ISP QoS LabIn ISP QoS Lab1-PQ Priority Queue (PQ, Priority Queue), four queues are high, medium, normal, and low Priority. Data packets are placed in different queues according to prior definitions. routers provide services in high, medium, normal, and low order. Only a queue with a high priority is empty before serving as a queue with a medium priority, and so on. This ensures that high-priority data packe

reading the document mentioned above. I personally think that although u32 match can match different protocols such as IP TCP ICMP and match such as IP segments and ports, it is not as flexible as iptables in the end, and u32 match is insensitive to Layer 2, this makes it more flexible and controllable to filter data using iptables/ebtables mark. For example, TC + iptables is used to set QoS for the outbound packet of IP address 192.168.1.1. The BPS

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You c

QoS Problem AnalysisCurrently, the public exchange Telephone Network (PSTN) and ATM network can ensure the service quality, while the IP network cannot guarantee the service quality. Therefore, in this section, we analyze the service quality problems of IP networks by comparing the PSTN and ATM technologies and networks. First, let's take a look at the service quality of the PSTN network.　　In PSTN, networks and services are not separated and are provi

time domain and airspace error hiding methods can be used. (3) A fault tolerance algorithm based on the feedback channel is a method in which the decoder obtains the error information and transmits it to the encoder for error processing through the feedback channel. It mainly includes: Error Code tracking, conditional ARQ, intra-frame/inter-frame encoding mode selection, and reference image selection mode. At the same time, in the source encoder, it has become a hot topic in the past two years

First you have to turn on QoS in the QoS settings and set the overall uplink and downlink bandwidth. The second is set in the QoS unit, which is as follows: (content is the QoS rule help information, take a closer look to understand) you need to set the following entry: enable: Rule status.

In the classification process of QoS, the most important thing is to configure different priorities for different packets, and sort the packets of inbound switches by priority, then, the switch executes the corresponding QoS behavior based on the priority value. The first step of data packet priority sorting is to classify data packets. Classification Rules can use the priority bits of the 802.1p priority f

Application description:A VPN is established between the branch AR1830) and the Headquarters R3640) through IPSec. In actual environments, AR18xx uses the PPPoE-Client dialing method to access the Internet, its Dialer port dynamically obtains the IP address from the PPPoE Server,This determines that the IPSec VPN between the PPPoE Client Branch and the headquarters has a fixed public IP address) can only be automatically negotiated by IKE. At the same time, in order to effectively and reasonably

Personally think that u32 match can match different protocols such as IP TCP ICMP, and match such as IP segment, port, etc., but after all, not as iptables more flexible, while u32 match for two layers of sense, which all make it through iptables/ebtables Mark aims to make the filter more flexible and controllable. For two examples, the first is TC + iptables to the IP address 192.168.1.1 packet to do QoS, limit bps to 2Mbit, allow burst bps
