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.
