Which application uses which metric type is defined by the application. For example in flex-algo FAD defines which metric-type its going to use. In SR-TE, the constraint list specifies which metric-type it is going to use.

Be cautious of content] Hey Gunter, > It doesn't make sense to have Application specific values if a particular > metric is obtained only dynamically, It sure does. Please notice what ASLA RFCs say up front in the abstract. ASLA is useful for: A) application- specific values for a given attribute AND B) indication of which applications are using the advertised value for a given link. It does not matter if the value is same or different ... what matters is automated and consistent indication which of my applications given new metric applies to. I already mentioned this to Ron here: https://mailarchive.ietf.org/arch/msg/lsr/OgGLI8yezUDWU-EZePoIj6y6ENk/<https://urldefense.com/v3/__https:/mailarchive.ietf.org/arch/msg/lsr/OgGLI8yezUDWU-EZePoIj6y6ENk/__;!!NEt6yMaO-gk!Tny8sU7cmjqLAbDVnliN7lck7J4tCBAHr10i3CW2G9oviUWo8b2RTJxCXc0gvWOz$> Can anyone explain how do I map generic metric to selected network applications I am to run in the network ? Thx, Robert. On Fri, Jul 30, 2021 at 11:05 AM Van De Velde, Gunter (Nokia - BE/Antwerp) <[email protected]<mailto:[email protected]>> wrote: A little late in the discussion... (PTO events do happen) a quick opinion on the below discussion on whether Generic metric sub-tlv should be encoded on a ASLA or not. For me, it depends on how the metric for the corresponding metric-type is obtained and if it can be configured (static). It doesn't make sense to have Application specific values if a particular metric is obtained only dynamically, for eg, dynamically measured delay is going to be same for all applications. On the contrary, te-metric can be configured, and we can in principle configure different values for different applications. My opinion is that if any of the metric-types in the Generic metric sub-tlv can be configured, it should be inside the ASLA. G/
