• Project Name : TDL2Yang
• Technical skill: C, yang, python, IOSXE, Miraki Team Size : 3
• Description:
• Creating the yang model for miraki controller dashboard. Features and Role:
• Write the huck for IOSXE OS to convert the yang to TDL layer.
• Interface for the protocol configuration like IP, Route table, ACL etc.
• Write the translation script to generate the transform yang model from TDL file.
• Project Name : IOSXE programable Model generation
• Technical skill: C, Python, Linux, IOSXE, makefile, TDL,TPP, STG. Team Size : 6
• Description:
• Creating the automation tool to create TDL programmable interface for the IOSXE CLI to configure the CISCO products for protocol. Bring up new NGIOS Target with the infra.
• Features and Role:
• Design and implement of the script which create the programmable interface from the input from the IOSXE CLI parser chain.
• Implementation of the runtime translation layer to convert the CLI to TDL table entry and versa for CLI storage.
• Integrating the changes to existing cat9k, c8kv, wlc platform and bring up.
• Challenges was to make automation with the all possible parser macros and build it with
• new NGIOS infra.

• Project Name : IOSXE protocol CLI simulation implementation.
• Technical skill: C, Linux, CLANG, makefile, UNDO, gdb, perf. Team Size : 10
• Description:
• Creating the simulation environment to validate the configuration, like IP, routing table, physical device etc. Objective is the apply all the config in the new defined memory and virtual device and protocol and only config with success will be applied actual controller/router/switch. Features and Role:
• Design and implement the virtual environment and define the boundary function.
• Compiler instrumentation to intercept the memory load/store operation to make sure of not
• to reflect the erroneous value to physical memory, write relevant mock functionality.
• Packaging the new infra to IOSXE OS for build subsystems with new target platforms for
• cat9k switches and c8kv routers.
• Handling the team of large group for guidance and code reviews.
• Project Name : Minimal IOSXE and dynamic Protocol load.
• Technical skill: C, Linux, CLANG, subsystem, gdb Team Size : 6
• Description:
• Existing IOSXE OS package is having huge image size of about 1GB+ and run time memory of about 2.5GB. Objective of this project is to decrease the image size and load the image dynamically on the go with CLI execution.
• Features and Role:
• Image size is reduced to 20MB for launchable minimal IOSXE.
• Run time memory is reduced to about 300MB.
• Challenge was to remove the protocol subsystem like IP, snmp, licence etc intelligently from
• core subsystem to reduce image size and run time memory reduction.

• i) Implementation of multimedia engine (RACE – Robust Automotive Connectivity
• Entertainment)
• Part of a 6 member team which worked on implementing of high-end automotive
• infotainment solution.
• Platform used: freescale imx6x single/dual core.
• Operating System: Linux.
• RACE supports deferent classes of devices like USB, SD, IAP, MTP, CDROM, CDDA for
• the entertainment solution.
• Worked in Device manager. Which will monitor all the device connected to the system using mdev configuration technique (hot plug-in). Multiprocessing environment to communicate between the device manager and media app by monitoring Linux kernel event.
• Implemented database creation for the connected device by reading the device information and file system information. Added support for the browsing device using database.
• Implemented unified view for the connected devices. All the connected devices are treated as one device and browsing and playing support is done.
• Added USB-CD driver support to RACE multimedia engine.
• ii) Part of RACE project traveled to CHINA four times for the technical support for costumers. Worked under intense pressure to solve the issues which are only reproduced at costumer place.
• Solved the Issue in the device connectivity during the endurance test, which is the test undertaken in car for continues five days with connection and disconnection of all kind of devices and continuous playback.
• Added the performance improvement suggested by costumer.
• iii) Implementation of exFAT File system and including new filesystem to VFS (Virtual File
• System) in Linux.
• Part of a 2 member team which worked on implementing the a new file system exFAT
• support to Linux kernel.
• Implemented the specification of the file system operation on the actual device side as specified by the Microsoft. Added the new file system to the VFS in Linux. Since this is the kernel space operation for the Linux managing the memory, CPU, I/O operation one of the major task with the implementation.
