Versatile Data Mediation Platform

OSSera Data Mediation Platform provides a set of drag and drop components to process:

  • incoming alarms, metrics, Call/Signaling Data Records, Inventory Retrieval, and
  • bi-directional command and response interactions (i.e.: Testing, Activating, Re-configurating, Pings, etc...)

The Data Mediation Platform has collectors for standard interfaces as well as tools for users to develop user-specific data collectors. These data collectors can collect and process data in any format.  For example, OSSera's Fault Management framework uses these alarm data collectors to collect and pre-process raw alarm data from NE/EMS/NMS or any other entities.  

Multi-Protocol

OSSera's Data Mediation Platform (DMP) supports SNMP, Socket, File, and Corba with supporting Managed Information Base (MIB) Loading tools and ID/Parse rules for non-SNMP protocols.  Data from various protocols are normalized into a standardized Flow Builder.

Flow Builder

Flow Builder is a drag and drop tool which allow the user to create states.  States model the input, ID, Parse, and Error states of the data flow.  Also users can model output, final, transition, and final states of the flow.  This streamlines the process in managing resources across a wide domain.

Control Flow

Action States are implemented for applications such as Advanced Troubleshooting where commands are sent to various managed resources for testing, pings, and retrieving data.

 

Debugging Mode

From experience the process in managing Data Mediation can be painfully cumbersome.  Debugging features have been added including breakpoints, stepping, value checks, and flow animation to make sure DMP functions have been implemented correctly in building adapters.

Deploy and Execute Flows

Flows are packaged and can be installed with an installer for ease of distribution across a carrier's network.  Once deployed they can be executed to run.

A Unified Data Mediation Platform

Using the OSSera platform as a foundation the DMP automates interactions critical for Advanced Troubleshooting, Fault Management, Performance Management, Service Problem Management, Service Quality Management, Inventory Retrieval/Resource Management, and Customer Experience Management/CDR Service Usage Management.

Advanced Troubleshooting - a Unified Approach to Resource and Service Problem Management

Troubleshooting can be very complex.  Service Level Agreements specify critical Mean-Time-To-Repair (MTTR) objectives which must be met.  Call Center, NOC, and Engineering costs need to be managed and time spent on troubleshooting can be very time consuming.  A unified approach to resource and service problem management is required.

Problem:

  • Troubleshooting problems can take time and has a direct impact on Customer Satisfaction and MTTR. 
  • Often hold times for customers can be several minutes and is very costly to OpEx as this equates to more Customer Care reps to handle call volumes
  • Sometimes the knowledge for troubleshooting resides only in a few experts within the Call Center, NOC, Field, and Engineering.
  • Troubleshooting and testing may extend for several days as automated tests are required for NOC Engineers and Support.
  • Call Centers can be distributed geographically and very large in number - authorized access is required.
  • Role-Specific commands are required

Solution:

OSSera's OSS Explorer platform is being leveraged across 1700+ Customer Care users for Advanced Troubleshooting (AT) of ADSL.   Below is a process flow:

  1.  Users will Call into the Call Center Operator - The NOC Engineer also has role-specific authorized access to the AT interface for troubleshooting.
  2. The Call Center Operator has access to the the AT interface to access role-specific authorized troubleshooting commands.  A ticket may be openned and passed to the NOC Engineer for further troubleshooting.
  3. Commands are selected on the client and triggered to run on the OSS Explorer multi-threaded symmetrcially distributed platform.  Scheduling of commands is also available.
  4. The DSLAM/EMS equipment are tested
  5. The user at home is also checking on the ADSL modem per direction from the Call Center Operator to make sure it is appropriately connected.
  6. The ADSL Modem is connected to the DSLAM/EMS and results are fed back to the NOC or Call Center Operator
  7. The DSLAM is connected out to the Internet successfully after troubleshooting.

Below is a high-level view of the CRM Tier 1 Call Center interface.

Also below is a view of the NOC role-specific AT interface.

Scheduling troubleshooting commands will help to resolve intermittant problems and also time sensative issues during peak hours.

Key takeaways on our AT solution:

  • 1000's of Clients supported
  • 99.999% symmetrically distributed system
  • multi-threaded
  • transparent upgrades
  • Secure authorized client application
  • Role-specific interfaces
  • Experience and support for various ADSL vendors.
    • Alcatel ATM & IP
    • Datang
    • Fujitsu ATM ST1AC, IP GbeTrunk, IMA 8, IMA 16, STM1 8, STM1 16
