Re: Errors in LAN

[Yuri Pryadkin <yuri@who.isi.edu>]

You can insert an ErrorModel into LAN.  There are different places
where you might place it:

1. On the sender side (e.g. between $ifq_ and $mac_ or before $ifq_).
   Then only packet sent by this sender will be corrupted according to
   the error model you use.  Then all receivers will be dropping
   corrupted packets from this sender at the mac layer.

2. On the receiver side (e.g. between $phy_ and $mac_ - receiver mac
   drops, or $mac_ and $iface_ - but then specify drop-target for
   errormodel, because the errormodel will be dropping packets
   itself).  Only this receiver will have errors no matter who the
   sender is.

3. In a shared part of lan (between $phy_ and $channel_) so all
   packets traversing the lan may be corrupted and dropped by
   receivers at the mac layer.

I guess you can also use ErrorModule to induce flow-based errors
(only between particular source-destination on the lan).  Insert it
the same place as in #1.
