethereal is a GUI network protocol analyzer. It lets the user to
interactively browse packet data from a live network or from a previously
saved capture file. An ethereal dissector is a parser/decoder that can be
written for a particular protocol and can be integrated to ethereal.
Roles: Design, Development, Testing
Responsibilities:
Involved in developing 1x CDMA EVDO IOS signaling plane protocol dissector
for all the IOS interface as per the 3GPP2 Release - A standard. These
dissector libraries can be plugged easily with both UNIX and Window's
version of Ethereal and compliant to Release - A version of A13, A14, A15
interface messages
Used the Ethereal tool to capture packet data
Involved in unit testing of the plugin dissector
Tested the plugin dissector with the data captured using ethereal.
Environment: Unix, C, gdb, Ethereal
Nokia terminal SMS scheduler
Sep 2003 - Mar 2004
Description:
This application is used to send and receive messages via GSM modem
connected to the system through serial port. The project was aimed at
sending SMS alert to the subscribed users on reception of a new email.
Roles: Development, QA
Responsibilities:
Involved development of feature with C++ under Windows which identifies if
the user is subscribed to receive the email alert and sending SMS alert to
the user on reception of a new email.
Involved in writing SQL scripts which queries the database for new users,
number of users, number of emails and so on
Involved in Log analysis and bug fixing activities for this project.
Involved in testing the feature by sending SMS alerts for the terminals
which were subscribed for testing purpose
Involved in GUI development.
Involved in load testing by sending bulk of SMS alerts.
Environment: Windows, C++, SQL scripts, Visual Studio Debugger
Duration modeling for Text-to-Speech synthesis systems
May 2003 - Sep 2003
Description:
This project is aimed at developing a duration model of phonemes
corresponding to Indian English Language with new features for text-to-
speech synthesis(TTS) systems. The speech synthesized using this duration
model has been found to be improved in naturalness over that of existing
TTS systems.
Roles: Development, Testing
Responsibilities:
Involved in development of duration model of phonemes for TTS systems.
Involved in unit testing of the feature.
Involved in testing the naturalness of speech by changing the duration of
phonemes.
