External Storage System Overview
Cisco ASR 5000 Series External Storage Server Installation and Administration Guide ▄
Figure 1. ESS Architecture with ECS
The system running with ECS stores xDR files on an L-ESS and billing system collects the files from the L-ESS, and
correlates them with the AAA accounting messages using either 3GPP2-Correlation-IDs on a PDSN system or Charging
IDs on a GGSN system.
L-ESS also pushes xDR files to external applications for post-processing, reporting, subscriber profiling, and trend
analysis.
Local, Short-Term External Storage System
The Local, short-term storage system (L-ESS) is a storage server logically connected with the ASR 5000 and acts as an
integrated network system.
The following are the requirements for the deployment of L-ESS:
High speed dedicated redundant connections to chassis to pull xDR files.
High-speed dedicated and redundant connection with billing system to transfer xDR files.
