Field Documentation

dpo_id_t* replicate_t_::rep_buckets

Vector of buckets containing the next DPOs, sized as repo_num.

Definition at line 77 of file replicate_dpo.h.

dpo_id_t replicate_t_::rep_buckets_inline[REP_NUM_INLINE_BUCKETS]

The rest of the cache line is used for buckets.

In the common case where there there are less than 4 buckets, then the buckets are on the same cachlie and we save ourselves a pointer dereferance in the data-path.

Definition at line 85 of file replicate_dpo.h.

u32 replicate_t_::rep_locks

The number of locks, which is approximately the number of users, of this load-balance.

Load-balance objects of via-entries are heavily shared by recursives, so the lock count is a u32.

Definition at line 72 of file replicate_dpo.h.

u16 replicate_t_::rep_n_buckets

number of buckets in the load-balance.

always a power of 2.

Definition at line 57 of file replicate_dpo.h.

dpo_proto_t replicate_t_::rep_proto

The protocol of packets that traverse this REP.

need in combination with the flow hash config to determine how to hash. u8.
