Abstract
This invention discloses a method for migration between a permanent connection and a switched connection in a transmission network. The method comprises the steps of: the ingress node of the current connection receiving a message of connection migrating request; forwarding the message of connection migrating request node by node starting from the ingress node in the direction of the traffic signal transmission of the current connection till the egress node of the current connection; making migration between the two connection modes until the ingress node after the message of migrating request has been received. By making migration between modes of connection node by node at each node of a transmission network, this invention ensures a smooth transition between a permanent connection and a switched connection, effectively avoiding service disruption while making the implementation of network services more flexible.
