WORK EXPERIENCE
Research Developer at USC Information Sciences Institute May 2016 – December 2016
1) TCP Extended Data Offset (TCP EDO) in Linux and FreeBSD kernel
 Engineered a version of TCP that can add additional space for option, previously limited to 40 bytes
 Implemented Junk option to test the access to the TCP options in the header and the limitation of its length
 Modified TCP header to recognize and process/ignore the EDO option request during the handshaking process
 Introduced routines in the Established state to increase the data offset to a length specified in the EDO option
2) UDP Options in Linux and FreeBSD kernel
 Engineered a version of UDP to carry options similar to TCP but at the tail instead of that in the header
 Formulateda technique using the difference in UDP’s datagram & IP’spacket length to identify the use of UDP options
Course Grader for Internet & Cloud Computing (EE 542) August 2016 – December 2016
Graduate Engineer Trainee at Lodha Group, Mumbai July 2014 – March 2015
ACADEMIC PROJECTS
Custom Network Protocol Present
 Designed a protocol with custom packet format, for data exchange between end systems connected by custom routers
 Implemented the protocol to support UDP/TCP-like functionality and built a custom application for file transfer
Custom Software IP Router September 2016 – October 2016
 Implemented a custom IP router in user space that listens to all its interfaces and captures the IP packets
 Designed the control unit of the router to determine & send packets to the next hop & generate ICMP packet, on error
Linux Kernel Hacking August 2016 – September 2016
 Modified the TCP kernel to increase the throughput of file transfer on a high latency link with heavy losses
 Adjusted the congestion control algorithm and parameters used to allow TCP to transmit on a link where SCP &SFTP stalls
 Achieved 10Mbps throughput to transfer a 2GB file on a 100 Mbps, 20% loss network with a latency of 200 msec
Custom Fast and Reliable File Transfer Protocol August 2016 – September 2016
 Designed and Implemented FTP over UDP using sequence numbers, acknowledgements & retransmission logic
 Achieved 47 Mbps to transfer 2GB file on a 100 Mbps, 20% loss network with a latency of 200 msec (whereas FTP stalls)
 Achieved 78 Mbps to transfer 2 GB file on 100 Mbps 1% loss network with a latency of 10 msec
 Ensured integrity and reliability using MD5 hash values of received and original files
Software Defined Network (SDN) March 2016 – April 2016
 Implemented POX controller for functionalities of L2 learning switch, L2 Flow Accelerated Switch and L3 learning Switch
with Flow Tables for different network configurations using Mininet
 Simulated realistic Virtual Networkson a single Machine and examined the packet flow in the network
Weenix Kernel, Implementation February 2016 – April 2016
 Developed parts of UNIX based Weenix kernel from scratch in C
 Implemented Bootstrap, FIFO process based scheduler and mutex for thread synchronization
 Developed system calls for handling files and directories, such as read, write, open, mkdir etc
 Designed Virtual Memory with copy-on write, page fault handling, memory mapped files and stack management
Token Bucket Emulation using Multithreading and Doubly Linked Circular Lists January 2016 – February 2016
 Simulated a time driven traffic shaper that transmitspackets controlled by a token bucket filter using POSIX threads in C
 Attained synchronization between four threads & handled user’s interruptsto the emulation
NON ACADEMIC PROJECTS
 Web chat implemented by socket programming, multithreading in Python
 Unix Socket Programming to exchange information and build a network topology between nodes in a network in C
 Testing & Evaluation of AWS using Intel Hibench Benchmark Suite, Elastic Map Reduce and ec2 scaling techniques
