Abstract
Abstract A system and method for connecting subarea SNA (systems network architecture) peripheral nodes into an APPN (Advanced Peer-to-Peer Network) network such that the peripheral nodes can function in the APPN network without upgrades to their existing software. This method also also enhances the manageability of the peripheral nodes by allowing the representation of the PU (physical unit) to reside in the peripheral node.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
99 words
A computer telecommunications network system having at least one APPN host in at least one APPN network connecting to at least one sub-area SNA peripheral node through an SNA gateway, said telecommunications network comprising: means for connecting said at least one sub-area SNA peripheral node through said SNA gateway using APPN DLUR; means at said gateway for translating an address representing said peripheral node between an APPN address and a subarea address such that said peripheral node can receive first information from said APPN network; and means at said host for receiving second information from the gateway using DLUS.
Claim 2
Dependent Claim
99 words
A computer telecommunications network system having at least one APPN host in at least one APPN network connecting to at least one sub-area SNA peripheral node through an SNA gateway, said telecommunications network comprising: means for connecting said at least one sub-area SNA peripheral node through said SNA gateway using APPN DLUR; means at said gateway for translating an address representing said peripheral node between an APPN address and a subarea address such that said peripheral node can receive first information from said APPN network; and means at said host for receiving second information from the gateway using DLUS.
Claim 3
Independent Claim
110 words
A method for attaching one or more unmodified sub-area SNA peripheral nodes to one or more APPN networks by way of an SNA gateway, said method comprising the steps of: defining a DLUS node in a host computer connected to one of said APPN networks; defining a DLUR node in the SNA gateway; establishing a DLUS/DLUR session between said host computer connected to one of said APPN networks and said SNA gateway; establishing an SSCP -- LU session between the gateway and one of said peripheral nodes; and transforming information transmitted from the sub-area SNA peripheral node to the APPN network by translating address information in the information being transmitted.
Claim 4
Independent Claim
110 words
A method for attaching one or more unmodified sub-area SNA peripheral nodes to one or more APPN networks by way of an SNA gateway, said method comprising the steps of: defining a DLUS node in a host computer connected to one of said APPN networks; defining a DLUR node in the SNA gateway; establishing a DLUS/DLUR session between said host computer connected to one of said APPN networks and said SNA gateway; establishing an SSCP -- LU session between the gateway and one of said peripheral nodes; and transforming information transmitted from the sub-area SNA peripheral node to the APPN network by translating address information in the information being transmitted.
Claim 5
Dependent Claim
24 words
The method as in claim 2 further comprising the step of: establishing an SSCP -- PU session between the gateway and the peripheral node.
