Abstract:
A stateful Path Computation Element (PCE) has access to not only the
information disseminated by the network's Interior Gateway Protocol
(IGP), but also the set of active paths and their reserved resources
for its computation. The additional Label Switched Path (LSP) state
information allows the PCE to compute constrained paths while
considering individual LSPs and their interactions. This requires a
reliable state synchronization mechanism between the PCE and the
network, PCE and path computation clients (PCCs), and between
cooperating PCEs. The basic mechanism for state synchronization is
part of the stateful PCE specification. This draft presents
motivations for optimizations to the base state synchronization
procedure and specifies the required Path Computation Element
Communication Protocol (PCEP) extensions.
