Hi Jon,

Please remind that aliases are meant to identify resources.  A single port number does not identify a resource; the combination of an ip address/fqdn and ports does.

If you want to include only an port number or a protocol, you can create an alias which will set the target-prefix to all prefixes of the domain.

I don't see the need to modify the current text. Thanks.

Cheers,
Med

Objet : [Dots] Are we being too restrictive in the Alias definition requirements?

Hi there,

Signal Draft 4.4.1.  Request Mitigation

   In the PUT request at least one of the attributes 'target-prefix',
   'target-fqdn', 'target-uri', or 'alias-name' MUST be present.

Data Draft 6.1.  Create Aliases

   In POST or PUT requests, at least one of the 'target-prefix',
   'target-fqdn', or 'target-uri' attributes MUST be present.  DOTS
   agents can safely ignore Vendor-Specific parameters they don't
   understand.

So, it is not possible to have an Alias template that contains just ports or protocols that can be used in a mitigation request that does include the 'target-prefix', 'target-fqdn', or 'target-uri' attributes.  Is this too restrictive?

Possible updates

Signal Draft 4.4.1.  Request Mitigation

NEW:
   In the PUT request at least one of the attributes 'target-prefix',
   'target-fqdn', 'target-uri', or 'alias-name' where the alias contains at least one of the attributes 'target-prefix', 'target-fqdn', 'target-uri', MUST be present.

Data Draft 6.1.  Create Aliases

NEW:
   In POST or PUT requests, at least one of the 'target-',
   attributes MUST be present.  DOTS
   agents can safely ignore Vendor-Specific parameters they don't
   understand.


Regards

Jon
