ROI Case Study: Data Access Networking for VoIP and Lawful Intercept

Published on

ISP is deploying VoIP services and must implement QoS monitoring tools to insure the network performance meets high standard of quality and execute lawful intercept.

VoIP QoS distributed probe plan is cost prohibitive because too many probes are required. VoIP phone calls involve many sub protocols which comprise of many different servers and hosts. There is no singular place to plug probes in. SPAN ports at the core miss many local transactions. The data must be collected at various points on the network. In total, 36 probes are needed totaling 2.8 million dollars.

ROI Case Study: Data Access Networking for VoIP and Lawful Intercept

  1. 1. Gigamon ROI Analysis Over $2.7M Saved by Major ISP Data Access Networking for VoIP and Lawful Intercept Customer GigaVUE + TAP solution The Worlds largest ISP offering VoIP services. The TAP links directly to the network to avoid SPAN ports. Aggregate packets from the TAPs recreate the calls and reduce Status the number of probes to one resulting in a significant savings ISP is deploying VoIP services and must implement QoS to our customer with a more robust solution. monitoring tools to insure the network performance meets high standard of quality and execute lawful intercept. Over $2.7M Saved in Capitol Expenditures • Original Plan: Use lots of probes everywhere Problem • 36 probes at $80,000 = $2,880,000 VoIP QoS distributed probe plan is cost prohibitive because • Plan B: Span port aggregation to reduce probes too many probes are required. VoIP phone calls involve many • Missed traffic flows are not acceptable sub protocols which comprise of many different servers and • Solution: GigaVUE + TAP solution = $171,000 hosts.
