# libvdeplug\_bonding(1)

multiplexing vdeplug module: bonding links

## NAME

libvdeplug\_bonding - multiplexing vdeplug module: bonding links

## SYNOPSIS

libvdeplug\_bonding.so

## DESCRIPTION

This is a libvdeplug multiplex module implementing the bonding of multiple links.

The common usage of this module is to support multiple links between virtual machines or switches. This module transmit packets on all the available links in a round-robin manner. If the links use several paths and channels it is possible to reach a higher bandwidth.

This module of libvdeplug4 can be used in any program supporting vde like **vde\_plug**, **kvm**, **qemu**, **user-mode-linux** and **virtualbox**.

The vde\_plug\_url syntax of this module is the following:

**bonding://\[*path*\]**\
 **bonding://\[*path*\]\[\[*OPTION*\]\[/*OPTION*\]\[/*OPTION*\]...\]**\

If *path* is omitted the path of the bonding is /tmp/vdenode\_$USERNAME (e.g. /tmp/vdenode\_john if the username is john).

## OPTIONS

- **mode=***MODE*

  *define the permissions for the bonding node (see chmod). MODE is an octal number.* *The standard permission mask is: 0600 (only processes owning to the same user can join the network).*

- **dirmode=***DIRMODE*

  *define the permissions for the bonding node control directory(see chmod). MODE is an octal number.* *If omitted, is computed from mode.*

- **grp=***GROUP*

  *define the group ownership of the bonding node.*

## EXAMPLES

**bonding:///tmp/bonding**\
 *Other virtual machines, namespaces or vde\_plug can join this bondinglink using* **vde:///tmp/hub** or simply **/tmp/hub**\
 Given two virtual machines using **bonding:///tmp/vm1** and **bonding:///tmp/vm2** respectively, it is possible to connect them using **vde\_plug /tmp/vm1 /tmp/vm2**. If the second virtual machine is running on a remote hosts; **ip1.vm2.domain.org** and **ip2.vm2.domain.org** are two ip addresses permitting to reach that remote host using different paths, the commands **vde\_plug /tmp/vm1 = ssh ip1.vm2.domain.org vde\_plug /tmp/vm2** and **vde\_plug /tmp/vm1 = ssh ip2.vm2.domain.org vde\_plug /tmp/vm2** create two channels between the two virtual machines. Packets are sent in turns on one or the other link.\
 **bonding:///tmp/bonding\[mode=0666\]**\
 It is the same bondinglink, but everybody is allowed to connect their processes.
