How One of the Biggest ISPs in India Achieved DoT Compliance with Trisul IPDR: A Success Story
Executive Summary
A leading Indian Internet Service Provider (ISP) with over 20 million customers faced significant challenges in complying with the Department of Telecommunications (DoT) regulations. The ISP required a comprehensive solution to collect, store, and manage IPDR and NAT logs. Trisul IPDR was deployed to address these challenges, providing a scalable and easy-to-use solution. As a result, the ISP reduced costs, improved customer satisfaction, and ensured seamless compliance with DoT regulations.
Background
The ISP catered to a vast and diverse user base across India, with over 20 million residential and business customers. To comply with DoT regulations, the ISP needed to collect and store specific internet session data, including IPDR parameters and NAT logs.
Challenges
To better understand the complexities of network log data management, let’s examine the key challenges the ISP faced. This analysis will help pinpoint areas for optimization and improvement in your own operational infrastructure.
Manual Log Management
The ISP previously relied on storing log files in tables and flat files, which made querying a cumbersome process. Retrieving specific data required manually grepping through massive amounts of data (gigabytes) that took hours to complete. Moreover, combining log data with AAA records involved labor-intensive manual work. Manual handling errors could lead to loss of IPDR logs and non-compliance penalties.

Integration with AAA Records

NAT and CGNAT Correlation
Picture this: a large-scale ISP, heavily reliant on NAT and CGNAT. Now, imagine trying to make sense of it all – correlating private IPs with flow logs, that is. Sounds like a daunting task, right? Well, that’s exactly what our customer faced… until they found a simple yet powerful solution: directing CGNAT Flow Translation NetFlow logs from the LSN (Large Scale NAT) router straight to Trisul, enabling automatic correlation of the private IPs with the flow logs.

Sheer Size of the Log Database
This particular ISP was doing 2-3Tbps traffic. Their existing solution was not scalable and can’t handle the sheer volume of IPDR and AAA flow records and queries, leading to performance issues, frustrating delays, and a subpar user experience.

Requirements
To address these challenges, the ISP required a solution that could:
- Ensure full compliance with DoT regulations
- Collect NetFlow data from 30 gateway routers
- Integrate with existing AAA and NAT systems
- Provide High Availability (HA) mode to ensure uninterrupted service by automatically switching to a redundant system in case of failures, minimizing downtime and data loss.
- Offer secure Tape Backup for long-term data retention, protect against data loss due to hardware failures or natural disasters
