Utilizing Enterprise Edition Appliance to Provide WAN
Optimization Services Only

Nov 24, 2016

The SD-WAN Enterprise Edition appliances contain fully featured WAN Optimization functionality in addition to WAN
Virtualization. Some customers prefer to implement WAN Optimization functionality before migrating to SD-WAN services.
This deployment use case provides the steps to utilize Enterprise Edition appliances to utilize WAN optimization services.

NetScaler SD-WAN Product Platform Editions include the following appliances:

SD-WAN: SD-WAN Standard Edition appliance
Enterprise: SD-WAN Enterprise Edition appliance
WANOP: SD-WAN WANOP Edition appliance

To integrate Enterprise Edition appliances into an existing distributed WANOP network, you need to conﬁgure SD-WAN
(Physical or Virtual) appliance at the DC site as the MCN. The SD-WAN appliance manages all conﬁguration of the network.
A Virtual Path is established between the Branch site and MCN at the DC site. This Virtual Path is only used for sending
control trafﬁc between the appliances. At the branch appliance, the data trafﬁc is processed as an intranet service. The
intranet trafﬁc is not encapsulated and traverses over existing WAN link to reach the DC site. A WANOP appliance at the
DC site needs to be in the trafﬁc path to provide end-to-end trafﬁc optimization.

For customer sites that do not have SD-WAN hardware appliance at the head-end, VPX appliances in a HA pair (two Virtual
WAN VPXs) can be used as MCN in one-arm mode. For the one-arm mode, PBR rules on the third-party router are required
to redirect trafﬁc to the SD-WAN appliance.

This document assumes that the DC site appliances are deployed in HA mode for redundancy. However, note that HA
mode is not mandatory for this deployment

Prerequisites

A pair of WANOP appliances and a pair of SD-WAN appliances deployed in HA mode at the DC site.
An Enterprise Edition appliance at the Branch site.

SD-WAN St andard Edit ion and WANOP Appliances in PBR Deployment

SD-WAN St andard Edit ion and WANOP Appliances in PBR Deployment

In the below illustration, both the SD-WAN SE and WAN OP appliances at the DC site are deployed in one-arm mode. The
SD-WAN appliance supports PBR deployment while the WANOP appliance supports both PBR and WCCP. The control
trafﬁc (Virtual Path trafﬁc) received from WAN at the DC site will be redirected to the SD-WAN appliance by the PBR
Router. The data trafﬁc will be redirected to WAN Optimization appliance by the PBR Router.

Trafﬁc ﬂow for WAN to DC LAN:

CE (Customer Edge) Router -> PBR Router -> SD-WAN -> PBR Router -> LAN
CE (Customer Edge) Router -> PBR Router - > WAN OPT - > PBR Router- > LAN
