+============
 
-For new versions of the driver, patches for older kernels and the updated
-userspace tools, please follow the links at the end of this file.
+	The Linux bonding driver provides a method for aggregating
+multiple network interfaces into a single logical "bonded" interface.
+The behavior of the bonded interfaces depends upon the mode; generally
+speaking, modes provide either hot standby or load balancing services.
+Additionally, link integrity monitoring may be performed.

+3.1.1 Using DHCP with sysconfig
+-------------------------------
+
+	Under sysconfig, configuring a device with BOOTPROTO='dhcp'
+will cause it to query DHCP for its IP address information.  At this

+bonding instance to have an appropriately configured ifcfg-bondX file

-12.1.1 Bonding Mode Selection for single switch topology
---------------------------------------------------------
-
-	This configuration is the easiest to set up and to understand,
-although you will have to decide which bonding mode best suits your
-needs.  The tradeoffs for each mode are detailed below:
-
-balance-rr: This mode is the only mode that will permit a single
-	TCP/IP connection to stripe traffic across multiple
-	interfaces. It is therefore the only mode that will allow a
-	single TCP/IP stream to utilize more than one interface's
-	worth of throughput.  This comes at a cost, however: the
-	striping often results in peer systems receiving packets out
-	of order, causing TCP/IP's congestion control system to kick
-	in, often by retransmitting segments.
-
-	It is possible to adjust TCP/IP's congestion limits by
-	altering the net.ipv4.tcp_reordering sysctl parameter.  The
-	usual default value is 3, and the maximum useful value is 127.
-	For a four interface balance-rr bond, expect that a single
-	TCP/IP stream will utilize no more than approximately 2.3
-	interface's worth of throughput, even after adjusting
-	tcp_reordering.
-
-	If you are utilizing protocols other than TCP/IP, UDP for
-	example, and your application can tolerate out of order
-	delivery, then this mode can allow for single stream datagram
-	performance that scales near linearly as interfaces are added
-	to the bond.
-
-	This mode requires the switch to have the appropriate ports
-	configured for "etherchannel" or "trunking."
-
-active-backup: There is not much advantage in this network topology to
-	the active-backup mode, as the inactive backup devices are all
-	connected to the same peer as the primary.  In this case, a
-	load balancing mode (with link monitoring) will provide the
-	same level of network availability, but with increased
-	available bandwidth.  On the plus side, it does not require
-	any configuration of the switch.
-
-balance-xor: This mode will limit traffic such that packets destined
-	for specific peers will always be sent over the same
-	interface.  Since the destination is determined by the MAC
-	addresses involved, this may be desirable if you have a large
-	network with many hosts.  It is likely to be suboptimal if all
-	your traffic is passed through a single router, however.  As
-	with balance-rr, the switch ports need to be configured for
-	"etherchannel" or "trunking."
-
-broadcast: Like active-backup, there is not much advantage to this
-	mode in this type of network topology.
-
-802.3ad: This mode can be a good choice for this type of network
-	topology.  The 802.3ad mode is an IEEE standard, so all peers
-	that implement 802.3ad should interoperate well.  The 802.3ad
-	protocol includes automatic configuration of the aggregates,
-	so minimal manual configuration of the switch is needed
-	(typically only to designate that some set of devices is
-	usable for 802.3ad).  The 802.3ad standard also mandates that
-	frames be delivered in order (within certain limits), so in
-	general single connections will not see misordering of
-	packets.  The 802.3ad mode does have some drawbacks: the
-	standard mandates that all devices in the aggregate operate at
-	the same speed and duplex.  Also, as with all bonding load
-	balance modes other than balance-rr, no single connection will
-	be able to utilize more than a single interface's worth of
-	bandwidth.  Additionally, the linux bonding 802.3ad
-	implementation distributes traffic by peer (using an XOR of
-	MAC addresses), so in general all traffic to a particular
-	destination will use the same interface.  Finally, the 802.3ad
-	mode mandates the use of the MII monitor, therefore, the ARP
-	monitor is not available in this mode.
-
-balance-tlb: This mode is also a good choice for this type of
-	topology.  It has no special switch configuration
-	requirements, and balances outgoing traffic by peer, in a
-	vaguely intelligent manner (not a simple XOR as in balance-xor
-	or 802.3ad mode), so that unlucky MAC addresses will not all
-	"bunch up" on a single interface.  Interfaces may be of
-	differing speeds.  On the down side, in this mode all incoming
-	traffic arrives over a single interface, this mode requires
-	certain ethtool support in the network device driver of the
-	slave interfaces, and the ARP monitor is not available.
-
-balance-alb: This mode is everything that balance-tlb is, and more. It
-	has all of the features (and restrictions) of balance-tlb, and
-	will also balance incoming traffic from peers (as described in
-	the Bonding Module Options section, above).  The only extra
-	down side to this mode is that the network device driver must
-	support changing the hardware address while the device is
-	open.
-
-12.1.2 Link Monitoring for Single Switch Topology
--------------------------------------------------
-
-	The choice of link monitoring may largely depend upon which
-mode you choose to use.  The more advanced load balancing modes do not
-support the use of the ARP monitor, and are thus restricted to using

-as the ARP monitor).

