User Assigned Host Agent

      A mechanism is described which provides optimal gateway
administration and processing when system constraints restrict a
system to allow user access to one gateway at any particular time.

      In the absence of a true node-to-node implementation, as
offered by SNA/DS or the like, gateway functionality is often
achieved through delegated user control. A host agent, which is a
software process dedicated to providing a gateway service,
programmatically logs on to a host system to upload and download
distributions and status. The host agent has a logon user identifier
(id) to the host. The logon user id has delegated rights assigned to
send and receive distributions and status on behalf of a set of
users, namely the users which require gateway access. Delegation
rights are assigned through normal host user administration. The side
effect of this gateway scheme is a user can only access one gateway
at any instant in time because the user is defined on the connected
host system. It does not make sense to have the same user id
(NODEID.USERID) on more than one system, especially when the systems
become connected. Thus, a best gateway design is needed to fit an
environment where a user can access one gateway at any given time.

      The present invention implements source address assigned host
agents. This allows distributions addressed to an infinite number of
node identifiers (NODEIDs) to leave the originating server, bound for
a gatew...
