Abstract

This article addresses the need to remove a performance inhibitor between OfficeVision* Servers. It is the requirement for Gateways when Servers speak different communication protocols. The requirement for Gateways between Servers in OfficeVision is a performance inhibitor. A Gateway is a Server itself that speaks two communication protocols. When one Server wishes to send a transmission to another Server that speaks a different communication protocol, it must use a Gateway to handle the communication differences. Examples of this are X.400 Gateways between the X.400 network and DISOSS in MVS or the OfficeVision/VM* (OV/VM) Mailman in VM, and Bridges between PROFS* and DISOSS and between PROFS and AS/400*. Other examples are Gateways between OfficeVision (OV) LAN products and OV/VM.

Reduction of Gateways by OfficeVision Servers

       This article addresses the need to remove a performance
inhibitor between OfficeVision* Servers.  It is the requirement for
Gateways when Servers speak different communication protocols.  The
requirement for Gateways between Servers in OfficeVision is a
performance inhibitor. A Gateway is a Server itself that speaks two
communication protocols.  When one Server wishes to send a
transmission to another Server that speaks a different communication
protocol, it must use a Gateway to handle the communication
differences.  Examples of this are X.400 Gateways between the X.400
network and DISOSS in MVS or the OfficeVision/VM* (OV/VM) Mailman in
VM, and Bridges between PROFS* and DISOSS and between PROFS and
AS/400*.  Other examples are Gateways between OfficeVision (OV) LAN
products and OV/VM.  The transmission is sent to the Gateway or
Bridge, where it is converted to the communication protocol of the
target Server.  It is then sent on to the target Server, so that it
appears that the transmission is coming from a peer Server. In
addition to adding to transmission time, the cost of a Gateway is the
conversion of the addressing information between protocols.  For
return of the transmission the information of the original protocol
must be kept hidden so that it can be used again by the Gateway.

      The solution is to provide multiple protocol handlers within
the OfficeVision Server.  Rather than continuing to require Gateways,
we must improve the Server to meet...
