SALCEDO, Octavio; LOPEZ, Danilo  e  HERNANDEZ, Cesar. Protocol evaluation (OSPF-TE and BGP) regarding autodiscovery mechanisms in L1VPN over GMPLS. Tecnura [online]. 2012, vol.16, n.33, pp.131-144. ISSN 0123-921X.

GMPLS (Generalized Multiprotocol Label Switching Architecture) is a new Framework of protocols which is not only an extended version of MPLS. Instead of that It is a specialized group of protocols to discover neighbors, discover link state information, topology management, route management, load balancing, centralized control, bandwidth on demand management and management of VPNs (Virtual private networks) in physical-optical level through the use of adequate optical devices. In this paper are evaluated the results of a simulation for autodiscovery mechanism for a layer one VPN using the OSPF-TE and BGP protocols and comparing them. This paper pretends to give a vision to the reader of the potential of GMPLS framework and analyze the advantages and disadvantages to use OSPF-TE instead BGP for autodiscovery purposes in a layer one virtual private network for an specific network scenario.
