Method for building green network

摘要

Provided is a technique for building a green architecture for achieving efficient power saving in a Layer-2 network, the technique having: a packet collection process (S01) for collecting all broadcast packets communicated within the network and extracting packet information; a MAC-IP history generation process (S02) for generating MIPT with the latest timestamp from the packet information; an access analysis process (S03) for counting, on the basis of information about the MIPT, the number of packets per category of {SMAC, DMAC} in each time slot having a certain interval, and generating a MAcT; an L2 switch port analysis process (S04) for generating an MDMAcT on the basis of information about the MAcT; a green architecture building process (S05) for generating a GMDMAcT in which a port connection configuration of the MDMAcT has been updated; and a visualization process (S06) for displaying information about the GMDMAcT.

1. A method for displaying information to a network administrator for altering configuration of the network for achieving efficient power saving in an arbitrary network comprising of L2 switches, said method comprising:
a packet collection process for collecting all broadcast packets transmitted within the network and extracting packet information {Time Stamp(TStamp), Source MAC Address(SMAC), Source IP Address(SIP), Destination IP Address(DIP)} from the broadcast packets; a MAC-IP history generation process for generating a MAC-IP history table (MIPT) with entries {MAC Address(MAC), IP Address(IP), Latest Timestamp(LastTimeStamp)} based on the packet information {TStamp, SMAC, SIP, DIP} extracted by the packet collection process; an access analysis process for generating an access history table (MAcT) with entries {Time Period (TimePeriod), Source MAC Address (SMAC), Destination MAC Address (DMAC), Access Count (Count)}, by classifying packets into categories {Source MAC Address(SMAC), Destination MAC Address(DMAC)} based on MIPT generated by the MAC-IP history generation process and counting number of packets classified into the above categories within a prespecified time slot at regular intervals based on the packet information {TStamp, SMAC, SIP, DIP} extracted by the packet collection process; a L2 switch port analysis process for generating a L2 switch state table (MDMAcT) with entries {Period(HourlyPeriod), L2 switch port (port), Destination MAC Address (DMAC), Access Count (Count)} for every L2 switch, by detecting apparatuses connected to the port of L2 switches and analyzing access counts of the apparatuses within predetermined period based on the MAcT generated by the access analysis process; a green architecture construction process for generating a green L2 switch state table (GMDMAcT) in which L2 switch port configuration of the MDMAcT has been updated, upon detecting a specific L2 switch in which the L2 switch port is in access state (1=
