5620 SAM role in NFV solution 2-3

Network function virtualization overview

General information

Network function virtualization (NFV) allows network administrators to uncouple

network functions from underlay hardware network elements so that they can run as

software images. These network functions include load balancers, firewalls, and NAT.

The purpose of NFV is to provide a simpler way to deliver and manage the network

components required for a virtualized infrastructure. Network administrators are able to

dynamically deploy network elements and services without needing to physically

provision the underlying routers. The virtualized network element which represents the

physical node is called a virtualized network function (VNF).

OpenStack

OpenStack is an open-source cloud management system (CMS) that can be used for NFV

management. OpenStack provides the NFV infrastructure and orchestration components

that can be used to perform lifecycle management tasks on managed VNFs and other

virtualized network elements.

...................................................................................................................................................................................................................................

5620 SAM



2-1

The 5620 SAM provides an interface with OpenStack through the VNF Manager

application.

Orchestration

OpenStack orchestration allows the user to manage the lifecycle of VNFs and network

infrastructure within the OpenStack cloud. The module used for orchestration is called

Heat. The Heat orchestration engine is designed to launch cloud applications based on

template files which are specialized for different types of VNFs. These Heat orchestration

template (HOT) files describe a list of OpenStack resources called a stack. Heat maps

these resources to VMs based on VNF requirements.

HOT files can be used to define the following VNF specifications:

• resource allocation

• lifecycle tasks, including deployment, rebooting, and scaling

• auto-scaling instructions

Cloud Management

In addition to Heat, OpenStack uses several other modules for VNF management.

OpenStack cloud management programs include the following

• Nova—compute component used to compute resources

• Glance—discovery and provisioning for disk and server images

• Neutron—OpenStack networking

• Cinder—block-level storage

• Ceilometer—billing and telemetry

• Keystone—authentication

2-2 5620 SAM



5620 SAM role in NFV solution

General information

The 5620 SAM provides an interface with OpenStack to enhance VNF management with

more monitoring, assurance, and management functionality. This NFV-aware NMS

extends 5620 SAM existing network element management and assurance to VNFs and

VNF lifecycle functions. The 5620 SAM NFV feature set is composed of two

applications (VNF Monitoring and VNF Manager) as well as support for VNF EMS in

the 5620 SAM Java GUI.

VNF assurance and monitoring

The 5620 SAM improves visibility of faults in the VNF network with alarm management.

You can use the VNF Monitoring application to view all alarms in a VNF supervision

group, and have the ability to drill down to a specific VNF or VNFC. The 5620 SAM

reduces alarm volume and quickens fault resolution by correlating alarms between the

VNF application and the virtual infrastructure. You can also view alarms for VNFs in the

5620 SAM Java GUI, which gives you access to more alarm management functionality,

such as TCAs.

5620 SAM



2-3

The VNF Monitoring application provides a simplified dashboard view of VNFs in the

network. It allows you to track KPIs such as down VNFCs to determine the overall health

trend of your network. You can quickly assess network performance, outages, and VNF

availability using the Watch List or Group Matrix. You can use this information to

determine if a capacity change (scale-in or scale-out) is required.

You can configure the 5620 SAM to perform an automatic scale-out and automatic

healing based on capacity thresholds or network reachability events. Automatic scale-out

is supported for the VMG and the VMM. Automatic healing is supported for the VMM.

See Chapter 3, “VNF web applications” for more information on the VNF Monitoring

application.

VNF management

The 5620 SAM provides an interface with OpenStack Heat to allow you to perform VNF

lifecycle tasks from the VNF Manager application. You can perform the following

lifecycle tasks directly from within the VNF Manager application:

• Instantiation—create a new VNF instance from a specified cloud access point and

assign it to a VNF catalog

• Deletion—destroy a VNF instance

• Deployment—deploy a VNF instance to the cloud network

• Scaling—reduce or expand processing capacity by adding VMs to a VNF

• Healing—reboot a failing VNF component

• Sync—synchronize a VNF with the OpenStack tenant

Note: Scale-in is not currently supported on the VMG.

See Chapter 3, “VNF web applications” for more information on the VNF Manager

application.

Supported VNFs

The 5620 SAM extends basic EMS support to virtual network elements. Discovery,

provisioning, and management workflows are the same as for physical nodes.

The 5620 SAM supports the following VNFs:

• VMG

• VMM

See the 5620 SAM User Guide for more information on NE discovery and management.

VMG

The Virtual Mobile Gateway (VMG) is a software-only version of the 7750 SR MG. It

supports the following virtualized applications:

• Packet Data Network Gateway (VMG-PGW)

• Gateway GPRS Support Node (VMG-GGSN)

• Serving Gateway (VMG-SGW)

• Evolved Packet Data Gateway (VMG-ePDG)

These virtualized applications can be deployed as separate network functions or in

combination (for example, VMG-SGW/ PGW/GGSN or VMG-SGW/ePDG).

The VMG supports multiple mobile gateway functions including PGW, GGSN, SGW,

and the combined SGW/PGW/GGSN. It also supports LTE profiles and policies, golden

configuration, LTE reference points, EPS peers and paths, and statistics. These functions

operate the same as they do on a physical 7750 MG.

The VMG consists of VMs operating as VNFCs. Each VM is dedicated to a specific set

of functions that are replicated across other VMs. A group of VMs are represented as a

single instance of an application. The VMs in the group operate in synchronization to

support a network functionality that can scale horizontally as required.

The VMG is composed of the following VNFCs:

• operations, administration, and management VM (OAM-VM)—performs control

plane functions including routing protocols, management interface functions such as

CLI configuration, and VNF/VNFC management

• load balancer VM (LB-VM)—provides network connectivity to mobile gateway

functions, load distribution across the MG-VMs, and forwarding of GTP-C/GTP-U

and UE-addressed packets to the MG-VM

• mobile gateway VM (MG-VM)—manages services including 3GPP call processing

(control and data plane), PCEF, and application assurance (PCEF-enhanced with ADC

for application detection and control, and L7 service classification for policy charging

control

You can configure automatic scale-out on the VMG. See Chapter 4, “NFV use cases” for

more information on automatic scale-out.

VMM

The Virtual Mobility Manager (VMM) is a software-only version of the 9471 WMM.

The VMM includes VNFCs for the following functions:

• OAM—performs control plane functions including routing protocols, management

interface functions such as CLI configuration, and VNF/VNFC management

• MIF and MAF—terminates and manages interface links within the VMM

• MPH—terminates the SCTP, UDP, and TCP layers

....................................................................................................................................................................................................................................

5620 SAM



2-5

You can enable automatic scale-out on the VMM and configure an automatic scale-out

threshold. The automatic scale-out threshold defines the point at which an automatic

scale-out operation can be triggered, where the threshold is the total UE capacity of the

VMM multiplied by the scale-out factor. When the threshold is reached and one or more

MAFs is affected by a resource overload node alarm, the 5620 SAM automatically

increases the processing capacity of the VMM by creating an additional virtual MAF on

the NE.

The Auto Scale-out Timer parameter prevents the 5620 SAM from triggering additional

scale-out operations while a previous scale-out is still in progress. You should specify a

length of time that exceeds the expected time for a virtual MAF to become operational.

You can also enable automatic healing on the VMM. If automatic healing is enabled, the

5620 SAM will attempt to reboot a VNFC when it goes down. The 5620 SAM attempts a

soft reboot first before attempting a hard reboot, if necessary.

See Chapter 4, “NFV use cases” for more information on automatic scale-out and healing.

VNF application cross-launch

The 5620 SAM supports cross-launching the VNF Manager and VNF Monitoring

applications from the VNF or VNFC in the equipment tree. Cross-launching to the VNF

Manager application allows you to perform manual lifecycle management tasks such as

VNF instantiation or scaling. Cross-launching the VNF Monitoring application allows

you to view the selected VNF or VNFC in the context of its supervision group. To

cross-launch a VNF application from the equipment tree, right-click a network element or

card slot and choose VNF Management to select an application to launch.

Note: Context-specific cross-launch is planned for a future release of the 5620 SAM.

Licensing

The 5620 SAM allows you to view 5620 SAM NFV license statuses and counters in the

Java GUI. The license status is listed as either valid, invalid, no license, or locked. You

can view license counters to see how many 5620 SAM VNF and VNFC licenses of each

type have been consumed. The 5620 SAM raises a node license alarm when the license is

invalid and includes a UUID.

Note: After the 5620 SAM discovers the number of VMG VNFs allowed by the

license, the 5620 SAM can no longer discover the VMG.

Element management

The 5620 SAM provides standard FCAPS support for the VMG and VMM, and other

managed network elements. Equipment management functionality such as alarms and

inventory is extended to include virtual network components.


