Abstract:
PURPOSE: A system and a method for offering a multiple participants quiz application service through the network using an Open API(Application Programming Interface) are provided to advance a quiz by a progress of a quizmaster, and make the participants share knowledge information through viewing by allowing multiple viewers. CONSTITUTION: An Open API part(300) certifies connections from a participant terminal and a viewer terminal, and transfers a connection approval message and an access level to both terminals by forming a multi-party call session between terminals after certification. A storing part(320) stores quiz problems of a voice and/or text type. Personal information managers(330,340) respectively manage participant information and viewer information. A quiz advancing part(350) reads/transmits the quiz problem stored in the storing part to the participant/viewer terminals, assigns a voice based on a time receiving a voice request signal received from the participant/viewer terminals, and accumulates quiz points corresponding to the participant/viewer terminal receiving the voice depending on right/wrong of a received answer.
Abstract:
PURPOSE: A routing/wavelength assignment method in consideration of influence on potential connection request in DWDM(Dense Wavelength Division Multiplex) network, and a differentiated routing/wavelength assignment method using connection request and a system thereof are provided to quantitatively evaluate a degree of an influence on a connection request, and to determine the least influenced path, thereby reducing a blocking probability of the connection request. CONSTITUTION: If a connection request is received in an edge node(200), a service classifier checks a type of a service(205). In a routing system aspect, a routing process is conducted by values of each link wavelength SNR(210,220). If the type of the service is an assured service, a system shares a backup path to perform a protection function so as to efficiently use resources(225). If the routing process is conducted by a premium service and the assured service, the system assigns wavelengths in an FF(First-Fit) method(240). If the number of the wavelengths is smaller than that of nodes(235) or the wavelengths are not included, the connection request is blocked(255).
Abstract:
PURPOSE: A system for providing a multi-cast communication service and a control method thereof are provided to make a different kind terminal of a receiving party coexist within one multi-cast tree through a user specialization function of a multi-cast application, and to enable dynamical combination/separation with the multi-cast tree according to user's intension. And the system is provided to be virtually configured inside a memory of a routing performing unit, so that efficient path setup can be enabled and a transceiving bandwidth can be reduced. CONSTITUTION: A network monitoring unit(14) collects link state information of a communication network, and detects state information of every exchange. A group managing unit(15) manages the configuration of multi-cast service users and receives a request for generating a multi-cast tree, to inform an information provider(11) of addresses of group members. And the group managing unit(15) supplies a negotiation channel between the information provider(11) and an information user(12), and delivers information on group members, requests according to users, and a user specification program. A routing performing unit(16) receives information on a communication network state of the network monitoring unit(14), and information on the information provider(11) and the information user(12) of the group managing unit(15) to calculate the multi-cast tree connecting end-to-end. And the routing performing unit(16) converts the calculate logical multi-cast tree into information to be delivered to the exchanges. A connection managing unit(17) transmits the routing information of the routing performing unit(16) to each exchange, to set up a multi-cast path through signal transfer between the exchanges.
Abstract:
PURPOSE: A method for setting up a path of multi-connecting multi-layer switch is provided to simplify the configuration of the hardware by adjusting the switching path with parallel shuffle network comprising the function of a switching element in achieving the parallel shuffle network based multi-connected multi-layer switch. CONSTITUTION: The address of the input/output node of a multi-layer switch is acquired by reading a virtual path identification and a virtual connection identification(301). The point value P necessary for routing is acquired and recorded in the tag(302). The point value P is read in the path tag(303). It is judged whether the point value P is "0"(304). If the point value P is not "0", it is judged whether the point value P is more than alpha(305). If the point value P is "0", the switching element transmits the associated cell to the external and finalizes the path setup(306). If the point value P is more than alpha, the switching element reduces a point value(307), and transmits the reduced point value to a desired switching element(308). If the point value P is alpha or less, the switching element transmits the cell to the associated output terminal(309). The switching element judges whether three cells will be outputted to a specific output terminal at the same time(310). The switching element judges whether the presently outputted cell is the second one if three cells are about to be outputted to a specific output terminal at the same time(311). If it is the second cell, the switching element transfers the second cell to the identical switching element of sub layer shuffle network(312), and judges whether the sub layer is last one(313). If the sub layer is last one, the path setup is completed(314).
