Nokia Siemens
Networks NetAct™
For Accedian
Mobile Broadband Ethernet
and IP Service Assurance
Understanding
the user experience
is the key to customer loyalty
Providing an excellent customer
experience is essential for operators
that wish to succeed in todays
highly competitive markets.
Customers expect to use their
chosen mobile services whenever
and wherever they want. Operators
will only be able to maintain ARPU
and customer loyalty by meeting
these expectations. In other words,
the drive for quality of service and
quality of experience must lie at the
heart of every operator’s business.
NetAct OSS5.4 CD2 introduces
Ethernet and IP service assurance
monitoring and reporting with the
Accedian MetroNID® and
MetroNODE 10GE™ packet
assurance demarcation units.
Accedian Networks’ High
Performance Service Assurance™
platform is a complete service
creation and assurance suite for
MetroNID® and MetroNODE 10GE™
packet assurance demarcation units.
Accedian’s platform makes it easy
for service providers to establish
and assure demanding mobile
broadband LAN services carrying
QoS-sensitive VoIP, video and
control plane traffic.
With a comprehensive suite of active
and passive in-service performance
testing, intelligent layer 1-4 loopback
functionality, and per-flow monitoring,
NetAct enables e2e visibility of the
services within the mobile broadband
network.
Installed in-line service at cell-sites,
aggregation hubs and mobile switching
centers, MetroNID and MetroNODE
10GE units define the boundaries of the
network and services without impacting
customer traffic.
Accedian Networks Performance
Assurance Agent™ (PAA) monitors
critical SLA parameters and generates
a sparse but continuous stream of
time-stamped Y.1731 test packets
between MetroNID and MetroNODE
10GE units which use a patent-pending
in-band synchronization technique to
provide one-way, end-to-end delay and
delay variation measurements to
microsecond resolution.
The Performance Assurance Agent™,
PAA™, is hardware assisted active
measurement function that computes
layer 2 or 3 (IPv4) network delay
(latency), delay variation (jitter), packet
loss and continuity check. It operates by
sending active probes to a peer device,
which sends back replies containing
timing information. No upper layer
protocol, such as TCP, is used. Each
peers then computes various metrics.
The PAA™ does this operation on a
continuous basis.
The PAA also measures frame-loss and
monitors service availability in
point-to-point, point-to-multipoint, mesh
network topologies and multicast
services.
Each MetroNID unit can create up to 100
test streams to other units or up to 1,000
with the MetroNODE10GE, each with
specified flow characteristics. PAA
packets are tagged with specified
customer / provider VLAN ID, service
level and bandwidth class to precisely
capture the behavior of multiple SLA
flows in real-time.
The characteristics of the test packets for
each flow is set to match the layer 2 (P-bit
of VLAN tag) or layer 3 (IP ToS/DSCP
value) characteristics of the services
being monitored. These packets may be
independently destined to different peers
or to the same peer, using different class
of service (CoS) and/or VLAN ID as
appropriate. Up to 2 VLAN tag can be
specified.
Network delay and delay variation are
calculated for both one and two way
directions. For each metric, the current
result (last computed metric), average,
minimum and maximum values as well
as previous average, minimum and
maximum values are available.
In the case of the packet loss the
receiving peer computes the current and
previous averages using the received
test packets. Finally, the receiving peer
performs continuity check, using the
received test packets.
The PAA™ agent verifies the results
against programmable thresholds and
generates alarm indications as needed,
Operator benefits
• View service and network performance from
the customer perspective
• Reduce costs through rapid problem detection
and prioritization according to potential service
impact
• Analyze service usage to understand trends
and maximize revenue
• Respond more quickly to customer complaints
e2e visibility
and common OSS applications
ensures network availability
NetAct Accedian Agent
The NetAct solution includes a
software component known as the
Accedian Agent. The Accedian
Agent is a mediator between NetAct
and the Network elements to be
managed The Agent is developed
using the Nokia Siemens Networks
Java based O&M Agent that is used
for other NetAct integrations.
The Accedian Agent provides
functionality to discover the
MetroNID, MetroNODE 10GE units
and configured Layer 2 and Layer 3
services (circuits) based on IP
address range input. Once
discovered the devices and circuits
are uploaded to the NetAct database
with one operation.
Fraud
analysis
Vehicular
management
Data WH
Each device and L2/L3 circuit is a
managed object with NetAct. The
circuits are assigned a unique NetAct
ID based on the name of the circuit
configured within the device.
NetAct Monitoring
NetAct monitoring applications are
used to display the network topology
and process/view fault and event
data.
Nokia Siemens Networks NetAct™ provides flexible view
creation with Layer 2 Ethernet and Layer 3 IP service
visibility
The NetAct graphical views are
easily adjustable to the different
monitoring needs from network-wide
monitoring to the element and circuit
level, In the upper level views users
can quickly see the general alarm
situation of the managed network.
Moving to a sub-view shows the
alarming objects. Network views can
contain elements from a single
technology area or can be created to
show the e2e physical network
connectivity and L2/L3 circuits
helping with fault detection, isolation
and restoration of service time.
NetAct Alarm Monitor
The NetAct Alarm Monitor application presents
the active alarm situation of the network as a
sorted list. The sorting of the list is based on the
alarm severity class and alarm time stamps
(generation time of alarms in the element or their
insertion time into the NetAct alarm database).
Alarm Monitor provides the operator with the
possibility to acknowledge and cancel alarms,
launch additional applications and to open the
related Alarm Manual page for further details on
the alarm or actions to be taken.
NetAct Alarm History
Alarm history handling provides the user with
means to investigate the possible causes of faults
to gain a clearer understanding of the general
status of the network system and the nature of the
problems that are active. After the alarm
information is collected and monitored in NetAct,
the user can carry out an analysis of the fault
situation by performing various user-defined
searches and queries to the alarm database.
NetAct Alarm Correlation
NetAct Alarm Correlation reduces manual alarm
handling and the workload of monitoring
personnel by automating the management of the
alarm flow. You can implement operator-specific
correlation rules to best suit your needs.
Element Manager Launch
NetAct Element Manager Launch enables the
User to select from a command line interface
session or web based user interface that provides
the ability to execute Configuration Management
tasks. These tasks include initial device
configuration, configuration changes, service
provisioning and test, software upgrades and
configuration back-up.
Using the Element Manager launch, the user is
able to view the current status of the PAA results
in real time including one and two way delay,
delay variation and packet loss.
Key Features
• Discovery of L2 & L3 services configured in the
mobile backhaul and Core domains
• Real-time fault status monitoring with CFM
• SLA violation threshold crossing alerts for delay,
delay variation & packet loss
• Network wide views covering Radio Access,
Mobile Backhaul and Core
• Cross domain alarm correlation
e2e reporting
and common OSS applications

