Which of the following is NOT a characteristic of Diameter protocol compared to RADIUS?

The reason that simpler implementation is identified as a characteristic that is NOT associated with the Diameter protocol compared to RADIUS lies in the inherent complexity and sophistication that Diameter entails.

Diameter was designed to address the limitations of RADIUS and provide additional functionalities, including better security mechanisms, support for more complex commands, and the ability to carry larger payloads. However, these enhancements come at the cost of complexity; Diameter employs a more intricate architecture, which includes the use of XML and protocol-specific extensions, making implementation more involved than that of RADIUS. RADIUS, while simpler and widely adopted, lacks many of the features that Diameter brings to the table.

In contrast, enhanced security features, less widespread adoption, and support for larger payloads are all characteristics that distinguish Diameter as a more advanced and capable protocol compared to RADIUS. Enhanced security, for instance, includes mechanisms like encrypted transport and integrity protection, which are significantly better than what RADIUS offers. The lower adoption rate reflects its newer status in the industry compared to the existing RADIUS installations. Lastly, Diameter supports larger payloads due to its ability to use binary encoding, which directly addresses the limitations faced by RADIUS.

By understanding these distinctions, it becomes clear why simpler implementation is not a
