Abstract
A method and apparatus include processing for providing reliable internetworking services that begins by determining whether identified internetworking resources and identified intranetworking resources provide a reliable intranetworking service. For example, the internetworking service may be a communication, data transfer, file share, etc., between two or more users affiliated with different networks. The identified intranetworking resources are those links within each network to support the communication (i.e., the internetworking service) and the identified internetworking resources are those that couple the networks. The processing continues by determining whether the reliable internetworking service cannot be provided due to a failure of one of the identified intranetworking resource. When this occurs, the identified internetworking resources that are associated with the failed intranetworking resource are flagged. Having flagged the associated internetworking resources, a new internetworking service is established using newly identified intranetworking resources and newly identified internetworking resources. Such newly identified intranetworking resources and internetworkin…
