network tap aggregation

In order to achieve network redundancy, on the host side of the ESXi6.7, the network port of two running traffic is done teamning:On the switch side, the corresponding two switch ports do port aggregation Channel-group:After the completion of the virtual machine on the ESXi host Ping does not pass to the switch, after the discovery is the ESXi host on the teaming

data, the loss of resources can be largely negligible.) ）about Search:This program search is based on Coreseek Chinese open source framework, billion-level data, search millisecond level.about crawlers:This crawler is based on PHP Snoopy class write a crawler, updated the crawler trigger, the original Web trigger mode changed to the command line trigger, optimized the crawler timeout problem.new Crawler added 3 features:1. Added crawler-routed function2, added the use of proxy IP function3, add

address rollup Configuration instance, the topology diagram looks like this: R2 connected to multiple network segment address (especially this kind of continuous IP address is the most should do network summary), the same R4 also configured a lot of network segment information. r2 r1 " between OSPF protocol area1 area, r1 and R3 area0 backbone area

Minimalist notes Path Aggregation Network for Instance segmentation Paper Address https://arxiv.org/abs/1803.01534 The core of this article is to propose a network panet for instance segmentation, as shown in Fig. Three improvement:bottom-up Path Augmentation After FPN, add the convolution operation from bottom to top. The article explains that before the FPN sk
