摘要:
A first apparatus receives, at a first transmission rate, packets belonging to a target packet flow on which packet-shaping processing for controlling network traffic is to be performed, and stores the received packets in a first packet buffer. Then, the first apparatus performs first packet-shaping processing on the target packet flow by transmitting, at a second transmission rate, packets that belong to the target packet flow and read out from the first packet buffer. A second apparatus stores packets received from the first apparatus in a second packet buffer. When a shortage of buffer resource for storing packets belonging to the target packet flow occurs in the first packet buffer, the second apparatus performs second packet-shaping processing on the target packet flow by transmitting, at a third transmission rate, packets that belong to the target packet flow and are read out from the second packet buffer.

In the case of providing a variable data print, it is an object to provide an image processing apparatus in which the user can take a countermeasure against an error more rapidly. When a variable data printing process is started, whether or not image data is inaccessible is discriminated to all image data used in the printing process. If there is the inaccessible image data at this point of time, the user is notified of it and the printing process is cancelled. At this time, a path name of the image data and a name of a record to which the path name belongs are simultaneously displayed and such a record is directly previewed.

A communication device of the present invention performs communication over a network where a session is identified based on a source address set in a frame. The communication device comprises an interface unit for connecting to the network, a management unit for managing a plurality of addresses, a request unit for transmitting a frame including a session establishment request to an authenticator system provided on the network through said interface unit, and an address setting unit for setting one of the plurality of addresses managed by said management unit as a source address of the frame including the session establishment request.

In an MPLS network, multicast, broadcast and address learning belonging to the layer 2 functions are realized. An ingress router comprises a frame receiving unit, a determining unit, a first frame transmitting unit, a physical address table for multicast, a label switching unit, a tunnel label table, a VCID giving unit, a L2 header creating unit and a second frame transmitting unit. The load on the network is suppressed, the band is efficiently used, and wasteful frame duplication and frame forwarding between edge routers are avoided.

A packet transmission device includes a buffer stores packet data in any of queues, a queue manager outputs queue-status signals indicating whether or not transmittable packet data exists in the corresponding one of the queues, a bandwidth controller outputs token-status signals indicating whether or not an amount of the tokens accumulated at a certain period for the corresponding queue is larger than a token threshold provided for the corresponding queue, a queue selector preferentially selects any queue whose duration time of a transmittable state in which the corresponding queue status signal indicates that transmittable packet data exists in the corresponding queue and the corresponding token-status signal indicates that the amount of the accumulated tokens is larger than the token threshold provided for the corresponding queue is greater than a duration-time threshold provided for the corresponding queue, and a buffer reader controls reading of the packet data from the selected queue.

A first apparatus receives, at a first transmission rate, packets belonging to a target packet flow on which packet-shaping processing for controlling network traffic is to be performed, and stores the received packets in a first packet buffer. Then, the first apparatus performs first packet-shaping processing on the target packet flow by transmitting, at a second transmission rate, packets that belong to the target packet flow and read out from the first packet buffer. A second apparatus stores packets received from the first apparatus in a second packet buffer. When a shortage of buffer resource for storing packets belonging to the target packet flow occurs in the first packet buffer, the second apparatus performs second packet-shaping processing on the target packet flow by transmitting, at a third transmission rate, packets that belong to the target packet flow and are read out from the second packet buffer.

An IP application service providing method enabling inbound communication in IP application communication intended between an internal node concealed from an outside network and belonging to an inside network and an external node belonging to the outside network through a gateway device set to permit only outbound communication, includes periodically transmitting a control packet aiming at notifying of a control channel port and at maintaining a communication permission entry of a control channel path to a connection support device on the outside network from the internal node subordinated to the gateway device; notifying the internal node of a connecting destination address/port pair associated with the external node via the control channel from the connection support device; and actively opening a data channel of an IP application to the notified connecting destination address/port pair.

A user may have trouble selecting a desired design when too many generated designs are displayed on a list. There is also a problem that the user cannot easily create a derived design if the user has little design knowledge when the user needs the derived design based on the desired design among the generated designs.Included are: a memory unit that stores a template of a basic design corresponding to a combination of a character and an image and a template of a derived design associated with the basic design; and a generating unit that applies the entered character or image to the template of the basic design read from the memory unit to generate a basic design and display the basic design on a display unit, reads the template of the derived design associated with the basic design selected, based on the operation by the user, from the memory unit, and applies the character or image used to generate the basic design to generate the derived design and display the derived design on the display unit.
