Hi Mike and Shuping,




As the co-author of draft-liu-apn-edge-usecase-00,  I am also interested in the data discovery, and have some questions:




(1) It is easy to understand the process of discovering the device, and the process of computing after the data being generated, collected and forwarded. So what dose the data discovery means?




(2) From draft-mcbride-edge-data-discovery-overview, I can think of the potential combination of APN and data discovery may be that different types of data require different SLA guaranteed networks, such as general collected data, control data, and widely used video data. I wonder if this understanding is the "application data needs", or do you think there is a deeper combination?




We can have more discussion on them.




Thanks,

Peng

Hi Mike,  

  

It sounds an interesting use case to make the network aware of the applications data needs.  

  

Just to clarify first, what would be the “applications data needs” to be more specific? Any idea on how to express/formulate these data needs and integrate with APN? 

  

Best regards,   

Shuping

Hi Shuping, 

  

> Some use cases in Edge Computing have been listed in the draft:  https://tools.ietf.org/html/draft-liu-apn-edge-usecase-00 

  

One of the findings, of a series of edge computing side meetings, was the need for standardized edge data discovery: 

  

https://datatracker.ietf.org/doc/draft-mcbride-edge-data-discovery-overview/ 

  

Perhaps we can include an APN use case (or separate draft) where the network is aware of the applications data needs, is able to find the data and then compute on it. Something worth investigating  anyway.  

  

Thanks, 

mike

 Subject: [Apn] APN Use Cases   

  

Dear all, 

  

We have been exploring the use cases that could benefit from APN.  

  

Some use cases in Edge Computing have been listed in the draft:  https://tools.ietf.org/html/draft-liu-apn-edge-usecase-00 

Some use cases in Game Acceleration have been listed in the draft:  https://tools.ietf.org/html/draft-zhang-apn-acceleration-usecase-00 

  

What do you think about these use cases? What are the benefits that can be brought by APN? Would you like to share some other use cases that are valuable to you?  

  

Thank you! 

  

Best regards,  

Shuping
