Project Details
Project Name: Remote Up-gradation Protocol
Client : In - house Product Development
Project Abstract
Project is to develop a protocol designed to meet the requirement of upgrading the router software and configuring the router from a remote location over the Internet or over the LAN. The protocol is a combination of a server and a client residing in the box and the host machine respectively. Based on the customer requirement to upgrade or configure the box , the client and server communicate to achieve the task. 
Duration 6 Months
Platform IXP 425 Network Processor
RTOS uClinux
Language C
Role Design, Coding and Testing
Responsibilities
- Designed and developed the Client and Server model for the Protocol
- Server is made to run as a daemon in the box and the client resides in the host machine (remote location )
- The entire module has been implemented using (TCP/UDP) Sockets (Code can be changed to work in the kernel mode.) 
- Functional Testing is done.

Project Name: LDSV ( Load and Save )
Client: In - house Product Development
Project Abstract
Load and Save is a module in the router software whose functionality is to save the configuration data of different modules so that when ever the box reboots for various reasons the same data can be loaded into the RAM and the box could resume its normal operation .
Duration 6 Months
Platform IXP 425 Network Processor
RTOS uClinux

Project Name: Embedded HTTP Server
Client: In - house Product Development
Project Abstract
The project is aimed at developing a user friendly interface for the end customer to configure the router. This embedded http server has been developed based on the RFC no 2616.

Duration 8 Months
Platform IXP 425 Network Processor
RTOS uClinux
Language C
Role Design, Coding and Testing
Responsibilities
- Developed the Server as a combination of session maintenance and tag processing modules in accordance with the RFC 2616
- The server is set up in the router box after integrating the two modules, which would now enable the user access html pages for various options. 
The server is duly tested for SOEKRIS and IXP 425 boards

Project Name: Trace and Log
Client: In - house Product Development
Project Abstract
This is a central module in the router which takes the trace statement from the module and displays it to the user whenever the user enables it. All the log statements of a module are stored in a file and displayed whenever user requests.
