Sziasztok!

Mellekelve a kanadai egyetem P4 munkaja: slide-ok, ill. a demohoz 
szukseges installalas leirasa. Probaljatok ki, hogy egyaltalan lejon-e 
nektek minden, ill. nezzetek meg, hogy van-e belole hasznosithato 
szamotokra egy Spider backend-hez.

Istvan, Sanyi, majd esetleg beszeljuk meg, benneteket mennyire 
erdekelnek ezek az eredmenyek, illetve merrefele menjenek a kanadaiak.
Udv,

G.

Hi Gergely,

Here’s today presentation on P4.

The demo material is available on 
https://forge.ericsson.net/projects/DataPlaneResearch/ 
<https://forge.ericsson.net/projects/DataPlaneResearch/> --> Git --> spider.

I also made some changes to the demo instructions that Gordon provided 
(and I forget that I had this update, so Gordon you probably don’t need 
to go back and update the instructions file, everything should be there).

Action Item:

-The university to share their plans for the next few months ( ~ till 
the end of the year).

Regards,

/Bochra

Building
========
$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update
$ sudo apt-get install gcc-4.9
$ sudo apt-get install clang-3.5
$ sudo apt-get install cmake
$ sudo apt-get install realpath

$ wget http://www.tcpdump.org/release/libpcap-1.6.2.tar.gz 
$ tar -xzf libpcap-1.6.2.tar.gz
$ cd libpcap-1.6.2/
$ ./configure
$ make
$ make install
$ cd 
$ wget http://www.tcpdump.org/release/tcpdump-4.6.2.tar.gz
$ tar -xzf tcpdump-4.6.2.tar.gz
$ cd tcpdump-4.6.2/
$ ./configure
$ make
$ make install
$ cd 
$ wget https://www.openssl.org/source/old/1.0.1/openssl-1.0.1k.tar.gz
$ tar -xzf openssl-1.0.1k.tar.gz
$ cd openssl-1.0.1k/
$ ./config
$ make 
$ make install

First of all, clone the repository, and enter it:
    git clone --recurse-submodules --branch demo-06-26-2015 ssh://gitolite@forge.ericsson.net/dataplaneresearch/spider.git
    
To build the project, you may need to install a few things:

The p4 code has many dependencies, which take a long time to install. They can be installed as follows:
    
    # NB: Assumes that you're using Ubuntu 14.04
    cd spider/submodules/p4factory
    ./install.sh
    cd -

For the spider model, System C must be installed. This also takes a little bit of time:
    
    cd spider/build
    ./install-sysc.bash
    cd -
    
Additionally, you will need cmake, and either gcc>=4.9 or clang>=3.5. These can be installed using your package manager.

Once all the dependencies are installed, you can now set up the project to be built:

    # depending on which compiler you're using:
    CC=gcc-4.9 CXX=g++-4.9 cmake -G 'Unix Makefiles' ..
    make
    
Running
=======

If the project was built successfully, it should now be possible to run the demo.

Open two terminals (referred to as A and B) and navigate to spider/submodules/p4factory/targets/simple_router in both.

In terminal A, execute the following command, which starts the mininet topology with 6 hosts, each running the harpoon traffic generator script.

    ./run_demo.bash 6 --harpoon

In terminal B, execute the following command, which populates the soft switch's match-action tables and begins capturing on all of its interfaces.

    ./capture.bash 6
    
In terminal A, press enter, initiating the traffic generator scripts. After waiting for a few seconds for enough traffic to be captured, 
press ctrl-d to end the session. This will automatically stop the capture script, which will merge and copy the resulting pcap files into spider/build, 
to be used as input for the SystemC model.

Once this is done, navigate back to spider/build, and execute the following command to run the SystemC model:

    ./SpiderAPI
    
Once this command finishes, the output can be compared with the expected output by running the following command:

    ./compare.bash
