-============================
-Apexlake Installation Guide
-============================
-ApexLake is a framework that provides automatic execution of experiments and related data collection to enable
-a user validate infrastructure from the perspective of a Virtual Network Function (VNF).
-In the context of Yardstick, a virtual Traffic Classifier (vTC) network function is utilized.
-
-
-Framework Hardware Dependencies
-===============================
-In order to run the framework there are some hardware related dependencies for ApexLake.
-
-The framework needs to be installed on the same physical node where DPDK-pktgen_
-is installed.
-The installation requires the physical node hosting the packet generator must have 2 NICs
-which are DPDK_ compatible.
-
-The 2 NICs will be connected to the switch where the OpenStack VM network is managed.
-
-The switch used must support multicast traffic and IGMP snooping.
-Further details about the configuration are provided at the following here_.
-
-The corresponding ports to which the cables are connected need to be configured as VLAN trunks
-using two of the VLAN IDs available for Neutron.
-Note the VLAN IDs used as they will be required in later configuration steps.
-
-
-Framework Software Dependencies
-===============================
-Before starting the framework, a number of dependencies must first be installed.
-The following describes the set of instructions to be executed via the Linux shell in order to install
-and configure the required dependencies.
-
-1. Install Dependencies.
-
-To support the framework dependencies the following packages must be installed.
-The example provided is based on Ubuntu and needs to be executed in root mode.
-
-::
-
- apt-get install python-dev
- apt-get install python-pip
- apt-get install python-mock
- apt-get install tcpreplay
- apt-get install libpcap-dev
-
-2. Install the Framework on the Target System.
-
-After entering the Apexlake directory, run the following command.
-
-::
-
- python setup.py install
-
-3. Source OpenStack openrc file.
-
-::
-
- source openrc
-
-4. Create Two Networks based on VLANs in Neutron.
-
-To enable network communications between the packet generator and the compute node,
-two networks must be created via Neutron and mapped to the VLAN IDs
-that were previously used in the configuration of the physical switch.
-The following shows the typical set of commands required to configure Neutron correctly.
-
-::
-
- VLAN_1=2025
- VLAN_2=2021
- neutron net-create apexlake_inbound_network \
- --provider:network_type vlan \
- --provider:segmentation_id $VLAN_1 \
- --provider:physical_network physnet1
-
- neutron subnet-create apexlake_inbound_network \
- 192.168.0.0/24 --name apexlake_inbound_subnet
-
- neutron net-create apexlake_outbound_network \
- --provider:network_type vlan \
- --provider:physical_network physnet1
-
- neutron net-create apexlake_inbound_network \
- --provider:network_type vlan \
- --provider:segmentation_id $VLAN_2 \
- --provider:physical_network physnet1
-
- neutron subnet-create apexlake_outbound_network 192.168.1.0/24 \
- --name apexlake_outbound_subnet
-
-
-5. Configure the Test Cases
-
-The VLAN tags must also be included in the test case Yardstick yaml file
-as parameters for the following test cases:
- - TC 006
- - TC 007
- - TC 020
- - TC 021
-
-
-Install and Configure DPDK Pktgen
-+++++++++++++++++++++++++++++++++
-Execution of the framework is based on DPDK Pktgen.
-If DPDK Pktgen has not installed, it is necessary to download, install, compile and configure it.
-The user can create a directory and download the dpdk packet generator source code:
-
-::
-
- cd experimental_framework/libraries
- mkdir dpdk_pktgen
- git clone https://github.com/pktgen/Pktgen-DPDK.git
-
-For instructions on the installation and configuration of DPDK and DPDK Pktgen please follow the official
-DPDK Pktgen README file.
-Once the installation is completed, it is necessary to load the DPDK kernel driver, as follow:
-
-::
-
- insmod uio
- insmod DPDK_DIR/x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
-
-It is necessary to set the configuration file to support the desired Pktgen configuration.
-A description of the required configuration parameters and supporting examples is provided in the following:
-
-::
-
- [PacketGen]
- packet_generator = dpdk_pktgen
-
- # This is the directory where the packet generator is installed
- # (if the user previously installed dpdk-pktgen,
- # it is required to provide the director where it is installed).
- pktgen_directory = /home/user/software/dpdk_pktgen/dpdk/examples/pktgen/
-
- # This is the directory where DPDK is installed
- dpdk_directory = /home/user/apexlake/experimental_framework/libraries/Pktgen-DPDK/dpdk/
-
- # Name of the dpdk-pktgen program that starts the packet generator
- program_name = app/app/x86_64-native-linuxapp-gcc/pktgen
-
- # DPDK coremask (see DPDK-Pktgen readme)
- coremask = 1f
-
- # DPDK memory channels (see DPDK-Pktgen readme)
- memory_channels = 3
-
- # Name of the interface of the pktgen to be used to send traffic (vlan_sender)
- name_if_1 = p1p1
-
- # Name of the interface of the pktgen to be used to receive traffic (vlan_receiver)
- name_if_2 = p1p2
-
- # PCI bus address correspondent to if_1
- bus_slot_nic_1 = 01:00.0
-
- # PCI bus address correspondent to if_2
- bus_slot_nic_2 = 01:00.1
-
-
-To find the parameters related to names of the NICs and the addresses of the PCI buses
-the user may find it useful to run the DPDK tool nic_bind as follows:
-
-::
-
- DPDK_DIR/tools/dpdk_nic_bind.py --status
-
-Lists the NICs available on the system, and shows the available drivers and bus addresses for each interface.
-Please make sure to select NICs which are DPDK compatible.
-
-Installation and Configuration of smcroute
-++++++++++++++++++++++++++++++++++++++++++
-The user is required to install smcroute which is used by the framework to support multicast communications.
-The following is the list of commands required to download and install smroute.
-
-::
-
- cd ~
- git clone https://github.com/troglobit/smcroute.git
- cd smcroute
- sed -i 's/aclocal-1.11/aclocal/g' ./autogen.sh
- sed -i 's/automake-1.11/automake/g' ./autogen.sh
- ./autogen.sh
- ./configure
- make
- sudo make install
- cd ..
-
-It is also requires the creation a configuration file using the following command:
-
- SMCROUTE_NIC=(name of the nic)
-
-where name of the nic is the name used previously for the variable "name_if_2".
-For example:
-
-::
-
- SMCROUTE_NIC=p1p2
-
-Then create the smcroute configuration file /etc/smcroute.conf
-
-::
-
- echo mgroup from $SMCROUTE_NIC group 224.192.16.1 > /etc/smcroute.conf
-
-
-At the end of this procedure it will be necessary to perform the following actions to add the user to the sudoers:
-
-::
-
- adduser USERNAME sudo
- echo "user ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
-
-
-Experiment using SR-IOV Configuration on the Compute Node
-+++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-To enable SR-IOV interfaces on the physical NIC of the compute node, a compatible NIC is required.
-NIC configuration depends on model and vendor. After proper configuration to support SR-IOV,
-a proper configuration of OpenStack is required.
-For further information, please refer to the _SRIOV configuration guide