....................................................................................................................................................................................................................................

Browser compatibility

The 5620 SAM applications are supported on the latest version of Mozilla Firefox and

Google Chrome. Each application user must ensure that the browser path is configured in

the user preferences. See the 5620 SAM User Guide for more information.

Access permissions

Access to the applications is controlled through 5620 SAM user groups. The default

admin user group can access all 5620 SAM applications. See the 5620 SAM System

Administrator Guide for more information about how to grant access permissions for

applications to a user group.

Product help tours

You can click on the Help button (?) in the application toolbar or on some panel toolbars

to view a list of help tours. These tours are designed to explain the application features

and provide workflows for completing management and monitoring tasks.

VNF Manager web application

General information

The VNF Manager application allows you to instantiate, maintain, and terminate VNFs

managed by the 5620 SAM. The 5620 SAM provides an interface with the cloud

management entity that provisions cloud resources. The 5620 SAM validates these

resources and provides assurance and monitoring through the VNF Manager application

and other features in the NFV solution.

Application interface

The VNF Manager application interface is divided into three panels for managing

catalogs, cloud access points, and VNFs.

VNF catalogs

You can use the VNF Manager application to create and manage VNF catalogs. A VNF

catalog is a collection of VNFs with a template that determines the type of VNF managed.

The catalog includes deployment specifications, KPIs, and recipes for VNF management

functions that are applicable to the VNF type. These become the default VNF settings that

are defined when you instantiate a VNF using the catalog. You are able to configure these

settings for specific VNFs during VNF instantiation.

You can create the following types of VNF catalogs:

• Generic

• VMG

• VMM

• VSR

5620 SAM



3-3

In addition to specifying the catalog type, you must also define a directory name. The

directory name is the VNF catalog directory where the HOT files are located. You should

also specify a version for the catalog item. You must configure a VNF catalog before you

create a VNF object.

Cloud access point

The VNF Manager application provides an interface with OpenStack for VNF

management. You must define a cloud access point before you create a VNF object. You

can use multiple cloud access points for VNFs under different tenants For each cloud

access point, you must provide login credentials for the tenant group and specify an

access point URL.

The cloud access point defines parameters such as VNFC image/flavor and

network/subnet ID which are configurable during VNF instantiation.

VNF management

The VNF Manager application provides an at-a-glance view of VNFs and VNFCs in the

network. VNF onboarding allows the application to archive, upload, and validate VNF

software images with OpenStack Heat.

The following table describes the lifecycle management tasks which can be executed

from the VNF Manager application.

Table 3-1 VNF life cycle management tasks

Button Description

Add Instantiates a new VNF. You must choose a catalog and cloud

access point when you create a new VNF.

Delete Terminates a VNF.

Deploy Deploys the VNF to OpenStack Heat. Newly instantiated VNFs

are not automatically deployed. The Deployment State

parameter shows whether the VNF has been deployed.

Scale-out Increases processing capacity by adding a VM. You must

specify the scaling template from the drop-down menu. The

scale out template defines the type and number of VNFCs to be

added.

Scale-in Decreases processing capacity by removing a VM. You must

specify the scaling template from the drop-down menu. The

scale in template defines the type and number of VNFCs to be

removed.

Sync Synchronizes the VNF with OpenStack Heat.

Reboot Reboots the VNF component. The Reboot button is available

from the VNF component list that opens when you select an

VNF.

Manual scaling

You can use the VNF Manager application to perform manual scale in or scale out to

adjust the processing capacity of a VNF. When you use a scaling operation, you must

select a scaling template to use. Each scaling template specifies a type and number of

VNFCs to be scaled in or out. The scale in and scale out operations use the same scaling

templates.

These scaling templates are defined by the VNF_Type.userdef_chars.grow.hot.yaml files

in the grow sub-directory of the VNF catalog directory. The name of the scaling templates

must specify the applicable VNF. A VMG scaling template must lead with vMG in the

template name and a VMM scaling template must lead with vMM. For example, a scaling

template designed to scale one load balancing VNF on a VMG might be named

vMG.1LB.grow.hot.yaml. It is recommended that the template name specifies the number

and type of VNFCs to be scaled.

For automatic scaling, the 5620 SAM looks for a file with the name VNF_Type.default-

.grow.hot.yaml.

Note: The userdef_chars part of the template filename cannot contain a period.

