Washington WASHINGTON UNIVERSITY IN ST LOUIS CP and Full MSR Test Status

2 Washington WASHINGTON UNIVERSITY IN ST LOUIS John DeHart- 11/22/2015 9:59 AM CP Status Ported to Linux (still works on NetBSD) –Previous WUGS tools already worked on both –newGBNSC.init and newGBNSC (read only) Do NOT use old GBNSC anymore! –sendcmd – MSR configuration and control utility Other changes and things to do: –sendcmd – MSR configuration and control utility Used by configuration module via script All output now controlled via verbose flag (-v) –AAL5download – SPC kernel downloader Uses the APIC User space library installed in: –wu_arl/utilities/lib/{Linux,NetBSD}/libAPIC.a To Do: Better error checking

3 Washington WASHINGTON UNIVERSITY IN ST LOUIS John DeHart- 11/22/2015 9:59 AM CP Status (continued) –AAL5Generator – traffic generator Uses the APIC User space library installed in: –wu_arl/utilities/lib/{Linux,NetBSD}/libAPIC.a DONE: Add interface for on-the-fly changes: –Stop transmission: suspends APIC transmit channel –Start transmission: resumes APIC transmit channel –Change destination address: update buffer memory with new dst »For this we may want chain to be only one desc/buffer. –Change transmission rate: change per VC pacing parameter –Quit: program exits DONE: Command line argument changes –DONE Packet size instead of index –DONE Make packet size continuous up to full MSR buffer size. DONE: buffer usage: –DONE Have it use one buffer of full MSR buffer size –DONE Set size fields based on command line arguments: »IP Header »AAL5 Trailer »Descriptor

4 Washington WASHINGTON UNIVERSITY IN ST LOUIS John DeHart- 11/22/2015 9:59 AM CP Status (continued) Configuration module –Functions: reset WUGS (causes reset of all SPCs) Configure WUGS with MSR VCs MSR component discovery (SPCs, line cards, …) –Build objects to represent ports Download SPC kernels (via system( ) of shell script) –To Do: integrate into Configuration module code??? Initialize SPC kernels (via system( ) of shell script) –To Do: »integrate into Configuration module code »Extend sendcmd functions and install as a library

5 Washington WASHINGTON UNIVERSITY IN ST LOUIS John DeHart- 11/22/2015 9:59 AM CP Status (continued) Configuration module (continued) –To Do: Overall MSR configuration file –Router/IP information –Information to control SPC kernel initialization phase Make kernel download/initialization dependent on discovery Integrate SPC kernel initialization Make configuration module a thread FPX integration –Discovery –Downloads: »What, where and how? –Initialization: »What, where and how? –Schedule?

8 Washington WASHINGTON UNIVERSITY IN ST LOUIS John DeHart- 11/22/2015 9:59 AM General Comments Linux cvs seems to be a little different –CVS/Repository does not get the full path, missing /b/cvsroot Two sets of binaries –./$(OSTYPE) directory in source directory Change in Makefiles for Linux and NetBSD –Different include paths and files –Different library paths and files –Sometimes different gcc flags –Use OSTYPE environment variable Linux shells use this inconsistently, therefore, use: –make OSTYPE=Linux Install targets and directories –wu_arl/utilities/bin/{Linux,NetBSD}/ Each contains AAL5Generator,AAL5_download.sh, … –wu_arl/utilities/lib/{Linux,NetBSD}/libAPIC.a –wu_arl/msr/bin/{Linux,NetBSD}

11 Washington WASHINGTON UNIVERSITY IN ST LOUIS John DeHart- 11/22/2015 9:59 AM CP Configuration File ( continued ) # MSR Routing Neighbors # Since protocols like OSPF behave differently on broadcast, # point-to-point and non-broadcast multi-access networks # we list the proto type here. Also, we need a way to # bind IP router's IP address (next hop as in an intermediate # node and not the final destination) to a MAC address. The problem # is on broadcast networks (our GigE interface) where the packet's # destination address is the final end-station and not the intermediate # router's address. These entries provide a mapping from next hop router # to MSR SubPort (SubPort maps directly to an outbound VCI on the # interface).
