• Recently, integration of multiple network domains, such as optical fiber domains and packet domains, has been required by network providers and users. To achieve this interdomain integration, generalized multiprotocol label switching (GMPLS) is now receiving more attention. One of the main features of a GMPLS network is its multilayered complexity, which sometimes places a large burden on source GMPLS routers to determine optimal routes to destinations in other domains and causes label switching path (LSP)-setup delays. To reduce this source-router burden, we propose hierarchically distributed path computation equipment (HDPCE) that cooperates with each other to determine interdomain routes, reduce setup delay, and conduct flexible interdomain route creation taking individual GMPLS domain routing policies into consideration. Each domain routing policy can be set independently from that of other domains, and this routing information is not revealed to other peer domains because each HDPCE is allocated to every domain, including an interdomain, which has several underlying domains under it. Each underlying domain's HDPCE flexibly chooses three types of routing policies depending on the domain's requirement, and the interdomain HDPCE conducts interdomain route creation in accordance with underlying domain policies. OSPF routing protocol is now being applied to interdomain routing on GMPLS networks. Therefore, we compare the proposed HDPCE-based interdomain route creation with OSPF-based route creation in terms of performance and applicability, and we evaluate the effects of each underlying domain policy on interdomain route creation.
