What is QoS?
QoS (Quality of Service), a security mechanism of the network, is a technique used to solve problems such as network latency and congestion. It is necessary for key applications and multimedia applications. When the network overload or congestion, QoS ensures that important traffic is not delayed or discarded, while ensuring the efficient operation
QoS interpretation
You can add/remove quality of service (QoS) rules here to ensure that different bandwidth and priority are provided for each traffic. In layman's terms, it is limiting the bandwidth of each group to maximize the effectiveness of the limited bandwidth. Let cool users do not affect the download user download, so that game users do not download users and card down.
in the enterprise operations, often found with some servers or with some servers in the data synchronization, you will find that some of the traffic will be larger, in order to ensure the normal operation of the network, we can actually use Windows with the QoS to limit the bandwidth used to sync, Here I share how to do it:
1. Open the Group Policy above the server on which you need to set QoS, start-run-g
the real meaning of QoS is. The Chinese meaning of QoS is: Networking service quality. Specifically refers to the various communication or program type priority technologies that are applied throughout the network connection. QoS technology exists to achieve better quality
Internet access? Of course, the answer is no. Next, let's take a look at how Microsoft explains this problem.
QoS Problems in Microsoft's kb316666 knowledge base are explained as follows:
Like Windows 2000, in Windows XP, a program can also use QoS through the QoS application programming interface (API. All programs can share of the network bandwidth, except for
1. IntroductionThe evolution of network architecture and broadband technology have promoted and accelerated the evolution of traditional networks to the next generation network NGN. With the expansion of the network scale and the gradual expansion of applications, especially emerging businesses with real-time requirements, such as VoIP, video conferencing, multimedia remote teaching, and on-demand video streaming, communication networks are more and more required to provide efficient end-to-end

Client Support Program (for example, dynamicaccess of 3com) perceives the priority of an application when it starts. On each node of the network, the priority is set to 802.1 p on the LAN and iptos on the wan. The Hardware Design of A vswitch must support multiple queues, and services with different priorities are queued separately. For example, a data packet with a higher priority can pass through directly. Normal data packets with a higher priority are cached and transmitted when they are idl
In recent years, the mobile communication field presents the trend of data and broadband, WiMAX adopts multicarrier modulation technology, which can provide high-speed data service, and has the characteristics of high frequency spectrum resource utilization, high efficiency bandwidth utilization and large coverage range. The cost of WiMAX is relatively low, it can provide convenience for individuals, families and enterprises, excellent mobile multimedia broadband service and high-speed wireless
QoS is: Quality of service, quality assurance. In the case of insufficient network bandwidth, QoS is set to ensure that some important services can obtain sufficient network bandwidth. You can set the bandwidth ratio that each priority can get, and when the network is busy, the network bandwidth will be allocated according to the set proportion, ensuring the entire egress line, the important service through
Currently, Neutron has a QoS proposal (https://wiki.openstack.org/wiki/Neutron/QoS#Documents), but only the CISCSO and NVP plug-ins implement QoS features, Other plugins are not yet implemented. Therefore, if you want to do network QoS in neutron, there will be additional costs.First, realize network

a 1bit unused bit, but must be set to 0. The 4bit TOS represents the minimum latency, maximum throughput, maximum reliability, and minimum cost. Only 1bit can be set in 4bit. If all 4bit values are 0, it means a General Service. Rfc1340 [reynoldsandpostel1992] describes how to set these service types for all standard applications. Rfc1349 [almquist1992] corrected the RFC and described the features of the TOS in more detail.

Nowadays, the development speed of the urban community broadband is more and more fast. Large-scale community has telecommunications, unicom and other operators of optical fiber lines directly, smaller than the community generally take the "use of routers to share the Internet," the way to enjoy broadband services, but this approach is prone to a problem: the residential property sector can not prohibit residents of the internet behavior, But it is also fair to protect the size of the bandwidth
