Case Studies> > Windows PPPoE IM Driver

The Customer
Our customer is a technology company providing equipments for Wireless Local Loop.

The Challenge
The customer wished to develop a dialer using Ethernet adapters by using the PPPoE technology on Windows 98. i.e. The driver software should be able to emulate PPP over the Ethernet connection. Also, it needed application and configuration software to create and configure the dialer.

The Solution

The requirement needed the implementation of a Windows NDIS Intermediate driver to implement the PPPoE RFC. The intermediate driver would have a protocol interface at the lower edge for communicating with the NDIS miniport drivers. It would have a WAN Miniport interface at the upper edge to communicate with NDISWAN intermediate driver provided by Windows. In addition, it allows TCP MSS clamping and configuration of TCP MSS and MTU.

The software was developed in 3 months time.

The Technology

The complexity of the project was in understanding the intricacies of Intermediate driver on Windows 98 as the documentation is not clear/non existent.

The Result

The customer was very happy with the quality, fast delivery time and the low development cost. More so as their earlier effort in getting it done from some other company had failed. Also, This project enabled GRACELABS to build on its technical resources in the areas of Intermediate drivers on Windows and PPPoE.

Also, the customer entrusted GRACELABS with providing the same software on other Operating systems.
