                     draft-ietf-l3vpn-end-system-06

Abstract

   This document describes a solution in which the control plane
   protocol specified in BGP/MPLS IP VPNs is used and extended via the
   XMPP protocol to provide a Virtual Network service to end-systems
   (hosts).  These end-systems may be used to provide network services
   or may host end-user applications.

1.  Introduction

   This document describes the requirements for a network virtualization
   solution that provides an IP service to end-system virtual
   interfaces.  It then discusses how the control plane for BGP IP VPNs
   [RFC4364] can be used and extended via the XMPP protocol to provide a
   solution that meets these requirements.  Subsequent sections provide
   a detailed discussion of the control and forwarding plane components.

   In BGP IP VPNs, Customer Edge (CE) interfaces connect to a Provider
   Edge (PE) device which provides both the control plane and VPN
   encapsulation functions required to implement a Virtual Network
   service.  This document describes how the control plane and
   forwarding functionality of a PE device can be decoupled in order to
