Cross-chip data stream forwarding method and device

The invention discloses a cross-chip data stream forwarding method. The method comprises the following steps: acquiring a storage utilization rate of a forwarding chip according to a preset period; when the storage utilization rate is smaller than a preset threshold value, sending a cross-chip path distribution pause instruction to the forwarding chip so as to pause cross-chip path distribution; after the forwarding of the path-allocated message cached by the forwarding chip is completed, updating a routing parameter stored in a Hash routing system register of the forwarding chip according to a preset updating rule; and after the routing parameters are updated, sending a cross-chip path allocation opening instruction to the forwarding chip so as to open cross-chip path allocation. According to the embodiment of the invention, the problem of packet loss caused by non-uniform distribution of data stream cross-chip forwarding paths in the prior art can be solved. 本发明公开了一种跨芯片的数据流转发方法，该方法包括：按照预设周期获取所述转发芯片的存储利用率；当所
