CP and Full MSR Test Status

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


John DeHart- 04/20/23 19:14

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


John DeHart- 04/20/23 19:14

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


John DeHart- 04/20/23 19:14

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?

Serial Ports for MSR 0• SPC 0: cvs.arl.wustl.edu (demand1): > tip spc0

• SPC 1: cvs.arl.wustl.edu (demand1): > tip spc1

• SPC2: spode: > tip spc1

• SPC3: spode: > tip spc0

• SPC4: demand4: > cu –s 9600 –l ttyS0

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}

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).
