Kind Code:
A1
Abstract:
Provided in the present application are a buffering method and an integrated circuit, which can avoid a false hit. The buffering method comprises: acquiring a first packet, wherein the first packet comprises a destination internet protocol (IP) address; searching a buffer for a routing prefix that matches the destination IP address; in response to the fact that the routing prefix is not stored in the buffer, searching, according to the destination IP address, for a tree structure corresponding to a routing table, and determining a prefix node that matches the destination IP address; in response to the fact that the prefix node is not a leaf node, a processor determining a first prefix match length, wherein the first prefix match length is equal to the length between a root node and a tail node of the tree structure; determining a first routing prefix according to the first prefix match length and the destination IP address; and triggering the buffer to store a first correspondence, wherein the first correspondence is a correspondence between the first routing prefix and routing information that corresponds to the prefix node.
