From a3af337e06a79f7d1dacf42a319f241c907122fc Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Tue, 28 Mar 2017 03:49:52 -0700 Subject: MTRIE Optimisations 2 1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.
