Hi Rob and Nick,
The following seems to be a problem with FlowVisor.
In the spec, vendor extension such as OFPST_VENDOR and OFPAT_VENDOR is
defined as 0xffff. However, FlowVisor has tables that doesn't assume
0xffff (or -1 in signed short). For example:
static final Class convertStatsRequestMap[] = {
FVDescriptionStatistics.class, FVFlowStatisticsRequest.class,
FVAggregateStatisticsRequest.class, FVTableStatistics.class,
FVPortStatisticsRequest.class, FVQueueStatisticsRequest.class,
FVVendorStatistics.class };
Since FVMessageFactory.getStatistics() in OpenFlowJ actually returns
-1 (0xffff), the caller(FlowVisor) should convert it to 6 (or the last
entry of the table) for accessing convertStatsRequestMap[]. Potentially,
there are same problems in accessing convertStatsReplyMap[] and
convertActionsMap[], I guess.
I haven't prepared a patch for this problem this time. Sorry.
Best regards,
Masahiko.
