Mailslots has Aspect Oriented architecture and is developed on largest Open Source project development website, http://www.sourceforge.net/. For detail see http://mailslots.sourceforge.net/mailslots.htm.

Projects:

· Designed and Implemented a multithreaded ftp server for Solaris that complies with RFC 959.This project is designed by using design patterns, UML and is implemented in C++.

· Implemented, Power ALU, an 8-bit Microprocessor in Verilog whose features are, division based upon Newton -Raphson Method, multiplication, addition/subtraction and basic logical operations.

· Implemented Symbolic Links and Multi-level Feedback Queues Scheduling Policy for Minix.

· Designed a complete University Database in 3rd Normal Form and implemented in MS-Access.

· Solved a set partitioning problem by using different IPC techniques on UNIX and suggested its design based upon Multi-Dimensional Separation Of Concerns (MDSOC).

Research Project : Mailslots
___________________________________________________________________________________________________________________________________________________________

Mailslots is a connectionless, message passing inter process communication technique implemented on Linux. Processes can communicate by exchanging discrete messages through a mailslot, which is created by a process called owner of the mailslot. The owner process decides the access permissions to the mailslot at the time of its creation or at any time later. Different message sizes are supported to improve efficiency. Mailslots has file descriptor based user interface. A mailslot is removed once all the open file descriptors to it are closed.

This IPC has Aspect-Oriented architecture and is implemented along the guidelines of an AOSD framework for system software development, which is given by our concurrent research group at Illinois Institute of Technology, www.iit.edu/~concur.

As Mailslots is a discrete message channel it is compared with System V and POSIX Message Queues and not with stream channels, e.g., Sockets and FIFO. Following is a brief introduction to the salient features supported by Mailslots. For more information please see http://mailslots.sourceforge.net/mailslots.htm.

Typed Messages: Like System V message queues Mailslots provides support of typed messages. It means a type number can be assigned to a message and a receiver can block for a particular message type. This feature is not available in POSIX Message Queues.

Asynchronous Notification: Multiple processes can register for a POSIX real-time signal or SIGIO, which will be delivered to the process every time a new message arrives in the mailslot. This feature is not supported by System V Message Queues.

File Descriptor Based Interface: Mailslots offers a file descriptor based interface, which facilitates the use of standard file I/O calls, e.g. read, write and close. This makes the user interface very simple. None of the Message Queues has this feature.

I/O Multiplexing: Mailslots, like I/O devices, pipes and sockets can be polled by kernel on behalf of a process. There are two standard system calls at the user level, select and poll, which are used for this purpose. This is another advantage of the file descriptor based interface since select and poll are file descriptor based system calls. Either System V or POSIX Message Queues does not support this facility.

Role Based Security: Mailslots employs a role based security model. In a system, a process plays the role of a user. For example when the "passwd" program is run, the "passwd" process plays the role of root so that the password can be changed. This idea of role can be further extended upon and a process can play the role of a child process, a process in the same process group, a process in the same session and many others. Depending upon the role a process is playing at any time, the access to a resource by that process can be determined.

Implementation: Mailslots has been implemented for Linux because of its modular architecture. It is divided in four loadable kernel modules that are linked with the running kernel.
