Q: Which is the usage/role of service layer within the compute request?

Context: PC-API

R: optional parameter. It is the possibility to identify the layer (technology) at which the tunnel is requested.

Italo/Sergio/Ricard:

serviceLayer is remained as inheritance from ONF

The TE Tunnel model allows to specify the topology-id, which can be used to infer the layer for the Tunnel if and only if the topology is at a single layer Need to further discuss with the TE Tunnel Design Team. PC-API will align with any change in the TE Tunnel

@rvilalta : Please comment serviceLayer

italobusi commented 7 years ago

The serviceLayer has been removed.

In TE Tunnel model I have found the following attributes:

       |  |  |  +--rw encoding?             identityref
       |  |  |  +--rw switching-type?       identityref

They are defined within the tunnel-p2p-params_config grouping which is not used by Path Computation RPC and it seems providing more attributes than needed by Path Computation RPC

To be further discussed with the TE Tunnel Design Team

It seems also dependent on issue #31

The issue is closed sicne the issue is covered in #31
