- In this paper, we present the design and the implementation of OSPF-TE routing information collector for MPLS and GMPLS networks. OSPF is commonly used as an IGP in MPLS and GMPLS networks to determine the topology over which LSPs can be established. TE extensions have been recently enabled in OSPF to support SPF tree calculation upon different purposes, thus possibly achieving optimal path computation and helping improve resource utilization efficiency. The IETF has standardized the PCE-based architecture, a good candidate to perform multidomain path computation. In such an architecture, the PCE needs the TED to compute the paths requested by a PCC. In this paper, we explain the approaches of using a OSPF-TE forthe building and maintenance of the TED.
