Abstract:
The Path Computation Element (PCE) working group (WG) has produced a
set of RFCs to standardize the behavior of the Path Computation
Element as a tool to help MPLS-TE and GMPLS LSP tunnels placement.
In the PCE architecture, a main assumption has been done concerning
the information that the PCE needs to perform its computation: the
Traffic Engineering Database (TED) contains all pertinent and
suitable information regarding the network that is in the scope of a
PCE. Nevertheless, the TED requirements as well as the TED
information have not yet been formalized. In addition, some recent
RFC (like the Backward Recursive Path Computation procedure) or WG
draft (like draft-ietf-pce-hierarchy ...) suffer from a lack of
information in the TED, leading to a non optimal result or to some
difficulties to deploy them. This memo tries to identity some TED
requirements for the PCE. It is split in two main section: the
identification of the specific information to be stored in the TED
and how it may be populated.
