[ug-bosug] BOSUG Meeting - 5-April - Session on crossbow

[venugopal iyer]

Thanks for setting this session and to those you attended!

As I mentioned towards the end of the talk, at the end of this mail is
a list of enhancements that folks interested in development can take a
look (this is a partial list, we plan to  update the crossbow page
on opensolaris - http://opensolaris.org/os/project/crossbow/ to
make this list available)

[Please subscribe using crossbow-discuss-subscribe at opensolaris.org to
keep track of the progress of crossbow]

The current source  is available as netvirt-src-20080310.tar.bz2 from
http://opensolaris.org/os/project/crossbow/snapshots (we are working
on making the mercurial gate available) along with binaries.

thanks,

-venu

Low complexity
-----------------

Add dtrace probes for flows

Need  mdb walkers for the flow table and rings

flowadm remove-flow -l link does not work

Suport direction aware resource controls

Support ranges of port numbers with flow specifications

Add the '-v' option to flowadm/dladm show-usage

xVM config tools need to pass a string name  for vnics they  create

use mod_hash_t instead of ad-hoc mac_chain_t for chaining ring descriptors

Bypass queuing/bandwidth controls for latency sensitive packets like heartbeats


Medium complexity
-----------------

Implement RED policy for crossbow

Add diff-serv flowID on outgoing packets

libdladm config/stat API

Support OR rules for flows classification

dladm show-dev should display h/w resources

Add SNMP support for flows

Support flows from non global zone

Need a detection and self recovery mechanism for transcient flows startup failures

High complexity
---------------

need hardware classification support for subflows

Link and flow properties for workload characterization

Support sub-megabit bandwidth limits

Add/remove ring to/from groups driver entry points

Support for  Bandwidth Guarantee

Layer 7 Classification

Support migration of VNICs

Transparent/automatic VNIC creation during Zone booting (a la Xen)
