Abstract

The invention provides for the connection of a plurality of remote applications with a data source, to maximize the speed and reliability of data transfer. An interface module interfaces with a remote application such as a web browser. A port module interfaces between interface module and a data source. A connection manager facilitates the interface between the interface module and the port module. The port module detects the unavailability of the data source in response to an initial request for the data source by the remote application. The port module may then dynamically detect the availability of the data source in response to a subsequent request for the data source and re-connect to the data source to the remote application in response to the subsequent request without having to reinitialize the connection manager.

Claims

1. A computer implemented method comprising:

dynamically detecting, by a port associated with a data source, availability of the data source, the data source having a previously established connection with a remote application in response to a initial request for the data source by the remote application; and

reestablishing, by the port, a connection with the data source independent of re-initialization of other connections to the data source.

2. The method of claim 1, further comprising:

directly connecting an interface of the remote application and at least one port of the data source for communicating independently from the connection manager in subsequent communications.

3. The method of claim 1, further comprising:

after receiving the subsequent request from the interface, accessing a log file to determine a previous status of the data source.

4. A computer readable storage medium having stored thereon computer executable instructions for performing a method comprising:

dynamically detecting, by a port associated with a data source, availability of the data source, the data source having a previously established connection with a remote application response to an initial request for the data source by the remote application; and

reestablishing, by the port, a connection with the data source independent of re-initialization of other connections to the data source.

5. The method of claim 4, further comprising:

directly connecting an interface of the remote application and at least one port of the data source for communicating independently from the connection manager in subsequent communications.

6. The method of claim 4, further comprising:

after receiving the subsequent request from the interface, accessing a log file to determine a previous status of the data source.

7. A system for connecting a plurality of remote applications with a data source, the system comprising:

at least ne port associated with a data source, configured to dynamically detect availability of the data source, the data source having a previously established connection with a remote application in response to an initial request for the data source by the remote application; and

reestablishing a connection with the data source independent of re-initialization of other connections to the data source.

8. The system of claim 7, wherein an interface of the remote application and the at least one port of the data source are directly connected for communicating independently from the connection manager in subsequent communications.

9. The system of claim 8, wherein after receiving the subsequent request from the interface, a log file is accessed to determine a previous status of the data source.
