Title:
DEVICE AND METHOD FOR MULTIFLOW QUANTILES EXTRACTION AND RECONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2023/173343
Kind Code:
A1
Abstract:
A network device (400) for extracting quantiles of a set of one or more flows. The network device (400) is configured to, for each packet belonging to a flow of the set of flows: extract a flow identifier (401) and a measurement value (402) of the flow; derive an index (403) of a bin corresponding to the extracted measurement value (402); generate a per-flow bin identifier (404) based on the flow identifier (401) and the index (403) of the bin; update a per-flow bin entry (405) that corresponds to the per-flow bin identifier (404) and that is stored in a first data structure (410) by increasing a value of the per-flow bin entry (405) by 1; and store the per-flow bin identifier (404) in a second data structure (420). A control plane entity (600) for reconstructing quantiles of a set of one or more flows.
