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. In a
fist approach, the PCE embeds a Traffic Engineering Database (TED)
containing 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 PCE Hierarchy) or WG draft
(like draft-ietf-pce-stateful-pce ...) 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 identify some
Database, at large, requirements for the PCE. It is split in two
main sections: the identification of the specific information to be
stored in the PCE Database and how it may be populated.
