Exinda Network Orchestrator 2 Getting started | 49
Out-of-band (WCCP) mode (VMware ESXi)
This configuration can be done either at a branch office with virtual infrastructure, or in the data center where the
application and local user traffic accessing the WAN is redirected to the Exinda Virtual Appliance for diagnostics, shaping,
and acceleration.
Scenario
Branch users access local services (print, DHCP, Active Directory) that are virtualized.
One physical NIC interface is dedicated for management of the virtual machines and hypervisor.
One physical NIC interface is configured on the hypervisor for LAN access, and has a routed connection to the WAN
router.
One physical NIC interface is configured and mapped to the AUX port on the Exinda Virtual Appliance.
OPTIONAL: It is possible to configure and map all data traffic through a single NIC interface on the hypervisor; how-
ever, for performance reasons it is recommended to segment the un-optimized traffic from the optimized traffic.
User access from the branch office to the Data Center applications has two paths:
Path one is directly to the WAN router, with no traffic shaping or acceleration.
Path two is through the re-directed path invoked by the router (using WCCP) to the Exinda virtual appliance.
The traffic is optimized and accelerated.
Traffic on the Data Center side has the same path as the branch side. Traffic that is selected to be optimized and
accelerated is redirected to the Exinda Virtual Appliance through WCCP on the WAN router.
The Exinda provides Diagnostics, Shaping, and Acceleration for only redirected traffic in this configuration
Use Case
Screenshot 22: Use-case for Out-of-band (WCCP) mode (VMware ESXi)
In this use case:
The virtual LAN with application servers (APP1 W2003 or 8 and APP2) are configured in the ESXi hypervisor on SW1
and mapped to NIC1. They have a direct path the WAN router.
