Subject: [dpdk-dev] [v2 22/23] Packet Framework IPv4 pipeline sample app
Date: Wed, 4 Jun 2014 19:08:38 +0100 [thread overview]
Message-ID: <1401905319-8882-23-git-send-email-cristian.dumitrescu@intel.com> (raw)
In-Reply-To: <1401905319-8882-1-git-send-email-cristian.dumitrescu@intel.com>
This Packet Framework sample application illustrates the capabilities of the Intel DPDK Packet Framework toolbox.
It creates different functional blocks used by a typical IPv4 framework like: flow classification, firewall, routing, etc.
CPU cores are connected together through standard interfaces built on SW rings, which each CPU core running a separate pipeline instance.
Please refer to Intel DPDK Sample App Guide for full description.
