Among the cool demos today at WinHec is the Scalable Networking Pack. Through the introduction of new architectural innovations like TCP Chimney Offload and NetDMA, the Scalable Networking initiative seeks to deliver support for the latest network acceleration and hardware-based offload technologies without requiring changes to existing applications or network management practices.

The Microsoft Windows Server 2003 Scalable Networking Pack is the first delivery of this initiative. It enables Windows Server 2003 administrators to cost-effectively scale their network-based applications while optimizing server performance and maximizing network throughput.
