block.p4

This repo presents the P4-based network function blocks based on "l2_switch.p4". We create the environment to test these blocks by using mininet simulation tools.

Requirements

  • mininet;
  • bmv2;
  • p4c-bm.

Supported Blocks

  • 0.features in p4src
  • 1.port security
  • 2.icmp security
  • 3.udp flooding
  • 4.port mirroring
  • 5.resubmit
  • 6.multicast NAT
  • 7.trTCM
  • 8.ECMP
  • 9.TCP SYN/FIN check

Demo

  • "http_icmp_udp": The http_icmp_udp is an explaination example that one switch enabled the http security feature and another switch provides both the icmp and udp security functions. See http_icmp_udp.
  • "sswitch": The sswitch united all the blocks in one P4 switch pipeline, see sswitch for more informations.
  • "DDoS": The DDoS showed that how to simply defense the SYN/FIN/UDP DDoS attack with trTCM and TCP check. See DDoS.

Next Steps

Our following works focus on the combination between NFV SFC and P4 language. For more details, try this repository: OpenP4SC.
