摘要： A route switching method for switching a route in a core network that accommodates service networks including user node apparatuses by use of a server storing path information that includes, in every time frame, a route for a working path and a route for a backup path to be switched over from the working path, both of the working path and the backup path established between two boundary node apparatuses each of which is located on a boundary between the service network and the core network. The server calculates, in response to the connection request from the user node apparatus, a route for a working path and a route for a backup path, and requests the boundary node apparatus to establish this working path. The server can send the route for the backup path to the boundary node apparatus before a failure occurs in the core network. The boundary node apparatus establishes the working path in response to the establishment request for establishing the working path from the server, and can perform a quick recovery by switching over the working path to the backup path when a failure occurs in the core network.

摘要： The path management controller 1 refers to resource information 131 including reservation statuses of working paths and advance reserved paths that are set in every link, so as to calculate a route for setting a new path and set this path in this calculated route. If the route for setting this new path cannot be obtained (1) because of a shortage of residual bandwidth of a link of interest, the path management controller 1 refers to the resource reservation information 131 of working paths and advance reserved paths and calculates an alternative route for another existing path used in the link of interest, and moves this path to the calculated alternative route. On the other hand, if the route for setting this new path cannot be obtained (2) because there is no continuous bandwidth sufficient for setting this new path in the link of interest, the path management controller 1 refers to the resource reservation information regarding working paths and advance reserved paths in the link of interest in the resource information 131, so as to execute the time slot rearrangement.

摘要： VPNID which is an information for identifying each of VPN is added to each link information which is formed by categorizing a link information in a common DB for each VPN to which the link information relates. The link information for the same VPNID is extracted from the link information to which the VPNID for the common DB is added so as to be contained in the corresponding VPNDB. By doing this, it is possible to realize a path design for the customer easily by providing the network information in the VPN provider and the network information of the customer network while realizing a high scalability.

摘要： The present invention is directed to a “negative lead type” zoom lens advantageous for downsizing the entire lens system, which has a high zoom ratio and provides superior compensation for aberration, retaining a predetermined back focal distance. The zoom lens has at least a first or leading lens unit of negative refractive power and a second or succeeding lens unit of positive refractive power in this order from the view point closer to a photographed object. The first lens unit is of two positive lens pieces and three negative lens pieces while the second lens unit provides an aspherical surface, having a positive lens piece in the second foremost position closer to a photographed object. During the zooming from a wide-angle view to a tele-photo view, a separation between the first and second lens unit is reduced. The first lens unit serves as a focusing lens, and the zoom lens satisfies requirements as expressed in the formulae 3.0

摘要： The present invention is directed to an inner focusing macro lens that has a large aperture ratio as expressed by 2.5 or even smaller in F-number and still remains compact, and that is adapted to compensate for spherical aberration, astigmatism, and comatic aberration during photographing throughout the entire object distance ranging from infinity to proximity for an up to 1:1-magnification image. The inner focusing macro lens has the leading or first lens group of positive refractivity, the second lens group of negative refractivity, the third lens group of positive refractivity, and the trailing lens set succeeding to the third lens group in sequence from a position closest to an object being photographed. During focusing from a point infinitely far to that as proximal as desired, the first lens group is static while the second lens group is moved toward the imaging plane, and the third lens group is moved toward the object. The first lens group has at least four lens pieces of comprehensively positive refractivity and at least one lens piece of negative refractivity, and three of the lens pieces closest to the object in the first lens group are of positive refractivity.
