Title:
PACKET CLASSIFICATION USING MULTI-DIMENSIONAL SPLITTING
Document Type and Number:
WIPO Patent Application WO/2018/153332
Kind Code:
A1
Abstract:
A computer-implemented method classifies a packet received from a network. The method comprises receiving the packet having header information and a rule-set that indicates a plurality of actions to perform on the packet. A geometric representation of the rule-set is constructed having a plurality of dimensions and rule boundaries. At least one rule boundary and dimension of the geometric representation is split to form a search structure having a plurality of nodes. Each node in the plurality of nodes is constrained to a predetermined memory threshold. The search structure is searched using the header information to obtain a rule in the rule-set that indicates an action to take on the packet.
