A

• Address

It refers to the IP address of either the source or destination machine.

B

• Bridge Mode

Bridge mode is the default Wanos deployment setting. In this mode two interfaces are used to place the Wan Optimizer in the traffic flow path. The lan0 interface connects to the LAN workstations or server network and the wan0 interface connects to the WAN Router or Firewall. Traffic that flows through the appliance that should not be optimized can be bypassed. Optimization starts when a peer is detected. Optimization stops and enables pass-through when the peer times out.

C

• Change SSH & Web Password

Changes the Wanos Web GUI and SSH passwords.

• Compression Level

Level 3 for best results. Level 0 to disable. Higher Compression levels will generally provider better compression ratio at the cost of extra CPU cycles. Lower Compression levels will provider lower ratios, but provide higher throughput. Packet Loss Recovery (PLR) option is compatible with Level 2 and Level 3 options only.

• Core (Deprecated)

A term used to refer to a Head Office or central site

• CPU Threads

The capability to run processes simultaneously. This feature is hardware-dependent and Wanos can support up to 8 cores/threads.

D

• Datastore

Datastore Partition. The datastore stores the byte-cache data. When the datastore is full it reaches 100% efficiency and starts managing the byte-cache in a first in first out (FIFO) queue. Hence new data replaces old data and the datastore remains at 100%.

• Datastore Disk

The drive that the datastore is store on. It is essential to check that sufficient disk space is available for the deployment. The datastore maximum size grows with each configured peer.

• Date

Allows you to manually set the date in mm/dd/yy (month/day/year) format.

• Deduplication Level (Is a specialized data compression technique for eliminating duplicate copies of repeating data.)

This option is for high speed or resource limited scenarios. Level 4 provides the highest compression ratio and utilizes the most CPU resources. Level 1 provides the highest throughput of deduplicated traffic (Send/Receive) with low compression ratio and less CPU resources. Level 0 receives deduplicated traffic but does not send it and utilizes the least CPU resources.

• Deployment Mode

1. Bridge Mode is a transparent, inline, bump in the wire deployment using two interfaces. Requires little to no configuration. This is the default option.
   
2. Router mode uses only the wan0 interface, but uses two IP address for inside and outside routing. Requires routing configuration on WAN and LAN.
   
3. Tunnel mode encapsulates optimized traffic in an UDP header and tunnels the traffic to the remote end. MultiSite Peer IP configuration is required in order for Tunnel Mode to work.

• DNS Server

Optional DNS Server. A technology used to translate domain names into IP addresses. Users can specify their preferred DNS servers in the Wanos web GUI.

E

• Edge (Deprecated)

A term used to refer to a Branch or remote site

• Export

A feature that allows you to extract data. At the moment, the only option available in this field is PDF.

• Encapsulation

For optimized traffic, Encapsulation needs to match on all sites. IPComp is the most efficient, but may not be compatible with intermediate NAT devices. UDP is more lenient to NAT and Firewall devices but carry extra overhead per packet.

G

• Global Wan Tx Rate

The Global WAN Outbound Tx Shaper. Values are in kbps. Default is 0. 0 means Disabled. The Global Shaper will limit all outbound traffic to the target rate. This is useful in scenarios where peak WAN speeds have a cost implication. The Global rate is also used where congestion in the WAN affect Packet Loss Recovery. In these scenarios it is recommended to set the WAN speed.

H

• Hostname

A name given to the Wanos appliance to identify it on the network. There is a 30-character limit and special characters are not allowed. wanos is the default value.

I

• Interface Graphs

A graph representation of data going in and out of network interfaces.

L

• LAN - Local Area Network

A computer network that spans in a small area.

• Local Status

A term used to indicate the state of the local WAN optimizer. It could be either "Ready" or "Loading". Ready means deduplication is ready to start processing traffic. Loading means it is building/starting the database.

N

• Netflow Collector IP

Enable external netflow collector. Default value is disable.

