Thanks Alfredo I'll set up my lab environment according to your recommendations and will let you know on the outcome.
Best regards Fernando Message: 2 Date: Tue, 26 Jan 2016 21:39:27 +0100 From: Alfredo Cardigliano <[email protected]> To: [email protected] Subject: Re: [Ntop-misc] Traffic aggregation and distribution at wire-speed Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Hi Fernando if you have to send a full copy of the aggregated traffic (fanout) to all the 4 egress interfaces you can use zreplicator, if you have to load-balance the aggregated traffic to the 4 egress interfaces, you need an extended version of zbalance_ipc (it should open physical interfaces instead of egress queues) As of the hw to use, I can recommend any igb-based Intel card (e.g. i350). A 8-port or 2x 4-port should perform the same.
