No module sswitch_runtime

[caopeirui]

Hi @edgar-costa :

p4utils/utils/sswitch_thrift_API.py has the import code: from sswitch_runtime import SimpleSwitch from sswitch_runtime.ttypes import * However, 'sswitch_runtime' cannot be found. Where is the sswitch_runtime module?

By the way, would you mind telling me the most significant difference between SimpleSwitchThriftAPI and SimpleSwitchP4RuntimeAPI ?

Hi @caopeirui, the module sswitch_runtime is included in the behavioral model. You can check out the requirements for P4-Utils here. The difference between the SimpleSwitchThriftAPI and the SimpleSwitchP4RuntimeAPI is that the former is the legacy control plane API of the behavioral model, the latter is a new one based on P4Runtime that aims at becoming the new standard for the control plane of all the P4 devices. Unfortunately, SimpleSwitchP4RuntimeAPI does not support registers operations yet, so you may still want to use the legacy API.

maybe you can find it in the file "behavioral-model/targets/simple_switch/thrift/simple_switch.thrift"
