just information to share
It is only my test
udp start dropping packets(with following iperf cmd):

General Discussion / time delay on wanos appliance
« on: May 04, 2015, 11:24:02 PM »

Since optimization itself takes time,
I am just wondering  how much time wanos will spend on processing a packet for optimization in general ( compared to a wire without optimization )

Or how can i give a test to see it ?


Features / traffic policy missing ip and port pair
« on: April 17, 2015, 07:53:29 AM »

We have situation that certain traffic between two IPs need to be bypassed.  But,existing traffic policy seems missing port option.
Please help out and thanks very much.

Configuration / simple udp optimization setup help
« on: March 09, 2015, 01:51:28 PM »
I am trying to get simple udp optimization working with version 2.0.2. 
Udp test program: uftp which supports both unicast and multicast.  I only need unicast working. 

I had  two sites, sever and client  What i did was put following line policy on both wanos virtual appliances running on vmware workstaion. udp ,please see attached policy screenshot.

I tried to tranfer a ubuntu iso image and udp optimization did not work. 
Tomorrow, I will try txt file tomorrow.
My question:
1.   Is my setting correct or something missing ?
2.   What is the setup and best file type and size for simple udp  (unicast only) optimization working ?


General Discussion / compressing already compressed file
« on: March 04, 2015, 05:06:44 AM »
I just read a article about " compressing already compressed file could create a slightly bigger file".  Then, I am just wondering  that how  wanos deals with zipped file ( or already compressed file )  because sending zipped file is not uncommon in this days.


General Discussion / udp multicast igmp
« on: March 02, 2015, 02:14:06 AM »
Case 1:

We have developed application with udp, multicast and igmp.

Udp server sends a file snapshot every 0.3 second to clients because the content of the file changes constantly.  The file snapshot is complete file, not the difference.


Would  wanos appliance handle above case and give optimization ?

Case 2:
Based on case 1, we are currently (still under developing stage) trying to send compressed complete snapshot in order to save the bandwidth.

Would wanos appliance handle case 2 and give optimization ?



Simple bridge deployment of wanos does not require ip on each wanos appliance.


1) How does datastore on each site get built and synced for deduplication ?
2) How long is datastore time to live or gets refreshed for better tuning


As dynamic IP within a  period is fixed,   I can use google to find my two dynamic IPs ( two offices) and start networking such as ftp, ssh and etc.

But I do not know how to setup the wanos.

For example I have a ftp server on one side as follows,

office1_network --- switch --- wanos --- isp_router1 --- WAN --- isp_router2 ---wanos --- switch --- office2_network (including ftp_server, samba_server, and other servers, and each server with a dedicated computer)

Pls help.

It is actualan old question which was leave one wanos ( here was the core ) on inpath broke whole network.
looking for
client --- wanos(edge) --- route --- wanos(core) --- server

1. build network
client --- route --- server
everthing works : client can http ftp cifs server

2. put wanos (core) into network
client --- route --- wanos(core) --- server
nothing works: client can not http ftp cifs server

3. put wanos (edge) into network
everything works again.

As my understanding, step 2 should be working with no optimization. My test environment is vmware workstaion 10 with dedicate wan0 and lan0 interfaces. 
Or, I am missing something over here. Otherwise, in reality, there is no way you can put core and edge device up at the same time.

Troubleshooting / wanos throughput on kvm
« on: June 12, 2014, 06:13:11 AM »
First, I need to put wanos on VMware is very good.
After, I tried to put wanos(1.8) on kvm virtual machine by dd HDD image since KVM is only pure free open source virtual platform and with commands to manage VM.
But, the optimization did not work at all and even slower than no optimisation.  So,  I have to wonder if I do something wrong with the setup.  Please shed light on it.  Thanks.
