Abstract: front page image
(EN)A global server load balancer apparatus and a method for controlling time-to-live of a dynamic cache therein are disclosed. The global server load balancer apparatus, which performs load balancing between a plurality of local servers, according to an embodiment of the present invention, comprises: a DNS query processor for receiving a query message from a DNS server; a server selection unit for selecting any one local server from among the plurality of local servers when the query message is received; a load amount calculation unit for collecting state information of the global server load balancer apparatus and calculating a load amount of the global server load balancer apparatus from the collected state information; and a cache time-to-live controller for updating time-to-live (TTL) of the global server load balancer apparatus according to the calculated load amount.
(FR)L'invention concerne un appareil d'équilibrage global de charge entre serveurs et un procédé de régulation de durée de vie d'une antémémoire dynamique dans celui-ci. L'appareil d'équilibrage global de charge entre serveurs, qui effectue un équilibrage de charge entre une pluralité de serveurs locaux, comporte, selon un mode de réalisation de la présente invention: un processeur de requêtes DNS destiné à recevoir un message de requête en provenance d'un serveur DNS; une unité de sélection de serveurs destinée à sélectionner un serveur local quelconque parmi la pluralité de serveurs locaux lorsque le message de requête est reçu; une unité de calcul de quantité de charge destinée à recueillir des informations d'état de l'appareil d'équilibrage global de charge entre serveurs et à calculer une quantité de charge de l'appareil d'équilibrage global de charge entre serveurs à partir des informations d'état recueillies; et un contrôleur de durée de vie d'antémémoire destiné à actualiser une durée de vie (TTL) de l'appareil d'équilibrage global de charge entre serveurs en fonction de la quantité de charge calculée.
(KO)글로벌 서버 로드 밸런서 장치 및 상기 장치에서의 동적 캐쉬 유효 기간 제어 방법이 개시된다. 본 발명의 일 실시예에 따른 복수 개의 지역 서버 간의 로드 밸런싱을 수행하는 글로벌 서버 로드 밸런서 장치는, DNS 서버로부터 질의 메시지를 수신하는 DNS 질의 처리부; 상기 질의 메시지가 수신되는 경우, 상기 복수 개의 지역 서버 중 어느 하나의 지역 서버를 선택하는 서버 선택부; 상기 글로벌 서버 로드 밸런서 장치의 상태 정보를 수집하고, 수집된 상기 상태 정보로부터 상기 글로벌 서버 로드 밸런서 장치의 부하량을 계산하는 부하량 계산부; 및 계산된 상기 부하량에 따라 상기 글로벌 서버 로드 밸런서 장치의 TTL을 갱신하는 캐쉬 유효 기간 제어부를 포함한다.
