Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] The invention provides a fault notification method, which is suitable for encapsulating the fault information in a fault notification message when the main path of the IP multicast tree fails, and sending the fault notification message to the fusion node to solve the existing The method of sending fault notification messages by flooding in the technology increases the number of invalid messages and reduces the security performance of the network. Please...

Abstract

Disclosed in the present invention are a failure notification method, detection apparatus, forwarding apparatus, system and data structure. The failure notification method comprises: detecting whether a failure occurs in the main path of Internet Protocol (IP) multicast tree forwarding paths which are established based upon Protocol Independent Multicast protocol; when a non-switch node in the main path detects that a failure occurs in the main path, obtaining the failure information, and encapsulating the failure information in a failure notification massage; transmitting the failure notification massage to a switch node in the main path. According to above technical solution, in the failure notification method disclosed in the embodiments of the present invention, when the non-switch node detects that a failure occurs in the main path of the IP multicast tree forwarding paths, a failure notification message is transmitted to the switch node in the main path. Compared with the prior art, when the non-switch node detects that a failure occurs in the main path of the IP multicast tree forwarding paths, there is no need to transmit failure notification messages to all nodes in the multicast network which the IP multicast tree belongs to, and therefore the number of invalid messages is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication networks, in particular to a fault notification method, a detection device, a forwarding device, a system and a data structure. Background technique [0002] Multicast technology is a one-to-many multi-party communication technology. Compared with the commonly used unicast technology, the multicast technology reduces the duplication of data content by establishing an optimal multicast forwarding path, thereby greatly reducing the consumption of network resources by multi-party communication, such as IP (Internet Protocol, Internet Association) multicast tree. An IP multicast tree is a forwarding path established from one (or more) source nodes to multiple receiving nodes. The multicast stream bearing the video service is transmitted on the multicast network through the IP multicast tree, which can improve the forwarding efficiency. [0003] In order to avoid damage to service perfo...
