Combining NetFlow and packet analysis boosts network visibility
This article is part of the Network Evolution issue of February 2012 Vol. 3, No. 1
Now that Blue Cross Blue Shield of Minnesota relies on Software as a Service (SaaS) for core business processes like administering claims, network performance engineer Barry Pieper relies on deep packet analysis to tap inbound and outbound Internet traffic in order to ensure his providers are delivering on their service-level agreements (SLAs). But it wouldn’t be worth using costly deep packet inspection for all of his network monitoring needs, so Pieper still turns to good old fashioned NetFlow analysis for a broader view of what’s happening on the network. Combined, Pieper uses a Network Instruments Gigastor appliance for packet capture, Compuware’s Vantage network monitoring product— recently rebranded as Gomez Network Performance Monitoring—for analysis of that packet information, and then Fluke Networks’ Optiview NetFlow Tracker for NetFlow. “I use NetFlow a lot on our wide area network mainly because it works so well there,” he said. “Our branch offices are T1 and T3 links, so we would do software distributions with ...

Military radar may cause fixed broadband wireless interference. This expert tip explains tests and ideas to check if this is the case and how to address this interference.
Network bloggers have a lot to say, but do we care? We should. In the top ten network blogger opinions of 2011, our experts poke holes in TRILL, OpenFlow and 10 GbE optimization.
Migrating to 40 GbE will require network performance testing that will take into consideration backplane throughput, jitter and the needs of an FCoE environment.

Packet analysis may provide a deeper look into the network, but NetFlow analysis can offer a broader view. To achieve even better network visibility the two work best together.
Until now the DevOps movement has been lead by systems administrators, but now network engineers may find it also eases network automation and cloud orchestration.
