From 2cbda68cf08d9319cf88a1b221b9c7e55a09d124 Mon Sep 17 00:00:00 2001 From: Dino Madarang Date: Tue, 3 Oct 2017 01:02:17 +0000 Subject: samples: Add generic L3 forwarder tests A generic throughput test case that can be used as a stub code for a Linux-based VNF configured as an L3 forwarder. Supported context: * Standalone OVSDPDK and SRIOV * Baremetal Code changes: * Allow pmd-cpu-mask and lcore mask for OVS DPDK * router_vnf.py - configures interface IP addresses and static arp entries using ip command * NFVi KPIs * Allow cputune tag for standalone context to be able to PIN on NUMA 1 cpus SRIOV Test cases: * RFC2544 Ethernet framesizes, 128K Flows * 2,4 and 6 ports * 2 and 3 vcpus per port * OVSDPDK Test cases: * RFC2544 Ethernet framesizes, 128K Flows * 2 and 4 ports * 2 vcpus per port * 2 PMD threads per port TODO: * Documentation * Add 6 ports tests References: * router_vnf.py is based on sample_vnf.py * tc_*.yaml files are based on acl/vfw test case files Added unitests Added get_stats to parse ip -s link Change-Id: Id1b969d5420dfcab7c1e695acbd2cd1655747efe Signed-off-by: Dino Simeon Madarang Signed-off-by: Kavindya Deegala Reviewed-by: Alain Jebara Reviewed-by: Deepak S Reviewed-by: Emma Foley Reviewed-by: Rodolfo Alonso Hernandez Reviewed-by: Ross Brattain Reviewed-by: Edward MacGillivray Signed-off-by: Dhaval Patel Signed-off-by: Ross Brattain (cherry picked from commit 9bf492e01dad7309287e8491ec7ac29f43032aed) --- .../vnf_generic/vnf/test_router_vnf.py | 267 +++++++++++++++++++++ 1 file changed, 267 insertions(+) create mode 100644 tests/unit/network_services/vnf_generic/vnf/test_router_vnf.py (limited to 'tests') diff --git a/tests/unit/network_services/vnf_generic/vnf/test_router_vnf.py b/tests/unit/network_services/vnf_generic/vnf/test_router_vnf.py new file mode 100644 index 000000000..9ed6fd5b3 --- /dev/null +++ b/tests/unit/network_services/vnf_generic/vnf/test_router_vnf.py @@ -0,0 +1,267 @@ +#!/usr/bin/env python + +# Copyright (c) 2016-2017 Intel Corporation +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. +# + +from __future__ import absolute_import + +import unittest +import mock + +from tests.unit import STL_MOCKS +from tests.unit.network_services.vnf_generic.vnf.test_base import mock_ssh + + +STLClient = mock.MagicMock() +stl_patch = mock.patch.dict("sys.modules", STL_MOCKS) +stl_patch.start() + +if stl_patch: + from yardstick.network_services.vnf_generic.vnf.router_vnf import RouterVNF + + +TEST_FILE_YAML = 'nsb_test_case.yaml' +SSH_HELPER = 'yardstick.network_services.vnf_generic.vnf.sample_vnf.VnfSshHelper' + + +name = 'vnf__1' + + +class TestRouterVNF(unittest.TestCase): + VNFD = {'vnfd:vnfd-catalog': + {'vnfd': + [{'short-name': 'RouterVNF', + 'vdu': + [{'routing_table': [], + 'description': 'RouterVNF', + 'name': 'router-baremetal', + 'nd_route_tbl': [], + 'id': 'router-baremetal', + 'external-interface': + [{'virtual-interface': + {'dst_mac': '00:00:00:00:00:04', + 'vpci': '0000:05:00.0', + 'local_ip': '152.16.100.19', + 'type': 'PCI-PASSTHROUGH', + 'netmask': '255.255.255.0', + 'dpdk_port_num': 0, + 'bandwidth': '10 Gbps', + 'driver': "i40e", + 'dst_ip': '152.16.100.20', + 'local_iface_name': 'xe0', + 'local_mac': '00:00:00:00:00:02'}, + 'vnfd-connection-point-ref': 'xe0', + 'name': 'xe0'}, + {'virtual-interface': + {'dst_mac': '00:00:00:00:00:03', + 'vpci': '0000:05:00.1', + 'local_ip': '152.16.40.19', + 'type': 'PCI-PASSTHROUGH', + 'driver': "i40e", + 'netmask': '255.255.255.0', + 'dpdk_port_num': 1, + 'bandwidth': '10 Gbps', + 'dst_ip': '152.16.40.20', + 'local_iface_name': 'xe1', + 'local_mac': '00:00:00:00:00:01'}, + 'vnfd-connection-point-ref': 'xe1', + 'name': 'xe1'}]}], + 'description': 'RouterVNF', + 'mgmt-interface': + {'vdu-id': 'router-baremetal', + 'host': '1.2.1.1', + 'password': 'r00t', + 'user': 'root', + 'ip': '1.2.1.1'}, + 'benchmark': + {'kpi': ['packets_in', 'packets_fwd', 'packets_dropped']}, + 'connection-point': [{'type': 'VPORT', 'name': 'xe0'}, + {'type': 'VPORT', 'name': 'xe1'}], + 'id': 'RouterVNF', 'name': 'VPEVnfSsh'}]}} + + scenario_cfg = {'nodes': {'cpt__0': 'compute_0.compute_nodes', + 'tg__0': 'trafficgen_1.baremetal', + 'vnf__0': 'vnf.yardstick'}, + 'options': {'flow': {'count': 128000, + 'dst_ip': ['10.0.3.26-10.0.3.105'], + 'dst_port': ['2001-2004'], + 'src_ip': ['10.0.2.26-10.0.2.105'], + 'src_port': ['1234-1238']}, + 'framesize': {'downlink': {'1024B': 100}, + 'uplink': {'1024B': 100}}, + 'rfc2544': {'allowed_drop_rate': '0.0001 -
