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 of the embodiments of the present invention, not all of them. 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 ne...

The invention discloses a fault notification method, a detection device, a forwarding device and a system. A fault notification method, comprising: detecting whether the main path in the forwarding path of the IP multicast tree established based on the protocol-independent multicast protocol fails; when a non-switching point on the main path detects that the main path fails, obtain Fault information, encapsulating the fault information into a fault notification message; sending the fault notification message to the switching point of the main path. As can be seen from the above technical solution, in the failure notification method disclosed in the embodiments of the present invention, when the non-switching point detects that the main path in the forwarding path of the IP multicast tree fails, it sends a failure notification report to the switching node of the main path. arts. Compared with the existing technology, when the non-switching point detects that the main path in the forwarding path of the IP multicast tree fails, it does not need to send fault notification messages to all nodes in the multicast network where the IP multicast tree is located, thereby reducing the number of invalid reports. number of texts.
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 and a system. 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 performance in the even...
