Field Documentation

ip46_address_t kp_pod_t::address

Destination address used to transfer traffic towards to that POD.

The address is also used pod ID and pseudo-random seed for the load-balancing process.

Definition at line 103 of file kp.h.

dpo_id_t kp_pod_t::dpo

The next DPO in the graph to follow.

Definition at line 144 of file kp.h.

fib_node_t kp_pod_t::fib_node

Registration to FIB event.

Definition at line 96 of file kp.h.

u8 kp_pod_t::flags

Some per-POD flags.

For now only KP_POD_FLAGS_USED is defined.

Definition at line 116 of file kp.h.

u32 kp_pod_t::last_used

Rotating timestamp of when KP_POD_FLAGS_USED flag was last set.

POD removal is based on garbage collection and reference counting. When an POD is removed, there is a race between configuration core and worker cores which may still add a reference while it should not be used. This timestamp is used to not remove the POD while a race condition may happen.

Definition at line 129 of file kp.h.

u32 kp_pod_t::next_hop_child_index

The child index on the FIB entry.

Definition at line 139 of file kp.h.

fib_node_index_t kp_pod_t::next_hop_fib_entry_index

The FIB entry index for the next-hop.

Definition at line 134 of file kp.h.

u32 kp_pod_t::vip_index

PODs are indexed by address and VIP Index.

Which means there will be duplicated if the same server address is used for multiple VIPs.
