| 17 | // The implementation of the open flow agent (ofagent) uses a GRPC connection |
| 18 | // to VOLTHA accross several implementaton packages including the ofagent and |
| 19 | // openflow packages. This GRPC connection is shared through packages and type |
| 20 | // instances via injection. |
| 21 | // |
| 22 | // As the ofagent executes within a micro-service environment it is |
| 23 | // possible that the GRPC connection is reset (re-established). When the connection |
| 24 | // is re-established, because injection is used, the new value needs to be |
| 25 | // re-injected across the implementation. |
| 26 | // |
| 27 | // To help simply the re-injection or value change scenario a holder for the |
| 28 | // GRPC connection is established so that the reference to the holder can |
| 29 | // stay [sic] consistant over the lifetime of the ofagent while the underlying |
| 30 | // GRPC connection can change without walking the entire runtime structure. |
