Affirmed Networks Inc. is an entrepreneurial Massachusetts company with a product line based on carrier-class, non-stop data network equipment and software for mobile subscriber gateway data and voice services. 

The Affirmed Networks product family includes an original line of purpose-built communication servers and an extensible cluster based on embedded Linux virtual machines. 

The work that I was brought in for initially was cluster configuration management for the ATCA products acting as a combined subscriber and data services gateway for mobile subscribers.  A follow-on project involved substantial Linux kernel and user-space support for Multi-Protocol Label-Switch routing for the Linux-VM clusters.  Data-plane and control-plane C++ support provided dynamic route updates based on standard router protocols (BGP).
