WEIGHTED COST MULTIPATH PACKET PROCESSING METHOD AND DEVICE

The invention relates to weighted cost multipath packet processing method and device. A method includes receiving a network packet for routing through one of a number of paths of a network switch device. The method also includes selecting, via a first function applied to the network packet, a record from a plurality of records corresponding to the number of paths, wherein each of the plurality of records includes a threshold, a first routing index, and a second routing index. The method also includes determining, via a second function applied to the network packet, a routing value within a predefined range of values. The method also includes choosing, from the selected record, the first routing index or the second routing index based on whether the routing value meets the threshold of the selected record. The method also includes routing the network packet based on the chosen routing index. 本申请案涉及用于加权成本多路径包处理的方法及装置。一种方法包含接收网络包以通过网络交换机装置的一定数目个路径中的一者路由。所述方法还包含经由应用于所述网络包的第一函数从与所述一定数目个路径对应的多个记录选择一个记录，其中所述多个记录中的每一
