Products # Vision Intranet System Vistion is a template based intranet system productized for the world markets. This has evolved out of generic corporate need worldwide for fairly consistent intranet systems that need to be implemented fast and where maintenance should be low resource hungry and quick. The product is being built with a wide spectrum of features such as video conferencing, IP-telephony, and voice over mail/facsimile, chat rooms, email, company related information (profile, projects, manpower skill set, methodology adopted for project handling including in-depth analysis of system requirement specifications, data flow diagram, design document, testing methods, documentation.). The concept is brought out in such a form that any company has to only transplant its corresponding information and ideologies and than attach the same as its extranet. # VOIP (Voice Over Internet Protocol) It is a fact that an employee spends about 32% of his job time in job communication where as he spends just 13% of his time for doing actual work. Here the VOICE OVER INTERNET PROTOCOL comes in to play a significant role for the benefit of the employee's and the management of a company Problem Analysis: In an organization the user of a computer with multimedia communicating with the other users having multimedia facility in the same organization and also with other users outside the organization with this 'VOICE OVER INTERNET PROTOCOL'. The conversion of format for audio and video in accordance with the card has to be developed for the system. The scenario of transmission of data is it audio or video will be looked upon in this project. The caller's identity has to be cautiously monitored for a perfect communication. The use of Java media player API is to be used to develop Java programs that presents time based media. All in all we need to provide a unified architecture and messaging protocol for managing the time-based media. Functional Analysis: For the functioning of VOICE OVER INTERNET PROTOCOL we thought to use JAVA MEDIA FRAMEWORK. The JAVA MEDIA FRAMEWORK includes JMF-STUDIO. In addition to this we extensively use java.net along with Java development Kit 1.2. The capturing of media is it audio and video is essentially the crux of the implementation. The designing of very scintillating GUI, which provide easy and enhanced user, interfaces which also provide quality and reliable communication through the user interfaces. We use RTP (real time transport protocol) and UDP (user data gram protocol) for the communication between multimedia systems. UDP is faster than TCP/IP, which is why we preferred UDP to TCP/IP for this VOICE OVER INTERNET PROTOCOL. RTP enables the transmission and reception of real-time media streams across the network. RTP can be used for media on demand applications as well as interactive services such as Internet telephony once the connection is established the sender has to wait for a maximum of one minute and then send voice mail. G.723 is typically used to produce low bit rate speech for telephony applications. Saving the received messages for further Correspondence should be done in accordance with the audio and video Format. Special care has to be taken to save a message in a suitable format.
This package has been developed based on the guidelines provided by Watts Humphrey at SEI (Software Engineering Institute) CMU, with the objective of applying CMM (Capability Maturity Model) framework to small projects. It is useful to deliver the high quality software with in the given time and budget constrains, consistently and efficiently. It can be applied at all phases of software life cycle development and is best suited for small organizations and individual practices. The main essence of the project involves in keeping track of the time taken and defects encountered during the various stages of the project such as Planning, Design, Coding, Code review, Compiling, Testing and Post-mortem. During the initial stages of a project the estimated times are entered which are later on compared with the actual values. Standard formulas have been used to calculate the Defects injected/KDSI (Kilo Delivered Source Instructions), Yield and Appraisal/Failure Ratio. It helps in: 1.
Estimation of project duration and phase-wise
duration
This package has been developed based on the guidelines provided by Sun Java Mail API (Application Program Interface). Basically the overall scenario of this package is to fill all the needs of the mail system. It's a generalized product to any web-based application i.e., portals. Most of the mailing system was developed in CGI/Perl but those mails does not support IMAP based mail-accounts. But our mail system will support IMAP as well as POP3 (Post Office Protocol) and SMTP (Simple Mail Transfer Protocol). Our Mail System consists of three distinct components: a "User Agent" that lets users read and compose mail, a "Transport Agent" that forwards messages among machines, and a "Delivery agent" that places messages in the receiving users mailboxes. Exhibit a shows the relationship of these components.
This is a sample product, Transportation Logistic Management System,for an organisation having their Transportation department in the following operational areas; 1.
Allotment Overall Technology related to the solution is a Client/Server Technology using SQL Server (Back End) and Visual Basic As the client (Front End).
