Hello, I am a rather new user to OpenSolaris and I have been loving every minute of it. I have spent quite a lot of time looking around for bandwidth management features and Project Crossbow is just amazing. It is truly amazing compared to what Linux has to offer. I would like to use flowadm to do some bandwidth management on a tun interface. The problem is that it is not recognized by the dladm utility. It appears in *ifconfig -a* but not in *dladm show-link*. Is this normal ? Did I miss something ? Since my tun interface is not recognized by dladm, I am unable to use the flowadm ut...

Among other things, I run an http server on my home DSL line (6M/768kbit). The content includes several large image galleries, and when certain crawlers hit our server w/ multiple large image uploads, we end up with large ping time delays - sufficient to disrupt the kids'' on-line gaming. Attempts to control this with robots.txt has not be very successful; Solaris IPQoS appears quite

Hi all, As part of IPv6 version specific classification support in crossbow we are introducing ip_version option in flowadm interface and associated classification functions. If ip_version option is not specified, but v4 or v6 address is passed as arg. to ip_addr option of flowadm cli that can also help to populate version specific bits in flow_mask to specify if policy (and flow entry instance) is for IPv6 type flow...

...better visibility into network traffic in light of crossbow features like virtual NICs, interrupt vs. polling modes etc. This in turn would greatly assist network performance analysis. It is also aimed at segregating link/flow configuration from dynamic network statistics. In particular, - dladm/flowadm would retain configuration specific commands for links/flows while dlstat/flowstat would provide interfaces for displaying dynamic network statistics. - show-usage would be removed from dladm/flowadm and would become part of dlstat/flowstat. It would be renamed show-history. - Rich set of counter...

...ions about modifying bandwidth for flows/VNICs. I believe that should be fine in the recently released bits, could you please check and lets know if you still have any questions about this. Bandwidth limits can be modified using: links: dladm set-linkprop -p maxbw=<value> linkname flows: flowadm set-flowprop -p maxbw=<value> flowname (I tried netperf after modifying a flow''s bandwidth and it worked fine. If you want us to try some example let us know.) I remember you had questions about monitoring the usage, is that the one? thanks, -venu

Actually, it is not a list.. but just something that''ll be very useful to me in my business. If crossbow/virtual interfaces can provide a flow that can capture bandwidth usage over a period of time (including 95 percentile), that''ll be great! Is this possible? -- This message posted from opensolaris.org

Following is a short description on assigning priorities to a link (via dladm). Flows will have a similar mechanism (via flowadm). thanks, -venu ---------------------------------------------------------------------------- The components associated with a link or flow, such as Soft Ring Sets, Soft Rings and squeues, have kernel threads processing inbound/outbound packets. The scheduler processes threads based on a thread...

Hi all, Link protection is a new feature we are planning to introduce to Solaris and we would like to solicit your feedback on it. Please see attached document for details.

Folks, I just posted an updated Crossbow virtualization architecture document. The new revision is available at: http://opensolaris.org/os/project/crossbow/Docs/crossbow-virt.pdf The main changes are the addition of support for multiple MAC addresses per client, and an explicit separation between consolidation private and project private MAC API entry points. See in particular the
