Abstract
A method is provided for establishing a reliable communication channel between an encapsulation node and a cluster of decapsulation nodes across a communication network. The method is implemented at the encapsulation node and comprises the following steps. A primary session is initialized with a primary decapsulation node in the cluster of decapsulation nodes during which an assigned address is received. A redundant session is initialized with a redundant decapsulation node in the cluster of decapsulation nodes. Data is transmitted to and received from the decapsulation node until a failure is detected. Once the failure is detected, data is transmitted to and received from the redundant decapsulation node instead of the primary decapsulation node.
