Network Element Configuration is a configuration management tool that supports both
VLAN configuration and Load balancing configuration on switch using a single user interface.
Server Load Balancing is a technology that maps one logical server connection to multiple
physical servers. It is based on associations between real servers and virtual servers. The real
servers are application servers. The virtual servers have one or more virtual IP addresses (VIPs).
A real server is associated with a virtual server by binding TCP/UDP ports on the real servers
with TCP/UDP ports on the virtual server. When a client sends a TCP/UDP request for a port on
the virtual server, the Load Balancer sends the client’s request to the real server. The client is
unaware of the real servers behind the virtual server but does experience enhanced throughput
and availability for TCP/UDP services. Network Element Configuration is a configuration
management product that supports the various configurations in switch like VLAN and Load
Balancing without bothering about the specification differences of each switch.
This project involved developing the following modules:
 Network Element Configuration - View
It is a program that provides the GUI of the product. It creates network
configuration information and displays it.
 Network Element Configuration - Manager
It is the manager program of the product. The configuration information setup in
the switch is stored in the DB. It executes the display, setup etc. of network
configuration information.
 Network Element Configuration - Adaptor
It is a program that sets the configuration information for VLANs and Load
Balancer in the respective switches.
Module (1)
Network Element Configuration – Manager (until Aug 2004)
The manager module was developed in C++, using platform independent library
(Hitachi's Library). In Windows, the program runs as a multithreaded Windows Service, which
communicates with multiple Views and Adaptors and updates the configuration information
acquired from the adaptor.
Module (2)
Network Element Configuration – View (till date)
The View is a front end Graphical User Interface through which the user can set the
configuration parameters of switch. It is a multithreaded application, which communicates with the
Manager and acquires the information stored in the Manager’s database.
Responsibilities:
 Database Schema Design.
 Design: UML Diagrams (Class, Sequence Diagrams).
 Coding (Parsing and Creating Protocol Data Unit (PDU) structures)
 Preparation of Unit Test cases and System Test cases.
 Unit, Integration and System testing.
 Debugging

Automatic Installation Tool (AIT) is a comprehensive tool used for creation and play back
of recorder files that help facilitate remote installation through the AIT Script Language. The
project involved providing a Windows hooking functionality to capture system messages, recorder
functionality to recognize user actions, development of a GUI Editor for the script, a set of Win32
wrapper APIs to be used in the script and the custom script language. This product is meant to
interface with Distribution Manager (Hitachi's product) and perform installation actions on remote
systems.
Module (s)
Script Analyzer, Script Language and API Development

Script Analyzer
The Script analyzer verifies the format of the script file and does syntax and
semantic checks for the script file.

Script Language
The Automatic Installation Tool's script language was designed to enable the
user to write scripts for recording and playback of events, for performing registry
operations, file operation, directory operations that are required during an installation
process. It was designed to be simple enough for the programmers to quickly adapt to
this scripting language.

API Development
Enables the AIT execution engine to give inputs to the installable software during
the installation process. These APIs shall be implemented in a DLL to enable
expandability of functionality in future. The script execution engine shall invoke these
APIs at the time of execution. AIT execution engine is equivalent to the execution engine
of Rational Visual Test (Remote Installation Software).
Responsibilities:
 Design/Coding of the following components in Script Analyzer
 Lexical Analyzer – Flex was used to generate lexical analyzer code
 Parser – Bison was used to generate parser code
 Symbol Table
 Abstract Syntax Tree
 Semantic Checker
 Design and Development of Script language.
 Coding of APIs with respect to File, Registry Operations and Error Handling
 Testing and Debugging of Script language and the interpreter

Abstract
During the last few years we have witnessed an explosive growth in the
development and deployment of applications that transmit and receive audio content over the
networks. The problem of providing a jitter free audio content over the network is an issue under
extensive research. The time since the generation of packet at the source and its reception at the
destination can fluctuate from one packet to another. This phenomenon is referred to as jitter.
The effective utilization of network bandwidth and the rate at which data is transmitted are the
important factors that decide the audio quality and minimization of jitters. These are achieved by
the loss recovery schemes that attempt to preserve acceptable audio quality even in the
presence of packet loss. Listening to music over Internet is aided by a system called Streaming
server. Streaming servers are highly influenced by the existing network parameters like server
load, congestion and the protocol in use. Our project unfolded an approach using Interleaved
Forward Error Correction technique for contiguous listening pleasure. With this approach, we
were able to find a significant increase in the listening throughput of high-quality audio transmitted
across the network.
COURSE PROJECTS

Designed and implemented multiprogramming, virtual memory management,
synchronization of threads & I/O simulation, in NACHOS, a simple, working OS.

Implemented a Compiler for Tiger. The project includes implementation of lexical
analysis, parsing, abstract syntax, semantic analysis, and translation to intermediate
code, register allocation and liveness analysis.

Implemented advanced data structures such as Red-Black Trees, skip lists and
various graph theoretic algorithms.

Chat Application over a Local Area Network using JAVA RMI concepts. This
application provides easy communication over a Local Area Network or
interconnected networks. Developed with Java's Remote Method Invocation
concepts, the server program resides on a remote computer and the user chat
interface resides on every client interface. A dedicated server is not required; any
local system could serve as the server.
