2.5.1.1. Different Security Governance Configuration Levels

The following one-to-one tests have been performed by executing an RTI Perftest C++98 Publisher and Subscriber between two nodes, connected to a switch via Ethernet. The communication has been restricted to a single interface and the transport has been set to UDPv4.

These tests are equivalent to the ones performed in the Core Libraries UDPv4 section (Unkeyed, UDPv4 10Gbps Network, C++98), but additionally enabling different Security Profiles (using different Governance configurations). The “Not using security libraries” values in the graphs below are equivalent to the Core Libraries numbers, so you can compare Connext performance with and without the Security Plugins.

Find information about the hardware, network, and command-line parameters after each of the tests.

The graph below shows the one-way latency without load between a Publisher and a Subscriber running in two Linux nodes in a 10Gbps network. The numbers have been taken using strict reliable reliability for all the different Security Profiles (described below).

Note

We use the median (50th percentile) instead of the average in order to get a more stable measurement that does not account for spurious outliers. We also calculate the average value and other percentile values, which can be seen in the Detailed Statistics section below.

Detailed Statistics

The following tables contain the raw numbers presented by RTI Perftest. These numbers are the exact output with no further processing.

Security Profiles

To test different levels of security, we have selected a well-known set of configurations. These configurations have been defined in the Governance files used by RTI Perftest. With these configurations, we have tested the minimum latency and maximum throughput achievable in different scenarios. The scenarios are described below.

The profiles we have used are the following:

  • Not using security libraries

In this scenario, RTI Security Plugins is not being used, therefore the performance is the same as what the Core Libraries provide in Unkeyed, UDPv4 10Gbps Network, C++98.

  • No protection

In this scenario, Security Plugins are enabled but no protection is provided at any level. This, as well as the previous scenario, is used as a way to calibrate the impact of using Security Plugins even when no security measures are applied.

The governance profile used in this scenario is the following:

<dds>
    <domain_access_rules>
      <domain_rule>
        <domains>
          <id_range>

  • RTPS ‘Sign’

This scenario sets the rtps_protection_kind to SIGN. This configuration provides protection against outsiders at the lowest cost.

      </domain_rule>
    </domain_access_rules>
</dds>
  • RTPS ‘Encrypt’

This scenario sets the rtps_protection_kind to ENCRYPT. This configuration is similar to the protection TLS provides.

The governance profile used in this scenario is the following:

<dds>
    <domain_access_rules>
      <domain_rule>

</dds>
  • RTPS ‘Sign with Original Authentication’ and Data ‘Encrypt’

This scenario sets the rtps_protection_kind to SIGN_WITH_ORIGIN_AUTHENTICATION. It also sets the data_protection_kind to ENCRYPT. This configuration is the common choice for intra-domain protection and confidentiality.

The governance profile used in this scenario is the following:

<dds>
    <domain_access_rules>
      <domain_rule>
        <domains>

  • RTPS ‘Sign,’ Submessage ‘Encrypt with Original Authentication,’ and Data ‘Encrypt’

This scenario sets the rtps_protection_kind to SIGN. It also sets the data_protection_kind to ENCRYPT and the metadata_protection_kind to ENCRYPT_WITH_ORIGIN_AUTHENTICATION. This configuration offers the most robust protection.

The governance profile used in this scenario is the following:

  • RTPS ‘Sign,’ Submessage ‘Encrypt’

This scenario sets the rtps_protection_kind to SIGN. It also sets the metadata_protection_kind to ENCRYPT. This configuration allows user data confidentiality (with insiders protection) while keeping Wireshark capabilities.

The governance profile used in this scenario is the following:
