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

During Enterprise O M, we often find that the traffic increases in some cases when synchronizing data with some or the same server. To ensure the normal operation of the network, we can actually use the QOS provided by windows to limit the bandwidth used during synchronization. Here I will share the following operations: 1. Open the Group Policy on the server that needs to set QOS, start-run-gpedit. msc2.

Application descriptionPurpose: Enable NAT and QOS at the same time on AR1830. The data stream sent from PC1 is defined as 5 with a Gold priority. at least 50% of the ADSL bandwidth must be guaranteed; data Streams sent from PC2 are defined as multimedia (priority 3). At least 20% of the ADSL bandwidth must be guaranteed; Network Management (Priority 7) must ensure 10% of the bandwidth, but when the network is not busy,Each data stream can exceed the

Cisco's QoS speed limit and h3c a little difference, but overall, h3c of the comparison slag, the unit is not the same, the H3C car unit is KPBS, and the Cisco Police speed limit unit is bits per SECONDS,H3C this skipped.

From: http://mybroadband.co.za/vb/archive/index.php/t-18042.html There are 4 commands used to set the QoS: At + cgeqminAt + cgeqreqAt + cgqminAt + cgqreq These commands set the QoS "window" that will be used to check ifConnection can be accepted. Let say you set the following QoS window: Min 64 K (d) 32 K (u)REQ 144 K (d) 64 K (u) The network will then accept th

Strictly speaking, cos and ToS are only a tag mechanism of QoS.The QoS range is too large, involving the marking and classification of the incoming data stream and the speed limit, the congestion avoidance and management of the network backbone, and the queue scheduling mechanism at the network egress.Cos indicates the priority of L2 isl or 802.1Q data frames. The value ranges from 0 to 7;TOS is the service type tag of layer-3 data packets, which is a

inter-frame encoding macro block. The intra-Frame Prediction macro block is not the same as the intra-frame encoding in H.263, the predicted intra-frame encoding method is more efficient than the non-predicted intra-frame encoding method, but it reduces the re-synchronization performance of intra-frame encoding, you can set the intra-Frame Prediction flag to restore this performance. (2) There are two types of clips that only contain intra-frame macro blocks, one is intra-frame (I slice), and t

There is a bit of crooked nuts on the forum sigh "Cisco router QoS project monitoring is always painful", admittedly, the general router traffic monitoring, using cacti to do, and due to the different upgrade version number, and the router iOS version is different, and very difficult, Some programs even need to TFTP download the written TCL script to the router operating system to perform, to cooperate with the retrieval.After 2 months of continuous g

In the process of enterprise operation and maintenance, often found with some servers or with some server data synchronization, you will find that some of the time the traffic will be larger, in order to ensure that the network is running, we can actually use the QoS of Windows to limit the use of synchronization bandwidth, here I share its operating methods: 1. Open the Group Policy above the server on which you need to set

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.

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 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.
