Experimental Study on the Performance of Linux Ethernet Bonding

摘要: Linux bonding is a feature allowing to group multiple physical network interfaces into logical one on machines. Known as low-cost method improve fault tolerance and throughput, the with seven supported modes increasingly deployed in various scenarios such datacenters, home networks, etc. However, strengths weaknesses of different have not been well investigated. While previous works mostly pay attention performance popular round-robin mode, this work extensively additionally evaluates other based three major criteria: throughput improvement, load balancing, tolerance. To best our knowledge, first investigating capabilities using bonding. The evaluation results show that active-backup mode achieves flow switch-over time, which duration traffic discontinuation due failure, small 10 milliseconds. Moreover, two bonded interfaces, machines can achieve maximum close double case non-bonding. out-of-order switch compatibility issues may limit utilisation certain scenarios. In 802.3ad issue be avoided, although balancing always optimal.
