  • TRex Realistic Traffic Generator - Stateless support

    1. 1. New Stateless support
    2. 2. Stateless High level functionality • High scale –~10M-22MPPS/core • Support 1/10/25/40/100* Gb/sec interfaces • Support for multiple traffic profiles per interface • Profile can support multiple streams, scalable to 10K parallel streams • Supported for each stream – Packet template – Field engine program (src_ip = – Send Mode : Continues/Burst/Multi burst support
    3. 3. Stateless High level functionality #2 • Interactive support – GUI/TUI • Statistic per port • Statistic per stream (by Hardware) • Latency Jitter per stream • Fast Python automation support – Python 2.7/3.0 Client API – Python HLTAPI Client API • Multi-user support
    4. 4. Traffic Profile Example
    5. 5. Control plane High level
    6. 6. Multi User
    7. 7. TRex Objects relations
    8. 8. Stateful vs Stateless Feature Stateless Stateful Flow base No Yes NAT No Yes Tunnel Yes Some are supported L7 App emulation No Yes Any type of packet Yes No Latency/Jitter Per Stream Per port/Per flow sample
    9. 9. One stream with two directions
    10. 10. Python automation example Python API
    11. 11. Python HLTAPI Automation
    12. 12. Interactive Console #load the trex as a server for interactive mode $sudo ./t-rex-64 –i #connect to the server from any server ( Python 2/3.4) $./trex-console #start traffic on all port >start -a -m 1 -f stl/ #pause traffic on all port >pause -a #resume traffic on all port >resume -a #stop traffic on all port >stop -a #show dynamic statistic >tui #show port statistic >stats –p #clear statistic >clear #show stream statistic >streams Shell Console
    13. 13. Interactive TUI
    14. 14. Performance Profile name Description Per core performance imix_1pkt 1 stream/64byte 15-22MPPS imix_3pkt_vm 3 streams/IMIX/ip range 50Gb/sec udp_rand_size_9k 1 stream, FE, random packet size 200Gb/sec UCS UCS 240M4 NICS 2xXL710 • Number of streams can scale • Performance depends on many variables. • Field engine can scale to complex scenarios. Has impact on performance
    15. 15. Traffic profile
    16. 16. Simple Interleaving streams
    17. 17. Simple Interleaving streams -profile
    18. 18. Multi streams
    19. 19. Multi burst
    20. 20. Multi burst profile
    21. 21. Field Engine • Flexible engine to change any field inside the packet • Examples – Change TOS 1-20 – Range of client IP – Random packet size 64-9k – Random dest_ip range – Support any tunnel even not valid packet like QinQ/GRE/MPLS/Ipv6/UDP/Ipv4/HTTP • Plan to add even more flexible engine - JITLUA
    22. 22. Field Engine, Syn attack
    23. 23. Multiple Clients example
    24. 24. Multiple Clients profile
    25. 25. Covert pcap packet file to one stream
    26. 26. Pcap file conversion to streams
    27. 27. Pcap file conversion to profile of streams #2 • In this mode pcap in converted to streams and push to TRex server • It won’t work on a big pcap file • There is an API version that push server side pcap file • This version is limited only by server disk size. 1TB pcap file is something that we are using
    28. 28. Teredo tunnel (IPv6 over IPv4)
    29. 29. Per stream statistics • Implemented using hardware assist with Intel X710/XL710 NIC flow director rules • With other NICs (Intel I350, 82599), implemented in software.
    30. 30. Per stream statistics -TOI
    31. 31. Per stream statistics – Python API
    32. 32. Per stream latency/jitter • Base on per stream stats hardware assist • Forward specific type of packets • Filter is based on IPV4.ID and IPv6.flow_id • Software measures latency and jitter resolution is ~usec (not nsec)
    33. 33. Per stream statistics -TOI
    34. 34. Demo Cisco ASR 1013 ESP100 100Gb/sec 13RU - 4KW UCS-220M2 32GB 2x8 cores 2Ghz 2x82559 NIC (4x10Gb/sec) 0.4KW 1RU , 2K$ finalized the GUI
    35. 35. TRex GUI • Desktop application written in JavaFX • Support Windows/Mac/Linux • Like TRex Console gives Stateless functionality – Build a stream from scratch –Scapy like – Control e.g. Start/stop/pause/resume – Live statistics/latency/jitter • Developed by exalt – still under dev
    36. 36. TRex GUI
    37. 37. TRex GUI – Stream builder
    38. 38. Roadmap • Finalized the GUI • FM10K support gives more capability of Per stream statistic • L2 Emulations ARP/IPv6 ND • Routing Emulations BGP/ISIS
