<p>Embodiments of the present invention disclose a method, network node, and network system for offloading network traffic. The method includes: obtaining link utilization information of a network; computing a shortest path and a second shortest path to a content source; selecting a light-load path from the shortest path and the second shortest path according to the obtained link utilization information; and selecting traffic and dispersing the selected traffic onto the light-load path. By implementing the present invention, a light-load path can be selected according to link utilization information of a network, and traffic is dispersed over the light-load path. In this way, dynamic load balancing of traffic is implemented, thereby preventing or mitigating network congestion.</p> |
