[Click] Write handler problem

[Daniel Henkel]

Marco,

one possible solution would be to introduce a central
information/configuration element which gets queried by all ICMP
advertisers. You would only change the parameter once in that element
and all others get notified of the change or query in a set interval.
One example is given in elements/analysis/aggregateipflows.hh, and
related elements like ToIPFlowDumps (elements/analysis). (There was an
email by Eddie on this subject some time ago.)

Cheers,
- Daniel.
