Code Issues Proposed changes

Add Service Function Chain support(1) 

1. What is the problem
Tricircle does not support Service Function Chain

2. What is the solution to the problem

===============================
Service Function Chaining Guide
===============================
Service Function Chaining provides the ability to define an ordered list of
network services (e.g. firewalls, load balancers). These services are then
“stitched” together in the network to create a service chain.
Installation
^^^^^^^^^^^^
After installing tricircle, please refer to
https://docs.openstack.org/developer/networking-sfc/installation.html
to install networking-sfc.
Configuration
^^^^^^^^^^^^^
- 1 Configure central Neutron server
After installing the Tricircle and networing-sfc, enable the service plugins
in central Neutron server by adding them in ``neutron.conf.0``
(typically found in ``/etc/neutron/``)::
service_plugins=networking_sfc.services.flowclassifier.plugin.FlowClassifierPlugin,tricircle.network.central_sfc_plugin.TricircleSfcPlugin
In the same configuration file, specify the driver to use in the plugins. ::
[sfc]
drivers = tricircle_sfc
[flowclassifier]
drivers = tricircle_fc
- 2 Configure local Neutron
Please refer to https://docs.openstack.org/developer/networking-sfc/installation.html#Configuration
to config local networking-sfc.
How to play
^^^^^^^^^^^
- 1 Create pods via Tricircle Admin API
- 2 Create necessary resources in central Neutron server ::
neutron --os-region-name=CentralRegion net-create --provider:network_type vxlan net1
neutron --os-region-name=CentralRegion subnet-create net1 10.0.0.0/24
neutron --os-region-name=CentralRegion port-create net1 --name p1
neutron --os-region-name=CentralRegion port-create net1 --name p2
neutron --os-region-name=CentralRegion port-create net1 --name p3
neutron --os-region-name=CentralRegion port-create net1 --name p4
neutron --os-region-name=CentralRegion port-create net1 --name p5
neutron --os-region-name=CentralRegion port-create net1 --name p6
Please note that network type must be vxlan.
- 3 Get image ID and flavor ID which will be used in VM booting. In the following step,
the VM will boot from RegionOne and RegionTwo. ::
glance --os-region-name=RegionOne image-list
nova --os-region-name=RegionOne flavor-list
glance --os-region-name=RegionTwo image-list
nova --os-region-name=RegionTwo flavor-list
- 4 Boot virtual machines ::
openstack --os-region-name=RegionOne server create --flavor 1 --image $image1_id --nic port-id=$p1_id vm_src
openstack --os-region-name=RegionOne server create --flavor 1 --image $image1_id --nic port-id=$p2_id --nic port-id=$p3_id vm_sfc1
openstack --os-region-name=RegionTwo server create --flavor 1 --image $image2_id --nic port-id=$p4_id --nic port-id=$p5_id vm_sfc2
openstack --os-region-name=RegionTwo server create --flavor 1 --image $image2_id --nic port-id=$p6_id vm_dst
- 5 Create port pairs in central Neutron server ::
neutron --os-region-name=CentralRegion port-pair-create --ingress p2 --egress p3 pp1
neutron --os-region-name=CentralRegion port-pair-create --ingress p4 --egress p5 pp2
- 6 Create port pair groups in central Neutron server ::
neutron --os-region-name=CentralRegion port-pair-group-create --port-pair pp1 ppg1
neutron --os-region-name=CentralRegion port-pair-group-create --port-pair pp2 ppg2
- 7 Create flow classifier in central Neutron server ::
neutron --os-region-name=CentralRegion flow-classifier-create --source-ip-prefix 10.0.0.0/24 --logical-source-port p1 fc1
- 8 Create port chain in central Neutron server ::
neutron --os-region-name=CentralRegion port-chain-create --flow-classifier fc1 --port-pair-group ppg1 --port-pair-group ppg2 pc1
- 9 Show result in CentralRegion, RegionOne and RegionTwo ::
neutron --os-region-name=CentralRegion port-chain-list
neutron --os-region-name=RegionOne port-chain-list
neutron --os-region-name=RegionTwo port-chain-list
You will find a same port chain in each region.
- 10 Check if the port chain is working
In vm_dst, ping the p1's ip address, it should fail.
Enable vm_sfc1, vm_sfc2's forwarding function ::
sudo sh
echo 1 > /proc/sys/net/ipv4/ip_forward
Add the following route for vm_sfc1, vm_sfc2 ::
sudo ip route add $p6_ip_address dev eth1
In vm_dst, ping the p1's ip address, it should be successfully this time.
.. note:: Not all images will bring up the second NIC, so you can ssh into vm, use
"ifconfig -a" to check whether all NICs are up, and bring up all NICs if necessary.
In CirrOS you can type the following command to bring up one NIC. ::
sudo cirros-dhcpc up $nic_name

Support service function chaining creation and deletion based on networking-sfc,
currently all the ports in the port chain need to be in the same network and the
network type must be VxLAN.
