Abstract (en)
[origin: WO9913619A2] The present invention relates to a lookup device (30) and a method for classification and forwarding of packets. The lookup device (30) comprises i stages (321, 322, 323, 324) wherein each stage (321, 322, 323, 324) represents a predetermined prefix length, and a prefix represents a group of addresses. The lookup device (30) also comprises a routing memory means (34) connected to said i:th stage (324), wherein each stage (321, 322, 323, 324) comprises a memory means (361, 362, 363, 364) for storing a table of entries, wherein each entry comprises a pointer field which either comprises a pointer to the memory means in the next stage, or a pointer to the routing memory means (34) storing the forwarding information.