+==============================================
 
-	You may encounter issues with the timing of link up and down
-reporting by the switch.
+13.1 Maximizing Throughput in a Single Switch Topology
+------------------------------------------------------
+
+	In a single switch configuration, the best method to maximize
+throughput depends upon the application and network environment.  The
+various load balancing modes each have strengths and weaknesses in
+different environments, as detailed below.
+
+	For this discussion, we will break down the topologies into
+two categories.  Depending upon the destination of most traffic, we
+categorize them into either "gatewayed" or "local" configurations.
+
+	In a gatewayed configuration, the "switch" is acting primarily
+as a router, and the majority of traffic passes through this router to
+other networks.  An example would be the following:
+
+
+     +----------+                     +----------+
+     |          |eth0            port1|          | to other networks
+     | Host A   +---------------------+ router   +------------------->
+     |          +---------------------+          | Hosts B and C are out
+     |          |eth1            port2|          | here somewhere
+     +----------+                     +----------+
+
+	The router may be a dedicated router device, or another host
+acting as a gateway.  For our discussion, the important point is that
+the majority of traffic from Host A will pass through the router to
+some other network before reaching its final destination.
+
+	In a gatewayed network configuration, although Host A may
+communicate with many other systems, all of its traffic will be sent
+and received via one other peer on the local network, the router.
+
+	Note that the case of two systems connected directly via
+multiple physical links is, for purposes of configuring bonding, the
+same as a gatewayed configuration.  In that case, it happens that all
+traffic is destined for the "gateway" itself, not some other network
+beyond the gateway.
+
+	In a local configuration, the "switch" is acting primarily as
+a switch, and the majority of traffic passes through this switch to
+reach other stations on the same network.  An example would be the
+following:
+
+    +----------+            +----------+       +--------+
+    |          |eth0   port1|          +-------+ Host B |
+    |  Host A  +------------+  switch  |port3  +--------+
+    |          +------------+          |                  +--------+
+    |          |eth1   port2|          +------------------+ Host C |
+    +----------+            +----------+port4             +--------+
+
+
+	Again, the switch may be a dedicated switch device, or another
+host acting as a gateway.  For our discussion, the important point is
+that the majority of traffic from Host A is destined for other hosts
+on the same local network (Hosts B and C in the above example).
+
+	In summary, in a gatewayed configuration, traffic to and from
+the bonded device will be to the same MAC level peer on the network
+(the gateway itself, i.e., the router), regardless of its final
+destination.  In a local configuration, traffic flows directly to and
+from the final destinations, thus, each destination (Host B, Host C)
+will be addressed directly by their individual MAC addresses.
+
+	This distinction between a gatewayed and a local network
+configuration is important because many of the load balancing modes
+available use the MAC addresses of the local network source and
+destination to make load balancing decisions.  The behavior of each
+mode is described below.
+
+
+13.1.1 MT Bonding Mode Selection for Single Switch Topology
+-----------------------------------------------------------
+
+	This configuration is the easiest to set up and to understand,
+although you will have to decide which bonding mode best suits your
+needs.  The trade offs for each mode are detailed below:
+
+balance-rr: This mode is the only mode that will permit a single
+	TCP/IP connection to stripe traffic across multiple
+	interfaces. It is therefore the only mode that will allow a
+	single TCP/IP stream to utilize more than one interface's
+	worth of throughput.  This comes at a cost, however: the
+	striping often results in peer systems receiving packets out
+	of order, causing TCP/IP's congestion control system to kick
+	in, often by retransmitting segments.
+
+	It is possible to adjust TCP/IP's congestion limits by
+	altering the net.ipv4.tcp_reordering sysctl parameter.  The
+	usual default value is 3, and the maximum useful value is 127.
+	For a four interface balance-rr bond, expect that a single
+	TCP/IP stream will utilize no more than approximately 2.3
+	interface's worth of throughput, even after adjusting
+	tcp_reordering.
+
+	Note that this out of order delivery occurs when both the
+	sending and receiving systems are utilizing a multiple
+	interface bond.  Consider a configuration in which a
+	balance-rr bond feeds into a single higher capacity network
+	channel (e.g., multiple 100Mb/sec ethernets feeding a single
