Abstract: 문자열 매칭 장치는 입력되는 데이터 스트림으로부터 시작위치를 하나씩 이동시키면서 문자열을 추출하고, 추출된 문자열을 타겟 문자열에 포함된 서브 문자열과 비교한다. 또한, 입력되는 데이터 스트림으로부터 추출된 문자열로부터 타겟 문자열의 프리픽스가 검출되면 해당 문자열의 시작위치를 토대로 다음 스테이지에 출력되는 문자열 중에서 하나만을 선택하여 서브 문자열 검출에 이용한다.
또한, 상태 천이 프로세스를 이용하여 하나 이상의 타겟 문자열을 입력 데이터 스트림으로부터 연속적으로 검출할 수도 있다.

Abstract: PURPOSE: A random backoff apparatus for an augmented content reception and a method thereof are provided to enable multiple viewers to efficiently use a bi-directional service by preventing multiple reception terminals from being connected to a program-related website or augmented content at the same time. CONSTITUTION: A reception terminal (510) receives meta data from a server (520).

Abstract: An apparatus and a method for managing traffic by using a VID(VLAN(Virtual LAN) Identification) in an EPON(Ethernet Passive Optical Network) are provided to allow a general commercialized switch or router to smoothly perform traffic management for numerous subscribers and subscriber services. A MAC lookup table(15) matches VIDs to be used within an EPON by MAC address and managing them. A service classification policy table(20) stores service classification references corresponding to service control parameters of each VID. A service control policy table(25) stores service policies to be provided according to each classified service. When a downlink packet is inputted, a MAC look-up module(30) looks up a VID corresponding to a MAC address of the corresponding downlink packet by referring to the MAC look-up table(15). The first service classifying module(35) classifies a VID service class of the downlink packet. The first service control module(40) provides a service of a downlink transmission flow according to the classified VID service class. A VID study module(50) studies VIDs through a packet frame of an uplink packet and updates the MAC look-up table(15). The second service classifying module(55) classifies a VID service class of the uplink packet. The second service control module(60) requests a service according to the classified VID service class in case of an uplink transmission flow.
