Developing Smart Gateway using Wipro Home Gateway software

 

 
The customer
A world leader in Networking Semiconductors based in the USA
 
The challenge
The networking semiconductor giant has developed Smart Gateway 857 IAD reference platform, a comprehensive hardware and software platform solution designed to streamline the development of residential and SOHO (small office/home office) gateway products such as DSL modems and routers, Ethernet routers, and integrated access devices (IADs). Smart Gateway is powered by Wipro’s ready to use DSL IAD software solution, a part of Wipro Home Gateway portfolio of software solutions. The challenges for Wipro in this project were:
The Wipro DSL IAD software solution should fit into a very constrained memory environment of 4MB FLASH and 16MB RAM of Smart Gateway
The Smart Gateway ported with Wipro’s software should be end user ready. Meaning that the DLS IAD Configuration User Interface presented should be end user friendly. In this case, the end users of the DSL IAD product are the house hold users
The Wipro DSL IAD software solution should be easily integratable with the Board Support Package drivers that were being developed by our customer
The Wipro DSL IAD software solution should be able to provide the best in class VPN features using the IPSEC Encryption support provided in the hardware of the DSL IAD platform
 
The solution

Wipro’s DSL IAD software solution was heavily pruned and performance optimized (with elimination of non necessary features) so that it could operate with in the memory constraints posed by the platform and still gives the high performance. Wipro DSL IAD software solution had been pre-bundled with an end user targeted HTML based User Interface for the IAD configuration and management. The HTML UI was field tested with a few end users of this solution and customized to the actual usage patterns. Wipro VPN software stack had well defined Interfaces and APIs for integrating with the crypto algorithms implemented in customer’s hardware, that simplified the task of using the encryption provided in hardware. The software team from Wipro was in sync with the BSP team of the customer and as and when the revisions happened in the driver codes, the Wipro DSL IAD application software were appropriately modified and retested.

 
Key benefits
With the help of the pre-built and ready to use DSL IAD software solution from Wipro, the customer was able to significantly reduce his development and time cost and was able to build a cost effective DSL IAD reference platform. The product reference platform was built very fast due to the usage of the IP components and services from Wipro, which has given substantial time to market advantage to our customer.
