Project Name(s) Verizon Call Drop Analysis, Decision Tree Build & Log Viewer
Client Name Verizon Wireless
Role Hadoop Technical Lead
Description
Log files generated by select mobile phones placed all around the US of A provide
key information with respect to the telecom network. Each log file generated
everyday has a size >10 GB. These log files need to be analyzed in hadoop cluster
on the key parameters provided and the captured data has to be moved to a
SQL/NoSQL system for data visualization. The unstructured data is extracted,
transformed and loaded to the SQL/NoSQL by using big data hadoop as the
backend.
Requirements for each project:
Call Drop Analysis:
Query the SQL/Hive for call drops and build various visualization dashboard charts in
tableau.
Decision Tree Build: Built a decision tree for each call drop for its root cause.
Log Viewer: Web UI for viewing the entire log file data by KPI groups.

GMRE Network Analyzer is a non-service impacting tool to collect
network data of GMRE nodes from GMPLS networks. The tool is capable of
supporting multiple networks data collection and processing. The tool is
based on client-server architecture. Client (GUI & CLI) can be run on
Windows & Linux environment and server (Data collecting server or DCS) on
Linux & HP-UNIX environments. The DCS collects the GMRE node’s logs and
snapshot files from the network periodically as per user scheduled time
configured and stores on a centralized server. The collected data is parsed
and ported on to the DCS database. The DCS ensures consistency of the
periodically collected data from the network so that the data at any instance
of time is available from all the network elements of the networks.
