(ZH) 流量调度
(EN) Provided are a traffic scheduling method, a service orchestrator (SO) and a machine-readable storage medium. In the embodiments, the method comprises: the SO acquiring load information about each BRAS of a plurality of remote access servers (BRAS); receiving an access initiating packet, from a client, sent by an OpenFlow switch; according to the acquired load information, selecting a target BRAS with the minimum load from the plurality of the BRASs, and determining a MAC address of the target BRAS and an identifier of a target port identifier, on the OpenFlow switch, connected to the target BRAS; and sending the MAC address of the target BRAS and the target port identifier to the OpenFlow switch, so that the OpenFlow switch sends the access initiating packet to the target BRAS via the target port.
(FR) L'invention concerne un procédé de programmation de trafic, un orchestrateur de service (SO), et un support de stockage lisible par machine. Dans le procédé décrit dans les modes de réalisation de l’invention, le SO : acquiert des informations de charge relatives à chaque serveur d'accès à distance (BRAS) d'une pluralité de BRAS ; reçoit, d'un client, un paquet d'initiation d'accès envoyé par un commutateur OpenFlow ; d’après les informations de charge acquises, sélectionne un BRAS cible avec la charge minimale parmi la pluralité de BRAS, et détermine une adresse MAC du BRAS cible et un identificateur d'un identificateur de port cible, sur le commutateur OpenFlow, connecté au BRAS cible ; et envoie l'adresse MAC du BRAS cible et l'identificateur de port cible au commutateur OpenFlow, de sorte que le commutateur OpenFlow envoie le paquet d'initiation d'accès au BRAS cible via le port cible.
(ZH) 本申请提供流量调度方法、业务编排器SO及机器可读存储介质,在实施例中,该SO获取多个远程接入服务器BRAS中的每一个BRAS的负载信息;接收到开放流OpenFlow交换机发送的来自客户端的接入发起报文;根据获取的负载信息,从所述多个BRAS中选择负载最小的目标BRAS,并确定所述目标BRAS的MAC地址、以及所述OpenFlow交换机上连接所述目标BRAS的目标端口标识;将目标BRAS的MAC地址和目标端口标识发送给所述OpenFlow交换机,以使所述OpenFlow交换机将所述接入发起报通过所述目标端口发送给所述目标BRAS。
