unit 21 that, when a new communication path is set in a communication network in which predetermined communication paths constituted by an active path and a redundant path are set, allocates a network capacity to the active path constituting the new communication path in such a manner that a network capacity reserved for the redundant path is shared by the active path constituting the new communication path and by the redundant path. ## Claims ### Claim 1 A communication path setting apparatus, comprising an allocation unit which, when a new communication path is set in a communication network in which predetermined communication paths constituted by an active path and a redundant path are set, allocates a network capacity to an active path constituting the new communication path in such a manner that a network capacity reserved for the redundant path is shared by the active path constituting the new communication path and by the redundant path. ### Claim 2 (depends on 1) The communication path setting apparatus according to claim 1, wherein the allocation unit allocates, to a redundant path constituting the new communication path, network capacity reserved for the redundant path constituting the predetermined communication path so that the redundant path constituting the new communication path and the redundant path constituting the predetermined communication path share the network capacity. ### Claim 3 (depends on 1) The communication path setting apparatus according to claim 1, wherein the allocation unit allocates, to the active path constituting the new communication path or a redundant path constituting the new communication path, network capacity that is determined to satisfy a predetermined condition. ### Claim 4 (depends on 1) The communication path setting apparatus according to claim 1, wherein the allocation unit allocates, to the active path constituting the new communication path or a redundant path constituting the new communication path, network capacity so that a time taken for switching a path to be used as a communication path from an active path to a redundant path when a failure occurs in the communication network is within a predetermined time. ### Claim 5 (depends on 1) The communication path setting apparatus according to claim 1, comprising a storage unit which stores communication path information which is information relating to a communication path set in the communication network, wherein the communication path information includes information of network capacity allocated to the communication path. ### Claim 6 (depends on 5) The communication path setting apparatus according to claim 5, wherein information of network capacity allocated to a plurality of communication paths includes information indicating a relationship between the plurality of communication paths. ### Claim 7 A communication path setting method, comprising when a new communication path is set in a communication network in which predetermined communication paths constituted by an active path and a redundant path are set, allocating a network capacity to an active path constituting the new communication path in such a manner that a network capacity reserved for the redundant path is shared by the active path constituting the new communication path and by the redundant path. ### Claim 8 (depends on 7) The communication path setting method according to claim 7, comprising allocating, to a redundant path constituting the new communication path, network capacity reserved for the redundant path constituting the predetermined communication path so that the redundant path constituting the new communication path and the redundant path constituting the predetermined communication path share the network capacity. ### Claim 9 A non-transitory computer-readable recording medium having recorded therein a communication path setting program for causing a computer to execute an allocation process of, when a new communication path is set in a communication network in which predetermined communication paths constituted by an active path and a redundant path are set, allocates a network capacity to an active path constituting the new communication path in such a manner that a network capacity reserved for the redundant path is shared by the active path constituting the new communication path and by the redundant path. ### Claim 10 (depends on 9) The medium according to claim 9, causing the computer to execute an allocation process of allocating, to a redundant path constituting the new communication path, network capacity reserved for the redundant path constituting the predetermined communication path so that the redundant path constituting the new communication path and the redundant path constituting the predetermined communication path share the network capacity. ### Claim 11 (depends on 2) The communication path setting apparatus according to claim 2, wherein the allocation unit allocates, to the active path constituting the new communication path or a redundant path constituting the new communication path, network capacity that is determined to satisfy a predetermined condition. ### Claim 12 (depends on 2) The communication path setting apparatus according to claim 2, wherein the allocation unit allocates, to the active path constituting the new communication path or a redundant path constituting the new communication path, network capacity so that a time taken for switching a path to be used as a communication path from an active path to a redundant path when a failure occurs in the communication network is within a predetermined time. ### Claim 13 (depends on 3) The communication path setting apparatus according to claim 3, wherein the allocation unit allocates, to the active path constituting the new communication path or a redundant path constituting the new communication path, network capacity so that a time taken for switching a path to be used as a communication path from an active path to a redundant path when a failure occurs in the communication network is within a predetermined time. ### Claim 14 (depends on 11) The communication path setting apparatus according to claim 11, wherein the allocation unit allocates, to the active path constituting the new communication path or a redundant path constituting the new communication path, network capacity so that a time taken for switching a path to be used as a communication path from an active path to a redundant path when a failure occurs in the communication network is within a predetermined time. ### Claim 15 (depends on 2) The communication path setting apparatus according to claim 2, comprising a storage unit which stores communication path information which is information relating to a communication path set in the communication network, wherein the communication path information includes information of network capacity allocated to the communication path. ### Claim 16 (depends on 3) The communication path setting apparatus according to claim 3, comprising a storage unit which stores communication path
