The method comprises using the first access node to assign a temporary identification to the wireless communication device, causing the second access node to identify the first access node from which the temporary identification originates and hiding the mobility of the wireless communication device from the network when routing traffic to a serving access node of the first and second access nodes based on the identified first access node and the temporary identification. In one embodiment, use of software at these access nodes may enable deploying of a centralized logical functionality instead of centralized physical nodes.

Abstract: A technique for managing loops between network devices such as customer and carrier edge devices involves monitoring the MAC moves that occur at a device to detect the existence of a loop and initiating a loop protection action if the MAC moves indicate that a loop exists. The number of MAC moves that indicates the existence of a loop is user programmable and pre-established in the device configuration. The number of MAC moves can be expressed as a MAC move threshold, which is defined in terms of, for example, a MAC move rate or a number of MAC moves. Typically, the loop protection action that is initiated in response to a detected loop involves blocking the flow of the looping packets at the corresponding device.
