Abstract
A Path Computation Element (PCE) in a Multi-Protocol Label Switching (MPLS) network receives initial information of all Traffic Engineering (TE) links that is reported by a Label Switching Router (LSR), and stores the initial information into a TE database (TEDB). For the information of each TE link, the PCE determines initial values of pending bandwidth, reserved bandwidth and unreserved bandwidth of each TE-Class in the information of the TE link, and stores the initial values into the TEDB. The PCE receives a Constraint-based Routed Label Switched Path (CRLSP) calculation request from a Path Computation Client (PCC), calculates a Label Switched Path (LSP) according to the information of each TE link stored in the TEDB, and updates pending bandwidth, reserved bandwidth and unreserved bandwidth of TE-Class in the information of TE link corresponding to the LSP, wherein the information of TE link corresponding to the LSP is stored in the TEDB.
