Embodiment Construction

[0018] 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 part of the embodiments of the present invention, but 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 creative efforts fall within the protection scope of the present invention.

[0019] BFD can quickly detect faults in the bidirectional forwarding path between two devices for various upper-layer protocols (such as routing protocols, etc.). Upper-layer protocols usually use the Hello packet mechanism to detect faults, which takes seconds. BFD can provide millisecond-level detection, which can speed up network convergence, reduce application interruption time, and improve network reliability.

[0020] BFD itself does not have a d...

Abstract

The embodiment of the invention provides a switching method and apparatus. The method comprises the following steps: if a state value of a first identification bit used for monitoring a first port state for transmitting a bidirectional forwarding detection BFD session in a register is detected to be updated to a first state value, determining that a first port is faulty; and selecting a port in member ports in which the state values of the identification bit are second state values and which correspond to an aggregation link so as to transmit the BFD session through the second port, wherein the second state value is used for identifying the second port as a normal state. By adoption of the switching method and apparatus provided by the invention, the fault sensing efficiency of the BFD session is effectively improved, the occurrence of unmeaning oscillation is avoided, and thus the resource utilization rate and the user experience are improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a switching method and device. Background technique [0002] BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) is a general, standardized, medium-independent and protocol-independent fast fault detection mechanism, which is used to detect the connectivity of links in IP networks and ensure that communication between devices can be quickly detected faults, so that measures can be taken in time to ensure the continuous operation of the business. BFD can quickly detect faults in the bidirectional forwarding path between two devices for various upper-layer protocols (such as routing protocols). [0003] Ethernet link aggregation is called link aggregation for short. By bundling multiple Ethernet physical links into one aggregated link, the link bandwidth can be increased. The bonding of physical links can be achieved by bonding Ethernet i...
