First, let us look
QoS necessary knowledge:
network protocol: TCP / UDP, TCP protocol requires a complete after a three-way handshake to complete,
各种女宝宝的发型 - Qzone日志, which is the current mainstream applications, such as looking web pages, the QQ, with the Thunder ... ... All these agreements will be used.
TCP (Transmission Control Protocol, Transmission Control Protocol) is connection-based protocol
TCP simple demonstration is as follows:
PC1 to PC2 connection request ---> PC2 response to the request (consultation delivery time )---> PC1 sends data after receiving consent
UDP (User Data Protocol, User Datagram Protocol)
correspond with the TCP protocol. It is the protocol for non-connected, it does not establish a connection with each other, but directly put the packet in the past,
XXXXX绿坝-花季护航 - Qzone日志! We often use the \Because the UDP protocol is not connected to the process and send the base point days, so it's communication efficiency; but also because of this, its high reliability as TCP protocol. QQ on the use of UDP message, so sometimes the situation can not receive messages.
IPP2P agreement: analysis of the specific characteristics of each package, filter P2P signatures. But efficiency is not high, so set the QoS in the following tutorial, I used multiple methods and accurate control of BT.
Layer7 agreement, based on the regular type of content. Determine the top-level analysis by which program to control the data sent, this is the advantage of linux. The disadvantage is to analyze more data packets,
new new balance shoes, and low efficiency, impact performance, while there may be other programs manslaughter.
protocol briefly here, to talk about the main block QoS objectives:
1, based on MAC
2, based on the port
3, based on IP
4, based on protocol
setup process (Figure 1):
QoS basic settings
open QoS enabled bandwidth management
given priority flag ACK SYN FIN RST
here I do not choose the whole, P2P software will generate a large number of ACK packets, if enabled will interfere with other programs.
ICMP to give priority to not vote for network testing, faster response, no help. Worried that some programs continue to send ICMP data interference network.
Strict Rule Ordering strict accordance with the rules is the order of QoS implementation in the 1.18 version that has not, and if so, on the other version first.
settings change automatically updated classification system enabled real time in order to see the changes effect.
default priority (level): select the lowest level the default QoS level, this refers to all the agreements have not been defined priority. This should be set inside the set with the classification determined, the default is low, I changed to the lowest level.
upload rate / data reference operator in fact limited to your package,
new balance shoes, in my case 1M down, 512k upload
maximum rate of 320 kbit / s
Do not mess
to fill in,
盗窟版至理名言（笑破你肚皮） - Qzone日记, it directly determines whether qos to work properly. QoS fill too large, then the network will send more than you can afford more data, so that network congestion, QoS has lost a role.
General ADSL 512kbit upload the theoretical value is actually used in the loss of about 10%, taking it to 70% to 90%.
If you do not know to use the Thunder and the BT high-speed downloads, and then look at the \
downstream rate limiting
1200 kbit / s the opposite, the speed of downlink always sooner the better, 1M 100M within the network for the downlink, it is really trivial, but also friends proposed to be located a great value, but for I am here to better control set 1200kbit / s
the most advanced 100%
High 90%
Intermediate 80%
lower 70%
lowest 60%
A Grade 50%
B Grade 40%
C-level 30%
D-level 20%
E-class 10%
this setting is to allow the application of high priority as soon as possible downstream, does not limit the use of low-level procedures for network speed.
save the settings, enter the category set
TCP / UDP
Dst Port: 53
Transferred: 0 - 2KB most advanced DNS
DNS is very important, be sure to set the highest,
new balance 574, and on top. Not the case when a large number of downloads, DNS packets may be sent does not go out because of network congestion, resulting in page can not access.
TCP / UDP
Src Port: 5800 Advanced VPN
I occasionally use the VPN,
new balance mens, to ensure a smooth set to High
TCP
Src Port: 2782,2752 Advanced Tdxw
This is the stock software port is set to Advanced.
TCP
Dst Port: 80,443
Transferred: 0 - 512KB Intermediate WWW
When the WWW application
intermediate response time less than 512KB, 512KB reduced to lower than see below
TCP / UDP
L7: qq
Transferred: 0 - 512KB low-QQ
L7 protocol based on low-level response when QQ less than 512KB.
UDP
Src Port: 6000-6020,8000 low-QQ
This is the QQ
common source port,
new balance sneakers, when L7 is not accurate in the low-level run again to ensure QQ
TCP
Dst Port: 80,443
Transferred: 512KB + low-level WWW (512K +)
camouflage port 80 to download now very large, when the traffic is reduced to 512K above the low-level
TCP / UDP
Dst Port: 53
Transferred: 2KB + lowest DNS (2K +)
DNS packets in general is not, so put into the lowest level of more than 2KB
TCP / UDP
Port: 21 lowest level FTP
FTP application to put the lowest level
TCP / UDP
L7: xunlei A class xunlei
L7 Protocol Analysis xunlei
set based on A-response.
UDP
Src Port: 3500,4863,4867,4881,4883,15000,26411 A class xunlei
This is xunlei
common source port, when the L7 inaccurate reassurance xunlei run on low-level
remember the election here and QQ are the source port
TCP
Src Port: 8000,36897 A-level xunlei
now have control of the control TCP UDP ports, if just select TCP / UDP, then many programs will be friendly fire.
TCP / UDP
L7: bittorrent C-level BT
L7 protocol analysis based on BT is set to C-level response.
TCP / UDP
Src Port: 25000,6881-6889 C-level BT
protocol analysis based on the port is set to C-level response to BT.
TCP / UDP
Dst Port: 36898-65535 B Grade Bulk Traffic
Bulk Traffic
a lot of friends that this plan is set, your other settings are invalid. In fact, the implementation of L7 protocol is preferred, and the end of the original rule is 1024-65535, common control. So here I was transferred to 36898-65535, set to B grade.
After the completion of the above,
new balance running shoes, the Internet and download the BT to things correct. We can be adjusted as needed. Reprinted Wireless Forum
elegant be the ultimate expression.
