Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
170 words
A gateway apparatus for SNMP/OSI management enabling an SNMP manager to manage an OSI management agent comprising: SNMP protocol process means for giving and receiving a message by a simple network management protocol (SNMP) to/from the SNMP manager having the SNMP protocol as an interface, and for producing and analyzing a protocol data unit; OSI protocol process means for giving and receiving a message by a common management information protocol (CMIP) to/from the OSI management agent having the OSI protocol as an interface, and for producing and analyzing a protocol data unit; table means for determining a correspondence between a definition of OSI management information and a definition of SNMP management information; instance information means for keeping a name tree of the OSI management agent; conversion means for converting a management operation and the management information between the SNMP manager and the OSI management agent, said conversion means being connected with said SNMP protocol process means, said OSI protocol process means, said definition table means and said instance information means.
Claim 2
Dependent Claim
170 words
A gateway apparatus for SNMP/OSI management enabling an SNMP manager to manage an OSI management agent comprising: SNMP protocol process means for giving and receiving a message by a simple network management protocol (SNMP) to/from the SNMP manager having the SNMP protocol as an interface, and for producing and analyzing a protocol data unit; OSI protocol process means for giving and receiving a message by a common management information protocol (CMIP) to/from the OSI management agent having the OSI protocol as an interface, and for producing and analyzing a protocol data unit; table means for determining a correspondence between a definition of OSI management information and a definition of SNMP management information; instance information means for keeping a name tree of the OSI management agent; conversion means for converting a management operation and the management information between the SNMP manager and the OSI management agent, said conversion means being connected with said SNMP protocol process means, said OSI protocol process means, said definition table means and said instance information means.
Claim 3
Dependent Claim
35 words
The apparatus claimed in claim 1 further comprising: instance management means for renewing the name tree kept by said instance information means based on a result of the analysis by said OSI protocol process means.
Claim 4
Dependent Claim
83 words
The apparatus claimed in claim 1: said conversion means having cache means corresponding to every SNMP manager; when an attribute value is a structural type, said attribute value is kept in the cache means of said conversion means, and said attribute value is obtained by issuing a management operation of M-GETreq; when a request of the SNMP manager is to obtain a management information corresponding to the attribute value kept in the cache means, the attribute value in the cache means is transferred.
Claim 5
Dependent Claim
38 words
The apparatus claimed in claim 3: when the request of the SNMP manager is not to obtain a management information corresponding to the attribute value kept in the cache means, a content in the cache means is deleted.
Claim 6
Dependent Claim
27 words
The apparatus claimed in claim 3: when the request of the SNMP manager is to set a management information, a content in the cache means is deleted.
Claim 7
Dependent Claim
31 words
The apparatus claimed in claim 3: when an association between the OSI management agent and the gateway apparatus for SNMP/OSI management is disconnected, all contents in the cache means are deleted.
Claim 8
Dependent Claim
117 words
The apparatus claimed in claim 1: said conversion means having replica means; a copy of an attribute value is set in the replica means, wherein said attribute value is obtained by issuing a management operation of M-GETreq; when a request of the SNMP manager is to set a management information corresponding to the attribute value in the replica means, a management operation M-SETreq is issued for changing a value of the requested part and for setting it as a management information in the OSI management agent; when a request of the SNMP manager is to obtain a management information corresponding to the attribute value in the replica means, the attribute value in the replica means is transferred.
Claim 9
Dependent Claim
27 words
The attribute claimed in claim 7: said attribute value is copied according to a request, an existence of said request being stored in said definition table means.
Claim 10
Dependent Claim
31 words
The apparatus claimed in claim 7: when an association between the OSI management agent and the gateway apparatus for SNMP/OSI management is disconnected, all contents in the replica means are deleted.
Claim 11
Dependent Claim
31 words
The apparatus claimed in claim 7: plural copies being allowed in the replica means, wherein the oldest copy is deleted when a number of the copies is more than a maximum.
Claim 12
Dependent Claim
22 words
The apparatus claimed in claim 10: said oldest copy is periodically deleted by said conversion means based on expiration of a timer.
Claim 13
Dependent Claim
102 words
The apparatus claimed in claim 1: said conversion means having link object means; when a structural attribute of the management information of the OSI management agent is accessed, a structural data being generated as link object and said structural data being transferred as OPAQUE-type data to the SNMP manager, wherein said structural data represents a table structure which is converted and spread as a management information of SNMP from the structural attribute of the management information of OSI management and which includes a status of the table, index which can be used in the table, and a class structure of the table.
Claim 14
Dependent Claim
22 words
The apparatus claimed in claim 12: said link object means being independently set in every management object class of OSI management information.
Claim 15
Dependent Claim
33 words
The apparatus claimed in claim 1: said definition table includes an OPAQUE-type of SNMP management information item which is converted as SNMP management information definition from OSI management information definition by using OPAQUE-type.
Claim 16
Dependent Claim
44 words
The apparatus claimed in claim 14: an attribute type of the OSI management information being a structural type, wherein when a type is recursively defined in components included in said structural type, said attribute is an OPAQUE-type of a single SNMP management information item.
Claim 17
Dependent Claim
51 words
The apparatus claimed in claim 14: an attribute type of the OSI management information being a structural type, wherein a number of steps of a side table made by spreading the structural type is more than a predetermined number, said attribute is an OPAQUE-type of a single SNMP management information item.
Claim 18
Dependent Claim
31 words
The apparatus claimed in claim 1: said definition table means includes, as an SNMP management information item to be converted, an object representing a number of instances of OSI managed objects.
Claim 19
Dependent Claim
35 words
The apparatus claimed in claim 1: said definition table means includes, as an SNMP management information item to be converted, an object representing an existence of a conditional attribute in the OSI management information definition.
Claim 20
Dependent Claim
42 words
The apparatus claimed in claim 1: said definition table means includes, as an SNMP management information item to be converted, an object representing an existence of a optional component in an attribute of SEQUENCE-type or SET-type in the OSI management information definition.
Claim 21
Dependent Claim
40 words
The apparatus claimed in claim 1: said definition table means includes, as an SNMP management information item to be converted, an object representing a selection information of a component in an attribute of CHOICE-type in the OSI management information definition.
Claim 22
Dependent Claim
44 words
The apparatus claimed in claim 1: said definition table means includes, as an SNMP management information item to be converted, an object representing a repetition number of a component in an attribute of SEQUENCE OF-type or SET OF-type in the OSI management information definition.
