摘要:
An optical network has: sections for establishing optical paths; a plurality of optical edge routers for connecting external IP networks to the optical network (1001); and a plurality of optical cross connects, for connecting the optical edge routers by the optical paths, having switching sections with respect to an optical pulse unit. In the optical network, each of the optical edge routers has both of: (1) an optical network control instance (INSp) for maintaining topology information in the optical network and switching/signaling the optical paths; and (2) an IP network instance (INSi) for maintaining a routing table in each of the external IP networks and activating routing protocols between the external IP networks and the IP network instance. By doing this, it is possible to realize a multi-layer cooperative function and provide highly safe optical networks, etc.

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:
A plurality of pieces of information about a link (hereinafter referred to as “link information”), which are stored in a common DB, are categorized in accordance with the VPN related to each piece of link information. VPNID, which is information for identifying each VPN, is added to each piece of link information which has been categorized. 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:
An information processing apparatus and method configured to display content in a content display screen area, which is at least one of a plurality of screen areas, displayed. The information processing apparatus includes an event detector configured to detect generation of a predetermined event concerning a content, a notifying unit configured to notify a user of the information processing apparatus of the detection of the predetermined event upon detecting the predetermined event, a work concentration state detector configured to determine whether the user is in a work concentration state, and an inhibiting unit configured to inhibit the notifying unit from notifying the user of the detection of the predetermined event upon determining the work concentration state of the user.
摘要:
There is provided a preference data generation device for generating preference data of a viewer pertinent to content to be displayed in a content display screen area that is one of a plurality of screen areas displayed on a display unit in an information processing system apparatus provided with the display unit, the device including a state information acquisition unit that acquires state information pertinent to the plurality of screen areas displayed on the display unit; a preference evaluation value calculation unit that calculates a preference evaluation value pertinent to the content, based on the state information acquired by the state information acquisition unit; and a preference data generation unit that generates preference data pertinent to the content, based on the preference evaluation value calculated by the preference evaluation value calculation unit.