VNF instantiation

You can use the VNF Manager application to instantiate VNFs from a specified cloud

access point and assign them to a VNF catalog. The VNF catalog selected during VNF

instantiation defines the default settings that are required by the VNFD for lifecycle

management operations. These settings are read from the catalog .env.yaml file. You can

customize these settings for a specific VNF during instantiation, as required.

The OpenStack cloud access point defines the network and subnet ID for the VNF. It also

provides the list of available VNFC images and flavors. You can select the required

images and flavors from drop-down menus during VNF instantiation.

You can also configure the Site Name and System Address during VNF instantiation.

These parameters uniquely identify the VNF. Alarms affecting the VNF or associated

VNFCs list these parameters as Site Name and Site ID.

Note: The instantiated VNF is not deployed until you click Deploy.

VNFD redundancy

The 5620 SAM supports redundancy for the HOT files that define the lifecycle

management tasks performed by the VNF Manager application. These files are kept in the

/home/samnfv/os directory and required 5620 SAM administrator read/write privileges.

Whenever an rsync operation is triggered, files in the directory with a yaml extension are

duplicated into a standby file server. An rsync is triggered once every five minutes by

default, or as defined by the user in the nms-server.xml file. Changes in the

/home/samnfv/os directory on the active server are picked up every 30 minutes by default.

VNF Monitoring web application

General information

The VNF Monitoring application provides a dashboard for assessing the overall health of

your network. You can use the VNF Monitoring application to monitor groups of VNFs,

which are automatically updated as VNFs are added or removed. Each group can be

assessed based on KPIs and affecting alarms. You can also use the application to assign

VNF objects to a special watch list and to perform alarm management tasks.

Application interface

The VNF Monitoring application interface includes a watch view, summary view, and

group matrix. You can use the group matrix to drill down to VNF and VNFC lists and

associated alarm lists.

3-6 5620 SAM



The following figure shows the VNF Monitoring application with the VNFC List and

associated Alarm List displayed.

Summary views and supervision groups

A supervision group is a group of monitored VNFs. You can use a supervision group to

assess the overall health of a specified set of VNFs. You can click on a supervision group

to view a list of all VNFs in the group as well as all associated alarms. Supervision groups

are displayed in the summary view list and in the group matrix. They are colored green

(0%), yellow (1-40%), orange (41-60%), or red (>60%) based on the number of VNFs

that are down or partially down.

The VNF Monitoring application lists the following KPIs for a supervision group:

• VNFs down

• Total VNFs

• Trend

• VNFs with VNFC(s) down

• VNF(s) not Deployed

A summary view is a list of supervision groups to be displayed on the application

dashboard. You can switch between summary views using the drop-down menu on the

application toolbar.

You should configure supervision groups and summary views in the 5620 SAM Java GUI

before you use the VNF Monitoring application. See Chapter 4, “NFV use cases” for

more information on configuring summary views and supervision groups.

Watch view

You can use the watch view to assign VNFs for KPI monitoring. The watch view is useful

if you need to narrow your monitoring activities to a specific VNF, rather than an entire

supervision group. You can add VNFs to the watch view by clicking and dragging them

from the VNF list. You can hover over a VNF in the watch view to view the health trend.

Drill down

You can click on VNF supervision groups in the summary view or group matrix to drill

down to a list of VNFs. This list provides additional details about deployment status and

operational health. From the VNF list, you can drill down further to a list of VNFCs. Each

time you drill down, the alarm list updates with a list of alarms affecting the selected VNF

supervision group or VNF.

Alarm list

The alarm list provides a dashboard to view and manage alarms that are affecting the

selected VNF supervision group or VNF. You can use the alarm list to sort, search, and

filter alarms. You can also view alarm descriptions and remedial actions.

You can perform the following fault management and monitoring tasks for alarms

affecting VNFs in the VNF Monitoring application:

• view root cause and impacts

• view graphical representation of object impacts and object point of view

Supervision group configuration

Overview

The VNF Monitoring application monitors VNF supervision groups based on

user-defined summary views. You must configure supervision groups and summary views

in the 5620 SAM Java GUI before you can use the VNF Monitoring application. For each

supervision group, you can configure VNF inclusion filters to automatically update the

group based on specified criteria. You can also filter monitored alarms by severity.

The 5620 SAM automatically configures a default VNF supervision group and a default

summary view.

Automatic scale-out and healing

Overview

You can configure the 5620 SAM to perform automatic scale-out and healing operations

based on user and system-defined thresholds and network events.

