2. Demo slide 
3. Demo poster
4. Demo video

Requirements

• Ubuntu 18.04 with kernel version >= v4.14
• Python 2.7, python-pip, mininet, InfluxDB, Grafana

Provision emulator VM

Install p4tools

$ onos-setup-p4-dev 

Install BPFCollector

• Install pre-built bcc package from https://github.com/iovisor/bcc

• Clone BPFCollector repo. (See BPFCollector for details.)

  $ git clone https://gitlab.com/tunv_ebpf/BPFCollector.git $ cd BPFCollector $ git checkout -t origin/spec_1.0

• Enable JIT for eBPF to make BPFCollector run faster

  $ sudo sysctl net/core/bpf_jit_enable=1

• Install Cython to run the InfluxDB Client with better performance

  $ pip install Cython

• Add virtual interfaces for collector

  $ sudo ip link add veth_1 type veth peer name veth_2  $ sudo ip link set dev veth_1 up  $ sudo ip link set dev veth_2 up

Modify Mininet topology script

• Modify the file $ONOS_ROOT/tools/test/topos/bmv2-demo.py

  • Look for this line: 

    from mininet.link import TCLink

  • Change the line as follows:

    from mininet.link import TCLink, Intf

  • Look for this line: 

    net.build()

  • Below this line, add the followings:

    collectorIntf = Intf( 'veth_1', node=net.nameToNode[ "s12" ] )

How to run

• Run ONOS

  $ ONOS_APPS=drivers.bmv2,proxyarp,lldpprovider,hostprovider,fwd bazel run onos-local -- clean
