RTE Link Bonding Ethernet Device Link Bonding for 1GbE and 10GbE ports to allow the aggregation of multiple (slave) NICs into a single logical interface. The bonded device processes these interfaces based on the mode of operation specified and supported. This implementation supports 4 modes of operation round robin, active backup balance and broadcast. Providing redundant links, fault tolerance and/or load balancing of network ports
Definition in file rte_eth_bond.h.
#define BONDING_MODE_ROUND_ROBIN (0) |
Round Robin (Mode 0). In this mode all transmitted packets will be balanced equally across all active slaves of the bonded 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 slave until such point as the primary slave is no longer available and then transmitted packets will be sent on the next available slaves. The primary slave can be defined by the user but defaults to the first active slave available if not specified.
Definition at line 32 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 slaves 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 39 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 slaves of the bonded.
Definition at line 45 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:
Definition at line 49 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 slave, according to the computed load. Statistics are collected in 100ms intervals and scheduled every 10ms
Definition at line 68 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 slave 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 slave MACs assigned and ARP reply send to that peer.

#define BALANCE_XMIT_POLICY_LAYER2 (0) |
Layer 2 (Ethernet MAC)
Definition at line 84 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 86 of file rte_eth_bond.h.
#define BALANCE_XMIT_POLICY_LAYER34 (2) |
Layer 3+4 (IP Addresses + UDP Ports) transmit load balancing
