Abstract: front page image
(EN)Disclosed are a packet output controlling method and a network device using the same. A packet output controlling method according to the present invention, as a method for processing flow in a plurality (N, where N is a natural number of 2 or greater) of flow tables connected by a pipeline, may comprise the steps of: passing a packet input into a flow from a first table to an N-1st table from among a plurality of tables; processing an output-dedicated Nth table (egress table) guided by the N-1st table with respect to the packet after the packet passes the N-1st table; and outputting the packet after processing the Nth table. Accordingly, the flexible control of a final output is made possible through various operations using output port information.
(FR)L'invention concerne un procédé de commande de sortie de paquets et un dispositif réseau utilisant ledit procédé. Un procédé de commande de sortie de paquets selon la présente invention, en tant que procédé de traitement de flux dans plusieurs (N, N étant un entier naturel supérieur ou égal à 2) tables de flux connectées par un pipeline, peut comprendre les étapes consistant : à passer une entrée de paquet dans un flux depuis une première table vers une N-1-ième table parmi plusieurs tables ; à traiter une N-ième table dédiée à la sortie (table de sortie) guidée par la N-1-ième table en ce qui concerne le paquet après le passage du paquet par la N-1-ième table ; et à sortir le paquet après le traitement de la N-ième table. Par conséquent, la commande souple d'une sortie finale est rendue possible grâce à diverses opérations utilisant les informations de port de sortie.
(KO)패킷 출력 제어 방법 및 이를 이용한 네트워크 장치가 개시된다. 본 발명에 따른 패킷 출력 제어 방법은 파이프라인으로 연결된 복수 개(N개; N은 2이상의 자연수)의 플로우 테이블에서 플로우 처리 방법에 있어서, 플로우의 유입된 패킷이 복수 개의 테이블 중, 제1 테이블부터 제N-1번 테이블을 경유하는 단계, 패킷이 N-1번째 테이블을 경유한 이후에, 패킷에 대해 N-1번째 테이블에 의해 지시되는 출력 전용 N번째 테이블(egress table)의 처리를 수행하는 단계 및 N번째 테이블의 처리 이후에 상기 패킷을 출력하는 단계를 포함하여 구성될 수 있다. 따라서, 출력 포트 정보를 이용한 다양한 동작을 통해 최종 출력을 유연한 제어가 가능하다.
