Abstract
A method and apparatus control a double-ended soft permanent virtual circuit (SPVC) connection coupling from a source end to a destination end via a communications network. The method includes (a) receiving an SPVC connection message from a first network device for the source end, (b) accepting an SPVC connection in accordance with the SPVC connection message if a second network device receiving the SPVC connection has an association with the first network device, and (c) rejecting the SPVC connection if the second network device does not have an association with the first network device. The network device for the destination end includes a database memory adapted to store an access identifier of at least one predetermined source network device from which the network device is allowed to accept an SPVC connection.
