QoS service is the essence of network technology, it is different from VLAN, different from ×××, its role in the network is very important, but also very large. May just start contact with the network, do not feel, also do not touch its importance, but with the work experience, the more later development, experience has a certain small success, found that Qos service is really good and important, there is a feeling of late encounter, it is true. Because some small companies that you just started to contact feel that there is nothing, and slowly contact some big companies, and find that many things are used, you will slowly find that your company's network is always insufficient, always overwhelmed, and difficult to manage, so you will definitely find ways to solve this very important and critical problem. Today, I will talk about this matter from some management software and hardware aspects.

soft management

I am no exception, but also because there are defects in the network, will consider so many things, now end a software, it is dedicated to solve this piece of Qos service, website address: www.grablan.com/

I think this software is still good, I also simply tried it, because it is charged, many functions can not be achieved, only free experience 2 hours, so I did not feel anything, but I used one of the USB interface disabled, I think this is quite powerful, has been enabled, found that others plug in the U disk on my computer does not respond, this is really good, another is that I found a software in it, you can optimize your laptop, I think it's quite useful. It's this Mini programs.

We can take a look at these red processes, which are the processes that our computer is running. Through this, we can directly see that those processes that are not usually used are opened. At this time, we can combine the services.msc service to change the ones that are not usually used to disabled or manually enabled. This way, we can make it waste less computer resources. In addition, we found that it can monitor each child process and view the resource consumption of the child process. Very clear.

Take a look at network behavior management

allocation strategy

P2P download restrictions

AD Active Directory is different from Workgroup. To a certain extent, it can also play a very good role in computer management. Basically, it can distribute, update, notify the entire network, and remotely synchronize computers. It is equivalent to the isolation of vlan on the network. AD domain environment is more secure than Workgroup, and the management of the network is also more. For example, Exchange 2010, Fortegrate Firewall, Lync Language Phone, etc. are very closely coordinated. There are also domain file sharing services DFS, as well as access within the domain, etc. Basically, 70%~80% of the functions of the computer above can be implemented and managed through the domain, but it cannot restrict traffic and monitor traffic in the network. This is a matter above the network. I just mention here that there are policies, but the policies are different.

PRTG Network Monitor Freeware

It only plays a monitoring role and cannot limit traffic. This needs to be done in conjunction with other software.

hard management

Speaking of hardware management, I introduce several network behavior managers here. The first one is Deep Convince. This software is really powerful. The second one is Netcom, which is also very good. 3. Huawei's firewall has also been activated to certain protective measures. 4. Flying Tower Firewall. These are very good hardware management software.

Another Internet behavior management is to install national security monitoring, which is generally installed in large hotels. In fact, it is necessary to configure port mirroring on the core three-layer network management switch to synchronize data to the Linux server. The national security side collects and monitors information.

About Qos service is roughly introduced here, and there is time to introduce some of its common working modes and their principles in detail.