+	gigabit ethernet via an etherchannel capable switch).  In this
+	configuration, traffic sent from the multiple 100Mb devices to
+	a destination connected to the gigabit device will not see
+	packets out of order.  However, traffic sent from the gigabit
+	device to the multiple 100Mb devices may or may not see
+	traffic out of order, depending upon the balance policy of the
+	switch.  Many switches do not support any modes that stripe
+	traffic (instead choosing a port based upon IP or MAC level
+	addresses); for those devices, traffic flowing from the
+	gigabit device to the many 100Mb devices will only utilize one
+	interface.
+
+	If you are utilizing protocols other than TCP/IP, UDP for
+	example, and your application can tolerate out of order
+	delivery, then this mode can allow for single stream datagram
+	performance that scales near linearly as interfaces are added
+	to the bond.
+
+	This mode requires the switch to have the appropriate ports
+	configured for "etherchannel" or "trunking."
+
+active-backup: There is not much advantage in this network topology to
+	the active-backup mode, as the inactive backup devices are all
+	connected to the same peer as the primary.  In this case, a
+	load balancing mode (with link monitoring) will provide the
+	same level of network availability, but with increased
+	available bandwidth.  On the plus side, active-backup mode
+	does not require any configuration of the switch, so it may
+	have value if the hardware available does not support any of
+	the load balance modes.
+
+balance-xor: This mode will limit traffic such that packets destined
+	for specific peers will always be sent over the same
+	interface.  Since the destination is determined by the MAC
+	addresses involved, this mode works best in a "local" network
+	configuration (as described above), with destinations all on
+	the same local network.  This mode is likely to be suboptimal
+	if all your traffic is passed through a single router (i.e., a
+	"gatewayed" network configuration, as described above).
+
+	As with balance-rr, the switch ports need to be configured for
+	"etherchannel" or "trunking."
+
+broadcast: Like active-backup, there is not much advantage to this
+	mode in this type of network topology.
+
+802.3ad: This mode can be a good choice for this type of network
+	topology.  The 802.3ad mode is an IEEE standard, so all peers
+	that implement 802.3ad should interoperate well.  The 802.3ad
+	protocol includes automatic configuration of the aggregates,
+	so minimal manual configuration of the switch is needed
+	(typically only to designate that some set of devices is
+	available for 802.3ad).  The 802.3ad standard also mandates
+	that frames be delivered in order (within certain limits), so
+	in general single connections will not see misordering of
+	packets.  The 802.3ad mode does have some drawbacks: the
+	standard mandates that all devices in the aggregate operate at
+	the same speed and duplex.  Also, as with all bonding load
+	balance modes other than balance-rr, no single connection will
+	be able to utilize more than a single interface's worth of
+	bandwidth.  
+
+	Additionally, the linux bonding 802.3ad implementation
+	distributes traffic by peer (using an XOR of MAC addresses),
+	so in a "gatewayed" configuration, all outgoing traffic will
+	generally use the same device.  Incoming traffic may also end
+	up on a single device, but that is dependent upon the
+	balancing policy of the peer's 8023.ad implementation.  In a
+	"local" configuration, traffic will be distributed across the
+	devices in the bond.
+
+	Finally, the 802.3ad mode mandates the use of the MII monitor,
+	therefore, the ARP monitor is not available in this mode.
+
+balance-tlb: The balance-tlb mode balances outgoing traffic by peer.
+	Since the balancing is done according to MAC address, in a
+	"gatewayed" configuration (as described above), this mode will
+	send all traffic across a single device.  However, in a
+	"local" network configuration, this mode balances multiple
+	local network peers across devices in a vaguely intelligent
+	manner (not a simple XOR as in balance-xor or 802.3ad mode),
+	so that mathematically unlucky MAC addresses (i.e., ones that
+	XOR to the same value) will not all "bunch up" on a single
+	interface.
+
+	Unlike 802.3ad, interfaces may be of differing speeds, and no
+	special switch configuration is required.  On the down side,
+	in this mode all incoming traffic arrives over a single
+	interface, this mode requires certain ethtool support in the
+	network device driver of the slave interfaces, and the ARP
+	monitor is not available.
+
+balance-alb: This mode is everything that balance-tlb is, and more.
+	It has all of the features (and restrictions) of balance-tlb,
+	and will also balance incoming traffic from local network
+	peers (as described in the Bonding Module Options section,
+	above).
+
+	The only additional down side to this mode is that the network
+	device driver must support changing the hardware address while
+	the device is open.
+