A scale-out operation increases the call processing capacity of a VNF based on

system-defined or user-defined processing thresholds. Processing capacity is increased by

automatically creating and provisioning a VNFC. A healing operation reboots a VNFC.

Automatic healing is triggered by the 5620 SAM when an alarm reports against a VNFC.

The 5620 SAM performs addition tasks based on the results of the attempted healing

operation. You can enable automatic scale-out for the VMM and VMG, and automatic

healing for the VMM. This task must be performed by a system administrator.

VMM automatic scale-out

On the VMM, you can configure a processing threshold KPI which will raise an allocated

resource overload alarm when the threshold is reached. This alarm triggers an automatic

scale-out. When the threshold is reached, the 5620 SAM automatically increases the

processing capacity of the VMM by creating an additional virtual MAF on the NE.

You can also configure a scale-out timer which limits the frequency at which an automatic

scale-out can be triggered by the 5620 SAM.

VMG automatic scale-out

Automatic scale-out on the VMG is triggered by a user-defined threshold group counter.

You can specify a low/high threshold bearer limit. When the bearer management

threshold limit is reached, an RMON trap is raised. This alarm triggers an automatic

scale-out. When the threshold is reached, the 5620 SAM automatically increases the

processing capacity of the VMG by creating an additional auto-provisioned ISM MG

Card on the NE.

The threshold bearer limits are defined using an RMON policy. See the “Remote network

monitoring policies” chapter in the 5620 SAM User Guide for more information on

configuring RMON policies.

VMM automatic healing

Automatic healing on the VMM is triggered when an LSS_hostReset alarm is raised on a

VMM VNFC. The 5620 SAM first attempts a soft reboot. If the alarm is not cleared, the

5620 SAM then attempts a hard reboot. If the alarm is still not cleared, the 5620 SAM

raises a VNFCAutoHealFailed alarm on the VNFC.

The Auto Heal Timer specifies the length of time the 5620 SAM waits between reboot

attempts before proceeding with the next action.

Note: Automatic healing is not triggered if the LSS_hostReset alarm is raised on the

active OAM VNFC.

Procedure 4-3: To configure automatic scale-out or automatic

healing

Purpose

Perform this procedure to enable and configure automatic scale-out or automatic healing

for the VMM or VMG. This procedure requires system administrator access rights.

Steps

...................................................................................................................................................................................................

1 Choose Administration→System Preferences from the 5620 SAM main menu. The

System Preferences form opens.

...................................................................................................................................................................................................

2 Click on the NFV tab.

...................................................................................................................................................................................................

3 Configure the required parameters to enable and configure automatic scale-out or

automatic healing.

...................................................................................................................................................................................................

4 If you are configuring automatic scale-out for the VMM, configure the Scale Out Factor

(VMM) (%) and Auto Scale Out Timer (VMM) (hours) parameters.

The Scale Out Factor (VMM) (%) parameter defines the threshold that triggers the

automatic scale-out operation, where the threshold is the UE capacity of the VMM

multiplied by the scale-out factor.

The Auto Scale Out Timer (VMM) hours parameter defines the minimum amount of time

the 5620 SAM will wait before triggering an automatic scale-out operation while a

previous scale-out operation is still in progress. You should specify a length of time that

exceeds the expected time for a virtual MAF to become operational.

...................................................................................................................................................................................................

5 If you are configuring automatic healing for the VMM, configure the Auto Heal Timer

(VMM) (min).

The Auto Heal Timer (VMM) (min) specifies the length of time the 5620 SAM waits

between reboot attempts before proceeding with the next action.

5620 SAM VNF licensing

Overview

You can view 5620 SAM VNF license information from the 5620 SAM Java GUI. This

information includes validity status and expiry date. The 5620 SAM automatically raises

a SysLicenseExpiresSoon alarm when a license includes a valid UUID, but is less than a

week from expiring. You can view license information from the License tab on a VNF

card slot.

Usage consumption logging

The 5620 SAM allows you to track usage consumption for your 5620 SAM VNF

licenses. You can view the 5620 SAM license information by choosing Help→5620 SAM

License Information from the 5620 SAM main menu.

The 5620 SAM License form lists the following information, which you can export to a

text file, if required:

• basic system information

• licensed 5620 SAM software modules and packages

• consumed and remaining equipment license quantities

• number of allowed operator positions
