4.4.2 Stateful PCE
The main function introduced by stateful PCE over the base PCE implementation is
the ability to synchronize the LSP state between the PCC and the PCE. This allows
the PCE to have all the required LSP information to perform reoptimization and
updating of the LSP paths.
Table 33 describes the TLVs, objects, and messages supported by stateful PCE on
the 7705 SAR.
