Virtual Networking Performance in OpenStack Platform for Network Function Virtualization

Figure 18

Received throughput versus generated packet rate for each tenant (T1, T2, T3, and T4) when T1 does not traverse the VNF chain of Figure 7(d), with -byte IP packet size. Comparison with the single tenant case. DPI: deep packet inspection; FW: firewall/NAT; TS: traffic shaper; VR: virtual router; DEST: destination.
