SIGCOMM 2019 Tutorial Edits (p4lang#272)
* Updated the utils/run_exercise.py to allow exercises to customize host configuration from the topology.json file. Now hosts and `ping` each other in the basic exercise. Other Linux utilities should work as well (e.g. iperf). ``` mininet> h1 ping h2 PING 10.0.2.2 (10.0.2.2) 56(84) bytes of data. 64 bytes from 10.0.2.2: icmp_seq=1 ttl=62 time=3.11 ms 64 bytes from 10.0.2.2: icmp_seq=2 ttl=62 time=2.34 ms 64 bytes from 10.0.2.2: icmp_seq=3 ttl=62 time=2.15 ms ^C --- 10.0.2.2 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 2.153/2.540/3.118/0.416 ms mininet> pingall *** Ping: testing ping reachability h1 -> h2 h3 h2 -> h1 h3 h3 -> h1 h2 *** Results: 0% dropped (6/6 received) ``` Only updated basic exercise, still need to update other exercises. Also, updated the root-bootstrap.sh because I was running into issues with latest version of vagrant. * Accidentially added the solution to the basic exercise in the previous commit. Undoing that here ... * Updated the topology.json file and table entries for the basic_tunnel exercise. * Updated P4Runtime exercise with new topology and table entries. * Fixed MAC addresses in P4Runtime exercise. It is working now. * Fixed MAC addresses in P4Runtime exercise starter code * Updated ECN exercise to use new topology.json file. Updated the table entries / MAC addresses as well. * Updated the topology.json file and table entries for the MRI exercise. * Updated source_routing exercise with new topology file and verified correct functionality. * Updated load_balance exercise with new topology. * Moved basic exercise triangle topology into a separate folder * Added new topology for the basic exercise: a single pod of a fat-tree. * Updated Makefiles and run_exercise.py to allow exercises to configure each switch with a different P4 program. This is mainly for the firewall exercise. * Updated Makefiles of project to work with new utils/Makefile * Updated load_balance and p4runtime exercise Makefiles * Initial commit of the firewall exercise, which is a simple stateful firewall that uses a bloom filter. Need to update README files * Initial commit of the path_monitor exercise. It is working but still need to update the README and figure out what we want the tutorial attendees to implement. * Updated README file in firewall exercise. Also removed the bits from the starter code that we want the tutorial attendees to implement * Renamed path_monitor exercise to link_monitor * Updated the README in the link_monitor exercise and removed the bits from the starter code that we want the tutorial attendees to implement. * Updated README for the firewall exercise * Adding pod-topo.png image to basic exercise * Added firewall-topo.png image to firewall exercise * Added link-monitor-topo.png to link_monitor exercise * Updated README files to point to topology images * Updated top-level README to point to new exercises. * Fixed link for VM dependencies script in README * Updated bmv2/pi/p4c commits * Updated README files for exercises to fix some typos and added a note about the V1Model architecture. * Added a note about food for thought in the link_monitor README * Updated the firewall.p4 program to use two register arrays rather than a single one. This is to make the design more portable to high line rate devices which can only support a single access to each register array. * Minor fix to firewall exercise to get rid of compiler warning. * Updated comment in firewall exercise. * Minor (typo) fixes in the firewall ReadMe * More info in firewall exercise ReadMe step 2 * Updated firewall.p4 to reuse direction variable * More testing steps, small fixes in firewall exercise Readme * Added food for thought to firewall Readme * Cosmetic fixes to firewall ReadMe * Made a few updates to the basic exercise README and added more details to the link_monitor exercise README. Also added a command to install grip when provisioning the VM. This could be useful for rendering the markdown README files offline. * Updated top level README so it can be merged into the master branch. * Moved cmd to install grip from root-bootstrap to user-bootstrap
