* Several proposed changes to v1model standard_metadata for cheat sheet
Remove several fields that are deprecated in the v1model.p4 include file,
or will be soon:
+ drop
+ recirculate_port
+ clone_spec
+ lf_field_list
+ resubmit_flag
+ recirculate_flag
Add mention of more detailed documentation in behavioral-model
repository, for those that want to know more about how each field
behaves.
Group the fields by those that are only intended to be read in a P4
program, versues read/write, and which are only intended to be useful
in ingress, egress, or both.
* Minor updates to proposed v1model standard_metadata changes
* 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).
```

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.

correct functionality.

* 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.

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

* Adapt script to any machine
Adapt script to any machine, independent of the user. We support for installations in VM Ubuntu
* Clear user-bootstrap.sh
* Update user-bootstrap.sh
* Adapt installation script to any machine
* Update user-bootstrap to use latest version (#251)
* p4c tests are failing in latest version. So, let's skip it during vagrant provisioning

Add some hints to common issues users may run into
when following the README to run the tutorials.

P4Runtime uses a "complex" error message format to report errors for
batched Write & Read RPC requests. Some effort is required to parse the
error messages appropriately in order to print some useful debugging
information.
Running the exercises can race:
$ make run
mkdir -p build pcaps logs
p4c-bm2-ss --p4v 16 --p4runtime-file build/basic.p4info --p4runtime-format text -o build/basic.json basic.p4
sudo python ../../utils/run_exercise.py -t topology.json -b simple_switch_grpc
Reading topology file.
Building mininet topology.

s2: 1:h2 2:s1 3:s3

* Fixed location of pcaps and bmv2 logs
Also added reference to P4Runtime request logs to welcome message
* Fixed pcap/log location for Thrift/CLI-based switch class
* Repository reorganization for 2018 Spring P4 Developer Day.
* Port tutorial exercises to P4Runtime with static controller (#156)
* Switch VM to a minimal Ubuntu 16.04 desktop image
* Add commands to install Protobuf Python bindings to user_bootstrap.sh
* Implement P4Runtime static controller for use in exercises
From the exercise perspective, the main difference is that control plane
rules are now specified using JSON files instead of CLI commands. Such
JSON files define rules that use the same name for tables, keys, etc. as
in the P4Info file.
All P4Runtime requests generated as part of the make run process are
logged in the exercise's “logs” directory, making it easier for students
to see the actual P4Runtime messages sent to the switch.
Only the "basic" exercise has been ported to use P4Runtime.
The "p4runtime" exercise has been updated to work with P4Runtime
protocol changes.
Known issues:
- make run hangs in case of errors when running the P4Runtime controller
(probably due to gRPC stream channel threads not terminated properly)
- missing support for inserting table entries with default action
(can specify in P4 program as a workaround)
* Force install protobuf python module
* Fixing Ctrl-C hang by shutdown switches
* Moving gRPC error print to function for readability
Unforuntately, if this gets moved out of the file, the process hangs.
We'll need to figure out how why later.
* Renaming ShutdownAllSwitches -> ShutdownAllSwitchConnections
* Reverting counter index change
* Porting the ECN exercise to use P4 Runtime Static Controller
* updating the README in the ecn exercise to reflect the change in rule files
* Allow set table default action in P4Runtime static controller
* Fixed undefined match string when printing P4Runtime table entry
* Updated basic_tunnel exercise to use P4Runtime controller.
* Changed default action in the basic exercise's ipv4_lpm table to drop
* Porting the MRI exercise to use P4runtime with static controller
* Updating readme to reflect the change of controller for mri
* Update calc exercise for P4Runtime static controller
* Port source_routing to P4 Runtime static controller (#157)
* Port Load Balance to P4 Runtime Static Controller (#158)
* Added advanced Heavy Hitter Detection example
* Changed directory location
* Restored skeleton version
* Added files for common run infra with the other tutorials
* Updated readme
* Autogenerate setup rules
* Commends in simple_router.p4
* Fix typos
* Removed commended out lines
Starting with version 1.11, bmv2 conforms with the P4_16 spec and
push_front no longer marks new headers as valid. With this commit, we
add calls to setValid after calls to push_front. For people using older
bmv2 versions, this means that the new header will be marked valid twice
in a row, which should not be an issue.
Please let me know if I'm not supposed to edit this file directly. I have not used tocdoc before, but judging by the comments it seems ok to edit this way.
* Copying P4D2 Fall 2017 into P4D2 2018 East.
* Updated P4D2_2018_East VM. Added vagrant URL workaround, cdrom to VM. Updated to latest commits of BMV2, p4c, PI. Known issue with p4runtime exercise.
* Applied patch from @antoninbas in and updated solution
* Adding initial implementation of basic_encap example
* Updated basic_encap example to count the number of valid packets
* Updated basic_encap example to put encapsulation layer after Ethernet
header.
* Added solution file for basic_encap example
* Changed the name of the basic_encap example to basic_tunnel and called
the new header myTunnel. Also changed the myTunnel field names slightly.
* Updated the README file for the basic_tunnel exercise. Also added topo.pdf
image to serve as a reference during implementation.
* Updated basic/README.md to point to basic_tunnel as the next exercise.
* Updated the README for basic to point to basic_tunnel.
Updated the starter code for basic_tunnel to look like basic
solution with todo comments.
Updated send.py and receive.py to be able to send both plain IP
packets and tunneled IP packets.
Updated basic_tunnel.p4 to have same control flow as p4runtime
exercise.
* Updated the basic and basic_tunnel README files to remove references
to the old run.sh script.
Updated TODO list in basic_tunnel README
* Updated README files to indicate logs are in /tmp
* Updated README for basic_tunnel exercise to specify the etherType
field value.
Updating the P4Switch class to use different mechanism
for checking when the switch is listening on the Thrift
port. This might fix an issues where Mininet hangs on
start.
