Seven years ago at LCA, Van Jacobsen introduced the concept of net channels but since then the concept of user mode networking has not hit the mainstream. There are several different user mode networking environments: Intel DPDK, BSD netmap, and Solarflare OpenOnload. Each of these provides higher performance than standard Linux kernel networking; but also creates new problems. This talk will explore the issues created by user space networking including performance, internal architecture, security and licensing.]]>
