Re: [fun] [homegate] HOMENET working group proposal

[Keith Moore <[e-mail]>]

Anytime we develop standards, the standards apply to future products.  There's no point in defining standards for applications and devices that are already deployed.

Sure, it's nice to have backward compatibility.  But I don't think anyone is likely to propose standards for HOMENET that will significantly break compatibility with existing products.  It's not as if the set of applications and devices that one uses in a home network is disjoint from the set of applications and devices used in other networks.   And it's reasonable to expect that users of existing applications and devices might need to do some special-case configuration to get those applications and devices to continue to work.  

Just to pick one example, if a legacy device is v4-only, and the only access available is NATted v4 or native v6, there might be a need to configure the device to be externally accessible using a v6 address.  The home network might support v4 internally but there might not be v4 service available outside that enclave.

Backward compatibility = good.  Insisting that home networks always use the same kludges that are used now = bad.

Maybe the right answer is that the HOMENET group should consider what means are needed to provide some measure of compatibility with legacy devices and applications, that might continue to be used with networks meeting the new standards.  The working group seems like it's in a much better position than the IETF list to propose reasonable compromises on these issues.
