#define BONDING_MODE_ROUND_ROBIN (0)¶

Round Robin (Mode 0). In this mode all transmitted packets will be balanced equally across all active members of the bonding in a round robin fashion.

Definition at line 28 of file rte_eth_bond.h.

#define BONDING_MODE_ACTIVE_BACKUP (1)¶

Active Backup (Mode 1). In this mode all packets transmitted will be transmitted on the primary member until such point as the primary member is no longer available and then transmitted packets will be sent on the next available members. The primary member can be defined by the user but defaults to the first active member available if not specified.

Definition at line 33 of file rte_eth_bond.h.

#define BONDING_MODE_BALANCE (2)¶

Balance (Mode 2). In this mode all packets transmitted will be balanced across the available members using one of three available transmit policies - l2, l2+3 or l3+4. See BALANCE_XMIT_POLICY macros definitions for further details on transmit policies.

Definition at line 41 of file rte_eth_bond.h.

#define BONDING_MODE_BROADCAST (3)¶

Broadcast (Mode 3). In this mode all transmitted packets will be transmitted on all available active members of the bonding.

Definition at line 48 of file rte_eth_bond.h.

#define BONDING_MODE_8023AD (4)¶

802.3AD (Mode 4).

This mode provides auto negotiation/configuration of peers and well as link status changes monitoring using out of band LACP (link aggregation control protocol) messages. For further details of LACP specification see the IEEE 802.3ad/802.1AX standards. It is also described here https://www.kernel.org/doc/Documentation/networking/bonding.txt.

Important Usage Notes:

• for LACP mode to work the rx/tx burst functions must be invoked at least once every 100ms, otherwise the out-of-band LACP messages will not be handled with the expected latency and this may cause the link status to be incorrectly marked as down or failure to correctly negotiate with peers.
• For optimal performance during initial handshaking the array of mbufs provided to rx_burst should be at least 2 times the member count size.

Definition at line 53 of file rte_eth_bond.h.

#define BONDING_MODE_TLB (5)¶

Adaptive TLB (Mode 5) This mode provides an adaptive transmit load balancing. It dynamically changes the transmitting member, according to the computed load. Statistics are collected in 100ms intervals and scheduled every 10ms.

Definition at line 71 of file rte_eth_bond.h.

#define BONDING_MODE_ALB (6)¶

Adaptive Load Balancing (Mode 6) This mode includes adaptive TLB and receive load balancing (RLB). In RLB the bonding driver intercepts ARP replies send by local system and overwrites its source MAC address, so that different peers send data to the server on different member interfaces. When local system sends ARP request, it saves IP information from it. When ARP reply from that peer is received, its MAC is stored, one of member MACs assigned and ARP reply send to that peer.

Definition at line 77 of file rte_eth_bond.h.

#define BALANCE_XMIT_POLICY_LAYER2 (0)¶

Layer 2 (Ethernet MAC)

Definition at line 88 of file rte_eth_bond.h.

#define BALANCE_XMIT_POLICY_LAYER23 (1)¶

Layer 2+3 (Ethernet MAC + IP Addresses) transmit load balancing

Definition at line 90 of file rte_eth_bond.h.

#define BALANCE_XMIT_POLICY_LAYER34 (2)¶

Layer 3+4 (IP Addresses + UDP Ports) transmit load balancing

Definition at line 92 of file rte_eth_bond.h.
