transaction: a transaction may be either an incoming message
or an outgoing message.
incoming message, type A:
an incoming message is by definition one destinated
for the ACDN Host Environment. The average length
of an incoming message as received by the ACDN network
is 34 characters. The internal length is determined
by adding the associated network header of 20 bytes,
i.e. to 54 bytes.
outgoing message, type B:
an outgoing message is by definition one originated
at the ACDN Host Environment.
The average length of an outgoing message as received
by the ACDN network is 234 characters. The internal
length is determined by adding the associated network
header of 20 bytes, i.e. to 254 bytes.
message, type B:
a type B message is one which is subject to PMS.
It may be originated at, and destinated for by any
of the environments ecternal to the network. The
average length of an type B message, whether incoming
or outgoing, is 348 characters. The internal length
is determined by adding the associated network header
of 20 bytes, i.e. to 368 bytes.
node systems: the CR80 SCP and NSP complex at any of the three
locations: Toronto, Montreal and Winnipeg. All
includes the software packages SCS, NSS, TAS
and HAS and as required ENAS and INAS.
user: travel agent
operator: EMH/NMH
supervisor: NCC operator (AC network monitors)