+----------------------------------------------------
+
+	The choice of link monitoring may largely depend upon which
+mode you choose to use.  The more advanced load balancing modes do not
+support the use of the ARP monitor, and are thus restricted to using
+the MII monitor (which does not provide as high a level of end to end
+assurance as the ARP monitor).
+
+13.2 Maximum Throughput in a Multiple Switch Topology
+-----------------------------------------------------
+
+	Multiple switches may be utilized to optimize for throughput
+when they are configured in parallel as part of an isolated network
+between two or more systems, for example:
+
+                       +-----------+
+                       |  Host A   | 
+                       +-+---+---+-+
+                         |   |   |
+                +--------+   |   +---------+
+                |            |             |
+         +------+---+  +-----+----+  +-----+----+
+         | Switch A |  | Switch B |  | Switch C |
+         +------+---+  +-----+----+  +-----+----+
+                |            |             |
+                +--------+   |   +---------+
+                         |   |   |
+                       +-+---+---+-+
+                       |  Host B   | 
+                       +-----------+
+
+	In this configuration, the switches are isolated from one
+another.  One reason to employ a topology such as this is for an
+isolated network with many hosts (a cluster configured for high
+performance, for example), using multiple smaller switches can be more
+cost effective than a single larger switch, e.g., on a network with 24
+hosts, three 24 port switches can be significantly less expensive than
+a single 72 port switch.
+
+	If access beyond the network is required, an individual host
+can be equipped with an additional network device connected to an
+external network; this host then additionally acts as a gateway.
+
+13.2.1 MT Bonding Mode Selection for Multiple Switch Topology
+-------------------------------------------------------------
+
+	In actual practice, the bonding mode typically employed in
+configurations of this type is balance-rr.  Historically, in this
+network configuration, the usual caveats about out of order packet
+delivery are mitigated by the use of network adapters that do not do
+any kind of packet coalescing (via the use of NAPI, or because the
+device itself does not generate interrupts until some number of
+packets has arrived).  When employed in this fashion, the balance-rr
+mode allows individual connections between two hosts to effectively
+utilize greater than one interface's bandwidth.
+
+13.2.2 MT Link Monitoring for Multiple Switch Topology
+------------------------------------------------------
+
+	Again, in actual practice, the MII monitor is most often used
+in this configuration, as performance is given preference over
+availability.  The ARP monitor will function in this topology, but its
+advantages over the MII monitor are mitigated by the volume of probes
+needed as the number of systems involved grows (remember that each
+host in the network is configured with bonding).
+
+14. Switch Behavior Issues
+==========================
+
+14.1 Link Establishment and Failover Delays
+-------------------------------------------
+

+timing of link up and down reporting by the switch.

 	In addition to the concerns about switch timings, if your
 switches take a long time to go into backup mode, it may be desirable
 to not activate a backup interface immediately after a link goes down.
 Failover may be delayed via the downdelay bonding module option.
 
-13. Hardware Specific Considerations
+14.2 Duplicated Incoming Packets
+--------------------------------
+
+	It is not uncommon to observe a short burst of duplicated
+traffic when the bonding device is first used, or after it has been
+idle for some period of time.  This is most easily observed by issuing
+a "ping" to some other host on the network, and noticing that the
+output from ping flags duplicates (typically one per slave).
+
+	For example, on a bond in active-backup mode with five slaves
+all connected to one switch, the output may appear as follows:
+
+# ping -n 10.0.4.2
+PING 10.0.4.2 (10.0.4.2) from 10.0.3.10 : 56(84) bytes of data.
+64 bytes from 10.0.4.2: icmp_seq=1 ttl=64 time=13.7 ms

+tables.  Initially, the switch does not associate the MAC address in
+the packet with a particular switch port, and so it may send the
+traffic to all ports until its MAC forwarding table is updated.  Since
+the interfaces attached to the bond may occupy multiple ports on a
+single switch, when the switch (temporarily) floods the traffic to all
+ports, the bond device receives multiple copies of the same packet
+(one per slave device).
+
+	The duplicated packet behavior is switch dependent, some
+switches exhibit this, and some do not.  On switches that display this
+behavior, it can be induced by clearing the MAC forwarding table (on
+most Cisco switches, the privileged command "clear mac address-table
+dynamic" will accomplish this).
