Packet Transmission In A Network

Abstract

The project “Packet transmission in a network” is designed using Microsoft Visual Studio.Net 2005 as front end and Microsoft SQL Server 2000 as backend which works in .Net framework version 2.0. The coding language used is C# .Net.

A data packet transmission network comprises a stream of packets of data sent by a first terminal passes in transit through at least one network equipment to the destination terminal. The method comprises the following steps: the first terminal sends a specific stream of packets, each having a different determined size, the sizes being such that in a set of r packets, r being a positive integer less than or equal to the number of packets of the stream, there are not two subsets comprising the same number of packets and having the same cumulative total size.

The packets are transferred through an intermediate terminal to the destination terminal. After reaching the destination the packets are rearranged to get the original data. Thus packets are correctly transferred to the intended destination.

PROJECT DESCRIPTION

PACKET TRANSMISSION IN A NETWORK

The project titled “MULTIPLE SITE FILE TRANSFER PROTOCOL” is designed using Active Server Pages .NET with Microsoft Visual Studio.Net 2005 as front end and Microsoft SQL Server 2000 as back end which works in .Net framework version 2.0. The coding language used is C# .Net. The system “MULTIPLE SITE FILE TRANSFER PROTOCOL” is developed to work in the front-end as file transferring system. In this we can upload/download files. User can register then upload, download and list the files in FTP. File Transfer Protocol, or MSFTP, is a protocol used for transferring files from one computer to another – typically from your computer to a web server. FTP is the preferred method of exchanging files because it’s faster than other protocols like HTTP or POP. If you need to exchange large files, you should consider MSFTP. MSFTP data is sent and received through computer port 21 and under the TCP protocol. The transfer is asynchronous, meaning not at the same time and therefore faster than other protocols.

1.To promote sharing of files (computer programs and/or data),

2.To encourage indirect or implicit (via programs) use of remote computers,

3.To shield a user from variations in file storage systems among hosts, and

4.To transfer data reliably and efficiently.

The multiple site file transfer protocol contains four main modules. Those modules are

Register

This module is used to register the user details for upload or download in remote sites.

Upload

This module is used for upload the files which is already stored in the system to multiple sites using FTP in parallel manner. Settings:
Here we first set the FTP authentication for remote site to upload files.
Upload File:
Here we select the file and upload to multiple sites parallely.

Login

This module is used for authenticate user to enter into his area and upload or download files using FTP.

Download

This module is used for download the files from remote site and save it to the local machine. Settings:
Here we first set the FTP authentication for remote site to download files.
List:
Here we can list files in the remote site to select for download. Download File:
Here we select the file from list and download to local machine.

Conclusion

EXISTING SYSTEM

In the existing system, we can upload a file only to a single site. This means that the file uploaded by the user will be uploaded only to one site. The uploaded file can not be viewed directly from the site but it can be opened in local machine. The main drawbacks of the existing system are: Single site upload process
No Distributed File Transfer
Maintenance of single FTP session only
 No file segmentation process and
No Load Distribution process.

PROPOSED SYSTEM

The proposed system involves a web site that is useful to upload and download a file in remote sites using FTP.
Here we are going to upload a file to multiple sites simultaneously to save the time and roundtrip of file upload process and we can select any site and easily download a file from remote site. Multiple site upload process
Distributed File Transfer
Maintaining multiple FTP sessions
