Embodiment Construction

[0035] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0036]In the embodiment of the present invention, the data distribution table of the uplink service engine TMI and / or the data distribution table of the first-level SE are maintained through the link detection package, so that the TMI and the first-level SE can automatically avoid link failures when distributing data packets. The data packets are blocked at some stage in the middle. Through the link status information reported by the first-level SE according to the last-level SE, the first-level SE can know all the link status information to the last-level SE. In this way, after a link fails, the first-level SE The level SE can know in time and select other intermediate SEs for forwarding according to the distribution table as a data packet, thus avoiding the technical defect of a certain intermediate SE being blocked due to t...

Abstract

A link state detection method is disclosed in an embodiment of the present invention. The method includes: obtaining link state information from the lowest level SE to the mid-level SE; notifying to the mid-level SE the link state information from the lowest level SE to the mid-level SE; obtaining accessibility information from the mid-level SE to the lowest level SE according to the link state information from the lowest level SE to the mid-level SE, and link state information from the mid-level SE to the first level SE; notifying the first level SE the link state information from the mid-level SE to the first level SE, and the accessibility information from the from the mid-level SE to the lowest level SE; obtaining the accessibility information from the first level SE to the lowest level SE according to the link state information and the accessibility information sent by the mid-level SE.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a link state detection method and system. Background technique [0002] With the rapid development of the Internet and the continuous expansion of the network scale, the applications on the Internet are becoming more and more complex, and the network traffic is also increasing very rapidly. Therefore, a switching system with faster speed and larger capacity is required. In order to meet the high-speed and large-scale traffic switching requirements, the switching network, which is the core of the large-capacity switching system, usually provides multiple available links between the source port and the destination port. The system dynamically selects an available link to transmit the data packet to the destination port. The above-mentioned system can be any processing unit, network device, switching device, related network or a combination of these devices; a data pa...
