Abstract

Disclosed is a procedure that allows a user on a LAN workstation to receive a program from another workstation and execute it on the local machine. The name of this procedure is the Alternate Work Station Emulation Procedure (AWSEP).

Alternate Work Station Emulation Procedure

      Disclosed is a procedure that allows a user on a LAN
workstation to receive a program from another workstation and execute
it on the local machine.  The name of this procedure is the Alternate
Work Station Emulation Procedure (AWSEP).

      There is a need to access executable programs by a LAN
workstation from another LAN workstation without the overhead and
expenses of installing large communication programs such as TCP/IP
session emulation.  This is especially needed where low cost
workstations with little to no hard drive storage exist, nor LAN
server or shared disk partitions are defined.

      AWSEP utilizes a simplified set of protocols and data formats
to locate and "cross-load" executables among workstations on a LAN.
A simple LAN protocol such as NETBIOS can be used to transfer the
command and data defined by this procedure.  When a user requires a
program that is not on the local workstation, the AWSEP procedure
generates a global query, transporting the name of the program
required, which is received by each workstation on the LAN.  For each
workstation that has the program, a response is returned.  When the
first response is received by the requesting workstation, another
request is sent to that workstation requesting the executables that
comprise that program.

      The AWSEP procedure provides a full-screen utility function
evoked by the user when a program, not present on the local
workstation, is required.  The user indicates the name of the program
and can select whether a global LAN query for that program be
generated or specific workstations can be checked.  When the program
name is specified and the type of search is indicated, the utility
passes this information to the AWSEP Requester component.  This
component generates a query data packet and is sent to the
user-specified workstations in order to locate the program.  The
format of this packet follows:
  FuncType      ProgramName      RequesterID

      FuncType is the type of request (i.e., query), ProgramName
indicates the name of the executable for which the search is
occurring, and RequesterID is the name of the requesting workstation.
When the query data packet is received by the targeted workstations,
each workstation searches for the program.  If found, then a response
is generated indicating the presence of the program.  The RequesterID
name can be used to provide a level of security by the receiver.  If
the receiving workstation determines that the requester should not...