• Netflow Collector Port

Optional external netflow collector.

• Netflow Exports

External netflow collector port. Default value is 2055.

O

• Optimization Level

An option in Wanos web GUI that allows users to configure the level of WAN Optimization. Setting it to High means Wanos will provide maximum WAN optimization possible at the cost of high utilization of hardware. Setting it to Low means Wanos will prioritize throughput speed over reduction ratios.

P

• Packet Loss Recovery

Level 1 - Most conservative loss detection and recovery. Level 4 - Most aggressive loss detection and recovery. Conservative PLR means Wanos will wait longer and generate less PLR traffic. Aggressive Loss detection means Wanos will try to recover from loss earlier. TCP Acceleration would typically be higher on more aggressive settings.

• Peer

A machine capable of receiving and sending data or sharing resources and services on a network.

• Peer Status

It shows the statuses of different Peers connected to the Wanos appliance. Valid values are "Down" and "Up".

• Peer Timeout (value in seconds)

Controls how long to wait before considering a peer down. Traffic for this peer will switch to bypass until the next peer hello packet is received. Ready peers move to up state instantly as soon as the first tagged TCP SYN packet is received. A peer timeout of 10 seconds will cause Wanos to move to the bypass state sooner. A peer timeout of 120 seconds will ensure Wanos waits 2 minutes before considering the peer to be down and move the traffic to pass-through.

• Period

The capability to capture data by setting a specific time frame by the hour, day, month or year.

• PLR

Short for Packet Loss Recovery. Valid values are "On" and "Off".

• Port

An endpoint in which a network data passes through using a specific protocol like TCP/IP. Users can set default or custom port numbers accordingly.

• Promiscuous Mode

A mode used by Virtualization products that allows the physical wired NICs to pass all network traffic to the target virtual machine instead of filtering the packets intended only for it.

• Protocol

Method used on how data is transferred through a network.

R

• Reboot Appliance

Reboot the Wanos Appliance. It allows the user to reboot the Wanos appliance without logging directly into it.

• Reduction

The percentage of reduction of data transfers due to Wanos Optimization.

• Reset Configuration

Reset configurations to factory defaults. Similar to running /etc/wanos/clean.sh

• Reset Datastore

Clear the Local Deduplication Datastore for all Peers. Requires Datastore Clear on Remote Peers.

• Reset Service

Reset the Wanos Service.

• Reset Statistics

Reset Log and Statistics. This option will delete all the existing logs and statistics captured by the Wanos appliance.

S

• Secondary Address / Mask

This option is only available in Router mode. It requires a secondary IP address (inside). Format IP/Mask x.x.x.x/x When enabled, internal traffic to be optimized should be routed to this gateway address.

• Shutdown Appliance

Turns off the Wanos appliance through the Wanos web GUI. Similar to issuing a sudo poweroff command in the terminal if the user is logged in directly inside the Wanos appliance.

• Software Version

Shows the current version of the appliance.

• SSH

Provides remote access via SSH. This feature is enabled by default.

• Switch Interface Port Roles

This is an option that switches wan0 and lan0 switches as if you were physically swapping the LAN cables. Use this option if "Peer detected on lan0" is detected in the logs.

• System Memory

Amount of RAM available for Wanos. In Wanos 32-bit, it can support up to 4 GB but usable memory may vary from one hardware to another.

T

• Time

Allows you to manually set the time in hh/mm/yy (hours/months/years) format.

• Total GB Saved

The amount of data saved from being re-transmitted through the network due to Wanos Optimizations.

U

• Uptime

Indicates how long the appliance is running.

W

• WAN - Wide Area Network

A computer network that spans in a large area. It consists of interconnected LANs.

• WAN Gateway

Gateway on wan0 device. Default value is 192.168.1.1

• WAN IP Address / Mask

wan0 IP Address. Format IP/Mask x.x.x.x/x Default value is 192.168.1.201/24
