Re: Re: xPLHAL INSTALL

[Frank Mc Alinden]

Hi Kevin
Thanks for the clarification....I assumed the whole message had to
be checked....In my code i am still looking for the hop= but ignore the
value...as im comparing the received data to a lookup table it makes it
easier
(for me anyway) to leave it in.......Just a few questions hoping you can
clear
some other things i may have got wrong......Does an osd device need to know
exactly the source of a message..?? I would have thought its only concerned
if
its targeted at it or its a broadcast message ??..Theres obviously lots of
devices that could be the source of a message ..and thats a lot of coding
for a
little pic....


Thanks
Frank

Frank,

The hop= simply reflects the number of bridges that the message has
passed through on its route to you. It is incremented by an application
that
provides either a forwarding or routing function. It is used to stop a
message being endlessly propagated on a network, effectively such an
application stops forwarding (drops) messages where the hop= has reached a
certain threshold level. If there was a circular connection is some large
network this could lead to such an endless loop. You could also use this
feature such that only adjacent or near network messages were relayed if
that was your intent.

In your application you should probably totally ignore the incoming
hop values and when you send a message originate it with a hop=1.
