In a recently done project on a Wi-Fi class, you need to implement a function similar to a universal key in clicking on a Wi-Fi jump to the system Wi-Fi Setup interface. Nonsense I will not say more, the following is the implementation of the Code.

address involves an ARP communication, and this mode is also the direct feedback to the client after the RS receives the packet, so the distributor has no bottleneck. This also requires a VIP to be configured on all machines.Three, LVS scheduling algorithm1.

Introduction of three operating modes and 10 scheduling algorithms of LVSWorking Mode Introduction:1.Virtual server via NAT (Vs-nat)Advantage: Physical servers in a cluster can use any TCP/IP-enabled operating system, the physical server can allocate reserved private addresses for the Internet, and only the load balancer needs a legitimate IP address.Cons: Limited scalability. When the server node (normal PC server) data grows to 20 or more, the load balancer becomes the bottleneck for the entir

request processing time is 100ms, that is to say 1 php-fpm worker processing process in 1 seconds can handle 10 requests, 100 PHP-FPM worker processing process, 1000 requests can be processed.Of course, the need to combine server hardware resources to configure, if improperly configured, it is easy to peak in the request or traffic surges caused server downtime.Network bandwidthNetwork bandwidth will also be an important factor, if your service processing is very strong, but the user's request
the rotation method simply rounds 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 the nodes of each cluster are rotated to be selected in equal position. This algorithm is widely used in DNS domain name polling.The rotation activity is predictable, and the chance of each node being chosen is 1/n, so it is easy to calculate the load distribution o

This software has been rated as the most rogue software, now out of the second edition, has not bundled rogue software, the function is really good, my mobile phone video, or some very rare media format can be played.
Software Introduction:
New independent playback of the kernel, add: playlist, skin,
the screen hinges, they can also provide a clear, loud playback effect. When we play the test audio, we can clearly hear the vocals of the band. And, through the built-in Dolby Home theater V4 software, you can effectively improve the quality of the sound level, you can use the preset three models (movies, music and games), or the self-defined equalizer, to achieve more accurate sound effects.

5.2 Case Study
5.2.1 Program deployment Strategy on high-performance hardwareWe just need to ensure that the cluster has affinity, that is, the equalizer according to a certain rule algorithm (generally according to the
calculation and selection of IIR filter. For example, many of the filters in the speech coding are IIR filters, equalizer is generally used IIR filter. In other words, the real-time requirements are not very high occasions can consider the use of FIR filters, when the FIR filter order is longer, you can consider using FFT to calculate.
When designing IIR filters, the design index of the digital filter is usually transformed into the design index of t
