order to achieve optical IP (ipoveroptical). Micro-mirror Array optical switch technology based on MEMS (MICRO-ELECROMECHAN-ICALSYSTEMS) technology is also a hotspot in recent development. The use of MEMS technology in optical networks has the advantages of low cost, high speed, small volume, large communication capacity, small volume, flexible variable, transparent bit rate and protocol, and increasing network speed through electronic restriction. But the current switching speed is not up to

utilization rate of the band, minimizes the error and noise, and improves the system's transmission capacity. Because the frequency band of the sub channel is very narrow, the cable properties can be considered linear, so the pulse aliasing can be reduced to a minimum degree. Although the energy from the pulse interference can affect the reception of the signal, the effect of FFT can be extended to the various sub channels in the FFT window, so the effect is greatly reduced.In addition, the cha

With the Nginx agent, the backend server restart on the user upload effect reduced to the extreme, and Nginx is very stable does not need to restart it often, even if the need to restart, the use of kill-hup can be achieved uninterrupted restart Nginx. 3 asynchronous transmission can make the load balancer more secure, why do you say so?

Lvs-nat mode: LVS-DR mode: Lvs-tun mode: Virtual server via NAT (Vs-nat) Advantage: The physical servers in the cluster can use any of the TCP/IP operating systems, and the physical servers can allocate the reserved private addresses of the Internet, and only the load balancer needs a legitimate IP address. Disadvantage: limited scalability. When the server node (normal PC server) data grows to 20 or more, the load balancer becomes the bottleneck for the entire system, as all request package

The difference between neural network and support vector machine The support vector machine (Support vector machines, SVM) developed in statistical learning theory is a new universal learning method, which shows the advantages in theory and practice. SVM has a very good generalization ability in non-linear classification, function approximation, pattern recognition and so on, and it is free from the bondage of building learning machines from the perspective of biological bionics. In addition, t

First, the concept: Sharding (sharding) refers to the process of splitting a database and dispersing it across different machines. Spread the data across different machines without the need for powerful servers to store more data and handle larger loads. The basic idea is to cut the set into small pieces, which are scattered across several slices, each of which is responsible for only a portion of the total data, and finally a equalizer to equalize ea

-information (routing, sharding). The mongos itself does not have a physical storage Shard server and data routing information, but is cached in memory, and the configuration server actually stores the data. MONGOs the first boot or shutdown reboot will load configuration information from config server, and if configuration server information changes will notify all MONGOs to update their status, so that MONGOs can continue to route accurately. In a production environment, there are typically mu

Label:What is a shard Sharding refers to the process of splitting a database and dispersing it across different machines. Spread the data across different machines without the need for powerful servers to store more data and handle larger loads. The basic idea is to cut the set into small pieces, which are scattered across several slices, each of which is responsible for only a portion of the total data, and finally a equalizer to equalize each shard.

Equalizer IO will not receive large traffic impact.5, a wide range of applications, because LVS work in the 4 layer, so it can almost all applications load balance, including HTTP, database, online chat room, etc.The disadvantages of LVS are:1, the software itself does not support regular expression processing, can not do static and dynamic separation, and now many sites in this area have a strong demand, this is the advantage of nginx/haproxy+keepal

open source software.LVS is characterized by:1, strong anti-load capacity, is working in the Network 4 layer only for distribution, no flow generation, this feature also determines its performance in the Load Balancer software is the strongest; 2, the configuration is relatively low, this is a disadvantage is also an advantage, because there is not much to configure things, so do not need too much contact, Greatly reduce the chance of human error, 3, the work is stable, self has a full foot bat

The rotation method is simple in order to rotate the selection in this group of members.In a load-balanced environment. The equalizer rotates the new request to the next node in the node queue, so that it is continuous and cyclical. The nodes of each cluster are chosen in the same position. This algorithm is widely used in DNS domain name polling.The rotation ac
