Original from: http://blog.chinaunix.net/u/9284/showart.php?id=220696 use TC for flow control (Qos) (2006-12-13) Kang Daoyu Objective: I see the network on the Linux system flow control article a lot of not practical, even if the reference can not quickly write traffic control rules, and there are many errors. I have also written an article, is a lot of web sites cited, thanks to my support, I put an example to write out for everyone to reference

This article explains the mechanism of Ioband The Ioband principle is simple: the Ioband device sets many group, each group has its own weights and thresholds, and Ioband drives QoS control for these group IO requests. Ioband devices are controlled based on token, and different token are allocated according to group weights. The strategy also includes the request based and sector based token control Dm-ioband involves several important data structures

This article explains the ioband mechanism. The ioband principle is simple: the ioband device sets many groups, each of which has its own weight and threshold value. The ioband driver controls the QoS of the IO requests of these groups. Ioband devices are controlled based on tokens and different tokens are allocated based on group weights. The policy also includes request-based and sector-based Token control. DM-ioband involves several important data

, the DBA will gradually increase the video bit rate. On the contrary, if DBA continuously detects packet loss, it will not adjust the video bit rate, but will continue the call. Therefore, DBA is suitable for packet loss environments caused by network overuse or throughput problems. When the systems of all parties involved in the call do not support LPR, you can use the video error concealment (PVEC) function. PVEC is an algorithm used for IP video quality of service (

Bcm56133 chip supports four QoS modes: Port-ID-based, MAC address-based, 802.1 p-based, and DiffServ-based priority settings. Registers based on 802.1 p and DiffServ priority settings are quickly found in register definitions;The Port-based priority setting register is in the 802.1Q VLAN section.. ConfigurationQoS pause enable register registers will be encountered during the configuration process, and later I will understand its role: (Before depart

Article title: LINUX route and QOS speed limit. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I have been paying attention to and trying LINUX for a long time, but it is rarely used. I just need a vro in the unit, and I have an idle old host to improve my practical ability! There are a lot of mistakes in online a

Define the host range for which you want to limit the speedS3760> enS3760 # confS3760 (config) # access-list 101 permit ip host 192.168.1.101 any ---- Define the IP address for Speed LimitS3760 (config) # access-list 102 permit ip host 192.168.1.102 any Step 2.

Some enterprises want to configure specific users, such as special internal network users such as managers and directors) large bandwidth is provided, the internal network selects a specific WAN to access the external network, and the specific lines are left to specific users. The above functions can be achieved through QoS bandwidth management.The Qno xiaonuo router allows you to select a single IP address, a series of IP addresses, or an IP group of

Some enterprises have complicated network settings and do not want to change their routing devices. We also want to use smart QoS functions and behavior management of wayos. What should we do at this time? Tell you: the new version of wayos has a function called transparent bridge. This function is also explained by the Alliance, that is, as long as the wayos is directly connected to the network, let the traffic pass through from him. Other devices d

When QoS is implemented, traffic-based features are first classified and different levels are marked on the edge of the network; NBAR: an advanced classification method that supports high-level application information classification; Layer

QOS configuration of the S9300 port of the Huawei S9300 switch the queue scheduling mechanism. Each physical port has eight sending queues. The queue 7 has the highest priority, and the queue 0 has the lowest priority. The sending port supports PQ, WRR, and DRR scheduling methods, and hybrid scheduling of PQ + WRR and PQ + DRR. When www.2cto.com is used for hybrid scheduling, packets in the PQ queue are first scheduled. The highest priority queue is f
