Method to provide per-packet load balancing in multi protocol label switching network by assinging multi-label

摘要

The present invention discloses a packet-specific load balancing implementation method in a multi-protocol label switching (MPLS) network using multi-label assignment.;According to an aspect of the present invention, there is provided a method of implementing packet-by-packet load balancing in a multi-protocol label switching (MPLS) network. Generating a forwarding equivalence class (FEC) corresponding to each interface on which the same routing information is received using the same routing information and the interface information; And a third step of generating and assigning a separate label for each FEC. If the paths are different for the same routing information, the packet is transmitted by assigning a different label to each path to transmit the packet. Implement balancing to improve the efficiency of network resources, and create a label route to a specific destination by combining an internal label or EXP bit value with a forwarding label even when interworking with MPLS add-on traffic engineering or virtual private network (VPN) services. Per-packet load balancing can be implemented by using multiple links instead of the same link.
