Principal Quality Analyst
Project Name : BRIXWORX
Description : The BrixWorx software engine is an ideal service assurance
and performance management solution for carrier and provider environments,
and is responsible for provisioning and managing a network of performance
test points called Brix Verifiers. Administrators use the Web-based
BrixWorx Operations Center to completely control all aspects of system
operation-from the specification of service-level objectives, to scheduling
tests, configuring Brix Verifier settings, and creating detailed
performance reports.
In addition, BrixWorx provides automatic service-level auditing and
compliance analysis, sophisticated real-time and historical reporting
capabilities, integration APIs, and storage for performance data.
Roles and Responsibilities:
. Defining the scope of testing, Planning, deploying, and managing the
testing effort for any given engagement / release.
. Involved in different types of Brix Verifier's configuration,
Installation of Brixworx test set up.
. Designed and implemented entire Lab set up as a private network.
. Track and prepare the report of testing activities like test testing
results, test case coverage, required resources, defects discovered
and their status, performance baselines etc.
. Test Execution of service active tests, Network active tests and
passive tests for different VOIP calls like H323, SIP, MGCP, H248,
RTP, NCS...etc and verified the performance (RTP packets statistics,
Call performance statistics and MOS degradations) of calls.
. Monitoring and capturing different VOIP calls data from network
traffic using passive verifiers.
. Test execution of Brixworx applications like Ping, HTTP active,
TCP/UDP echo test, DNS active, FTP active tests and verify network
statistics (Latency, Jitter, RTP Statistics, Call Measurements... etc)
for all applications for six (Release 7.2, 8.0, 8.1, 8.2, 8.3, 8.3.1,
8.4, 8.5 and 8.6) regression cycles.
. Tested the functionality of the Expert VoIP Test Tool application to
generate VoIP calls (SIP, H323 and H248) from EXFO's FTB-1 platform to
another EXFO FTB-1 platform or any IP phone.
. Expert VoIP Test Tool : Test execution of H323 service active test,
H248 service active tests, SIP Service Active Test, SIP Network Active
Test (RTP statistics and call performance statistics, MOS
degradations) on Expert VoIP Test Tool Application
. Expert IP Test Tool: Test Execution of Ping, HTTP Availability, FTP
Performance, VLAN Scan and LAN Discovery Tests on Expert IP Test Tool.
. Verified NID (RAD, MRV and Raisecom) devices Integration with BrixWorx
using SNMP: NID Integration with Brixworx is providing more visibility
into network topology, network elements inventory, network performance
and network capacity a very efficient approach is to gather
information and metrics from the devices already present in the
network. It is an extensible SNMP engine to be included and used for
SNMP polling/provisioning and integration capabilities.
. Verified the Jaguar application (Bytesphere) is polling the values
from SNMP devices during the discovery using SNMPv1, SNMPv2c and
SNMPv3.
. Executed the discovery of 10,000 RAD devices with SNMP protocol using
WebNMS simulator tool
. Port Basis Test: Tested the Port and Interface counters that provide
utilization and error metrics (Tx/Rx frames, frames size, error frames
like CRC error frames, oversized frames etc).
. Flow Basis Test: Tested the traffic conditioning counters that provide
information on queuing, shaping, and/or policing functions that are
applied to the traffic carried by an EVC.
. Verified the traffic classification counters that count the number of
frames and bytes sent and received by specific classes of flows
. Verified the statistics like the percentage of frames
(Green/Yellow/Red) discarded because the traffic conditioner decided
they exceeded the EIR and EBS set for their COS within this EVC.
. OAM Test: Test execution of OAM test and measure the frame statistics
like Frame loss, frame delay, frame delay variation based on OAM test
configuration.
. Test execution of Interface test, CPU Utilization Test, Memory Test
and Storage Test.
. Understanding and developing the system level functional test plans,
Execution of test cases, Defect detection, reporting, tracking the
issues along with prioritization and impact analysis of the defect.

Solution
Description : EXFO Xtract is an extensible monitoring system that is
capable of monitoring large number of devices and technologies. EXFO Xtract
discovers IT assets, collects data, monitors, and alerts you of any
potential issues. Events are generated based on configurations for
exceptions, syslog, and trap filters. These events are normalized and can
be categorized into groups, organizations, or monitored capabilities.
