Toolset For Network Data Availability is a private data file transferring that makes use of the public LAN Network infrastructure, maintaining privacy and security procedures. The idea of the Toolset For Network Data Availability is to give the company the same capabilities of file sharing using socket classes in java.
A well-designed Toolset using Socket, file features of java can provide great benefits for an organization. It can:

Extend geographic connectivity.
Improve data security and accessibility.
Reduce time consumption of traditional LAN.
Transmission of data using a TCP/IP in such a way that routing nodes in the LAN network are unaware that the transmission is part of a LAN network.Transmission is generally done by encapsulating the data in packets and specifying protocol information in port within the Socket class object.so that the packetised data is not available to anyone examining the transmitted data frames.It allows the use of LAN, To carry data on behalf of users as though they had access to a LAN, hence the name.

Implementation of Toolset For Network Data Availability
The proposed System will have three modules.

Explorer Login
Gateway
File Upload File Download
Explorer Login
The Explorer is a desktop application, which is used to browse, find and transfer files through the network. This application must be installed in all the machines in each network.Only authorized users are allowed to access the explorer program. It will Process once the values are entered successfully, then only the user will be allowed to access the main interface of the program.

File Upload File Download
The Explorer will list out all the files with icon, the client reads the file from the authorized server folder in the requested network. The file content will be read by the client host and will be saved in the client network folders. The user can upload and download files to and from the server.

Gateway
Gateway encapsulating the private network data and protocol information within the TCP/IP network protocol data so that the data is not available to anyone examining the transmitted data frames. specifying protocol information in port within the Socket class.so that the packetised data is not available to anyone examining the transmitted data frames.It allows the use of LAN, To carry data on behalf of users as though they had access to a LAN, hence the name
