Configuration / Traffic Policies
« on: March 16, 2014, 02:13:34 PM »
Traffic policies are optional in a standard point to point network, but recommended to ensure only the intended traffic gets optimized.

In a point to multipoint network, when some remote sites don't have Wanos devices, a Traffic Policy is required to by-pass these sites. For example in the following network, only one remote device is placed in the network at one site. Since there are multiple remote sites rule #98 and #99 are created:

What about UDP Optimization?

Yes, both deduplication and compression for UDP is available from version 1.2.1.

FAQ / Change IP address from the Command Line

How do I change the IP address from the command line? (e.g. No access to the Web GUI)

Run the command: wanos-cfg

Which Network Interface Cards are supported?

Generally most common generic cards are supported by default.

Pleasure... thanks for the great feedback. When connecting the appliances back to back without a WAN, the WAN Simulation can be enabled. This rate limits the wan0 interface to 1 Mbps, which is useful in a lab to see the difference with optimization enabled/disabled.

FAQ / Re: High Availability - Bypass
« on: March 10, 2014, 04:46:34 PM »
Extract from: UPDATED: High Availability

High Availability or redundancy can be achieved by running a backup network cable parallel to the Wanos device. When running RSTP the Wanos Core device is placed between two switches, connected via wan0 to the outside switch and lan0 to the inside switch. The backup link is cabled between the same two switches. RSTP should elect the primary and secondary path based on the port id. Ensure the Wanos link is on the lower port number or configure the switch to make this link the primary path. RSTP should place the backup link in an alternative path status and will switch over to the backup link within a few milliseconds of detecting a loss.

When running Per-Vlan RSTP high availability can be achieved using a single switch. In this case two VLAN's are created. The Outside VLAN connects the WAN segment and the Inside VLAN connects the LAN segment. In the diagram below, the Router, Wanos wan0 and the backup link is connected to VLAN 10. On the LAN side the Wanos lan0, Data LAN segment and the backup link is connected to VLAN 20. Under normal conditions the Wanos device bridge traffic between the two segments and the backup link is passively idling. When the switch detects a failure on the primary path, the backup link is enabled and immediately placed in the forwarding state. Advance features like loop guard and hello timers can be adjusted to improve convergence times.

Example Cisco Switch Config:
spanning-tree mode rapid-pvst
interface fa0/1
description WAN-Router
switchport access vlan 10
spanning-tree mode access
interface fa0/2
description Cross-over-fa0/5
switchport access vlan 10
spanning-tree mode access
interface fa0/3
description Wanos-wan0
switchport access vlan 10
spanning-tree mode access
interface fa0/4
description Wanos-lan0
switchport access vlan 20
spanning-tree mode access
! Primary Link via Wanos lan0
spanning-tree cost 1
interface fa0/5
description Cross-over-fa0/2
switchport access vlan 20
spanning-tree mode access
interface range fa0/6 -24
description LAN
switchport access vlan 20
spanning-tree mode access

Without the Core, the Edge is just happily passing traffic through. The few Mb's detected as saved is probably a false positive due to traffic generated from accessing the GUI. A minimum of two appliances are required to get optimization going. If you have another appliance, you could connect the Core and Edge back to back as an initial test.

Installation / Re: Installing.

Yes, it seems that the onboard nic is not detected, hence the bridging is not coming online. This is driver related. If you have the exact specs of the onboard nic, it might be possible to revive it.


Note: Try to use Intel based NICs when possible.

FAQ / Wanos Open Source Wan Optimization
« on: March 08, 2014, 04:18:14 PM »
Is Wanos open source?
Can I have the source code?
Can I modify the source code?

Wanos Express versions released free will always be free, but not open source wan optimization per se. Opensource and Wan Optimization enthusiasts that are interested in contributing and making the technology more accessible are encouraged to get in touch.

Companies looking to integrate wan optimization into their feature set, should please have a look at the OEM Wan Optimization option.

How to help?
  • The easiest way to help is to simply start using wanos. Deploy in a network and let us know what the most essential next feature is.
  • Tell a friend, colleague, anyone that can benefit from wan optimization.
  • Wanos working well in your network scenario? Great, post the results.
  • Tell us about your hardware in the hardware section
  • Found a way to deploy the solution that has not yet been documented? Fantastic, let us hear about it and someone might benefit from this contribution.

Want more?
Developers, Linux and Networking skills are very valuable. Please get in touch.

FAQ / Hardware limits (Wanos Express vs Wanos Plus)
« on: March 06, 2014, 11:21:00 AM »
Note: This info is probably outdated. Please see our Wan Optimization Products page for up to date info on Express. Recently additional features have been enabled and more bandwidth added.


Wanos Express (Free)
What is the minimum required RAM? 2GB
Max optimized remote sites? 1
What is the required disk space? 64Gb
What is the most important for peak performance? 1) CPU processing power when set to 'high'. 2) Disk IOPS (SSD)
Will adding more RAM make a difference? Yes, frequently used byte patterns will be buffered in memory

Wanos Plus
What is the minimum required RAM? 2-4 Gb
What is the maximum RAM? 64-256 Gb
Max sites? Depending on hardware & configuration 1 - 512
What is the minimum required disk space? Minimum 64 GB
