  2. Project Objectives Control Processor External Switch CP GPE GPE NPE • Deploy five experimental overlay hosting platforms • located at Internet 2 PoPs • compatible with PlanetLab, moving to GENI control framework • performance characteristics suitable for service deployment • integrated system architecture with multiple server blades • shared NP-based server blades for fast-path packet processing • Demonstrate multiple applications netFPGA ExternalSwitch Chassis Switch General Purpose Processing Engines Network Processing Engine Line Card Line Card Chassis Switch 10x1 GbE

  3. Target Internet 2 Deployment 2 2 2 1 2 1 2

  4. Status • First three nodes deployed and operational • installation went smoothly (mostly) • two hardware issues • replaced KC linecard, still need to replace one GPE at SALT • Demonstration this afternoon • Ready for a few friendly users • still need to complete flow stats • version 1 of NPE software • not yet ready to add fastpath code options • but happy to start working with interested groups • Tutorial planned for next GEC • let me know if you’re interested

  8. Demonstrations this Afternoon • IPv4 network using NP-based fastpaths • traffic generated from PlanetLab nodes • demonstrates dynamic changes to installed filters • script in GPE slice issues control messages to modify filters • handling of exception cases by GPE slice • use of traffic monitoring • Forest overlay network – GPE-only implementation • multiple dynamic multicast groups over per-session,tree-structured communication channels • traffic generated from PlanetLab nodes • traffic monitoring using statistics data generated byGPE slice

  10. Forest Overlay Network client accessconnection • Focus on real-time distributedapplications • large online virtual worlds • distributed cyber-physical systems • Large distributed sessions • endpoints issue periodic status reports • and subscribe to dynamically changing sets of reports • requires real-time, non-stop data delivery, even as communication pattern changes • Per-session communication channels (comtrees) • unicast data delivery with route learning • dynamic multicast subscriptions using multicast core server overlayrouter comtree

  12. Developing a new SPP Application • Create reference model as foundation • work out functional issues • develop and debug control code • build with separate control and datapath processes • implement in Open Network Lab or Emulab • Port reference model to SPPs using GPEs only • initially, just reproduce reference model functionality • extend to use multiple external interfaces, reserved capacity • Design new NPE code option • we’ll work with you and do NPE code development • need working GPE version and fastpath design spec

  13. Working with SPPs • Define new slice using SPPLC • much as with PlanetLab • Login to GPE slice to install application code • Reserve resources needed for your experiment • includes interface bandwidth on external ports and NPE fastpath resources • To run experiment during reserved period • configure reserved resources as needed • setup logical endpoints (aka meta-interfaces) • configure fastpath (filters, queues) • setup real-time monitoring • run application and start traffic generators

  15. Steps in Setting Running Experiment • Reserve resources in advance • At start of session • configure logical interfaces (aka meta-interfaces) • associate with physical interfaces and port numbers • assign bandwidth • setup fastpath • assign queues to logical interfaces, set queue parameters • install fastpath filters • setup traffic monitoring • At end of session • release resources in use • cancel any remaining reservation time

  16. Command Line Tools • resrv– reserve resources in advance • make_resrv,update_resrv,cancel_resrv,get_resrv,... • client– perform variety of operations • get_ifaces ,get_ifattrs • get_queue_params, set_queue_params, bind_queue • alloc_endpoint, alloc_tunnel • write_fltr, update_result, get_fltr_bykey • read_stats, create_periodic, get_queue_len • create-fp– instantiate fastpath • fltr– manipulate fastpath filters for IPv4 code opt • sliced – monitor traffic and display remotely

  17. Reserving Resources in Advance • resrv --cmdmake_resrv --xfileresFile <spp> <rsvRecord> <rDate start="20091117140000" end="20091117160000" /> <fpRSpec name=“jstFastpath"> <fpParams> <copt>1</copt> <bwspec firm="1000000" soft="0" /> <rcntsfltrs="100" queues="10" buffs=“1000" stats=“20" /> ... </fpParams> <ifParams> <ifRecbw=“20000" ip="64.57.23.194" /> ... </ifParams> </fpRSpec> <plRSpec> <ifParams> <ifRecbw="10000" ip="64.57.23.194" /> </ifParams> </plRSpec> </rsvRecord> </spp> reserved time period aggregate fastpath bandwidth # of TCAM filters, queues, packet buffers, traffic counters bandwidth on external interfaces, specified by IP address external interface bw for GPE slice

  18. Configuring Logical Interfaces setup externally visible port • For use by GPE slice • client --cmdalloc_endpoint --bw 1000 --ipaddr 64.57.23.210 --proto 6 --port 3551 • For use by fastpath • client --cmdalloc_udp_tunnel --fpid 0 --bw 16000 --ipaddr 64.57.23.210 --port 20001 in Kb/s address of interface 6 for TCP, 17 for UDP port number identifier of fastpath within this slice

  19. Configuring Fastpath • Binding queues to logical interfaces • client --cmdbind_queue --fpid 0 --miid 1 --qid_list_type 0 --qid_list 4 --qid_list 6 • Setting queue parameters • client --cmdset_queue_params --fpid 0 --qid 3 --threshold 1000 --bw 8000 • Setting up filters (for IPv4 fastpaths) • fltr --cmdwrite_fltr --fpid 0 --fid 10 --key_type 0 --key_rxmi 2 --key_daddr xx --mask_daddr xx --key_dport xx –-txdaddr xx --txdport xx --qid 5 meta-interface id assigned queues

  20. Displaying Real-Time Data GPE CP NPE GPE SCD-N Line Card sliced • Fastpath maintains traffic counters and queue lengths • To display traffic data • configure an external TCP port • run sliced within your vServer, using configured port • /sliced --ip 64.57.23.194 --port 3552 & • on remote machine, run SPPmon.jar • use provided GUI to setup monitoring displays • SPPmon configures sliced, which polls the NPE running the fastpath • SCD-N reads and returns counter values to sliced • can also display data written to file within your vServer SPPmon

  21. Summary • SPPs ready for use • start with a few friendly users, but will open up soon • tutorial at next GEC • To do list • complete flow stats subsystem • version 2 of NPE software • higher performance and multicast support • resource allocation mechanisms • enable coordinated reservation across all nodes • work with user groups on new code options
