This document provides an overview of Virtual Network Switching (VNS).
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.
VNS has been proven in production networks for several years.
