Some programs of thesis uesd for flow traceback

1 flow statistic

step 0：run the flow.p4 to config the P4 switch

P4@P4: cd/flow
P4@P4: make

step 1：run the flowtest.py to generate the test flow

run the flowtest.py

P4@P4:./flowtest.py n

step 2：run the holt.py to predict the flow statistic

./holt.py

2 flow traceback

step 0：run the traceroute.p4 to config the P4 switch with p4 info and json

terminal 1

P4@P4: cd/traceroute
P4@P4: make
mininet> xterm h4 h2

step 1：run the receive.py to receive the test flow

xterm

root@P4: ./receive.py

root@P4: ./send.py 10.0.2.2 "come from h4" n

terminal 2

P4@P4: cd/fragment
P4@P4: make
mininet> xterm h4 h2

xterm

root@P4: ./receive.py

root@P4: ./test.py 10.0.2.2 "come from h4" n

3 Smart Contract

generate the testnet of blockcahin in cache by ganache-cli

P4@P4:ganache-cli -q

terminal 1 deploy the contracts by javascript

P4@P4: node deploy.js

terminal 2 call the contracts

P4@P4: node call.js

terminal 3 get the event based logs

P4@P4: cd/eth/dapptest/ddostest/ddosdapp
P4@P4: ~/eth/dapptest/ddostest/ddosdapp$ npm start
