Abstract:
복수의 분산 클라이언트들간의 영상 회의를 위하여, 분산 제어부가 제1 분산 클라이언트로부터 주화자로 선택된 제2 분산 클라이언트에 대한 패킷 요청을 수신하고, 분산 제어부의 요청에 따라 분산 미디어 처리부가 제1 분산 클라이언트와 상기 제2 분산 클라이언트에 대한 패킷 스위칭을 위한 스위칭 엔트리를 생성한다. 분산 제어부가 상기 제2 분산 클라이언트로 패킷 송신을 요청하며, 분산 미디어 처리부가 제2 분산 클라이언트로부터 수신된 패킷을 스위칭 엔트리를 토대로 제1 분산 클라이언트로 송신한다.
Abstract:
PURPOSE: An application service based service quality providing method is provided to offer an application service based QoS(Quality of Service) for user traffic in a router including a classification function. CONSTITUTION: When the packet of user traffic is inputted to a packet interface(S602), a packet capturing unit captures the packet and transmits the packet to a packet analysis unit. The packet analysis unit inspects an application service and the fifth-tuple information of the packet by analyzing the IP(Internet Protocol) header information and the inner payload of the packet. When a service flow session corresponding to the fifth tuple information of the packet is not existed, a flow session management unit confirms the existence of QoS information according to the application service of the corresponding packet. [Reference numerals] (AA,DD) Yes; (BB,CC) No; (S602) Receive a packet; (S604) Inspect fifth-tuple information and application service of the packet; (S606) Is there a service flow session?; (S608) Is there QoS information to be applied to the application service of the packet?; (S610) Generate the service flow session; (S612) Transmit the fifth-tuple information and QoS information of the packet; (S614) Scrap the packet
Abstract:
PURPOSE: A virtual tunnel router and an IP camera managing server are provided to configure a direct communication environment based on a virtual IP between a user terminal and an IP camera. CONSTITUTION: A connection setting unit(110) sets up an IP(Internet Protocol)-UDP(User Datagram Protocol)-TCP(Tape Carrier Package)-IP tunnel and the other virtual tunnel router. A direct communication environment configuring unit(120) switches virtual network prefix information with the other virtual tunnel router. The direct communication environment configuring unit configures a direct communication environment and an IP camera.
Abstract:
A router advertisement managing method in a distributed router and an apparatus thereof are provided to manage each router advertisement setup table according to input interfaces of each line card in order to implement a router advertisement function, without the necessity of identically maintaining data through periodical communication with all line card network processors. An RA(Router Advertisement) management part initializes a router advertisement table with pre-defined default values. Also, the RA management part initializes a process for receiving a command event from an operator(400). If a command is received from the operator, the RA management part checks the validity of each parameter value with respect to one or more parameters contained in the command(410). If it is confirmed that all the parameter values are valid, the RA management part stores an interface name in the router advertisement table as an index(420). Then, the RA router creates a router advertisement packet according to contents stored in the router advertisement table, and then transmits it to an associated host system(430).

Abstract:
A system to provide a video conference service is provided. The system includes: a multipoint processor configured to process media occurring during a video conference so as to allow the processed media to be transmitted and received between the user terminals; and one or more multipoint controllers configured to control a session of a user terminal participating in a multi-participant video conference, wherein the multipoint processor and the multipoint controllers are separate from each other.
