ISIS WG, I want to draw the attention of the WG to this new draft which we will also be presenting in Prague. The extensions described in draft-bowers-isis-te-attribute-set, together with those in draft-hegde-isis-advertising-te-protocols, address the same problem space as draft-ginsberg-isis-te-app. We think the approach described in these two drafts is both less disruptive and more flexible than the approach described in draft-ginsberg-isis-te-app. It is less disruptive because it only requires the introduction of new advertisements in network deployments that need this more complex functionality. The approach is also more flexible because routers simply advertise properties of links with extra scoping information (attribute-set and srlg-set ids). Applications are free to use this information as they see fit. Once the appropriate property scoping information is being advertised, introducing a new application does not require touching the routers to modify the property advertisements. With draft-ginsberg-isis-te-app, a router needs to explicitly advertise the applications that are expected to use a given link property. Adding a new application to the network requires that the routers be modified to explicitly advertise link properties as being usable by the new application. This approach seems cumbersome and restrictive.
