BARRETO PRIETO, Osmel. VPLS: alternative of interconnection through ETECSA´s IP/MPLS backbone. Rev cuba cienc informat [online]. 2013, vol.7, n.1, pp. 32-43. ISSN 2227-1899.

The Cuban Telecommunications Enterprise (ETECSA) owns exclusively the whole telecommunication infrastructure in the country. Because of that, other services providers need to use its network as a support for the interconnection of the nodes which form part of its own networks. Attending to the development of telecommunication technologies, ETECSA has invested on the implementation of an IP/MPLS (Internet Protocol over MultiProtocol Label Switching) backbone for its network, which is supposed to absorb all the services that are supported by the ATM (Asynchronous Transfer Mode)/Frame Relay backbone. However, at the moment this network supports level three services (according to OSI model), which is unacceptable for the other providers, due to the management requirements of the routing policies of the services they provide. This article describes a proposal of implementation of a VPLS (Virtual Private LAN Service) entity as an alternative for the migration of the level two VPN services that are supported at present over the ATM/Frame Relay backbone, toward the IP/MPLS backbone. This entity guarantees the operation and routing independence for the service providers that are clients of ETECSA.

Palabras clave : IP/MPLS; VPLS; migration; routing independence.
