一种隧道丢包检测方法、装置及网络通信设备
Abstract:
(EN)
The present invention provides a tunnel packet loss detecting method, apparatus and network communication device. The transmitting frequency of transmitting detecting request packets at a head node is improved, and the quantity statistic and report of transmitted and received packets are performed at each node in a tunnel, so that a quick and exact tunnel packet loss detecting is achieved. The present invention can be applied in a two-way tunnel and a one-way tunnel, and can perform a statistic of transmitted and received packets in a tunnel for each node in a link, and therefore the specific packet loss location and quantity can be exactly determined, and the network fault point can be quickly located. A much convenient way is provided for the engineering maintenance, and requirements of the network operation and maintenance can be satisfied.
(FR)
La présente invention concerne un procédé et un appareil de détection de perte de paquets dans un tunnel, ainsi qu'un dispositif de communication en réseau. La fréquence d'émission de l'émission de paquets de demande de détection au niveau d'un nœud de tête est améliorée, et la statistique quantitative et le compte rendu de paquets émis et reçus sont effectués à chaque nœud d'un tunnel, de sorte qu'une détection rapide et exacte de perte de paquets dans le tunnel est réalisée. La présente invention peut être appliquée dans un tunnel bidirectionnel et un tunnel unidirectionnel, et peut effectuer une statistique de paquets émis et reçus dans un tunnel pour chaque nœud d'une liaison, et le lieu spécifique et la quantité de perte de paquets peuvent par conséquent être déterminés de manière exacte, et le point de défaillance du réseau peut être rapidement localisé. Une méthode très commode pour la maintenance technique est décrite, et les exigences d'exploitation et de maintenance du réseau peuvent être satisfaites.
