From 097fa66b986f06281f603767d321ab13ab6c88c3 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Tue, 1 May 2018 05:17:55 -0700 Subject: fib: fib api updates Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns Signed-off-by: Ole Troan Signed-off-by: Paul Vinciguerra --- src/vnet/bier/bier.api | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) (limited to 'src/vnet/bier/bier.api') diff --git a/src/vnet/bier/bier.api b/src/vnet/bier/bier.api index b5ac8cabd39..0cc56cab50a 100644 --- a/src/vnet/bier/bier.api +++ b/src/vnet/bier/bier.api @@ -1,3 +1,4 @@ +/* Hey Emacs use -*- mode: C -*- */ /* * Copyright (c) 2016 Cisco and/or its affiliates. * Licensed under the Apache License, Version 2.0 (the "License"); @@ -18,7 +19,7 @@ This file defines vpp BIER control-plane API messages which are generally called through a shared memory interface. */ -option version = "1.1.0"; +option version = "1.2.0"; import "vnet/fib/fib_types.api"; /** \brief BIER Table Identifier @@ -77,16 +78,21 @@ define bier_table_details @param br_n_paths - The number of paths @param br_paths - The array of paths */ +typedef bier_route +{ + u32 br_bp; + vl_api_bier_table_id_t br_tbl_id; + u8 br_n_paths; + vl_api_fib_path_t br_paths[br_n_paths]; +}; + autoreply define bier_route_add_del { u32 client_index; u32 context; - u32 br_bp; u8 br_is_add; u8 br_is_replace; - vl_api_bier_table_id_t br_tbl_id; - u8 br_n_paths; - vl_api_fib_path_t br_paths[br_n_paths]; + vl_api_bier_route_t br_route; }; define bier_route_dump @@ -99,10 +105,7 @@ define bier_route_dump define bier_route_details { u32 context; - u16 br_bp; - vl_api_bier_table_id_t br_tbl_id; - u32 br_n_paths; - vl_api_fib_path_t br_paths[br_n_paths]; + vl_api_bier_route_t br_route; }; /** \brief BIER Imposition Add -- cgit 1.2.3-korg
