<t>
This document provides an overview of Virtual Network Switching
   (VNS).
</t>
<t>
   VNS is a multi-protocol switching architecture that provides COS-
   sensitive packet switching, reduces the complexity of operating
   protocols like PPP and frame relay, provides logical networks and
   traffic segregation for Virtual Private Networks (VPNs), security and
   traffic engineering, enables efficient WAN broadcasting and
   multicasting, and reduces address space requirements. VNS reduces the
   number of routing hops over the WAN by switching packets based on
   labels.
</t>
<t>
   VNS has been proven in production networks for several years.
