* connect.h
*
* Copyright (c) 1993 - 1995 by DataBeam Corporation, Lexington, KY
*
* Abstract:
* This is the interface file for the Connection class. Instances of
* this class are used to connect CommandTarget objects within the local
* provider to CommandTarget objects in a remote provider. This class
* inherits from CommandTarget, allowing it to communicate with other
* CommandTarget classes using their common MCS command language.
*
* This class can be thought of as providing a Remote Procedure Call (RPC)
* facility between CommandTarget objects. When an MCS command is sent
* to a Connection object, it encodes the command as a T.125 Protocol
* Data Unit (PDU) and sends it to a remote provider via the transport
* services provided by a TransportInterface object. At the remote side
* The PDU is received by a Connection object who decodes the PDU, and
* issues the equivalent MCS command to the CommandTarget object that it is
* attached to. The fact that the call crossed a transport connection
* in route to its destination is completely transparent to the object
* that initiated the command sequence.
*
* The primary responsibility of this class is to convert MCS commands
* to T.125 PDUs and back again (as described above). This class overrides
* all of the commands that are defined in class CommandTarget.
*
* A secondary responsibility of this class is to provide flow control
* to and from the transport layer. To do this is keeps a queue of PDUs
* that need to be transmitted (actually it keeps 4 queues, one for each
* data priority). During each MCS heartbeat, all Connection objects are
* given the opportunity to flush PDUs from the queues. If the transport
* layer returns an error, the PDU in question will be re-tried during
* the next heartbeat. For data coming from the transport layer, this
* class provides code to allocate memory. If an allocation fails, then
* an error will be returned to the transport layer, effectively telling
* it that it needs to retry that data indication during the next
* heartbeat.
*
* Caveats:
* None.
*
* Author:
* James P. Galvin, Jr.

* - If this MCS connection is not yet bound to a domain, then the request
* is not valid.
* - If there are not enough objects of the Memory, Packet, or UserMessage
* class to handle a reasonable request, then the request is not valid.
*
* Note that the check on number of objects is not an absolute guarantee
* that there will be enough to handle a given request, because a request
* can result in MANY PDUs and user messages being generated. For example,
* a single channel admit request can result in lots of channel admit
* indications being sent. However, checking against a minimum number
* of objects can reduce the possibility of failure to be astronomically
* low. And remember, even if MCS runs out of something while processing
* such a request, it WILL handle it properly (by cleanly destroying the
* user attachment or MCS connection upon which the failure occurred). So
* there is no chance of MCS crashing as a result of this.
