[net2-wg] Re: Link table management

[Rodrigo Fonseca]

There are two different things that we can do.

The first is to request that an entry be created for a node. This may
or may not be special. It is more like saying: LinkEstimator, make
space and get info about this node.

The second is what you say, some form of "pinning" the neighbor to the
table. SP's approach in that case, as far as I remember, is to say:
well, if your important neighbor has been evicted, tell the table to
insert it again.

The latter approach may lead to churn if there are conflicting goals, I think...
