From ebc75e892baa854d408ded92f3c9797cb75bb777 Mon Sep 17 00:00:00 2001 From: Praveen K V Date: Mon, 28 Mar 2016 12:29:52 +0530 Subject: [PATCH] Use 5-tuple to distribute flow setup across partitions The commit supports two scheme to distribute flow across partitions, - Flow-Handle based: Flow partition is chosen based on flow-handle allocated for flow in vrouter - Hash based: Flow partition is chosed based on 5-tuple in the flow. boost::hash_combine is used to compute hash-values Change-Id: I1636cca2b8112245acc67c9e48229d265d915547 Fixes-Bug: #1562508 --- src/vnsw/agent/pkt/flow_entry.cc | 5 +- src/vnsw/agent/pkt/flow_proto.cc | 118 +++++++++++++++--- src/vnsw/agent/pkt/flow_proto.h | 12 +- src/vnsw/agent/pkt/flow_table.cc | 24 +++- src/vnsw/agent/pkt/flow_table.h | 2 + src/vnsw/agent/pkt/pkt.sandesh | 23 ++++ src/vnsw/agent/pkt/pkt_sandesh_flow.cc | 20 +++ src/vnsw/agent/pkt/test/test_flow_eviction.cc | 101 ++++++++++++--- src/vnsw/agent/pkt/test/test_flow_util.h | 2 +- src/vnsw/agent/pkt/test/test_flowtable.cc | 16 ++- src/vnsw/agent/test/test_util.cc | 24 ++-- src/vnsw/agent/uve/test/test_port_bitmap.cc | 14 +-- .../agent/vrouter/ksync/flowtable_ksync.cc | 3 +- .../vrouter/ksync/ksync_flow_index_manager.cc | 3 + 14 files changed, 295 insertions(+), 72 deletions(-) diff --git a/src/vnsw/agent/pkt/flow_entry.cc b/src/vnsw/agent/pkt/flow_entry.cc index 46b47d0c1bc..0aae955d5ad 100644 --- a/src/vnsw/agent/pkt/flow_entry.cc +++ b/src/vnsw/agent/pkt/flow_entry.cc @@ -2071,6 +2071,10 @@ void FlowEntry::FillFlowInfo(FlowInfo &info) { info.set_allow(true); } + if (reverse_flow_entry_.get()) { + info.set_reverse_index(reverse_flow_entry_->flow_handle()); + } + if (is_flags_set(FlowEntry::NatFlow)) { info.set_nat(true); FlowEntry *nat_flow = reverse_flow_entry_.get(); @@ -2103,7 +2107,6 @@ void FlowEntry::FillFlowInfo(FlowInfo &info) { } info.set_nat_protocol(nat_flow->key().protocol); info.set_nat_vrf(data_.dest_vrf); - info.set_reverse_index(nat_flow->flow_handle()); info.set_nat_mirror_vrf(nat_flow->data().mirror_vrf); } } diff --git a/src/vnsw/agent/pkt/flow_proto.cc b/src/vnsw/agent/pkt/flow_proto.cc index 8283ac97f1d..78e0ac50e85 100644 --- a/src/vnsw/agent/pkt/flow_proto.cc +++ b/src/vnsw/agent/pkt/flow_proto.cc @@ -2,6 +2,7 @@ * Copyright (c) 2013 Juniper Networks, Inc.
