Working on the development of the TCP/IP stack(IP layer, Transport Layer, and Application Layer).

Worked on feature enhancements for 4G ENodeB.Worked on PGW and SGW nodes at the Network Side.Good understanding of 4G procedure from UE to Network(End to End).Used tools like Wireshark, postman, Linux development tools, git, Bitbucket, etcPGW/SGW(LTE) :Skills and Technologies used:C,Shell Scripting,TCLOct 2020 - Dec 2020 (Polaris Networks)- Bug Fixed and Improved PGW and SGW nodes. - Provided NetCLI supportfor many SOAP APIs at EPC Side.EPC NETTEST :Skills and Technologies used: TCL Scripting,C,Lexers and Parsers-Written various NETCLI implementations of SOAP APIs. -Written variousTCL scripts for Regression tests, to test EPC Nodes Functionalities. -AlsoSolved a few bugs for NETTEST Console.EPC LOADTESTER(ENODE B + CONSOLE) :+ Front EndSkills and Technologies used: c,c++,Qtcreator,tcl,Rest API, Tcl API,FSM, Shell Scripting- Created many event handlers for ENode B to handle events whilecommunicating with other nodes of EPC.- Fixed incorrect display of Data Traffic Metrics for uplink and downlink data.- Implemented support of Echo Request And Response to observe the pathfailure between PGWs and ENode B Emulator.- Implemented support of Local S1 release for UEs at ENode B Side.- Implemented support of HTTP(s) or HTTP over TLS/SSL at Load TesterConsole to support HTTP(s) communication between LoadTester Consoleand Traffic Generator, where LoadTester has the option to choose differentcertificate and public key file at LoadTester Console .- Enhanced EPC LoadTesterto stimulate large number of CIoT devices.- Written a shell script from scratch to automate LoadTester, NetEPC setupTraffic Generator and NETTEST setup to run Overnight Regression test byautomatically updating all the builds from the repository and storing the result oftest list in a .txt file.- Developed and maintained many Regression test scripts for EPC andLoadTester using TCL scripting.
