Master's Thesis: A study of

Relativistic Electrons in Solids. List of a few very Critical Assignments 1. Name: Web based network Management system

Customer: Wellknit Communications Inc. San Jos area., CA

Duration: Jan 97 to June 97.

Keywords: HTTP server, NMS, POSIX threads, Java

Role: Project Manager.

This project is a Web/applet based implementation of an NMS.

The applet that would manage the network device would reside on the device

itself. This would be access via the browser for network admin.

Thus the project had three sub projects. They are:

design & implementation of a web browser that can be

portable to an embedded OS/RTOS; design of the applets for the devices (done by the

customer);Implementation of the Java based MIB database with API

and viewer. This would be used by the applet to save the

data on the local disk provided the browser security

could be configured.

I lead two teams - one for (a) and the other for (b).

The Web-server was implemented first on Linux kernel 2.0 using

Provenzano's (MIT) pthreads. These threads schedule in the user

space and therefore can be easily ported to any embedded OS. Two

solutions was provided to the inter-thread communication, one via

message queues and the other via mutex's supported by the thread

library. This was for the ease of porting.

The Java based database was developed using Symantec's Visual

Caf . It was a simple database using Java's hashing function for

index based search. It supported simple API's and had a database

viewer. The raison-d' tre of this module is that in certain

(then future) browsers the applet security can be configured for

the applet to access the local hard disk. In that case the

downloaded MIB's can be saved on the local hard-disk.

2. Name: Information restructuring of PSI Data System

Customer: PSI - Data.,

Duration: June 95 to July 96.

Keywords: System Integration; Networking design & implementation

Role: Assignment owner.

In the coming Information Age it was decided to "tightly couple"

the organization to the Internet. This needed the following to be

set up: A proper integration of PSI's internal buildings to form

an integrated IP network Design & implementation of WAN links to connect the 2 sites Proper design of LAN's to prevent traffic blocks Connectivity of the gateway Router to the Internet Setting up the Intranet to easy document interchange Setting up WWW, SMTP, POP3 and FTP servers inside

the enterprise

This required a holistic view of the Network. LAN design was made

with switches as the backbone. Radio bridge was used to connect the

buildings to the central router. The Internet connection was via

a 64Kbps Radio-bridge to ISP. A WWW server was implemented using

Apache server on Linux 1.3.93. MIME standards were used to exchange

documents.

3. Name: Material Management Systems.

Customer: PSI - Data. Materials & Finance dept

Duration: 7 Months. (Jan 94 to Nov. - 94)

Keywords: BC++ v4.0, SYBASE, OOPs, Client-Server, MRP-I

Role: Project Manager

This is an application to automate the management of the Indent life-cycle together with the associated PO process. The product is a Windows based client application where SYBASE is a back-end SQL server. The product is OO based using Borland's C++ ver 4.0 along with its OWL.

SYBASE client db-library was used as the supporting session protocol.

Data-base classes were designed and data-base operations and views were abstracted into template based classes. The UI was class structure was automated using BC++ tools. Advanced C++ features like exception handling, templates and Run-Time Type identification were also employed. 4. Name: Re-engineering

Ampview 1.0; NMS for AMP's Token-ring concentrator.

Customer: AMP Inc., (Harrisburg, USA)

Duration: 7 Months. (Nov. 92 to May 93) [On-Site]

Keywords:

UNIX (SUNsparc v 4.3), SNMP, TCP/IP, Token-ring, Motif, C-ISAM,

PPP on streams, BOOTP

Role: Project Leader (Client was PM)

(Dream Assignment # 2 )

This was initially a re-engineering project where the job was first given to an US Software house that failed to deliver the goods. I led a team from Bangalore to take-over the operations. The initial project was rejuvenated by our team and extra functionalities added.

This is the reason that I consider it my second dream assignment. It entailed cautious interaction, working with people from whom we are taking the assignment away and working with conflicting interests keeping the job-completion in mind.

This is a Network Management System for a Token Ring network based on AMP Token Ring concentrator using SNMP. The hub supported an extension of MIB-II on a 80186 based agent.

The functionalities of the package included, topology derivation, event logging and alarm notification on higher event density etc. Also the team left with the design of ghost topologies (Not now in network but earlier was).

The product was for SUNsparc using Motif as the GUI, C-ISAM was the Database support and PPP on a "streams" driver was used for "out-of- band" communication with the hubs.

5. Name: PSOM (A PC based Telecom network mgmt. system)

Customer: ADC Telecom (Minneapolis, USA)

Duration: 10 Months. (March 91 to Jan 92) [Off-Shore]

Keywords:

PC / DOS, Vermont Views, Serial Port Communication,

(DOS Device drivers), C-ISAM for DOS., C & in-line assembly,

Thread impl. in DOS

Role: Project leader & customer interaction

( Dream Assignment # 1 )

This was a PC based Network Management product for ADC Telecom.

The product was running on DOS. The front-end was a GUI interface using Vermont Views and the back-end was the network manager polling the comm. ports and taking timer based actions.

C-ISAM for DOS was used as the Database. The DOS program trapped the timer intr. to provide a background daemon for communication protocol management. The Serial port communication management was designed & implemented by us.

I consider this as my dream assignment for two reasons.

First: This project entailed network connection and monitoring in a non multitasking OS. This required using the timer-tick interrupt to implement threads.

Second: This was the first Off-Shore project for PSI where the entire communication was via e-mail. Thus, owing to the 12 hrs time difference, our days work was reviewed by the customer and we thus ran a virtual 24-hr development shop.
