SDN management battle: TAPs vs. network packet brokers

Jim Duffy | March 31, 2015
New SDN management tools emerge to overcome limitation of legacy network products.

But NPBs also rely on TAPs as a data source, Harding says. In that respect, they'll remain complementary despite each device attempting to leapfrog the other in functionality.

"One of the biggest value propositions of [TAP] is the affordability of deploying a broad fabric at low cost on bare metal switches," says EMA's McGillicuddy. "That's something you're starting to see the network packet broker vendors co-opt. Network packet brokers are basically turning OpenFlow switches into TAPs. So TAPs rely on network packet brokers for advanced features; network packet brokers rely on TAPs for bare metal."
