    121 === 4d. Download the pox apps ===
    122 To help you get started with your controller writing, we will provide:
    123   * skeleton files for the controllers where you only need to complete some missing functionality
    124   * the solution: fully implemented controllers
    125   * a utility library that makes some of the pox messages easier to write
    126 
    127 '''In the controller terminal execute''':
    128 {{{
    129   cd /tmp/pox/ext
    130   wget http://www.gpolab.bbn.com/experiment-support/NFVApps/pox-intro-ctrlapps.tar.gz
    131   tar xvfz pox-intro-ctrlapps.tar.gz
    132 }}}
    133 ==== Useful Tips for writing your controller ====
    134 
    135 In order to make this first experience of writing a controller easier, we wrote some helpful functions that will abstract some of the particularities of POX away.
    136 These functions are located in `/tmp/pox/ext/utils.py`, so while you write your controller consult this file for details.
    137 
    138 Functions that are implemented include:
    139   * packetIsIP : Test if the packet is IP
    140   * packetIsARP : Test if the packet is ARP
    141   * packetIsRequestARP : Test if this is an ARP Request packet
    142   * packetIsReplyARP : Test if this is an ARP Reply packet
    143   * packetArpDstIp : Test what is the destination IP in an ARP packet
    144   * packetArpSrcIp : Test what is the sources IP in an ARP packet
    145   * packetIsTCP : Test if a packet is TCP
    146   * packetDstIp : Test the destination IP of a packet
    147   * packetSrcIp : Test the source IP of a packet
    148   * packetDstTCPPort : Test the destination TCP port of a packet
    149   * packetSrcTCPPort : Test the source TCP port of a packet
    150   * createOFAction : Create one OpenFlow action
    151   * getFullMatch : get the full match out of a packet
    152   * createFlowMod : create a flow mod
    153   * createArpRequest : Create an Arp Request for  a different destination IP
    154   * createArpReply : Create an Arp Reply for  a different source IP
