SESSION MANAGEMENT IN AN ENTERPRISE COMUNICATION NETWORK
• Alarms and Events affecting the service
• Centralized Provisioning and maintenance
• Generating reports for business and network planning
tasks
• SDR management
The GENView RSM also includes the following task-specific
modules:
• Route Analysis Module (RAM) – the RAM running
on the GENView RSM server processes SDRs in real-time
from multiple SBC platforms and is used to determine
QoS. This is the fundamental component by which
the RSM Agent communicates with the SBC. The RAM
provides a basic set of engineering reports including the
Answer Seizure Ratio (ASR), listing of 200 most recent
calls, and enables custom reports to be specified.
• Events and Statistics Module (ESM) – the ESM
facilitates alarming which can be syslog based or SDR
based. SBC log files are parsed for specific error codes
to trigger alarms. Similarly, SDR information (e.g. error
response, ASR threshold, total number of minutes, etc.) is
used to assess event and alarm generation. Action taken
includes logging the error to a file, generating an email
to the network administrator, or blocking a particular
endpoint via the Adaptive Routing Module.
• Adaptive Routing Module (ARM) – the ARM
provides a set of actions to change the route table configuration
on the SBC. The ARM provides a mechanism
to disable calls at endpoint ingress or egress based on
alarm conditions and network capacity states.
• Business Analysis Module (BAM) – the BAM
processes SDRs from the RSM database to produce ondemand
business reports. These include usage and cost
by route, sector, etc. The RSM provides hooks to external
billing and accounting systems via its Web Services
(WSDL) interface.
• Web Interface Module (WIM) – the WIM provides
user access via a web interface for which the user is
authorized. Subscribers may be set up with portal access
for self-care purposes, controlled and secure in their
group or department. In cases where the RSM is shared
between multiple groups, known as partitioning, the
WIM restricts user views to their respective partitions.
Note that there is no limit to the number of user per
partition or number of access lists.
• Least Cost Routing Module (LCR) – LCR generates
routing rules based on BAM rating information. The LCRgenerated
routes are then used to reconfigure the route
tables in the SBC to effect the required changes.
• Third Party SDR Support Module (TCS) – the TCS
enables importing of third-party SDRs into the RSM for
reporting/rating and exporting to third-party database
directly from the RSM. Under partitioned conditions, only
SDRs that belong to that partition are streamed.
RSM Reports
The reports generated by the GENView RSM enable network
administrators to monitor system activity in real-time for technical
and business purposes. Engineering reports display the ASR in
various formats, or a list of the last 200 calls can be displayed.
Up to 11 types of reports can be generated which are colorcoded
based upon ASR percentages, and a graph generated
of ASR against time. Calls are grouped and color-coded into
abandoned, busy, error or normal status categories with each
individual call and detailed SDR information available. The
report provides operational staff insight into network health and
the ability to analyze issues on a call-by-call basis. Reports can
also be filtered based upon parameters such as the SBC host
platform, start date, end date, source ID and destination ID. The
report can be set to periodically update and display via the
web interface. An example engineering report generated by the
GENView RSM is highlighted below:
