Abstract Abstract
A Stateful Path Computation Element (PCE) maintains information on A Stateful Path Computation Element (PCE) maintains information on
the current network state, including: computed Label Switched Path the current network state, including: computed Label Switched Path
(LSPs), reserved resources within the network, and pending path (LSPs), reserved resources within the network, and pending path
computation requests. This information may then be considered when computation requests. This information may then be considered when
computing new traffic engineered LSPs, and for associated and computing new traffic engineered LSPs, and for associated and
dependent LSPs, received from Path Computation Clients (PCCs). The dependent LSPs, received from Path Computation Clients (PCCs). The
Path computation response from a PCE is helpful for the PCC to Path computation response from a PCE is helpful for the PCC to
