The application discloses a kind of based on the quick flow identification and
cache optimization method of
heterogeneous network element equipment, it is related to the technical field of super high speed programmable data plane, wherein the method includes: original traffic is collected and
feature extraction, constructs packet level and flow level
feature set, and the structured flow
feature vector that
heterogeneous network element can be uniformly identified is compressed by deterministic integer operation generation;Based on the vector, construct extended flow state table, combined with
native state table to establish two-level
joint management mechanism, complete table entry
insertion, update, aging and priority replacement;According to deterministic trigger rule, by programmable switching
chip, flow key and
feature vector are packaged and reported to
field programmable gate array, realize remote state maintenance and result back, finally achieve high deterministic collaborative flow identification and
cache optimization.The application realizes line speed forwarding and feature real-
time synchronization by data plane deterministic pipeline
processing, solves the problem of high flow identification
delay and low efficiency.
