-Reference Architecture
-----------------------
-
-This section describes the reference architecture, the function blocks,
-and the function entities of Escalator for the reader to well understand how
-the basic functions to be organized.
-
-1. Upgrade Scope
-~~~~~~~~~~~~~~~~
-Upgrade objects described in this document are software programs covered by
-red box in the picture below which includes: VIM and NFVI.
-The target of the upgrade is to reduce the impact on the applications in the
-blue box below as much as possible.
-Note that this upgrade process does not take into consideration the effects
-of Vi-Vnfm and Or-Vi. In other words, the unserviceability of the two
-interfaces during upgrade can  be accepted.

-The software stack on each node is generally as shown in the table below.

-
-Because the control node upgrade will not affect the business in the blue box,
-this scheme focuses on upgrading of compute nodes.
-
-2. Precondition of Upgrade
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-2.1 The environmental requirements
-1.  System is running normally. If there are any faults before the upgrade, it
-is difficult to distinguish between upgrade introduced and the environment
-itself.
-2.  The environment should have the redundant resources. Because the upgrade
-process is based on the business migration, in the absence of resource
-redundancy,it is impossible to realize the business migration, as well as to
-achieve a smooth upgrade.
-
-Resource redundancy in two levels:
-1)  NFVI level: This level is mainly the compute nodes resource redundancy.
-During the upgrade, the virtual machine on business can be migrated to another
-free compute node.
-2)  VNF level: This level depends on backup mechanism in VNF, such as:
-active-standby, load balance. In this case, as long as business of the target
-node on VMs is migrated to other free nodes, the migration of VM might not be
-necessary.
-
-The way of redundancy to be used is subject to the specific environment.
-Generally speaking, the impact of using NFVI redundancy on the VMs is larger
-than the rearrangement of the business on VNF level.
-
-2.2 The demand for version
-This is primarily a compatibility requirement. You can refer to Linux/Python
-Compatible Semantic Versioning 3.0.0:
-
-Given a version number MAJOR.MINOR.PATCH, increment the:
-1.  MAJOR version when you make incompatible API changes,
-2.  MINOR version when you add functionality in a backwards-compatible manner,
-3.  PATCH version when you make backwards-compatible bug fixes.
-
-The upgrade process needs to use some interfaces which require these
-interfaces to be backward compatible. Refer to "Interface" chapter for details.
-
-3.Upgrade related modules in VIM
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Upgrade operations are initiated by the user through the VIM. For VIM, upgrade
-management mainly contains the object:
-**Upgrade Manager**:Mainly responsible for upgrading process control. Physical
-nodes information of each node is saved in upgrade manager.
-**VIM Interface**:Mainly responsible for the external interface, include
-Vi-Vnfm, Or-Vi. This module stores VNFO and VNFM external information such as
-address and authentication.
-**Cloud Manager**:Mainly responsible for virtualization resources management,
-which might be considered made up of Openstack and SDN control node.
-**System Support**:Provide the upper software running environment, including:
-OS, HA, etc. To upgrade the upper software is based on this module.
