Network gateway and routing method with equal-cost multi-path routing dynamic adjustment mechanism

Abstract

A network gateway and a routing method with an equal-cost multi-path (ECMP) routing dynamic adjustment mechanism are provided. The routing method includes: obtaining an ingress packet of an ingress traffic through a network interface of a network gateway; retrieving packet information of the ingress packet and calculate a forwarding decision parameter through a traffic forwarding decision function; continuously obtaining a plurality current queue statuses for a plurality of ECMP member egress ports of an ECMP group; and selecting one of the ECMP member egress ports to forward the current traffic based on the forwarding decision parameter and the current queue statuses.
