MIXED ACTIVE NETWORK MODEL AND PACKET PROCESSING METHOD IN ACTIVE NETWORK MODEL

摘要

PURPOSE: A mixed active network model and a packet processing method in an active network model are provided to classify packets into an 'Aflow' packet, a 'non-Aflow' packet, and a 'sigAflow' packet according to the continuity of a packet delivery cycle, so as to actively load resources necessary for performing active packets on an active node. CONSTITUTION: If an optional packet is received to a packet classifier(S200), the packet classifier decides whether a protocol field of a header of the packet is set as active(S202). If not, the packet classifier regards the received packet as a general IP(Internet Protocol) packet(S204), and if set as active, the packet classifier regards the received packet as an active packet(S206). The active packet is provided to a flow classifier(S208). The flow classifier decides whether the packet matches with a demux key field(S210). If so, the flow classifier classifies the packet as an 'Aflow' packet(S212). If the packet does not match with the demux key field, a performance environment block detects a type field of the active packet header(S214). If a detected type value is '0'(S216), the performance environment block classifies the packet as a 'sigAflow' packet(S218). And if the detected type value is '2'(S220), the performance environment block classifies the packet as a 'non-Aflow' packet(S222).
