Abstract
A method of and a device for enabling load balancing for Multiprotocol Label Switching Transport Profile (MPLS-TP) are provided. The method is applied to a process of transmitting data between two Provider Edge (PE) devices that adopt a protection mechanism of primary and backup tunnels. The method comprises allocating, by a source PE device located at a head node of a tunnel, traffic to each of the primary and backup tunnels in a current transmission period based on transmission performance information about each of the primary and backup tunnels in a previous transmission period fed back by a destination PE device located at a tail node of the tunnel, when a set transmission period comes; and obtaining, by said source PE device, the traffic allocated to each of the tunnels and transmitting data to the destination PE device via the corresponding tunnels.