SLA Assurance
In addition to the service assurance
capabilities provided by the NetAct
Monitoring applications for Accedian,
the solution enables NetAct
Reporting applications to collect and
Report on key performance criteria to
ensure SLA’s are not violated.
NetAct Fault Management Reports
Fault management reports (FM
Reports) provide the user with a web
based interface to see snap shots of
the fault status at any given time. The
statistical survey of alarms provides
information that allows the user to
identify problems in the network, and
to take corrective actions to improve
the network performance. The user
can define the scope of the report, for
example, the time frame or the
network elements and L2/L3 circuits.
Alarms can be selected by alarm
class and alarm status (active, or all
alarms).
Report Builder
Report Builder is the central
application of the NetAct Reporting
system. It allows the user to:




Create and manage KPIs
Create and manage reports
Manage the permissions to
access data
Run reports.
The easy-to-use graphical user
interface and the use of a report
creation wizard enables even
inexperienced SQL users to create
ad-hoc reports with the NetAct
Report Builder.
This application is designed to run a broad range
of different reports on the performance data of
different network technologies. Although it is
possible to use the NetAct Report Builder for
ad-hoc queries for example for troubleshooting,
the main purpose is to administer the reporting
environment.
Reports for Accedian include support of the PAA
and Service OAM performance indicators:

Report Explorer
NetAct Report Explorer combines the functionality
of NetAct Report Browser and KPI Browser. The
Report Explorer is a web interface, acting also as
a reporting portal. NetAct Report Browser allows
viewing any report created with Report Builder.
Also URL links to other reports and sources can
be included to the reporting portal.
NetAct Report Explorer can provide the same
report to several different user groups by running
the reports on a daily, weekly or monthly basis, or
generating summary reports. The tool allows
operations like sorting of the resulting data rows,
or changing the time selection of a given report.
NetAct Report Explorer allows easy access to
management level information, and it also serves
as a starting point for detailed troubleshooting.
