Questions About Implementing ara::com with SOME/IP

[ShehabAldeenMo]

Dear Engineer Langroodi,

For my graduation project, I’ll be focusing on implementing Adaptive AUTOSAR clusters, starting with ara::com. However, I need some clarification on the implementation details.

Referring to the image below and my current understanding:

I’m unsure whether I need to implement SOME/IP under the ara::com cluster or if it’s possible to leverage existing solutions like vsomeip. While I understand that vsomeip isn’t exactly SOME/IP, I’d appreciate your insights on the following questions:

Questions:-

1. Implementation or Reuse: Do I need to implement SOME/IP from scratch, or can I reuse an existing solution? If reusing is an option, where can I find the appropriate resources?

2. Starting Point in ara::com: From your perspective, which part of ara::com would be the best starting point for someone diving into this project?

---

Thank you in advance for your guidance!

Dear Shehab,

Implementation or Reuse: Do I need to implement SOME/IP from scratch, or can I reuse an existing solution? If reusing is an option, where can I find the appropriate resources?

It is not clear to me how you come to the conclusion that vsomeip is not exactly SOME/IP. As far as they (COVESA) claim, it is the implementation of SOME/IP. So, you can use it without any concern. To start with, please check their use guide and also their examples (specially the hello_word project).

Starting Point in ara::com: From your perspective, which part of ara::com would be the best starting point for someone diving into this project?

To be clear, ara::com it is not only SOME/IP, but it also can be DDS (as also mentioned in the image you've shared). On top of these communication protocols, we have the ara::com API. So, you can start with this document to understand the concept of Proxy/Skeleton Architecture and then learn more about the API itself.
At some point, you need to make the decision how many of these APIs (for instance, shall you have a service discovery or not) and how many of these communication protocols (only SOME/IP or SOME/IP + DDS) you want to cover in your project. If you want to cover the whole thing, maybe then it is more than a graduation project and the added value is also questionable.
