Figure 1-16. Outbound Connection Reservation Implication
■ If the current connection count from Zone1 is 10,500 (500 connections of
which are reserved), and 500 non-reserved connections are closed, then
the Zone1 limit will revert to its original limit of 10,000. At this point the
Zone1 maximum connection threshold (10,000) already provides for the
reserved connections. Any other new connections from Zone1 will not be
successful. However, if the connection limits for other zones have not
been reached, new connections can be made from those zones.
Inbound Example. In an inbound reservation, you are reserving connec-
tions from the specified zone to the specified IP address or addresses.
Suppose the same four zones as in the previous example have the same limit
of 10,000 each. The global maximum connections limit remains at 40,000 (4x
10,000).
