Why do we need separate and different copies of attributes for different applications? The SRLG tries to capture the risk relationships between multiple links. Those relationships don’t change depending on the application. Link attributes don’t require the variability that ASLA provides, and the overhead is high. How does this cost/benefit ratio make sense? > In any particular deployment case, a given attribute advertisement might be > used by one app, multiple apps, or all apps. > ASLA allows to unambiguously support all of these cases with a single > advertisement encoding format. > > The correct question to be resolving here is indeed the question which has > been discussed in an earlier thread: Is Generic Metric a link attribute which > can have application specific use cases?

If application A wants to use metric 16 and application B wants to use metric 122, that’s already doable. Why do we need a separate space per application???? Tony
