Moving Toward the Middle: The Case Against the End-to-End Argument in Home Networking Kenneth L. Calvert (University of Kentucky), and W. Keith Edwards and Rebecca E. Grinter (Georgia Institute of Technology)
Presenter: Kenneth L. Calvert

• Q: What fraction of the end-user problems can be solved with proposed approach?
• Grinter: We want to try empirically and see what are the results.

• John: Comment: If we impose star topology in home network, everything is getting much more simple.

• Q: Can we achieve similar goals with current protocols? Do we really need new standards?
• A: Yes, we need new programming interfaces, new election protocols, etc.

• Q: What business model will enable the proliferation of these devices?
• A: We don’t know. Time will show.

• are these subnets intentional or not?
• often they are, sometimes they are not.

• Q: In your survey, did a lot of people have multiple IP subnets? What about policies between them? Do you suggest making them transparent to the user?
• A: Often users had different subnets because of telecommuting. In such cases it is not a single trust domain; similarly there were multiple income homes, that wanted to keep things from interfering. It is certainly hard to make policy invisible to the user because that the policy by definition should be specified by the user.

• Q: Allison: Would your scheme break applications that require global visibility? For example Skype?
• A: It would not break anything that is not already broken. ALGs have the knowledge of these applications and make these applications play.
