Responsibilities: Reproducing issue, narrow downing bug, localisation in code, fixing and verification.
Duration and location : 3 years and 11 months ( in parallel with other projects ) : TeamF1
Networks, Hyderabad (Development centre of D-Link)
Tools, OS and Languages: syslog, printk, kgdb, wireshark, tcpdump :
Linux (user space and kernel space) : C
5. Project Name: FVS318Gv2 kernel, user space porting, component integration,
customization and debugging
Project Description:
1. It was a new router and work was to make it a router by making the bsp, kernel, driver,
userspace daemon up and running.
2. It included basic BSP validation.
3. Applying patches of kernel and changes in vanilla kernel and fixing compilation error. Then
doing basic sanity manually that that driver or kernel sub system is working or not, etc.
4. Integration/customization/debugging of user space components required by the customer.
5. Sub projects specific to FVS318Gv2 :
1. Firmware header validation
2. External Authentication using RADIUS C API
Responsibilities:
● I Took a reference project and modified and customized it according to the new hardware.
This includes kernel porting and then component level customization and debugging.
● Dev acceptance test.
● Firmware header validation : written code in c to read firmware as ascii file and reading
product ID in header and matching with device product ID and then only allowing flashing
firmware.
● External Authentication using RADIUS C API : wrote c code to authenticate user with
external RADIUS server.
Duration and location : 1+ years : TeamF1 Networks, Hyderabad (Development centre of D-Link)
Tools, OS and Languages: Gmake, arm toolchain, autotools : Linux : Bash Script, Make script

4. Project Name: IPv6 integration and implementation
Project Description:
◦ IPv6 was an enhancement request by customer and all routers had only IPv4. After this
enhancement router became capable of IPv6 and IPv4.
◦ L5/Application layer requirement was integration of DHCPv6 server and RADVD for
LAN. And DHCPSv6 for WAN as ISP connection type.
● L4/Socket layer work was add/upgrade existing code written only for AF_INET to
AF_INET6. Some address and subnet validation was needed to make configuration
user friendly.
● L3/Routing layer was mostly used in debugging and mostly theoretical analysis.
● Sub projects:
◦ nslookup implementation in C
◦ SMTP client implementation in C
◦ Learning IPv6 and implementing in linux kernel and userspace.
◦ DHCPv6 and RADVD debugging.
◦ upgrading IPv4 socket to Ipv4/IPv6 or writing similar IPv6 socket code.
◦ Analyzing functionality of these datagram in routing, multicasting and neighbour discovery.
◦ nslookup implementation in C : using getaddrinfo, getnameinfo functions, AF_UNSPEC
and sockaddr_storage implemented nslookup as the busybox nslook had problem.
◦ SMTP client implementation in C : implemeted SMTP client with the help of socket API.
Duration and location : 2+ Years : TeamF1 Networks, Hyderabad (Development centre of D-Link)
Tools, OS and Languages : Socket library, DHCPv6, RADVD : Linux : C

3. Project Name: CLI ( Command Line Interface)
Project Description:
● Command Line interface is needed to provide a telnet based console to user, so that
user can get friendly commands options grouped (like wan, lan, firewall, etc).
● Work included to write commands like “net wan static ip address <input>” in XML file.
● Writing a business logic handler in Lua to validate and show error message and at
last save the user input in permanent database, so on next reboot user will not have
to configure it every time.
● Writing/modifying database handler and these handler written in C can interact with other
process and with kernel to start a daemon/process and enable/disable some feature
in kernel or insert modules.
● Designing and implementing business logic and creating/modifying SQL schema
accordingly.
● Adding commands in group and structured way in XML to make the router configuration
easy for user.
● Writing management code for business logic in lua
● Adding/modifying SQL table handler (C language functions) and with IPC mechanism like
pipe, FIFO, exec, system, sockets, ioctl, sysctl configuring/starting/restarting daemons like
http, snmp, dhcp, 802.11, route, etc.
Duration and location : 6 Months : TeamF1 Networks, Hyderabad (Development centre of D-Link)

2. PGD Project Name: OpenCV based monitoring system
Project Description:
● It was Post Graduation project in which we (5 Engineer) worked to create a public
surveillance with the help of web-cam and OpenCV.
● It was counting the total people entered by detecting the face in one frame all the time at
gate of a public place like mall, hotel, etc.
● Learning OpenCV, exploring its API
● Implementing a people counter I.e. Person(s) has to be detected by face or another way
(OpenCV API) and count has to be displayed on monitor..
Duration and location : 2 Months : CDAC Hyderabad

1. BE Project Name: SMS Database in Symbian
Project Description:
● It was a final year project and it was working on application level writing some
management code in python.
● It was creating a dbms system for SMS inbox. i.e. Create a database of SMS inbox then
search and show according to keywords like phone number or person name or date
or combination of these.
Responsibilities:
● Learning Symbian Framework, Python language, PyS60 API
● Writing code to access mobile's SMS and reading each SMS and creating a database.
Take some user's input like name or phone no then generate a db query and execute using
python and return the desired result with some GUI API.
Duration and location : 8 months : Apeejay College of Engg, Gurgaon
Tools, OS and Languages: PyS60 : Symbian : Python
