[0003] However, due to the insufficient total bandwidth of the remaining member paths, all outbound traffic will be allocated to the remaining member paths during this period, which will cause traffic congestion and increase the transmission delay, which in turn will cause an increase in the retransmission of application layer packets, further aggravating the congestion phenomenon, and causing The overall service quality has deteriorated significantly

Embodiment Construction

[0028] 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. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. 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.

[0029] The current mainstream multipath load balancing methods are ECMP (Equal-Cost MultiPath, equal-cost multipath) and UCMP (Unequal-Cost MultiPath, unequal-cost multipath). Realize multi-path load balancing on local network elements to meet the requirements of mixed bundled traffic distribution of...

Abstract

The invention discloses a fault handling method and device for a load balancing path, and relates to the field of information security. The method includes: after detecting the change of the member path state, calculating the bandwidth sum of each effective member path in the current load balancing path; The traffic rate limiting configuration distributes the total traffic to each valid member path. In this way, path congestion caused by load balancing path failures is alleviated.

Description

technical field [0001] The invention relates to the technical field of data network multi-path load balancing, in particular to a method and device for handling faults of load balancing paths. Background technique [0002] In order to achieve load balancing of traffic in the data network, the forwarding traffic can be shared by multiple member paths at the same time, and when some member paths fail, all traffic is shared by the remaining member paths to realize route redundancy backup. [0003] However, due to the insufficient total bandwidth of the remaining member paths, all outbound traffic will be allocated to the remaining member paths during this period, which will cause traffic congestion and increase the transmission delay, which in turn will cause an increase in the retransmission of application layer packets, further aggravating the congestion phenomenon, and causing The overall service quality deteriorated significantly. Contents of the invention [0004] A tec...
