           draft-gu-sdnrg-network-management-consideration-02

Abstract

   This draft introduces consideration about SDN network management
   after the deployment of SDN and NFV in cloud datacenters.  The
   content of SDN network management and some specific technique are
   included from the network administrator's point of view.

1.  Introduction

   In cloud datacenter, virtualized infrastructure of virtual machines
   and physcial infrastructure of bare-metal servers are both deployed
   in the network.  Actually Openstack K version, SDN controller, open
   virtual switch, SDN ToR (top of rack) switches and SDN gateways act
   as network devices.  In this cloud-based deployment, Openstack
   manages computing, storage and network of the entire system by its
   modules including neutron, nova, ironic, swift and so on.  SDN
   controller is responsible for the network provision and management.
   It receives messages of network operations from applications or
   Openstack neutron and translates them into commands/operations for
   forwarding devices such as open virtual switch, SDN ToR and SDN
   gateways.

   Network administrators face the task of SDN network management after
   the practical deployment of these heterogeneous devices and networks
   in several levels.  Up to now, our network administrator focuses SDN
   management on network topology, network detection and monitoring.

   During research we found out difficulties and confusions in several
   aspects:
