In the winter of 2000-2001, Terra Soft was engaged by CoSine Communications, a provider of managed network-based IP Service Delivery
Platforms for service providers, to design and develop small footprint kernels for a proposed 3-tier PowerPC blade architecture. In the
course of an onsite three-day, rapid prototype session, the Terra Soft team built RAM disk images with fully functional ssh access for a
defined 1.4 MB footprint.
The IPSG Service Generator ran a Yellow Dog Linux BSP with modified kernel, as announced in a November 2001.
IPSG is a self-contained subsystem for the IPSX 3500 and IPSX 9500 processing switches that enables service providers to deliver computationally-intense network services such as firewalls, MPLS/IPSec VPNs, Frame Relay integration services, DSL aggregation and moreí at multi-gigabit wire speeds.
Using an innovative "switch on a blade" design, CoSine's service generators support a wide-range of interfaces, including multi-gigabit Ethernet and SONET rates up to OC-48. This unique architecture provides unprecedented processing capabilities designed to match the capacity of service providers' edge transport build outs, and allows them to bundle network-based, value-added services seamlessly with their high-speed access services.
Terra Soft was subsequently engaged to develop a suite of cross build tools as the applications are built on i686's running Red Hat Linux, and then moved to the PowerPC blades.
