Connection Capacity
The term connection capacity refers to the number of outstanding host requests that
can be associated with a given connection. The following choices are supported:
The capacity parameter is specified as follows. Only one of these options is allowed.
If neither of them is specified or if the value is greater than or equal to 254, the
connections have unlimited capacity (the default). If the VTCPD daemon is to serve
phone lines with numbers greater than 254, its -p / -P option must be increased to
exceed the maximum line number.
Capacity Description
Unlimited There is no limit to the number of outstanding host requests that can
be associated with each link.
Limited Each connection has a pool of slots, which are allocated to phone
lines by VTCPD.
Common
Pool
All host links have a common pool of slots, which means that the
total number of outstanding host requests is limited.
vtcpd [{-p <#>|-P <-|#>}] [-m R]
Args: -p Lowercase "p" specifies limited capacity, where each connection
has a pool of slots.
-P Uppercase "P" specifies a common pool of slots for all connections.
The default is unlimited, indicated by a dash (-).
-m R Specifies that VTCPD chooses the connection and the
corresponding slot in the pool using round robin load balancing
(instead of the default method of round robin balancing among slots
with the minimum number of outstanding requests.) If all slots are
used the request is rejected.
Examples: vtcpd -l 20:mpshost:1000 -P 20
Specifies a common pool of 20. It is possible that all 20 requests will be sent
through one connection, leaving all other links idle.
vtcpd -l 20:mpshost:1000 -p 1
Specifies one request per connection. Messages may be sent without IDs.
