Ÿ 6WINDGate™ packet processing software improves

performance of standard Open vSwitch (OVS) by over 10x

Ÿ No changes required to OVS

Ÿ Can be combined with 6WIND’s Intel® DPDK extensions and

fast path protocols

6WIND provides software solutions that address critical networking

performance challenges in data centers. In the use case outlined

here, the 6WINDGate™ packet processing software accelerates

Open vSwitch (OVS) instantiated on an application server blade

and conﬁgured using OpenFlow, delivering a performance

improvement of over 10x thanks to its optimized data plane

architecture.

OVS is widely used by open source hypervisors to perform

switching for virtual machines (VMs). However, it experiences

bottlenecks due to the Linux kernel networking stack. 6WINDGate

can accelerate the virtual switch function by 10x without any

change to OVS, or the OS, hypervisor or OpenFlow Controller.

6WINDGate software adds its own networking stack and poll mode

drivers on top of Intel® DPDK, including Layer 2-4 protocols such

as VXLAN, Filtering/NAT and IPsec in addition to basic switching

features.

In 6WINDGate, critical networking functions are performed in a

fast path environment outside the Linux kernel. 6WINDGate OVS

acceleration delivers high performance, reaching 195 Gbps

throughput. This performance is achieved using Mellanox

ConnectX®-3 Pro 40G NICs plugged on an HP ProLiant server

running Red Hat Enterprise Linux and tested with an IXIA 40G

trafﬁc generator. 6WINDGate includes 6WIND’s Mellanox poll

mode driver (PMD) for the Intel® DPDK.

Overall performance is required no matter the architecture (legacy,

SDN, NFV). Delivering performance without impact on the

environment (OVS, OS, hypervisor or OpenFlow Controller)

provides a solution to implement a smooth and incremental path to

new architectures.
