Security Considerations

We could use AAA to protect sensitive info or customized info, but choose to not, for simplicity.

Quality Assurance (test coverage, etc.)

Unit Tests coverage

• We are continuing to add more unit tests to improve the unit tests coverage (Gerrit Patch). These additions are not tracked by Sonar in the current release. We will add them in as soon as we can (i.e., as soon as after the Lithium build is blessed).

External tests have been conducted against the following operations:

• Access and manage maps using RESTCONF;
• Read network map and cost map using the ALTO RESTful API;
• Access and manage maps using ALTO Manager;
• Connect a mininet instance to ODL, run the pingall command, and read the corresponding maps from the ALTO RESTful API
