                   Network Monitoring Protocol (NMP)
                 draft-gu-network-mornitoring-protol-00

Abstract

   To enable automated network OAM (Operations, administration and
   management), the availability of network protocol running status
   information is a fundamental step.  In this document, a network
   monitoring protocol (NMP) is proposed to provision the information
   related to running status of IGP (Interior Gateway Protocol) and
   other control protocols.  It can facilitate the network
   troubleshooting of control protocols in a network domain.  Typical
   network issues are illustrated as the usecases of NMP for ISIS to
   showcase the necessity of NMP.  Then the operations and the message
   formats of NMP for ISIS are defined.  In this document ISIS is used
   as the illustration protocol, and the case of OSPF and other control
   protocols will be included in the future version.

1.  Introduction

1.1.  Motivation

   The requirement for better network OAM approaches has been greatly
   driven by the network evolvement.  Network OAM provides visibility to
   the network health conditions, and is beneficial for faster network
