Abstract:
(EN) Disclosed in the present application are a method and device for switching paths, which are used to solve the problem wherein a direct routing path fails between a provider edge router (PE) and a customer edge device (CE), and downlink data cannot be forwarded on the PE, thereby causing an interruption in downlink traffic. The method for switching paths comprises: a first PE determining that a direct routing path between a CE changes from available to unavailable; the first PE issuing first routing information, which is used to enable the CE to receive data by means of a second PE, wherein the first PE and the second PE are both PEs accessed by the CE, and the first routing information comprises the routing overhead of the direct routing path between the first PE and the CE. The present application relates to the technical field of communications.
(FR) La présente invention concerne un procédé et un dispositif de commutation de chemins, qui sont utilisés pour résoudre le problème selon lequel un chemin de routage direct échoue entre un routeur côté fournisseur (PE) et un dispositif côté client (CE), et des données de liaison descendante ne peuvent pas être transmises sur le PE, ce qui provoque une interruption du trafic de liaison descendante. Le procédé de commutation de chemins comprend les étapes suivantes : un premier PE détermine qu'un chemin de routage direct entre un CE passe de disponible à indisponible ; le premier PE émet des premières informations de routage, qui sont utilisées pour permettre au CE de recevoir des données au moyen d'un second PE, le premier PE et le second PE étant tous deux des PE auxquels a accès le CE, et les premières informations de routage comprenant le surdébit de routage du chemin de routage direct entre le premier PE et le CE. La présente invention se rapporte au domaine technique des communications.
(ZH) 本申请公开了一种切换路径的方法及装置,用于解决PE与CE之间的直连路由路径故障,下行数据无法在PE上进行转发,从而导致的下行流量中断的问题。该切换路径的方法包括:第一PE确定与CE之间的直连路由路径从可用变为不可用;第一PE发布第一路由信息,用于使得CE通过第二PE接收数据,第一PE和第二PE均为CE接入的PE,第一路由信息中包括第一PE与CE之间的直连路由路径的路由开销。本申请涉及通信技术领域。
