Abstract
A generalized multiprotocol label switching (GMPLS) non-enabled network gateway for routing between a GMPLS enabled network and a GMPLS non-enabled network for connection between the GMPLS enabled network and the GMPLS non-enabled network, and an operating method for the GMPLS non-enabled network gateway are provided. The GMPLS non-enabled network gateway may include a border gateway protocol (BGP) routing unit to exchange routing information between a first GMPLS enabled network and a third GMPLS enabled network using a BGP, and a resource reservation protocol signaling unit to search for a path to another network using the routing information and to perform inter-autonomous system (AS) signaling by including a control plane of the first GMPLS enabled network or the third GMPLS enabled network and a signaling interface applying an out-of-band method.
