Abstract:
The Path Computation Element (PCE) provides a solution for Traffic
Engineering (TE) based path calculation in large, multi-domain,
multi-region, or multi-layer networks. Depending on whether a PCE
keeps information about LSPs and reserved resource usage in the
network or not, it can be categorized as either stateful or
stateless.
This memo describes general considerations for stateful PCE(s) and
examines its applicability through a number of typical scenarios. It
shows how stateful PCE(s) can be applied to facilitate these
applications. PCEP extensions required for stateful PCE usage are
covered in separate document(s).
