摘要： A method for identifying a Stream Control Transmission Protocol (SCTP) packet is provided, which includes: acquiring a feature tuple of a received SCTP packet, in which the feature tuple includes at least one piece of the following information: a source Internet Protocol (IP) address, a destination IP address, and a verification tag (V_tag); matching the acquired feature tuple of the SCTP packet with a SCTP tuple identification table, in which the SCTP tuple identification table includes a mapping relation between a feature set tuple and an SCTP association, and the feature set tuple includes at least one piece of the following information: a source IP address set, a destination IP address set, and the V_tag; and acquiring an SCTP association to which the SCTP packet belongs, if the acquired feature tuple of the SCTP packet matches one or more records of the SCTP tuple identification table. Correspondingly, a device for identifying an SCTP packet, a system for identifying an SCTP packet, and a method for establishing an SCTP tuple identification table are further provided, capable of reducing missed identification of an SCTP stream.
